Can't remove T2 Ultra screen lock PIN

[TracyF]

Hi everyone,

I love my T2-- except for this problem:

I added a PIN, temporarily I thought, and then have no way to remove it. Under security-- "clear credentials" is grayed out. Under the PIN area, I'm asked to enter it, but there's no where to undo it?

Is there any way to fix this short of a reset? It seems a bit drastic & this issue has been around for a ong time, as I Googled it for answers...why hasn't it been fixed?

Thanks for your assistance!

Currently on 19.0.D.0.253

Hi TracyF,

Welcome to the community!

To confirm you have not forgotten your PIN, you just want to remove it and change it to the 'Swipe' method?

Correct.

I had an appointment in a gov't building where I had to leave behind my mobile. Being the good little sceptic that I am, I first put a lock screen PIN. Afterwards, I went to remove it & couldn't.

Right now, I'm backing up the T2 (PC Companion) & want to upgrade it to whatever is the newest Android. I just wanted that stupid PIN gone before I do. I don't really like a PIN on my phone.

Lastly, anything I should know before updating? And what's the best way to do so?

Cheers!

@TracyF Before you repair, could you tell us why you can't remove it? There is no way for you to remember it or simply slide or none is not available?

[TracyF]

I know my pin, I just want it off. In the settings, I have no option to remove it (as other directions have said). I go into the pin settings, it asks for my current pin (which I know works as it unlocks my screen) & it just loops there, over & over...

So, I looked up repair online, but since I'm behind in the OS anyway, I decided to backup & install the newest Android for this mobile (T2 Ultra Dual-SIM).

@TracyF

Just wondering, did you encrypted the phone? if you did that's the reason you can't remove the pin code. 

[TracyF]

No, I didn't encrypt the mobile.

This is a well-known issue on Sony mobiles, apparently. One person suggested that only a factory reset would fix it?

If I upgrade to the newest OS, will that stupid PIN still be required if I import the backup I made?

This is so aggravating! All I want is to NOT have to enter my frigging PIN & there's nothing I can do??

Anyone?

Thank you for your help or ideas.

I have a T2 Ultra but I can't recreate the issue, I'll keep checking
