New update had ruined performance

[D00dlebug]

Since the newest update, my phone has been running really badly. 

Firstly you've changed the top bar to be so blindingly bright ive had to put night mode on all the time to get around it. Dunno what that's all about. 

But mainly this update has killed my phones performance. Everything is now slow and can't keep up. Having more than one app open at once makes the phone visibly chug, and it often can't handle video. It was totally fine right up until the phone updated, and then the problems started.

Obviously I've done all the usual checks and fixes but it's not improving. 

I'd love to know if other people have had this issue, and whether Sony has any ideas on why this is happening or how I can fix it my end, or if they plan to fix this their side.

Thanks.

Agreed. 

The xz3 phone is horrible now, a restart is required every 8 hours or so to remove the worst lag

Before the update it was smooth running for weeks.

Do you know the software build number?  my phone is running ok so I'd like to avoid this update if I can. 

Edit. I see the android 10 update is rolling out,  think I'll give it a miss.

I have experienced exactly the same thing. I was so happy with the phone until now. It is useless now.

Hopefully Sony will fix this soon.

I'm actually a bit surprised how bad my XZ3 (PF42) has become with the Android 10 regarding performance.

For Sony: Try to run Netflix split-screen (or picture-in-picture) and use Chrome at the same time. This was a non-issue before, but now performance can go to a crawl. It's strange that it works quite alright sometimes, and horribly slow sometimes.

Yes, 

for me the phone is not usable anymore. Run Pokemon go and a browser... Laggy crap. Or camera app and any other... Neather the csmera app is working or the other app. The batter performance is not okay anymore (was never fine but now i can use the phone for an hour display on).

The alarm clock does not stop making alarm... Till u deactivate the used alarm time.

It seems we have a buffer overrun now. 

The display light goes dark when it wants to but if u hold ur Finger on the light chip nothing changes... The fingerprint unlock does not works at any time. Means when u lock ur phone for a minute u can put ur Finger at the sensor and nothing happens till u unlock with the Button. Even at i was writing this sentences i had to close my support app i used to visit this forum. Buffer overrun?

Sorry Sony, i allways had a sony but i go to use my galaxy s9 again. Runs much better at moment.

Hey, I have the same with my Xperia XZ3. It was top notch phone, but after the update, it almost has troubles running one single app. Will try to do the repair and reinstall the system completely.

@mantaraycz: Please let us know if that solves the issue.

Same issue here, after the update performance is horrible. Keeping single game in background makes everything super laggy. 

[KrisPalm]

Yes have the same problem, latest update absolutely ruined performance. 

Every little action takes 1-2 seconds longer than before!

Messages , what's up, camera, Android auto, everything just lagg..

Seriously considering switching back to my old iPhone
