Phone Clock resets after Reboot. 7.0

DarkEyE — Tue, 06 Dec 2016 22:27:55 GMT

When i restart my Xperia XZ with 7.0, the Clock resets to March 30 1970 3:30 PM. When its online it corrects Date and Time.
Why Clock and Date resets itself at reboot?

Does your phone has a taskiller or antivirus? does it has a SIM card?

No Taskiller or antivirus.
Yes SIM Card.

Hi @DarkEyE,

This is very strange. Does it do the same thing if you start the phone in safe mode?

I have the same problem with Android 7.0 on my Sony Xperia XZ.

Model: F8331
Nougat version: 39.2.A.0.327

With Android 6.01 I could switch the smartphone off and on again without the clock was reset.

Since I have carried out the update on nougat, the clock is reset when I turn the smartphone off and on.

Is there a way to fix the problem.

PS. The safe mode I have not yet tested.
Also, I have not reset the smartphone to factory settings.

Mine did once. Only noticed because WhatsApp wasn't working due to incorrect time and date

Try backing up your phone and running a software repair using Xperia Companion.

Has anybody tested the Companion Software Repair? Does it solve the problem?

Same issue. Clock resets to some date in March and WhatsApp says there's an invalid date. Only when the phone syncs to cellular network time, then everything is corrected. WTH Sony!

Yes, same in Safe Mode.
The System Time is wrong, no way to change it for me.

Re: Phone Clock resets after Reboot. 7.0

DarkEyE — Sun, 11 Dec 2016 19:09:49 GMT

Btw. The System time at 1970 is also ticking up. Its already 4.April there. 😉

I found a workaround for this Problem.
In Settings, Screen Security under PIN I deactivated pin after restart, and everything is alright, just scroll down answered "No Thanks" .

But if i reactivate it the time problem reappeared.

Believe its a BUG in Nougat!

@darkeye This works, but hopefully doesn't compromise on safety of the device?

Just to reiterate what DarkEye has said so far :

1. Yes, after updating to 7.0 the clock resets to some strange dates, was 01 January 1970, now lately to 01 February 1970. So seems to be increasing over time.

2. No, Safe mode makes no difference.

3. No, I cannot test Repair because it does not work (another issue I will have to ask about).

4. Not asking for the Security check on restart (whichever preferred method you choose) does fix the date problem. I don't see this as a compromise as this is a new feature not there before, meaning all old software works fine without it, it just seemed like a nice addition.

Anyway, thanks DarkEye for figuring out the problem

Thanks Hemloc for putting all research about this Bug together. Thats finally all. Point 3. Software repair im not willed to do. I dont believe it will fix this Problem. Because People from Concept for Xperia X have the same issue if they check the clock when they go to emergency call while booting up. Android 7.0 have this Bug also there. 😉

Xperia XZ Time Adjust itself

RiaanK — Thu, 15 Dec 2016 04:11:09 GMT

The time next to battery icon, in the top, right corner was different to the time widget on my home screen.

When I restarted my phone both clocks adjusted to the same time again.

@RiaanK

This issue only happened today, I updated to Android Nougat yesterday.

Point Nr. 4: Not asking for the Security check on restart (whichever preferred method you choose) does fix the date problem. But on cost of security.
But its just a workaround.

Battery is even better. So not here.
