Sony Xperia Z shut off itself

[Azizi]

Hi,

I've already updated my phone to latest firmware 10.1.1.A.1.253 on 17/5/2013 via Sony companian.I experienced my phone shutdown by itself on 25/5/2013.Even though i pressed power button the phone cannot ON,I made a reset by pressing power button+vol then phone able to switch ON.

May I know why this problem still persist?

Thank you.

Is there any Sony Support guys can answer this?Come on guys

Did you reset your phone after the update? If not, you should give it a try. Let me know the results.

Dear Samuel,

After update the firmware,I did restart the phone.On 27/5/2013,once again my Hp unable to ON during I pressed power button as usual to wake up the screen.

After that, I unmount my sdcard from the phone.I am using 'sandisk SDHC 4' card.Is the 'SDHC' card contribute to this problem?

Kindly need your advice Samuel

thank you.

A restart yes, but I meant a reset. Settings > Backup and reset > Reset. Just make sure you've backed up everything you want to save!

The SD card shouldn't cause any issues. SDHC just stands for Secure Digital High Capacity, which means all SD cards 4-32GB. 4 stands for class 4, which is minimum 4mb/s read/write speed.

I see,I didn't do 'reset' yet since the update.I will do the 'reset' & I will revert to you a.s.a.p. to inform you the result.

thank you Samuel.

Might be some app acting up. Just try to restart the phone and it should work as intended.

remove the SD card and micro SIM card, w/o both cards > restart your phone and try to use without it, the issue might be a faulty SIM card or SD card
