Continuous Restart and Optimizing Apps

vif — Sun, 02 Aug 2015 19:37:15 GMT

Officially updated to Android Lollipop 5.1.1 last week.

Been in good condition until I restarted the phone today.

Now, whenever it's powered up, it optimizes apps, and restarts after optimizing is finished, without reaching lockscreen. I leave it like that for 3 hours hoping it will solve itself, but it just keeps on restarting and optimizing repeatedly.

Have to switch off by the button beside the sim card slot.

Tried to fix it with SonyPC Companion but it's not detected when connected to laptop.

Your help is truly appreciated.

@alexdon

Thanks for fast reply.

Seraj's problem is quite similar with mine but mine doesn't even load lockscreen. Also SonyPC Companion or my laptoop cannot detect it.

Performing a software repair using PC Companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 80% battery.

Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device).

Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable. If PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).

My phone just shuts off randomly; there is no rhyme or reason as to when it decides to stop.

Battery state is usually in the 80%+ range so it's not a case of low battery. In addition, when I reboot the phone to get it to come back on it will not reboot UNLESS it is hooked up to external power. If it is running just on battery power I'll get the sony logo and then the android logo will show on the screen but it will never get past that point on battery power alone. It will just shut off again.

When it does reboot on external power it optimizes the apps EVERY time. It will also show that it is optimizing 270 apps. I don't think if I even have that much of the apps.

When the phone does reboot it loses my WIFI connection information and I have to manually enter that password in each time.

If I manually reboot the phone I get the ANDROID logo and then it goes to the main screen as it should.

Also when I'm calling someone or I'm sending a text message to someone, signals of my network are lost every other time.

Please help!

Thanks

I am using xperia zl. When I was using it, it suddenly turned off and did not restarted again. On external power supply, it started and started doing optimising apps. I made factory reset and also tapped nova button situated near the sim.

Now my phone has stopped optimising apps but a new problem has started.

It is starting only using external power. It remains swithed on if screen is of. If I turn on the dispay, it gets turn off in around 1-2 minutes of usage.

When I got to service centre for software repair, they told to do on my own risk that the phone can become dead.

Please help me what I can do. Your support will be highly appreciated.

You need to wait. Maybe Sony will fix that some time. I have this problem on Z2 Tablet and Z3 Compact. One Z3C was replaced (for other reason) by SC. I did full factory wipe plus reinstall software through PCC. As soon as I encrypted device problem came back. It is related to 5.1.1 builds. Happen most often if SD card is also encrypted but it is not mandatory. I had around 50% error ratio without SD card at all.

Any way to solve this without clear any data?

Or allow us to back up data first?

No time to back up anything.

Hi,

I was wondering if anyone could help me.

My phone died the other day so I charged it up to 100% and then turned it on. As normal, a screen appeared saying optimising app -- of 205. When this finished my phone began to turn on with the usual screens however went straight back to optimising apps 1 of 205.

I left my phone for a few hours to see if it would sort itself out and it ne er it just died again.

I have tried;

'holding down the Power and Volume up buttons together until you feel three vibrations. Now use the press and hold the Powerbutton to start it up as normal' this method.

'try popping open the side panel and find the tiny yellow button next to the SIM card. Use the tip of a pen to press and hold it down until you feel a series of vibrations. Press and hold the Power button, and you should feel a vibration that signals it is starting up' this method.

AND I have connected it to the computer to try and fix with PC COMPANION and it wont recognise on the computer.

I have tried to do a hard factory reset and nothing happens.

PLEASE can someone help me.

I also faced this problem.

My phone provider told me best to do complete reinstall of the phone, organising all apps again and maybe get rid of essential info.

Originally I used my phone for work and it needed to be encrypted and provided with some protection pattern or number.

I think I faced the issue when I didn't use the phone for work anymore.

The encryption was removed, but I think I did keep the pattern for access.

I decided to remove the pattern protection, do a restart where the problem was solved (only less than a minute the hanglock with activity indicator pictogram) and then the normal startup sequence.

Then I installed the pattern again and did a restart and the Optimizing Apps still did not happen again 😉 !

I have the same problem as Anum. Since one week ago my Xperia Z switches off alone when I'm working with it and when I restart it it starts to optimized the android applications. Usually it doesn't finished with this optimization and it crashes again unless I have it plugged to the charger. If I have it plugged it takes ages to optimize all the applications. I also noticed that I lost signal very often. It looks like it only happens when battery is lower than 80%. Anybody found some solution? Does the repair through PC Companion work? I see a lot of people having similar problems in the last months.

I have this issue and have gone through the 'solution' provided, reset the phone 3 times now, it wont even clenly get through the initial startup after reset before it turns off again. It seems the phone wont even last and hour before turning off now, its practucally unusable. Are there any other fixes out there or is this a hardware issue? Any thoughts much apreciated.

wildnico — Mon, 23 May 2016 21:01:27 GMT

same here...

It started 1 month ago with strange battery drop and my phone dying unexpectedly... "Repaired" it through PC companion, didn't change anything really. Also reboot to factory settings didn't help. After that, the "life" of my battery got even smaller... going from 85% to 0%...and when starting back again, claiming 60% or so... until next drop.

Now it just can't stay on for more than 5min if not plugged to power. and when dead it's a pain to turn it on again... loop of booting, android initializing and never reaching the total apps to optimize, etc...

I read lots of similar stuff, and nothing real that seems to work.

I'm sending it back soon to Sony for an official repair, let's see what they will say... It's not even 1y 1/2 old and I'm very mild with my phone, no overuse, no fall, etc...

Don't really know if it can be repaired at this point :s
