Z5 Premium randomly freezes/hangs

[uc0d3r]

Hi All,

New phone, after updating to 6.x version it started to freeze and hang randomly.

Just a freeze then no response from screen then reboot with red light blikning on right side and after that it works for a while normally, when you don't touch it it doesn't hang, but you can delete the file or take a photo or install the app and during randon process it hangs.. 

Tried to wipe the phone - reset to defaults - same issue

Tried to do that again - reset to defaults with full wipe - same issue

Tried to repair software via PC connection - done, same issue appears.

Phone is only a couple a days in my hands - really disguisting experience, any advises ? 

Or best advise would be to make a return and forget about it ? 

Thanks guys in advance.

Okay so the same issue after reseting the phone and repairing it again.

I will just create a ticket and send it to the repair center as defect.

Thanks guys for your support !

Contacted directly Amazon - from where I purchased they agreed to replace the phone for free without any questions or troubleshooting Thanks again everyone for help, enjoy the weekend guys !

Glad to hear you got it replaced. Luckily I got mine through Amazon as well so they didn;t ask any questions and just got me a new one. I read some horrible stories of people who bought it directly from Sony or network operator and never get it fixed or replaced (i.e. Sony refused to acknowledeg it as a fault).

Hopefully new one will work fine. I had to replace mine FOUR times befoe I got a properly working unit without any problems.

Four times is really too much.. Hope that it will start working fine after first replacement  

And regarding horrible stories, well it's really sad when the issue starts immediately with a new phone and vendor can't help you for free so basically you are throwing away your money  

This phone was a gift to my wife, previously she had a Z1 Compact and she was happy with it, but by some reason screen has cracked - it wasn't dropped or something it was in the case, and in one day she noticed that top of the screen (touchpad) is not working.. there are some months warraty left but don't think that they would fix this for free.. so will leave it probably just for a navigation or something

So here how it was

I have sent this phone to amazon back - they have tried to repair it.

Have waited for one week - it came back with a note - that phone has passed all the tests and it works fine.

Great.. turning on the phone, installing apps, enabled GPS or something and what's that.. it has hanged and rebooted again.

Once more I have done the software repair, removed sim,sd - after playing with a phone in this mode issue has appeared again.. 

Wrote an email to amazon that I want to get replacement not the repair, they have sent the replacement.

Yesterday I have received new phone it works like a charm, didn't saw any reboots + it's not overheating so much as previous phone had. 

So problem is finnaly solved, thank you guys who has participated in this thread !

I have had my phone for 6 months before it started to freeze and reboot randomly. So i had several updates. So the problem must be with one of the updates? it cannot be just a hardware problem. The phone does get hot. But had that with more sony xperia models. But they never froze and rebooted. Or this is a safety precaution in the software, so the pgone doesn't get too hot maybe??
