"I've encountered a problem of which when I received a call, or make a call out and connected to the recipient, the network gone flat. I have to re-key in my pin code everytime the network is lost. I am using Maxis line and this issue occurs only when I am set to 3G preferred only settings and everything is good when I set my network preference to 2g prefered network.

I have updated to 4.7.12 today with the hope that the issue might be rectify but it was not.


Device: Xiaomi Mi3 (WCDMA)
Firmware: Dev Rom 4.7.12
Network: Maxis

Dev team please look into this issue or else it basically means that the phone can only use 2G if this problem is not solved. "

Anyone encounter this issue?
