A50 that Im using has an issue of automatic lock and flick screen.
I have found the exact reason for the issue.
It happens (automatic lock and flick screen) while switching from LTE to 2G.
If I'm at a low signal place the screen starts to flick and locks automatically due to switching between networks. Check the video guys and developers please fix it is so annoying. @Samsung #samsung
And the support team never notice the thing only the bot reply again and again. For their bug error why do I want to reach the service center and give my primary mobile dor service.
And this happens after the one ui update.
Possible fix right now is by switching 3g only mode or by installing force LTE only app from playstore And select LTE ONLY. But the issue is receiving calls and msgs because most msgs are delevered by 2g and calls can be recieved if the network provider provides VoLte.
