I ended up rooting, and putting an app on that trims the memory usage but even still it didn't work after a few hours.
I think it was this: https://play.google.com/store/apps/details?id=com.fifthelement.trimmer&hl=en
NAND fam, NAND. Samsung used shitty NAND until the S6 where they used (finally) some sort of ultra fast storage (UFS?) for the internal memory and then it finally became bearable. Since 4.3, Android would have TRIM/garbage collection functions, so it did become a bit more bearable, but it was still the low quality of the NAND that was detrimental to the slow I/O performance.
For those of you who are rooted and are running a phone from 2013 and before, I'd recommend this https://play.google.com/store/apps/details?id=com.fifthelement.trimmer&hl=en
Set it on twice a day and you'll see how blazing fast your phone is.
Tried this? IIRC, the issue with the storage on the N7 was that garbage collection didn't work, and issuing a trim command fixed it for most people.
Try TRIM-ing the NAND (requires root)
https://play.google.com/store/apps/details?id=com.fifthelement.trimmer&hl=en_US
https://play.google.com/store/apps/details?id=com.fifthelement.trimmer Do this like once a week and your tablet should never slow down again unless you install a bunch of crap onto it. Also you should be able to run LineageOS 14.1 just fine. My Moto G with a Snapdragon 40 worked fine with it.
Which OS version did you load? They pushed the N7(2012) up to Lollipop (LMY47V, version 5.1.1), but it runs better if you stop at KitKat (KTU48P, version 4.4.4).
Then just run a file system "trimmer" such as this every so often. How often depends on how much data you move around. Light use weekly; heavy use daily.
/uj Seriously though, stay away from these RAM cleaners (esp the ones with those fancy animations), they’re most likely infested with adware/spyware and do more harm than good. Greenify is your friend. And if you have root, then either Trimmer (fstrim) or SSD Boost is a must have as it helps minimize writings on your phone’s SSD, thereby reducing lag.
You could try to trimm your storage. I have never tested this out on my OP3 since I didn't have to but it's a try. You do need Root for this though. https://play.google.com/store/apps/details?id=com.fifthelement.trimmer
This executes the TRIM command on your phone's solid state storage just like on desktops/notebooks and their SSDs that require this command to be kept in top shape for their lifetime. This way you reduce stuttering as the underlying NAND is properly managed by the storage controller.
Android TRIMs flash since 4.3, but sometimes it's good to do it manually. It can be configured to be done every x days in the background. Have a look for the effect of this kind of app in old tablets like the Nexus 7, their performance got restored to day one... just by taking care of the flash storage as it should be.
Here's my tip for making the device run just as new, software wise: Use this little app: https://play.google.com/store/apps/details?id=com.fifthelement.trimmer&hl=en
I recommend you run this every 2 weeks to a month. However, it requires root.
Brought my Nexus back to life recently and messed around with a bunch of ways to try to get 5.1.1 running nice.
I found 5.1.1 doesn't slow down too much if you have trimmer running twice a day ( https://play.google.com/store/apps/details?id=com.fifthelement.trimmer&hl=en_GB ). Changing the kernel to Franco ( https://play.google.com/store/apps/details?id=com.franco.kernel.free&hl=en_GB ) and then converting everything to F2FS did speed things up a bit and means you don't need Trimmer running, however it's a lot of fiddling to get everything converted to F2FS for stock.
Currently running cyanogenmod 12.1 (5.1) on F2FS, which is running quite well but the nexus runs extremely slow if I try to download something and use another app at the same time.
Currently considering just rolling back to 4.4....
There are no such thing (harddisk defrag) in Android, but.. You can trim it, i use this app
Other ways you could improve file system performance is thru modifying I/O Scheduler you can use KernelAdiutor for this.
Both need root
If you're not rooted, just use your phone as usual, for browsing porn, facebooking, displaying ads, etc.
How many years have you been using it? The eMMc memory has a limited number of write cycles. It's the same "vintage" (2012) as my Nexus 7. I found that going back to a KitKat based ROM (stock 4.4.4 in my case, but Cyanogenmod 11.0 would work too) improved performance as well as running a "trim" on memory every week or so.
