cannot turn off my phone

[issuer]

Hi everybody, after charging my phone I realised I could not switch it off - neither using the power off button nor using a virtual button on the screen. If I use this virtual button and select power off, the phone just reinitiates.

I have tried repair apps, wiped the cache... to no avail. Even a factory reset did nothing. That is to say, nothing has worked so far.
Besides, when the screen goes black it's complicated to wake it up again unless you use accessibility options (at least that works).

The phone has no other trouble than that, it seems.

Help, please.

Welcome.

Is this a new phone?

 

[fuzzylumpkin]

Also, what phone is it?

You have no idea how hard it is to resist asking "have you tried turning it off and on again" lol

 

[Mr. Lucky]

You don't mention what phone you have, but my phone (Razr+) has an option in Settings > Gestures for ""Press and hold power button" which has a "Hold for Assistant" toggle. If it's switched on, then you'll never see the power menu by pressing the power button; you must follow one of the methods here in that case.

If you have it set so that press & holding the power button activates Assistant but have Assistant disabled, it will act as you describe.

Welcome to Android Central! On newer phones, you may have to press Power and Vol Up together to get the power options.

Welcome to AC!
We love to help but looks like we need more info

Hello everybody, and thanks. It's an Oppo A15, not too new but not too old

What happens if you press Power and Volume Up together -- do you get a power options menu then?

You said you "loaded" your phone... did you install a custom rom? With everything you've tried it sounds like you might have to reflash your stock firmware... especially if you've installed a custom rom that's giving you problems. @mustang7757 would be able to help you with that

Hi, it's not a custom rom, I wish I could use them. I tried one of those some time ago, on a phone I was going to discard and it went definitely crazy.

And yep, I tried pressing volume buttons, down, up, up+down, even while charging, but got nowhere.

The last thing I've tried is an update while being on recovery mode. The update was OK, I even got a pop-up message that said that the phone was in optimal condition. In fact it works fine, but still doesn't go off

 

[J Dubbs]

You know there's lots of folks who never turn their phones off. If you're okay with that you might be able to get a few more years out of it

You could also reflash your stock firmware with mustang's help... that would probably fix the issue.

I know, but can it be dangerous if you never turn the phone off? ie, could it catch fire in some (rare) cases?
Anyway I guess it's better for the battery to turn it off more or less frequently.

Keeping your phone turned on does not make it catch fire, why would it?

I'm not familiar with Oppo devices but XDA Forum has good info

If you press and hold Power for about 15-20 seconds, that should force a shutdown on any Android device. Does that work for you?

No, it didn't. Wish it did

Do you think the Power button is faulty or does it work together with the Volume buttons?
So what did you mean by loaded?
Adding your apps to a factory refreshed phone?

Have you tried the on screen Power button provided via the Accessibility settings?

You would still have a screen wake problem.

Is there a power off in Recovery Mode? I think there's a piece of the puzzle missing or misread here.

A search shows many Oppo / Oppo A15 Power button problems, but that might apply to most phones.

Also can you restart your phone if you let the battery run down?

That should work for any Android device, regardless of the manufacturer -- it's kind of a failsafe measure. This makes me suspect that there's a hardware problem with the Power button itself.

Tried everything, but the problem won't go away

If I use an app or try to turn the phone off in recovery mode - I mean, without using the physical power button, it's the same thing. It just reinitiates
