Encrypted CM11 Z1, constant problems, how to decrypt? - Xperia Z1 Q&A, Help & Troubleshooting

I encrypted Z1 last night now I have constant problems with it. After being locked for 30 min or so, even 5 sometimes, it just won't wake up, stays black, and needs a hard reset.
I figure I cannot decrypt and have to... somehow, re-image it with a pure cm11? Or?
While on and running, is there a way to back up all apps so that when re-installed, I could just restore all apps and their settings? Multiple SSO etc, don't want to lose these settings.

[Q] CM10 Notification Sounds Erratic

For the past few CM10 nightlies (since at least ~10/15) I've noticed that notification sounds only play when the screen active. If the phone is locked and the screen is off, it will vibrate but make no noises. I've tried restoring to previous backups and have had no luck. Also have tried clearing cache and dalvik.
The phone rings properly when receiving calls regardless of screen state.
Any ideas what I can try short of completely wiping and starting over?

I don't run CM10 myself but wouldn't flashing a stable version fix your problem?
Also, could be something in your settings.

[Q] Ambient display failure

It worked when I first booted up. After a few hours it quit. I did a factory reset, and the same thing happened. I then went through my running apps and turned them off until none were running except the system apps. Still didn't work.
Anyone else have this happen that can suggest a fix? If I have to reset and install apps one by one, how do I do that, since on signing into Google the apps auto load

To fix auto load, you can change the system setting to not backup apps; it's in Settings > Backup & reset. I thought upon initial Google account sign in you could switch that setting off too, and that prevents the apps from auto-installing. I have backup turned off because on previous devices and versions of Android it was contributing to battery drain.

I did what you suggested, adding single apps and confirming the ambient function worked. Found an app that seemed to be the cause, and upon uninstalling it the ambient function came on line. However, about a half hour later, it stopped working again. Spent over an hour on the phone with Moto, and they figured out that ambient doesn't respond unless the phone has been asleep more than 10 seconds. That seemed to work for me. So I did my 4th reset/install of the day, and again, it worked for a while, even with all my apps (including the one that seemed to be the cause in the first place). And then, it stopped again.
I searched, and one suggestion was that ambient won't work unless you have a locked screen. I usually don't use a lock, but what the hey, I'll try it. Set up a pattern unlock and (wait for it.........).
Nope.
I'm stumped.......
Mine seems to stop displaying the ambient as well. It will display a few times initially and then stops. I don't know if it extends its sleep period after every interval or not. Also seems like if you lift up your phone to look at your ambient notifications, that disables any repeat display too

z3 compact - update to Lollipop trashes the phone

Hi,
I had update the phone to the newest Lollipop update from Sony. At the beginning in the first 2-3 days the phone works wonderfull.Verry snappy and responsive.
But after those first days of joy the problems appeared.
The camera become very laggy. The battery drains in 7-8 hours and the phone is overheating. Even I keep the phone in my pocket, it becomes very hot without touching it.
And if I read something on my RSS feed, in about 5 minutes the battery drains 2-3%
I allready saw many people reported thoes esues and it seems that the only solution is a hard reset to factory default.
Witch I will do, because right now the phone is quite usefull and anoing.
My questions for you are:
1- is there any other method but resetting the phone?
2- how do I backup EVERYTHING from the phone? Contacts I can manage with pcCompanion, but how can I save all aps and their data? Games for instance...I'd like to keep my ingame progress.
I'm new to android comming from 5 years of iphone. On IOS this opertion was really simple due to a full backup on cloud. And after a reset - or switch to a new phone - everything was restored as it was from cloud.
Can I do the same thing on android? I wold prefer using google and cloud.
thanks
Google syncs all of your contacts automatically, so after the phone resets, simply log in to your google account and the contacts will be restored. You can do the same with photos/videos and music using google photos and google music. Google can also remember which apps you had installed and re-install them automatically, but you can't do anything about settings. Those will always have to be re-done manually.