You can find the manual "trim" program I use in the Google Play Store here.
If you are rooted run this app. It runs Trim on the file system, which LG doesn't do enough. It will speed up everything. Trim is an important process for SSDs, it keeps performance fast. Look it up.

This app works wonders in keeping the Galaxy Nexus working snappy:
https://play.google.com/store/apps/details?id=com.fifthelement.trimmer&hl=en
I usually run it on a monthly basis otherwise I find that my phone gets a bit laggy.
Edit: It seems like you need the phone to be rooted for the app to work, unfortunately.
I am trying to erase data.
Some are full files some are thumbnails.
​
>Can it recover the files after a TRIM and a reboot?
Yes, I ran https://play.google.com/store/apps/details?id=com.fifthelement.trimmer and did a reboot
Tried this https://play.google.com/store/apps/details?id=com.fifthelement.trimmer&hl=en_IN&gl=ES but doesn't work
The problem is that OS is not TRIMming the FS. As the result, flash drive controller starts working very slow. You can trim it using custom recovery, or if you root your device, you can install utils to trim it while running the system (like Trimmer). I prefer not having root, so I just enter commands manually once in a while in TWRP.
You can do the following if you are paranoid (I actually did this when I sold a phone):
- Remove your SD card, if applicable.
- Perform a factory reset. Make sure to format internal storage (if your device has separate storage for apps and user files).
- Use a method of your choice (app, terminal, etc.) to write zeroes (or random characters) to your device's internal storage (app and/or user data) until they have zero bytes of free space.
- Delete the files.
- Perform a full factory reset again.
Here is an example ADB shell commands to wipe free space in /data partition without root (Android Debug Bridge, ADB drivers and USB debugging mode required):
cd /data/local/tmp dd if=/dev/zero of=tmp1.bin bs=1048576 dd if=/dev/zero of=tmp2.bin bs=4096 rm tmp1.bin rm tmp2.bin
You can also use Total Commander to change directory to /data/data/com.ghisler.android.TotalCommander and run the 2 dd shell commands there (no root, ADB or debug mode required).
Alternatively, if your phone has root access, use this app.
Also, see this.
Every device is a slowly degrading device. Nothing last forever. The current OS in the S3 should already be "trimming" (lightly), but you can always root and run something like this if you want a more aggressive "trim". What you gain in "speed", you will lose in total capacity. It's a tradeoff I haven't found the need for on my S3.
Running a factory reset will also "speed up" a device. It's all subjective though. If you feel the device is too slow, buy a different (newer) one.
Well the other thing i was going to try to trim
https://play.google.com/store/apps/details?id=com.fifthelement.trimmer
But it's only for rooted phones as it's brought my old devices back to decent speeds
If you've been using it heavily for four years, the flash memory might be wearing out (it degrades with heavy amounts of reads and writes). No amount of reloading firmware will fix that.
OTOH, you may just need to run fstrim manually to free up more empty space on your device (flash memory works best on a half empty drive). Flash memory performance will slow down over time and might be causing your shutdowns. I doubt it'll fix your issue, but it's free. You need root to run fstrim with something like this though.
Maybe try deleting as many files as you can?
You could probably do worse. If you want to split the difference (about $250 used/$450 new), the Galaxy Tab S3 is great, but it's probably overkill for your use.
Your issues are probably with the Nexus 7 mostly. Between the flash memory degradation over time, and the earlier OS version; the Udemy app isn't dealing well. Do you ever run a "trim app"? That always "refreshed" my old N7 somewhat.
I read somewhere that it does it very rarely though. You supposedly can force it using this App:
https://play.google.com/store/apps/details?id=com.fifthelement.trimmer
I didn't try it though since my OP3 is still flying when it comes to performance so I didn't have a reason to.
Mine is still running pretty well probably because I mess around with stuff alot which means a complete wipe about every 8 months or so. Using an fstrim app speeds things up a bit and reboots make it faster when it gets slow. I'm just running CyanogenMod 13 with 6.0.1 because lineage OS 14 with 7.1.2 is much more sluggish. I would just use the stock ROM but I wanted the livedisplay night filter. 1080p YouTube is nice and smooth with no lag at all.
