Have you tried changing the Product model to SM-G920K? If not, try this: Download Build Prop Editor and change the "ro.product.model" value to "SM-G920K" (without quotes), save and reboot. Also write down the original value so, if it doesn't make a difference, you can restore it to its default.
Edit: Mostly the problem derives from a difference in the rom base and the product model in the build.prop. I'm not sure if above works because I don't know your current situation, but I'm pretty sure you'll find your answer in that direction. Check out this if you're still on XtreStoLite Deo-Mod Edition 2.3
In your setting, go-to About > Status and scroll to the bottom and tell me if Device Status is Official like this
Also, go here to install a root checking app. This will verify if your device has been rooted.
I suspect it's been rooted by malware, but I have no way to confirm. Let me know what things say and hopefully we can get you back in order.
You can check your Knox status a couple of ways. 1. App 2. Booting the phone in "ODIN" or download mode by holding Power, Vol Down, and Home (or Bixby on newer models). Once it boots it will tell you to press up to continue or down to cancel. If in app or on the ODIN screen it says anything other than 0x0 by warranty void, your Knox is tripped and can't normally be undone short of maybe a full reflash which won't help your photo situation. I'm sure some people may have some alternative options but they may only make things worse as far as knox is concerned so it's hit or miss.
This is what I have have

Its similar to what you wanted and has a clear back, this with a screen protector has kepy my S6 safe for nearly two years.
I have this one from iOttie. I have not had to readjust the mounting and the phone is held securely. Easy to place phone in mount with one hand.
Just get a wireless charger for like $15. It's not as fast as the plugin Samsung charger but it's convenient.
Here is what I got, works just as well as the official Samsung wireless charger but costs much less:
I know this seems like spam, but you should definitely check out My160 on Amazon. Currently on sale or use the code BUYFOR20 and you can get it half price. http://www.amazon.com/Battery-Indicators-Kickstand-Attractive-Lengthen/dp/B00XISK8OO/ref=sr_1_1?ie=UTF8&qid=1441088301&sr=8-1&keywords=my160
I too have Jump (version 1) and I went with this case. It is thinner than I expected, but that is not a turn off what so ever. It is a nice solid case. I think its nice. I also got this screen protector. Its a lifetime warranty and fingerprints are virtually non-existent.
Well I think it ould work if plug it into a wall charger. I use this on my laptop which you cant do with most: http://www.amazon.com/WoodPuck-Compatible-Blackberry-SlimPWRcard-Qi-enabled/dp/B00P7ZVIHW/ref=sr_1_1?s=wireless&ie=UTF8&qid=1432018128&sr=1-1&keywords=woodpuck
It is also a great look for the office
I bought the soft version from Spigen [1] and it fits pretty well [2]. It does not come with a screen protector but it the edge sticks out a little in the front giving some protection to the screen.

Does your phone still have the Smart Manager (Settings > Smart Manager)?
If you do have some space left, you can also try the CCleaner app. It's pretty good at detailing what's taking up how much space.

Delayed because of all their bloatware slowing the thing down and draining the battery. Check out the reviews on this piece of garbage bloatware

14,295 - 5 star reviews yet gets 2.6 stars. Crazy.
> I just hate TouchWiz. It blows compared to stock Android.
This is my biggest fear with the transition. I'm OK with the S6 being smaller than the N6, and I am looking forward to a good camera again. I'm afraid im going to HATE touch wiz. I found a Google Now launcher that makes touchwiz look and feel like stock android.. if it comes down to it, I can root and run a custom ROM that is close enough to stock android.
You could try blowing away the email profile and setting it back up. If that doesn't work there are plenty other email apps. K-9 Mail is good lightweight app that supports encrypted emails.
