Hi

White XZU user here, on firmware 532

Been having a lot of issues with Fake Hang / Screen of Death, even with the Optimised Backlight ticked

A few symptoms that I have noticed that triggers the Fake Hang / Screen of Death:
1) Whenever I change the Display settings (does not matter which Display settings)
2) After intensive gaming (especially with Real Racing 3), movie or Youtube-ing, that gets the CPU / GPU / battery very hot
Noticed that the XZU would totally hang after a few hours cooldown period (about 4 to 5 hours after situation 1 and 2 described above)

Any ways that you guys can recommend on how to resolve this issue ?
Any help is much appreciated !

Have done a lot of background reading with Android SOD issues, which a lot of people claims is coming from Android deep-sleep mode.
Have tried a lot of things with my XZU, including a CPU keep-awake app (Wake My Android Pro) to prevent the XZU from deep sleep.
It works, until situation 1 and 2 is triggered, which totally defeats the whole multimedia experience of the XZU.
To prevent the Fake Hang / SOD, I constantly had to restart the XZU after the gaming / youtube sessions, which surprisingly helps to prevent Fake Hang / SOD

The XZU is a superbly brilliant device !
Only hope that Sony upcoming firmware updates (if any) can resolve this major stability issue...

Haha...water / ice cooldown...good joke !

The cooldown period is because I need to rest (rather than the XZU) after the gaming sessions..haha !

thatisazam, thx for the advice.
I am using Lux Auto Brightness (free version) for the last 2 weeks, to prevent myself from touching the Display settings.
Same results, fake hang or SOD after the gaming sessions

I was wondering...how does the Lux app prevent SOD ?
Is the SOD caused by the proximity sensor ?
I read that previous Xperia Z issues were caused by Sony using different type of screens from different vendors...probably driver compatabilty issues ?

Anyone can pinpoint what causes the XZU to hang / SOD ?

Thx thatisazam and benny888 for sharing your experiences on the XZU.
It does sounds like it's a "fix-able" firmware issue then...hopefully

Non-LTE HK 532 firmware works without issues...hmm...definitely worth a try then

What country / firmware version are you guys using now (without fake hang) ?

Hi,

XZU C6802 HSDPA user here

After all my previous issues with 14.1.B.1.532, with SOD and Fake Hang, software hangs, looks like all my issues are solved with the new firmware, 14.1.B.2.257 (which can be installed directly thru Sony PCC)

Have been running FW 257 for 2 days without any hiccups at all !
No funny reboots, no hang, no SOD, no anything to complain at all !
Just plain stable, even after extensive gaming, youtube-ing, surfing.
Finally !!!

1) Have been using Lux Dash Lite to control the screen brightness.
(not able to comment on the system default auto system brighness)

2) Ya, agree that X-Reality engine is over-sharpening both photos and videos. Depends on invididual preference, either you like or don't like. From my limited testing, if you play 720p or 1080p stuff, X-Reality engine effects are quite pleasing. If you play videos with less resolution, the X-Reality engine does over-compensate

Cheers !

Hi,

Agree with trellva...if it ain't broke, don't fix it

For my case, I have tremendous issues with firmware 1.510 and 1.532, including fake hang, SOD, random reboots, software hang, random crashes of Xperia Home that needs phone reboots almost every day.

Firmware 2.257 seems to have solved all of that.
Thank goodness.
I was beginning to think that I had a big huge lemon on my hands..haha

X-Reality at firmware 2.257 seems to be "milder", with less sharpening, and with less halo effects (caused by over-sharpening).
To me, seems to be quite a pleasing effect on HD media (720p and 1080p).
Just my 2 cents...

Cheers !
