[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] GTab10.1:
Ya I know, this may seem like a stupid question, but believe me I have valid reasons for asking it. So I have a Galaxy Tab 10.1 WiFi (GT-P7510) that had been sitting around not being used for quite some time. I decided to recently take it out and root it to run the snapprefs xposed module alongside snapchat. Well, first things first, the tablet was running Android 3.0 Honeycomb which is way out of date. I upgraded to the last update available for this tablet which was Android 4.0.4 ICS. through standard system update. I then rooted using CWM recovery and flashing over superuser. All worked well and the tablet was rooted. I installed the latest version of snapchat from the play store and attempted to login with ABSOLUTELY 100% VALID credentials. It went through the processes "logging in, verifying device, etc." and then crashed to the home screen. I tried uninstalling, reinstalling, signing up for new accounts, switching google accounts on the device, creating new google accounts, making sure google accounts were syncing correctly, making sure time and date was correct, downgrading snapchat to older versions, EVERYTHING. Absolutely nothing worked. The funny thing is that when initially opening snapchat, it would have the main screen where you see your camera open and have snap/stories notifications, etc. Then it would finish loading and go to the login/signup screen (since no account was logged in). That was when the problems would occur. I'm even able to sign up for new snapchat accounts which would go through just fine (I would receive the email notification from team snapchat), but when it was time to go to the main snapchat screen it would crash the same way as when logging in. At this point I was convinced that snapchat simply had issues running on 4.0.4 or something. I decided to flash a custom ROM to solve this. The first ROM I flashed was Nameless 4.4.4 .. Again, EXACT same issues. I was like wtf?? I then flashed Omni 4.4.4 and yep, same exact issue. I then tried CM 10.1 (4.2.2) and again, same issues. I went back to completely stock ICS 4.0.4 using Odin and ya, same issues as the first time. I really don't understand at this point. I thought it could be snapchat account issues so I tried logging in and logging out with all accounts that I attempted on the tablet using my Galaxy S6 Active which worked completely fine, so it's definitely something with the device. I'm someone that can typically figure out things for myself through researching, but at this point I'm really stuck, and I had to join this forum for assistance. If anyone would be able to help, I would GREATLY appreciate it. Does anyone have a Galaxy Tab 10.1 WiFi (GT-P7510) that they are currently running snapchat on? This is the original 10.1, and not the 2 or 3, and so on. Would anyone know what could possibly be going on? I wouldn't think that it would take much to run an app like snapchat, and I would think that the Tab 10.1's hardware would certainly be more than capable of doing so. The latest version of snapchat requires 4.0 and up, so I wouldn't think the android versions that I used would be an issue. Even the stock ICS 4.0.4 should be able to run it just fine. CM 10.1 was 4.2.2 and the other 2 ROMs that I tried were Omni 4.4.4 and Nameless 4.4.4.

I look forward to any help that can be provided. Thanks ahead of time everyone.
