phone shut down automatically after sim insertion

[kira71]

It has started since yesterday

First of all my network kept on going from 0 bars to all the bars.

Then my phone started to turn off even when the charge was 30%

I charged the phone and it showed 100% in about 30 mins.

I unplugged and it switched off again.

I checked the battery status from the service menu and it said health was good

I took off the sim and charged the phone again.

It shut down twice or thrice by itself even after that but started charging properly and worked good till the reinserted the sim today

Pls someone help me

the phone will restart once it detects the simcard has been pulled out or inserted regardless if it is turned on or off,

try to see if the problems persist when you are on safe mode

if it does, try to perform software repair using Xperia Companion
