For the last three months i have been using a Samsung A6 Galaxy 8" Tablet and it's white coolur looks fantastic with the controller too up UNTIL i lost all video feed a week ago,i have tried everything and can't get video feed back, i mean i have litterly tried everything and no good. Yesterday i upgraded to FCC mode too and looking forward to trying that when weather improves but even booting everything up in the sitting room with the new app still no feed

but can anyone say why i may have all of a sudden lost video feed, it comes on fine until i take off and 30 seconds in to the flight i end up with a black screen, people are saying it's my tablet that's wrong but i don't agree because it has worked fine for three months.
Here is what i have done, sorry if i am going on about this topic on numerous threads but i really need some help with the problem cause now it's going to be risky too in FCC mode without video feed to my screen.Here is what i have done to try to resolve the problem.
-Discharged both batteries low and recharged (Cause i was only always topping up the controller battery so i felt a good discharge was needed on that)
- Fiddeled with settings on the Tablet as i was advised to uninstal google play store and try some more settings on the tablet to get more RAM...etc etc.
-Rebinding aircraft and controller used to fix this problem but not any more.
-Uninstall DJI GO APP and reinstalling
-Calibrating controller,gimbal and IMU.
- Downloading new App from here for FCC Mode.
Nothing works, people say it's my tablet but i am not convinced because it worked fine and fantastic for three months, unless it's somesetting i'm overlooking?
Can any one help at all with this??
I really don't want to spend another 2oo+ on a tablet if it's not the issue, i tried two more samsung mobile phones and no good either.How ever i did manage to get video feed back but 30seconds in to the flight i get a black screen, it normally comes on before take off then goes out.
