Lock button keeps triggering camera - Xiaomi Mi A1 Questions & Answers

Whenever I go to press the lock button, it keeps triggering the camera, same for if I go to unlock it. I have to cancel the camera and then go again and it will lock.
Running LineageOS

Hi, there is a gesture to launch camera when you click power button twice, its even in stock android, isnt your button stuck somehow?

It doesnt appear to be stuck, though it does happen about 75% of the time, so I guess theres a chance it is. Is it possible to turn that gesture off?

Not sure how in LineageOS, but in stock Oreo it is in "About phone" in settings.

Lock/Unlock Issue

Anyone experienced this? I'm using the imprint to unlock my 6P. Then after some time while pressing the power button, it supposedly locks the phone. Yes the screen turns black as it should be, but I was expecting that after I unlock it, with the power button, the password does not prompt. Anyone?

Check under lock settings whether, "lock screen immediately" (on press of the power button) option has been selected. If it is set to lock after some time, the phone will be unlocked and hence it will open up if you press the power button without a password prompt.
Here's my current settings. Will try the one you gave.

Ok, seems like your lock immediately option is selected. Do you have the smart lock feature turned on? otherwise, you shouldn't be having this issue.

Seems Lock immediately option to 5 seconds solved my issue. I never turned on my Smart Lock feature. Thanks mate.
Cool that you've solved it. You're welcome!

I had the same issue and it comes back after a while. The only way to solve it is by restarting the phone.
Its back. I'm finding it very annoying now.

I haven't experienced this in a while. I disabled "Power button instantly locks" and it never occurred again.

Double-tap to wake works when button showing; Anker Powerline good 4 fast-charging

Two observations that you might find helpful/interesting:
When using AOD, you can always press firmly where the home button is to get to your homescreen or security, regardless of whether the home button is showing or not. But, you can lightly double-tap to wake the phone *only* when the home button is showing. Interesting.
I purchased these Anker cables and they work great for fast-charging. Same mA showing on Ampere as the stock cable. https://www.amazon.com/gp/product/B01A6F8IUM/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
You can long press where the button would be on a fully blacked out screen with aod off too and screen comes on

I read that somewhere else too, but it doesn't work on mine (Verizon).

I'm pretty sure you have to enable this in the settings 1st.

I'm using Verizon and works fine for myself.
Go to Settings -> Display -> Navigation Bar and turn on the Unlock with home button option

Yea, but that option says "Hard press the Home button while the screen is off to skip the Lock screen."
The person above said "long press" when the screen is off. I see no option for that anywhere.
Also, even if that option is turned to "off," you can *still* hard press the home button any time AOD is on.

I'm pretty sure that's what they meant. Could be wrong, I haven't seen anything about a long press.

Mine took the hard or long press option from the beginning. I don't recall changing anything in the settings but I do find that if I'm not pressing in just the right place, some times it won't wake up.

Power button seems to be 'kinda' working

Hey guys, I have a problem with my power button, seems like it's working but at the same time it's like stuck, so I don't know, if I press the power button just for a bit, it restarts and goes on a loop just because of that, but If I don't press it, everything works fine.
What should I do?

Go to a service centre and get it checked

Sorry to hear that. You could use the fingerprint sensor wake option, and double-tab home or empty areas of nav bar for screen off, I think Lineage OS has both of those. Not sure that's a complete solution though.
I was put off by motorola's locked bootloader in 2012 with a Droid X2, then it's mechanical "Back" button failed, making the phone useless. Being so cheap now and having changed its bootloader policy, I decided to give Moto another go. But I still don't trust the buttons, I want to limit their use as much as possible, using fps wake and double-tab home to sleep.

Yeah, I'm doing that atm but eventually I'll need that button, what if I want to take screenshots or something?
A friend who's a technician will check my phone to see if it can be fixed, hope so..

Anyone got power button issue?

Yes so i visited service center and they flashed nougat and tried to convince me its software issue
Yup same here. Its been going on for 3-4 days and is really annoying me. I think there's something wrong with the button

I had the same issue. It was due to an option "double tap power button" to wake up camera app (I have activated it in nougat) that wasn't present in oreo. I donwgraded to Nougat with a custom rom and no more problem, it was a software issue. It was very annoying, I have used Nova launcher and the option double tap to sleep in order to not use the button.
For me it was an issue with Oreo due to a dirty flash upgrade.

Oreo also have that option(search 'camera" in settings), but on single press it opens camera, that's the problem
Happens sometimes, the physical buttons are pretty bad, they get so squishy after some time. Just disable the double tap for camera, or just return it, it's probably still in warranty and it's acting faulty...

Yes that's the problem because when the gesture is activated before the upgrade it's impossible to desactivate it.
The problem disappears with the downgrade.
For me it wasn't a hardware issue, it was a software issue due to a mismatch between nougat and oreo gesture for activating camera with the power button.
No problem with my power button now and I will never activate this gesture again!!!! :laugh:

Still don't you feel uncomfortable? That you got defective power button?

No more problem with the button. It works perfectly now. I've never had a defective button, for me it was a software issue solved by a downgrade.
I'm agree with the sevice center who tried to convice you. It has happened to me exactly the same situation that you describe and it's solved now.
I've the same issue. Discovered it with Oreo January and it is still present in Orea February Update.
Its definitely a hardware issue
The people saying that the problem was fixed after they disabled the gesture fail to understand that the fault in the gesture is the external manifestation of a larger problem which resides in the power button hardware. The only sustainable solution to this issue, involves root and/or custom roms. If you want to know more, reply to this quote.
PS: The service centres also tried to convince me that it is a software issue, and flash nougat over my los15.1.

The power button on this phone is a little bit flimsy. Too many phones have this issue and the only workaround is to disable a camera shortcut as offered earlier.
The service center fixed same problem for me by replacing one part. You can replace it by yourself, if you brave enough: https://aliexpress.com/item/for-Xia...Switch-Flex-Cable-for-Xiaomi/32848157799.html
Disassembly video. It's pretty easy.
https://www.youtube.com/watch?v=kXo-7CZzpGM
its a hardware issue, the power button is flimsy, i believe its more because of the button themselves then the button circuits as mentioned in the post above.
I thought it is hardware issue but then i realise that volume buttons are also having something same issue and works multiple times pressed once or somtimes volume decrease but no volume pannel.
So, the only way to fix I need to disassembly the phone? Service Center will not fix it?
Thanks

Locked Phone : Camera Quick Access > Black Screen

Hi there,
I dont really know when it started, but when I am trying to quick access the camera via tapping the powerbutton twice while the phone is locked, the camera app pops up but the screen stays black. Hitting the HomeButton and the powerbutton twice again lets the camera app pop up again, this time showing a picture.
Sometimes it even works like it should on the first time, but most of the time it doesnt. Anyone else having this behavior?
Any recommendations? Running entirely on current stock firmware.
Thank you and best regards,
joha

I've had this happen once maybe twice, the camera doesn't seem to wake just the app so you have the app showing but no image from the camera. Screen lock is set tell use pin on my phone. I'd guess it's a bug.
Could try turning the lock screen off see if it still happens.
I can confirm this behavior. But I cannot reproduce it systematically. Sometimes it works sometime not.
