A52 cellular network problem.

[aslamsujaa]

every few minutes network cut and return 4g to 3g, 3g to 4g. battery drain fast. 

I have done everything and reset network setting. nothing changed.

Do u get calls or texts when it changes from 3G to 4G or is there a signal drop when it happens?

It's the problem with your signal level and not a considerable issue with your device itself.
