Have had my phone for months, but suddenly the power button stopped working properly.
It's stuck in a recessed state and has no "click" to it anymore. It's very hard to press, but if I use my nail and push it in the power button does feature, but again no "click" or response to the button press. More than anything I am worried about it becoming permanently broken, likely leaving the phone unusable.
Due to some location/warranty issues, I think getting the phone replaced (for now) is near-impossible/not really feasible.
I am in New Zealand where Google doesn't have any presence and I am unsure if any local "phone repair" shops might even be able to fix it - especially if any replacement parts are needed.
Does anyone have any thoughts or advice to try and fix the button myself? It was in a case since day 1 and I cannot recall any single time a drop would have happened or some dirt/sand/etc. would have gotten in and stuck. I used a "rocket blower" I use for my camera gear to just blow the button area, but no change.
Happy to provide more info if needed... all help is more than greatly appreciated!!!

All I can recommend is a soft key power button...on statusbar or navbar. You need to be rooted.
I use Fingerprint Quick Action app but same deal (root I think). With it I assigned double tap to fingerprint reader to turn off the display.
As for power button replacement, iFixit teardown of the XL doesn't look like an easy DIY thing, with display damage a likely scenario during disassembly. Good luck with that.
It's not a fix but for the moment Nova louncher has great gestures to lock the screen swiping up or down, double tap and more.
I know how this sounds, but try sealing your lips around it and give it a good suck. Like you'll feel that you're sucking air through other gaps in the housing. Popped my button out and it's clicking again. Might only be a temporary fix, but it's been a couple of days without an issue for me. Damn thing has been bugging me for about a month, sometimes getting stuck long enough to hard-reboot the phone. Almost felt like there was some sticky **** under the button.

my xda2s recently experienced a problem which consists of the volume bar keep going up and up making the 'end' noise repeatedly, and if say the volume bar on the side were to be pressed down, it would go down n go up again...
secondly, the power button is not functioning well, it can turn the phone on by clicking it once (as usual) it can turn the backlight on and off by holding it (as usual) but it wont turn off by pressing it once, or anything...
help please, thank you
doesn't happen with any of my 3... sounds like you've got them there problems.
pYroboy,
let me know if you found the resolution. My problems are similar to yours...
Thanks.
doesnt happen to any of my two BA...
try opening up your unit and clean up the contacts.
I did open it, but could not figure out which contact to clean. Power switch is sooooooo freaking small, I did not figure out what I could clean there, it seems that it is 2x4mm in size soldered for good to the board. Same about volume rocker/switch on the side.
How is it possible to clean them??? I could not figure out what could be cleaned there without detaching the switches from the board.
Does anyone sell these parts? Maybe it would be easier (although not easy also because they are so freaking small) to replace them??
Guys, need advice from you... from the ones who fooled around with similar parts...
Thanks.
try an air brush. or a fast evaporating contact cleaner.
just make sure you apply enough pressure not to blow the sensitive parts away.
*just becareful
OK. Thanks. I'll try that. But where do you people get that stuff. Do they sell it in electronics stores, or I need to look someplace else?
I need to do something anyway, because today I can't turn ON. I used timeout of 1 minute on battery power to power it OFF. But not being able to turn the whole thing ON really put me down....
Is there any program to remap Power On/Off button to Recorder or Media Player buttons on the side? They are all 3 the same switches. If it would be possible, I'd get by using one of those buttons.... Just running out of freaking ideas here....
contact cleaners can be found in your local radioshack(i.e. electronics or computer botique/shops).
regarding the power button i think that is hardwired to be the only powerbutton for the unit. sad to say you cant map it to powerup your BA.

Assuming you have the button lock enabled you can wake it up by receiving a phone call, and then disable the button lock and use any button to wake up/turn on the device. This is not the most elegant solution, but if cleaning fails to fix it then it may be your only option.
Initially when pressing the back button on my desire, a large majority of the time, it would register it correctly (i.e. do the operation associated with the back button), irrespective of my finger placement as long as I apply a low amount of pressure.
Now, I find that a lot more key presses on the back button are lost. I have to press much more harder / deeper to improve the chance the keypress registers. This is the second time I've encountered this and the third hardware fault I've had:
Fault #1: headphone jack not working, music continues to play through speaker (repaired)
Fault #2: back button doesn't always register key presses (repaired)
Fault #3: back button doesn't always register key presses (going to have to be repaired again, sigh).
I've searched the forums but haven't found anyone else mentioning this problem. Has anyone else experienced this issue at all? Or have I got crummy luck and gotten an HTC Lemon?
I have the exact same thing. Only started recently though. It takes a hard press sometimes, and other times if I press hard it's like a double button push.
You aren't alone. Lol
Cheers rolfd. Least I know I don't have the "touch of death".
It's definitely fixable cos I've handed it in for repair and it's come back working. My concern is more if it continues to re-occur. Guess I'll have to wait and see...
You are not alone about this problem:

