[Q] No signal and needs to reboot the phone
Hi Guys, I have a E988 HK version 10D Stock Rom. I found the signal is not stable at all.
As my mobile carrier does not support 4G, so have seleted the network to 2G/WGCDMA.
I found the phone lost signal completely and then it has an error saying sim invalid, but when I reboot the phone, the signal became good again. This is very painfu as I needed to reboot my phone a few times a day.
Can someone give me an idea please? Thanks.
