Z5 crash issue

[Katm]

I received my z5 today and have set it up but it keeps going blank and the light flashes red and then it restarts, has anyone else had this issue or is the phone faulty? Thanks

Same issue after update... My Z5 is brand new has only 10 minutes of use and Companion didn't solve the problem. I hope I'll be happy of the Xperia Care service.

I have the same issue with my Z5 Copact. It£s crashing in a very random way, mostly just by laying on the desk. Screen activates and the phone reboots. There is no real pattern to reproduce this problem. Just let the phone sleep on your desk. This is really annoying. I hope Sony can give some feedback on that issue.

I have the exact same problem with my Z5 Compact. I've seen it crash (reboot) several times just laying on the desk in front of me.

I live in Sweden and bought my phone from the UK (Clove).

Is there a log we can look at to get a hint of what's causing the crash/reboot?

Same here, Z5 compact one month old. Sometimes it restarts with the red led without being doing anything.

Yesterday it decided not to read the SIM, had to format.

This needs a fix soon, it's a 600 euros phone

Even to me Z5 continues to crash and reboot continuously and does not read the sim. Bought a little over a month ago ...

Anche a me lo Z5 continua a bloccarsi e riavviare in modo continuo e non legge la sim. Comprato poco piu' di un mese fa ...

I solved by restoring the factory setting, it was probably a virus ...

Ho risolto con il ripristino configurazione di fabbrica, probabilmente era un virus...

Same problem ... only been using the phone out of the box for 3 hours !

It's now crashed at least 10 times !

Same problem here with my z5. The factory reset does not solve it. Is there a fix for this?

Hi,

are there any updates on this? I contacted sony support but the only told me I should enable safe mode and test it 24 hrs. The Problem is, that the freeze appears randomly and sometimes two days all is good and then it comes back.

Hi again,

just wanted to give you an update: my Z5 is running without any crashing since two weeks.

This is all I did so far:

Power button+vol up - no help

Repaired the OS with companion - no help.

Then I mailed the service and they told me to run the phone in safe mode. In safe mode it did not crash for 4-5 days straight. After going back to normal mode, it crashed again. The support said that could mean that some third party app causes the crash. They also asked me to test the phone it without the SIM card and without SD card. So I deleted as much apps as I could (except Whatsapp and Spotify) and also removed the SD card and had no crash for one week (SIM card was plugged in all time). Then I formatted the SD card in FAT32 with my PC, put it in the phone and deleted and formatted the card with the phone one more time. Then I copied all the images and videos and stuff from the backup I made from the SD. I also reinstalled some more apps I have usually installed. Today it is another week without crashing.

So either the SD card was damaged and caused the crash or it was an app I did not reinstall yet (only some other apps left I did not reinstall yet). I will try to install all the apps I had when the crash came up and see if it crashes again but this will take some time, as I only can install one app and wait a couple of days to see if it has an impact.

So if you still have this issue, you might want to format your SD card and uninstall as much as third party apps you don't necessarily need and see how it works.

I will give you an update if I the issue comes up again with a certain app.

Best, Arv
