Previous update is killing my Xperia Z2

[renneyleslie]

Hi guys

Ever since the update
1. My contacts keep disappearing and reappearing
2. People sometimes don't hear me when I talk to them on the phone, while the mic works fine in other applications
3. Sim card stops being detected randomly by the system

I don't know what is wrong

What you described sounds like a SIM card issue not a phone issue, get a brand new SIM card and report back

I'll try and get a new one then, thanks

If you want to try something else, you could repair the phone with PCC and check again, but the problem seems a faulty SIM card.

Bridge (for Mac)