One odd thing is that my father's Nexus 7, which is fully stock, was extremely slow like the launcher was visibly lagging and it stayed that way through reboots. One day I rebooted it again and suddenly it was fast again. Can't explain why but anyway, I recommend downloading the stock ROM from Google and doing a full flash, then rooting and installing that fstrim app I linked. Feel free to disregard this and do whatever if you're experienced with this stuff. I wouldn't know if you were or not
/u/fifthelement80 developed a TRIMmer app to manually TRIM the storage, but I can't use it because of no root. Do you know if I can somehow check if Android successfully TRIMs on its own? It's supposed to have it after Android 4.3 but there are reports of it not working properly.
I use my MotoG with LOS 14 as my 2nd phone and while it isn't fast I wouldn't call it terribly slow.
Have you tried trimming the memory (fstrim. You need root for that, but it helped my old phone.
That said, it is nearly 4 years since the G2 came out. And mid-end phones have come a long way since then
How much free storage do you have left? Are you running EXT4 or F2FS? If EXT4, this app might improve storage performance: https://play.google.com/store/apps/details?id=com.fifthelement.trimmer
If F2FS, devs discovered that there is an issue with "garbage collection" on this filesystem, which can cause reduced write speeds and is also probably the reason why OnePlus switched back to EXT4 on the OnePlus 5.
You can try using trimmer. It trims your devices nand and it usually results in a boost for me. I just have it set to once a day auto trim.
When you say "constantly downloading updates" are you talking about the OS or apps? There hasn't been an OS update in ages (and you wouldn't want it anyway). The 2012 runs better on KitKat (4.4.4) than it does on Lollypop (5+). If you've already upgraded, consider going back to 4.4.4
If it's apps; is it the same app requesting an update immediately after applying one? In other words is it applying the same update over and over? You can tell for sure if you look at the version number in the Play Store before you update and noting if it's changing.
If it's the same updates over and over, your eMMc flash storage is buggered and isn't writing correctly anymore. That happens to all of the N7(2012)'s eventually. Most people see a lot of lag before that. Unfortunately, there is no good "fix" for that since the storage is part of the motherboard.
You can run "trim" apps like this one weekly to try to mitigate the problem, but it's just a band-aid.
Right now; it's third or fourth in my lineup, so I don't use it a lot, but it's doing OK.
The charging port on mine is getting "finicky". Some cables don't seat firmly and disconnect easily. I figure it's wearing out and will break before long. That seems to be one of the big points of failure over time with this model.
When it upgraded itself from KitKat (Android 4.4.4) to Lollipop (v5), performance went to hell and I rolled it back to stock KitKat. I tried some of the other ROMs (including Marshmallow, v6). None of them were an improvement over KitKat. There are some "custom" versions of KitKat (SlimKat, for instance), but I didn't find any compelling use case for myself to switch from stock in the end.
Finally, the eMMc flash storage wears out over time (cells go bad and get marked unavailable), sometimes occurring in system files resulting in bootloops and worse. I haven't had any trouble with that, but I run file system "trim" apps like this once a month or so to try to avoid them.
Your Mom's unit sounds a little farther along in the wear and tear department. I haven't been using mine heavily for several years.
Flashing the Nexus 7 though is a piece of cake compared to the HTC One S, if you use Wugfresh's Nexus Root Toolkit. You'd have to work real hard to bootloop it and I don't think you can brick it. The NRT has stuff to fix that.
I didn't really read into this, is basically it does what disk defragment does to windows pc's., I have this one installed. https://play.google.com/store/apps/details?id=com.fifthelement.trimmer
and rooting a nexus is quite easy, there are free software for rooting nexus devices, I used one and it required a few button presses and no knowledge.
Fulmics ROM solved all my issues. This phone is a speed demon now.
Also nova launcher and an all called Trimmer that does a trim on your SSD.
https://play.google.com/store/apps/details?id=com.fifthelement.trimmer
People are saying Fulmics which is great but not you want to keep the speed you need to not install trash and run this app
https://play.google.com/store/apps/details?id=com.fifthelement.trimmer
It runs Trim on your SSD. This is why most people feel the speed boost after a factory reset (plus the lack of apps)
if you are rooted check if running fstim improves the condition?