Both mine Menu and Back is not working properly. Got send it in for service and still havent get it back yet.
*Update* My phone got repaired.
Back button now works as expected. Fingers crossed it stays that way...
Hello there! A friend of mine gave me her Galaxy S4 mini GT-9195 LaFleur (pink one). She was going to throw it away as she dropped it in half a glass of water. Apparently, some water got into the bottom of the phone and got the Home button stuck. As a result, the phone permanently gets the hardware Home key signal and is almost entirely unuseable. I managed to get past the PIN-code screen by entering the PIN while manually holding the Home button, but that's about it.
I also managed to root it with the intention to install CM which features disabling the hardware keys and using on-screen keys, but I wouldn't be able to get to the menu to disable the keys. I've also found other methods, but they involve editing files on the phone itself, which is impossible because of the Home key being pressed about 3x per second.
So my question is: is there a file I could flash to resolve this issue and disable the home button or disable all hardware keys? Or is there maybe a rom written with these keys being disabled by default, and on-screen keys?
Any other help or suggestions are of course also very welcome!!
Thanks!

None that I know of!
The key is probably malfunctioning because there is still moisture in there and it's shorting the switch out (or possibly it's now what is the salts etc left after the water evaporate). In first case put it in an airtight container with with the battery out & cover off & a lot of rice and leave for a week or two. If that doesn't work (better option I think) take the cover off and remove the back panel, take out the power board PCB and clean the contacts of the switch and ensure there is no moisture anywhere in the phone e.g. under chips etc. (also check other switches etc water may have condensed in other areas) (you can buy little phone tool set on ebay etc cheaply). Should then work normally ........:fingers-crossed:......

Thanks, but I've been able to solve it differently. The phone was kept in a airtight box with rice and anti-moisture silica for a few months, but the problem continued.
I noticed that after being locked a few times, SOMETIMES I was able to hold the home button, and then access the menus. I then managed to root it, add soft keys in build.prop and disable the home button in the generic.kl file in \system\usr\keylayout...
Problem solved! It's a functional phone again, without a hardware home button.

Oh right, so you managed to get in to root it etc. :good:
(yes rice doesn't always work as moisture can stay trapped in areas like the buttons contact pads underneath, I think. Even if dried out contaminates can remain that can short switch)
EDIT: Fixed it (for now). Copied from my post on site 2.
What's up guys, I'm sorry for the late followup. It turned out, that I was too lazy to send it back. Now, almost a year later, I'd gotten into fixing phones and got the courage to open up the device and see what's up with the power button. It felt like the issue has been a bit less noticeable recently but I checked the replacement parts prices and how to open our phone up.
I think I've fixed the issue by adding one layer of electrical tape over the button-contact. I believe the issue is that the pin a just a little bit too short to reliably properly click the button.
Short tutorial:
Turn the device off and remove the simcard bracket.
It's actually super easy and you don't need to screw or remove anything. Google "Xiaomi MI A2 LITE disassembly screen battery smontaggio" you'll find a video, in the beginning the guy shows how to remove the backcover. I've used a hard, plectrom-looking "opening-pick" at the bottom, then carefully but firmly around the sites. You don't even need to remove the flex cable from the back, just make sure you don't rip it off. Cut off a short bit from the electrical tape, tape it from the battery to the contact, so it doesn't fall off. Close the case again, turn it on and check whether the powerbutton still clicks (doesn't stick) and test the screen lock. Post back if this has worked or if you've tried it.

Does anybody have a similar issue?
I've ordered the device from gearbest to Europe. Everything worked nicely.
However, recently when I hit the power button it sometimes triggers the double click interaction and opens my camera. I've tested a few ways to press it slightly from the side, with more force or less. However it will 1/3 times vibrate and start the camera like I had double clicked it, it's more likely when I hit it a bit too lightly though. Could it already be worn out after 2 months? This never happened when the device was new as far as I ran remember.
Yes I'm aware that I could change the camera shortcut but this doesn't stop me from worrying about whether my powerbutton will give out soon.
I was using the phone happily in the case Xiaomi has provided. Dropped the phone once and got a little scratch on the VOL Button but other than that, nothing crazy has happened. Does anyone have a clue whether they will still replace it? I'd gotten it in mid-August.
<message deleted>
Buttons are usually the main gate to "planned obsolescence". I bought this device after my nexus 5 power button started working funny (I physically removed it and worked only with gestures). So, now I try not to press the button unless necessary. I unlock with fingerprint, and lock with Greenify.
In other words. Make sure of it, if the button starts working funny, I'd file a warranty claim. Or it won't last long and warranty will expire eventually. It can happen with this device and with any other piece of tech.
My opinion.
If you do place a warranty claim, let us know how xiaomi's customer service works in Europe.

when you dropped it
the power button may have got stuck
this is possible and I've seen it on some other devices
you can open it yourself if you don't care for warranty like i do
but the safest option is to claim warranty and yes they would replace it

I have the exact same issue. It started when I installed the Oreo update, but it could be a coincidence. I'm still looking for a fix.
It also happens to me, and I didn't drop the phone... Is there a way to change the shortcut to, maybe, press the power button 3 times instead of 2?