Phone acting super weird 2 day after upgrading to 4.1.6

Start from the beginning. Back a few weeks ago, when 4.1.5 was leaked but not officially announced, I downloaded 4.1.5 and flashed it through TWRP. Then 4.1.6 was released officially right after I've done my upgrading. So I CLEAN FLASHED 4.1.6 again on my phone.
Now the weird part: after 2 days of normal use (no flashing, no new apps installed), I left my phone charging today while went asleep. After I woke up, my phone is at 15% of battery. Although connect to the DASH charger, the phone doesn't charge at all with its LED showing red.
More weird is I can't open the notification center. I can pull the 5 toggles down, but can't open the whole menu.
Plus, notifications don't show up (no toast notification, no icons while in the homepage either).
My access to developer options is also blocked (says "Developer options is not available to this user").
The home button, recent apps button DOESN'T work - no matter if u switch the buttons in settings, or toggle the on-screen soft buttons. Although the "return" button and the fingerprint sensor DOES work.
Root access is still there (using Magisk).
While using TitaniumBackup, the app warns "This device's Android ID has changed". And a few apps have logged themselves out (I guess because of the ID change).
I think I can solve the problem by simply factory reset it. But Questions is : what's going on with my phone?
Its a common, not so common issue. I had exactly that same issue twice on two different fones. My old xperia L and my oneplus one. In my particular case, this was triggered when my settings were automatically restored from my google account (apps auto download, wifi settings, display settings etc.) After a factory reset.
After this, android id "crashes" showing that it has been changed, and statusbar only allows one pull down, along with the others bugs you described.
You should not allow google account to restore your settings (or at least that worked out for me) and restore manually your data. (Especially your display settings).
Hope it helps, i thought i was the only one.

Wow! I can't image someone had the same issue. So i actually re-flashed 4.1.6 and it's working.
But the charging problem persists. I've tried multiple power sources from the room, the kitchen, etc. None seem to be working.
Strangely, I was able to charge the device once a few hours ago at evening. And then it stopped charging again after I got the system working.
Any idea?

Frequent System UI freezing?

Hi Everyone,
It has been going on for roughly a year now, while I'm using my phone it suddenly just freezes entirely. Touchscreen just becomes unresponsive, can't tap on anything, gestures don't work and notification bar can't be pulled down.
Physical buttons does not seem to be affected, even if my screen is totally frozen I can still adjust volume levels and I can lock the phone via the power button. After locking and unlocking my phone, everything goes back to normal, touch responsiveness comes back and starts working as it should till the next hiccup.
It happens frequently, there are times when the screen locks up 2 or 3 times in a 10 minute period window. Every time this happens, I need to lock and unlock my phone and it starts working again.
Also it doesn't seem like a specific application is doing it, it happens when I'm browsing websites via Google Chrome, it happens with Amazon App, Messenger, Google Play Store, even on the Google News feed.
It gets more and more annoying as time goes by and it still hasn't been fixed.
I have been in contact with Google Support in the beginning when it started, but all they suggested is that I should do a Factory Reset (which I did).
Has anyone else experienced this issue or is it just my device doing this?
PS.: My phone is fully stock, hasn't been messed around.
Any physical damage to the device? & Have you tried checking if the issue occurs in safe mode too? If it is caused by a 3rd party or background app it wont replicate in safe mode.
Scan with Malwarebytes.
Try clearing system cache.
Try safe mode and a hard reboot.
That qualifies for erratic behavior and may be the only sign of a virus or trojan you'll see... at first.
Either way you could be headed for a boot loop.
Regardless even if Malwarebytes finds nothing it's factory reset time. Nuke it; a trojan can do a lot of damage to you in a short amount of time.
After the reload change your Google password.
Before you load -anything- make sure the issue is gone!
If it persists it's either a firmware or more likely a hardware failure.