I am running CAF kylon build, feels snappy as the day I bought my nexus on launch.
https://play.google.com/store/apps/details?id=com.fifthelement.trimmer
I've been using Xposed, GravityBox and similar for a good while on a pretty low end device and have yet to experience any significant issues with slow down. No major resources or background processes seem to be occurring and all is very smooth for me. I don't think this is a common problem if you're smart about what you do. Avoid having similar modules activated that can cause clashes. For example if you have GravityBox and XBlast Tools activated at the same time you'll run into 'slowdown' issues and general wonkiness. I'd be looking at other culprits tbh. Make sure the framework's up to date. You could also try running this app and ticking all 3 boxes: https://play.google.com/store/apps/details?id=com.fifthelement.trimmer
Yes. Because this alone got rid of the lag on my G3. Feels like when i first bought it.
It runs Trim on the file system. Android does this automatically but not often enough.
https://play.google.com/store/apps/details?id=com.fifthelement.trimmer
Root and install an app called Trimmer. It runs the ssd equivalent of something like disk defrag but better. It should make a huge difference. Modern devices Trim automatically but the n7 doesn't.
https://play.google.com/store/apps/details?id=com.fifthelement.trimmer
It makes a huge difference on my G3 that doesn't seem to Trim often enough.
Try this. The bug that caused Android to not issue a TRIM command was supposedly fixed in 4.3, but it certainly couldn't hurt to try.
Try fstrim - see if that makes a difference. Root required.

In case anyone is interested:
I was running 5.0.2 and it was better than 5.0, but still not that good. Two days ago I installed the latest CM Nightly with F2FS (currently updated to the release from today) and it worked better. That was using GNL. I saw this thread and decided to get rid of GNL to see the difference and except for Google Chrome, everything seems faster now. I also reduced animations to 0.5x.
EDIT: Also use this. I found it in another thread: https://play.google.com/store/apps/details?id=com.fifthelement.trimmer&hl=en
Steps:
- Flash F2FS Recovery using fastboot and reboot into recovery and flash FormatPartitions.zip
- Reboot Recovery
- Wipe Data/Cache/Dalvik
- Flash Rom
- Flash Gapps (nano/pico)
- Flash journaling off script
- Trimmer (set auto trim every day)
Made some steps since I didn't know that many would upvote this.
Are you rooted? If so, install this app from the Play Store:
https://play.google.com/store/apps/details?id=com.fifthelement.trimmer&hl=en
Explanation of what the app does is in the link. I use it myself. Definitely helps.
Whether you're rooted or not, go to Settings --> Storage & USB and tap Cached Data. You'll get a prompt asking if you want to delete cached data for all apps. You sure do, so tap OK.
Next, find your way into your phone's recovery menu. If you're rooted, you're probably using TWRP. Tap Wipe --> Advanced Wipe and check off Dalvik/ART Cache and Cache. Make sure those are the only things checked off, or you're gonna have a bad time. Then swipe to wipe. After all is said and done, tap Reboot System.
If you're not rooted, the process takes a bit longer, but it's still easy. Power off your phone, then, while holding the Volume Down button, hold the power button. This will take you to the Bootloader. Use Volume Up/Down to scroll to Recovery Mode and press the Power button to select it. You'll see the Bugdroid on its back. While holding the Power button, tap Volume Up once and release the Power button. You should now see Recovery Mode options. Using the volume buttons, highlight "Wipe Cache" and press the Power button to select. Once that's done, highlight the option to reboot your phone. Apps will proceed to take forever to optimize.
After all is said and done, your phone should be running better than before. Don't get any of those optimizer apps that claim to make your phone better. One of the methods I mentioned above is among the best ways. Also, check for renegade apps (those that take a lot of memory, those that are always running, those that are constantly pulling data, etc.).
If that doesn't work, try a Factory Reset. If you go that route, I recommend doing it from Recovery (either TWRP or Stock). And if THAT doesn't work, maybe you should consider flashing the Factory Image from Google. If you've never done it before, XDA Developers and a simple Google Search will help you get started.
