This app will show you if you have F2FS. (You'll need to toggle it in the settings though). But it's not difficult to do. Be aware that cache will stay on EXT4. https://play.google.com/store/apps/details?id=me.kuder.diskinfo&hl=nl
Get the app, DiskInfo:

A little confusing, so pay attention. Press on the section you want to see, which is data or user data. It will show filesystem type.
I opened my new OP3T and updated it. It was on F2FS from the get go after that.
I believe an app like DiskInfo (Link) is capable of viewing what format it is. Going by the screenshots the format is listed as File System.
The bloatware is stored on /system a partition you cannot modify be default. All Google approved Android phones have a clear distinction between /data and /system. When you look at available space that's the space on /data not /system, there are special apps that can find the the available on /system but that usually doesn't effect the user (an example of such an app: https://play.google.com/store/apps/details?id=me.kuder.diskinfo&hl=en_US). Since all of your apps exist on /data, not /system.
​
For example a phone may have an 8 GB storage chip. This will be divided into probably 10 small partitions, /system and /data. /system is usually in the realm of 1 GB, it contains the android system and apps that are included with the android distribution. This includes the dialer, SMS client, launcher and the services that the phone manufacturer has chosen to bundle with their device. These apps don't have to be distributed through Google Play and therefore don't need to obey Google's restrictions. The ~7 GB left over would be dedicated to the users apps and data including updates to bundled apps (that aren't part of a system upgrade). This is where Spotify stores music when you save music to your device, or if Spotify wasn't bundled, where it would reside. If you check your available storage you would only see that ~7GB (/data), since you cannot choose to store anything on that ~1GB (/system).
​
When you factory reset your phone you don't want it to delete your dialer and your manufacturer has decided that even if you don't join Google Play you may want these other apps. However they don't use any storage on /data if disabled and without repartitioning, a somewhat scary prospect on a phone that could brick it, you cannot reclaim the storage that would be freed up by removing them.
Yes it is possible, but it may not help you entirely. Please have a look at the second stickied post for some more information.
Maybe you can see the current details of your internal storage via this app: https://play.google.com/store/apps/details?id=me.kuder.diskinfo
If you're still inclined to root, please provide us a model number and a build number if possible. :)
To add to that since this is the top post: In my opinion it's a noticeable difference over the ext4 file system. I only recommended doing it in the op since we were already wiping the phone to unlock the bootloader. If you already have f2fs, I personally think you're fine. The 3t came with f2fs and the 3 shipped with it after December 2016. You can check what file system your "data" partition has by using this app: https://play.google.com/store/apps/details?id=me.kuder.diskinfo&hl=en
The other partitions are ext4 since they don't benefit really at all from the f2fs improvements.
Well, the One Plus 3t shipped with f2fs, and the One Plus 3 started shipping with f2fs after December 2016 and was shipping with ext4 before December 2016. However, they claim there are additional improvements using the 3rd party f2fs over the stock f2fs.
That said, as long as you're on f2fs, you're probably good to go. I don't think the additional performance improvements are worth wiiping your internal storage unless you're already wiping the it (like we do when we unlocked the bootloader in my guide). If you're still on ext4, i would highly recommend getting on f2fs.
This is only for the "data" partition on your phone. All the other partitions (system, cache, etc.) will be ext4 since they don't really benefit from the f2fs file system change.
You can check what type of file system your data partition has by downloading this app: https://play.google.com/store/apps/details?id=me.kuder.diskinfo&hl=en
Download an app like Disk Info and see what your partition spacing looks like. See if one of the partitions is low. I don't really have any other ideas to shoot.
IIRC means "If I Recall Correctly", it's not part of the app name :)

Hmmm, difficult for me to say what to do here, usually i'd have root on hand to do such things or an adapter. Can you pop the card into one of the phones and use this for example to see what it says about the card?
Install this app. Then post a screenshot of the internal storage layout shown in the app. u/MishaalRahman would this work ?
That second screen is not indicative of ext4. A quick way to find out is to download and open DiskInfo, click on Data, and check the 'File system'.
There's DiskInfo
Nothing else. With the DiskInfo app.
User this app
Diskinfo works. Titanium Backup will also show you the size of /system and how much space is left.
Can you install diskinfo app https://play.google.com/store/apps/details?id=me.kuder.diskinfo and share a screenshot of the main screen please?
They use some swap partitions (zram)+real ram to shows free ram. You can check real free ram by download this app.