It happens to me too, I disabled the shortcut and just not using it right now. I don't think there is a way to change the shortcut

And i think it's a software bug, not hardware..

It obviously is not a software issue. This means that they've used cheap contact points on the button if this happens to many of us. This is a hardware issue.

I'm having this issue since day one. It is obviously software, otherwise the same contact problem would occur when turning the screen ON, but it never happens. Solution is to disable the feature under System -> Gestures -> Jump to camera.
i also dissabled the camera gesture because of this issue.
im sure this is reasoned by a more or less loose power button and not an software issue

How can that be a software issue? Same issue happens to me whenever I use the power button, either to lock the screen or unlock the screen. Also if it was a software issue, it could be fixed via installing a GSI. That doesn't fix it either.

Let me break it down and you can tell me if I'm missing something.
1. Many users are reporting that the camera app starts when pushing the power button to turn the screen off.
2. They are not reporting any other issue with the power button, like the camera app starting when they try to turn the screen on, the button being irresponsive, or the camera app NOT starting when they deliberately push the button twice.
3. The problem reportedly goes away if the double-push gesture is turned off in settings.
Do you still think this is a hardware issue?

When I disable double press gesture from Gestures, still when I sometimes hit the power button, the phone locks and closes the screen and then turns the screen on again which means that it still registers one presses sometimes as double presses. Also if you've ever used a keyboard or a mouse or anything electrical with buttons on it, these appliances do the same sometimes even though you tap one button they sometimes register it twice. Which is a hardware issue. I still can't see any software issue here. When you disable the double press gesture, it doesn't launch the camera anymore but it turns on the screen after locking it (sometimes as usual)

Yeah me neither. They don't look like they're going to fix anything or listen to users either. I'm happy with stock Android though.
Hi guys, for me, the problem has fixed disabling the option "Power button lock the phone", and set the option "Lock automatically": immediately.

I have a weird issue where occasionally after I unlock my phone, my screen doesn't respond to touches.
The phone works and responds to physical button presses but not touch.
Not sure exactly when it started happening but I've noticed this since last week.
Any idea what might be causing this?
I'm running Android Pie 52.0.A.3.202.

Got the same issue on 52.0.A.8.50. Usually opening the app drawer then hitting back solves it - otherwise none of the virtual buttons work.
Searching the web it seems touch screen issues are pretty common on this phone. I'm a bit surprised there isn't more being said here about it. Some experience delayed response, dead areas and no response at all. I have all those issues. Yes I am on the latest firmware. I bought the phone used with a cracked screen. I checked it out and everything seemed fine. I didn't use the phone, just set it aside til replacement screen came. I should have used the phone to thoroughly check it out but didn't want to go through the set up process as I was thinking of B/L unlock and root. New screen came, put it on and seemed to be working fine then screen would be unresponsive. I did factory reset, software update, software repair, went into settings and made sure sure everything was good there, nothing helped. The center of the screen (it's low and a bit off center) is pretty much dead. To open launcher I have to touch and hold near the top of the display. Touch and hold apps is tricky. Usually the app just opens. When I do get it to hold, I can't drag it anywhere. Also, icons in the drop down menu cannot be rearranged or edited. I can swipe up/down, side to no problem. Whenever touch goes dead completely, the home, back and minimize buttons go grey. Tapping the power button gets them back functioning again. . Function test fail. Free draw lets me make a few seconds of scribbles then freezes. The x and rectangle block draw does the same. Tapping power button does nothing to unfreeze either. The color test pass even the block one where you toggle on/off sections of the screen in blocks. It's really weird. First impression would lead me to the screen but it really acts like a software issue. From what I've read so far this phone uses two different display drivers. I not seen anything on how to change that and it would more than likely mean B/L unlock and root, which I'm not against doing. I would just like to know definitively if it's hardware or software. Any input would be greatly appreciated.
Thanks

Maybe the Screen Connector wasn't 100% clean.
Or not only the screen is damaged.
I heard that the touch problems are mostly fixed with PIE. The closed source clearpad touch driver is..... Hoping Q gives us an further updated driver.
You still get sometimes ghost touches on higher workload or if the keyboard app is slow, but if you have dead spots the hardware sounds damaged.
