Encrypted Z3 compact tablet/phone, but no password needed to log on

probedb — Thu, 28 Jan 2016 22:17:29 GMT

I see someone already posted this last year for a Z2.

Swirling security icon on boot but never asks for a password.

Thoughts? I have the latest firmware and please don't tell me to reset it back to factory settings, I never had to do this when I had a Nexus 4, 5 or 7 when firmware updates happened.

Love my Z3 Compacts but has some weirdness with encryption.

Encryption problems, won't accept password?

probedb — Fri, 04 Sep 2015 09:31:17 GMT

My tablet is encrypted and for the most part works fine, accepts my password on startup and is OK.

However every so often, like this morning, it won't accept the password so starts counting down to device reset. Sometimes powering down and powering back on works but today it hasn't.

Has anyone ever had this problem?

Currently I'm wondering whether it has issues when the battery is lower than maybe 30%? I'm leaving it charging to see if it will accept it once it's charged.

On 5.1.1.

Thanks in advance,

Paul.

@probedb

Are you using any antivirus app that might be acting up?

No, this is Android itself, at this point no apps have launched, not even the main OS. This is full device encryption.

It would appear the problem is power. I left it charging and with 100% charge it accepted my password.

I wonder if this is a device or an Android problem.

You could backup everything and then repair the tablet with PCC and check again

PC Companion (PCC)

Bridge (for Mac)

Thanks for the suggestion, I might give it a try, maybe I should just charge my tablet more often So far it's been an ideal tablet, also have the Z3 Compact phone.

Keep us updated.

An update, this morning switched the tablet on (battery at over 75%) and it appeared to accept the password. But it had rebooted and asked for the password again, this time refusing to accept it. I then kept getting 'Unfortunately settings has crashed' messages and my password was not accepted.

Rebooted, same again, not accepting password.

Switched off, plugged in power adaptor, switched on and it accepted the password.

The odd thing is that it did the 'Optimising application X of Y' as if the OS had been upgraded yet nothing has been updated?

That sounds very strange.

The battery level should not be able to cause something like this and i can't replicate this issue here.

We are aware of the second issue though where it's optimizing the apps on reboot. Do you have an external SD card and if so, do you see the first issue if you remove it?

Hi, yes, very strange 😕

It didn't do it before the 5.1.1 update that I remember. No external SD card in the device. I have no problems with my Z3 Compact phone.

I think tomorrow when I have time I'll try a full factory reset and see what happens.

As an aside, if you press the End key in the rich text editor it's inserting a hash instead of moving the cursor to the end of the line.

Yes, i think that might be a good idea. But if possible, do the software repair from PC Companion so that the firmware is reinstalled as you might have an issue there in your device.

Which browser are you using? If i press end i'm taken to the end of the current line.

So no idea what's going on, it's worked fine with 20% charge and switching on. I guess the joys of software/hardware!

Re: Encryption problems, won't accept password?

Rickard — Fri, 18 Sep 2015 06:36:47 GMT

I suspect the issue is caused by something else than the battery level. Did you try to repair the software using PC Companion? There might be an issue with the software installation in your device.

Re: Encryption problems, won't accept password?

probedb — Tue, 22 Sep 2015 21:03:17 GMT

Yep, I let it charge to 100% and had the same issue, reset it and it accepted the password.

At some point I'll try the software and reset.

Yes, I have the same problem with encryption. No encryption is not a problem

probedb — Fri, 06 Nov 2015 13:35:25 GMT

I've not had it for a while, however with an update I got through the other night, every time I turn it on it's going through the 'optimising apps' phase. My phone doesn't have any of these issues.

Re: Encryption problems, won't accept password?

PetCZ — Tue, 10 Nov 2015 06:40:24 GMT

I also wrote 'optimising apps' and then could not enter a password

@probedb

have you added a trusted location?

Re: Encrypted Z3 compact tablet/phone, but no password needed to log on

probedb — Thu, 28 Jan 2016 22:34:51 GMT

I doubt it, I have no idea what a trusted location is.
