Hi

I recently update my Z3 D6653 to Lollipop 5.0.2. I love the new concept but I found there is a problem. My 3G/4G(LTE) is not working properly. The signal is very weak and I sometimes lose connection. Never really happen on KitKat 4.4.4. Is there anyway to solve this problem?

Don't let the bars fool you @HZcyber

Settings > about phone > status > signal strength > what do you see?

This is something you should contact your carrier/network about, as it could be a network coverage issue.

My signal strenght is -93dbm 10 asu. I tried my sims card of Xiaomi Redmi. 4G signal still working and its full bar. I don't think its my SIMS. Could be the new firmware causing this problem?