Hope one of these methods helps you get your phone back to a usable state.
Steps:

My tricks:
1) Get a good screen protector that has an oleophobic coating. This will restore the popping colours and contrast you had when you first got the phone before the coating wore off and all the smudges stayed.
2) Root and install Trimmer. An app that runs Trim on your ssd more often than LG does. This is want often part of what makes phones snappy after a fresh install. Look up ssd trim for more info on the process.
3) Uninstall or greenify Facebook, messenger, Twitter and snapchat. Just feel the difference and decide if they are worth it.
I don't know if you are on mashmellow but Fulmics 4.2 doesn't have the same ram management problems stock lollipop was having. I do swap batteries instead of charging though so my phone is rebooted every 24hr.
EDIT: BONUS TIP to keep the camera feeling fresh. Install LG XCam and the LG XCam settings app. It is the same as the stock camera but with access to all the settings.
Suggested settings (personal preference)
Image quality: 100%
Contrast: 6
Sharpness: 6
Noise reduction: Off
Edit 2: sorry the XCam link was for the G2 version. Fixed now.
Fa-i root pentru inceput si baga asta https://play.google.com/store/apps/details?id=com.fifthelement.trimmer
Since you have root, install this app and TRIM the data, cache, and system.
https://play.google.com/store/apps/details?id=com.fifthelement.trimmer https://play.google.com/store/apps/details?id=com.paget96.lspeed https://play.google.com/store/apps/details?id=rs.pedjaapps.entropy.app These needed rooted to make your beast smoother/snappier.
Try out Trimmer. I have it set to trim once a day and there's a noticeable improvement after using it.
Have you tried fstrim? This and BlissPop as my ROM made it usable again.
This is the app I was using but all of them require root. https://play.google.com/store/apps/details?id=com.fifthelement.trimmer
Well I guess the guy above meant this Trimmer.
I used PureNexus 6.0.1 (marshmallow) because the ParrotMod developer said that his mod doesn't work on Nougat. In thread I linked to before, the OP says that it does work for Nougat, at least the CrDroid build he used. Given that, I would be tempted to try his instructions first to potentially have a newer version of android that some are reporting runs faster.
Here's the links for the Rom + extras I used: PureNexus 6 Rom i used, XDA thread: https://forum.xda-developers.com/nexus-7/development/unofficial-pure-nexus-project-layers-t3243943 ParrotMod XDA thread: https://forum.xda-developers.com/nexus-7/orig-development/parrotmod-speed-2012-nexus-7-emmc-fix-t3300416 Kernel recommended by ParrotMod dev: https://forum.xda-developers.com/nexus-7/development/kernel-dc-kernel-t3310642 Fstrim for trimming the emmc storage: https://play.google.com/store/apps/details?id=com.fifthelement.trimmer

Which app are you using for that?
I used Trimmer (to trim NAND) and Dummy file Generator in sequence and repeated 4 times to solve a persistent hardware related phone freezing problem even when running different ROMs (incl. 4.3) after very clean installs including LineageOS: S3 Black Screen Freezing Fix
You might wanna try this
https://play.google.com/store/apps/details?id=com.fifthelement.trimmer
Defrag the Nand
I recently installed this app: trimmer but haven't used my tablet enough since then to know how well it works.
I used this app from the play store, but it needs root.
Try this app out. It just made my N6 a lot snappier after running it. Assuming you are rooted.
https://play.google.com/store/apps/details?id=com.fifthelement.trimmer
In addition to what has been mentioned yet, any fstrim app you can find on the play store to trim the storage. I use this one.
Also, reboot at least once every week to clear cache and restart any app that for stuck in the background and is draining battery. This is some general recommendation for every phone, and the newer Samsung phone even have an option to restart on specific days at night.
Edit: Also, is 50$/mo not really expensive for the G5? I don't know what's included in your plan, but summarized you pay $800-900 more than if you bought the phone. It's probably another situation as I'm in Germany, but here I'd pay €25-40 ($26-43) per month in almost every contract, depending on what is included in the plan.
