XZ Premium constant freezing and lag after.

[Sebjs]

Hi just got my phone 2 weeks ago.

After I charged it over night just at the start of the second week the phone failed to unlock after pressing different buttons. 

Finally it unlocked but was incredibly laggy. Now I'm finding at random times of the day when I haven't been operating the phone it lags really badly and fails to unlock again. 

Couldn't even type into the keyboard with out the phone freezing up and then releasing its self after about 10 seconds. 

Finding I'm having to restart the phone every time this happens. 

Has any body else had this issue happen to them and is there a way to fix this? 

Thanks.

Hi @Sebjs, welcome to the community. I am sorry to hear about this

How soon after restarting the phone do you notice this issue?

[Sebjs]

It's a bit all over the place. Notice it the most after charging the device, but this morning just did it as I woke up. Phone hadn't been used since 11:00 the night before didn't go onto charge, picked it up at about 10 to go through messages and reply and started playing up again.

Try starting your phone in safe mode and see if it does the same thing. This is so we can test to see if the issue is caused by third party apps or not.

Thanks will check it tonight when I get home. 

Will update. 

Thanks!

I'm experiencing the same issue, had done a factory reset and only installed a couple of apps to test and still persists. Phone will seriously lag at least once a day and force me to reboot.

Will also lag on some web pages causing me to close and restart the app. Only 2 weeks old also. 

Build #45.0.A.1.229. Australia via Optus.

Exact same problem here (also 45.0.A.1.229).  Phone will become very laggy and unresponsive at completely random times.  Sometimes it returns to normal after about 5 - 10 mins while other times the only solution is to perform a restart.

Installed Simple System Monitor from the app store to see what was going on and when this happens, 1 CPU core is maxed to 100% the entire time.

I'm in Australia, also on Optus.

Edit: If there is any way of seeing apps by CPU usage (I understand Google removed this in 7.0/7.1) we would be able to know for certain what is causing it.

Hi all,

Same problem here. Basically I have 1-3 sudden lags with my phone everyday and I can only reboot it most of the time. I feel like this started to happen right after one update from Sony, but I am not really sure yet.

I got my phone from Sony Hong Kong. Will definitely appreciate any solutions, as I am feeling a bit annoyed about this already.

Thanks a lot!

Yes, I had too encountered this issue on my XZ premium as well.

It would just suddenly start to slow down to a crawl and become extremely unresponsive until you have to do a restart. Sometimes it will just do it when it was just in my pocket without doing anything and when that happens, the phone feels warm.

Frequency of occurence: random, can be within few days/a week
