I am having a similar problem. The down dpad only responds when extreme force is given to it; along with the row of horizontal pill buttons (ok, ie, mail, today). i took it apart and tried reseating everything to no avail. i also have a new problem, my display is fuzzing up or showing up in 256 color

There was a chap on here (fluffcat1) that sold parts for the m2000. I have bought from him and can recommended.
You can buy just the new button pad for the bottom of the pda for less than £10 and then just make sure you have the correct TORQ screwdrivers to open it up.

the down button on the keypad sucks on all b.a's
i was lucky enough to get a good one that theres barely anything wrong with.
the only problem is wen i press down and right (to get the 45 degree south west direction) it doesnt work, or its VERY hard to get to work, but thats it.
i think its just that the b.a down button sux, probly a design fault.
also check maybe a bit of dirt lodged itself under there. this happened to me once andi've only had my b.a for 2 weeks!
gah they shud really put more time into designing these things, i'll never forget my v3 <3

Reset when sliding out keyboard

Hello boys
from about 1 week i have this problem on my device, if i have the keyboard out and write an sms or typing an url when slide the keyboard in the device automatically reset itself...
anyone knwo this problem or the solution ?
Thanks for the help
Nicola

Hi,
I have a problem with my keyboard too, I've searched the forum but i didn't see the same problem as i have or the solution. My phone's screen turns off when i slide out the keyboard. Actually phone stays on but the light of the screen goes off. when i slide it out i'm able to write something or make calls. when i slide it back, screen keeps itself off and i press the sleep key "2 times"!(screen looks like off but it isn't) to reopen it again. I press the sleep key for the first time to turn the screen actually off, and press it one more time to turn it on again. i did a soft and a hard reset to the phone, didn't solve it. I don't think it is a software problem but i hope it is

These are the photos of the occasion.
The screen keeps itself on until the end of the slide. it turns off then. when I slide it back, i can see the backlight of the screen and the light of the buttons.( i don't think that you would see it on the photo, 3rd photo).
I'm waitin for your help guys, thank you so much.

Isn't there anyone to help my problem? I'm waiting for your answers..

I'm also having this same issue. When I slide the keyboard in it just turns off sometimes. At first I thought it might be a physical issue with the internals of the phone and the sliding impact of the keyboard was causing it to reset, but it doesn't do it all the time for me. I can jam on it and nothing happens sometimes, or other times it resets from a gentle nudge. I am running Energy GTX from August 26 or 28, whatever version that was.
I also have this issue now where my end key is unresponsive. Doesn't. Work. Ever. and that is so freaking annoying. If anyone has any insight here PLEASE share it.
Thank you.

Wow i just saw your message and suprised. Is that my phone you're using? Because I have that end key problem too. It works when I press too hard. And I have 3rd problem now. I think my phone's microphone is not working. People i'm talking on the phone is always complaning about that they can not hear my voice or it's too low. Now I have three problems:
1. Phone is turning itself off when i slide the keyboard out.
2. End key is not responsive.
3. Microphone is low or its broken..

Maybe reflash your phone to origional rom.

I was using WM 6.5 without hardspl when the problem occured. then i did hardspl and installed custom roms, i even tried with WM 6.1. It didn't help about any of it. I'm used to not using the keyboard actually, but the problem with microphone is annoying..

Same problem with the keyboard

I have the same problem !!!! Did you manage to resolve because I am sure this is software relatred. I had android on my phone prior to this and fixated that the issue is coming from this

Had the same keyboard issues, found that it was a battery issue. when you shut the phone, the battery would loose connection.

bluewaterkayak,
more info on the loose battery connection.
i have the same problem with sliding the keyboard down and the screen turning off. closing it, pressing the sleep button 2x, turns the phone back on. i can slide the keyboard down just enough and hold it to type out a text, any more and it'll go off.
THIS IS SUPER ANNOYING

Bumpski. Really need this fixed.

What ever you last installed take it off. If not you might have to go factory restore

It's definitely not a software issue. The screen itself somehow gets disconnected when slid up all the way.

Took it apart and found nothing obvious wrong. Is there something to look at exactly when the slider is at the end of it's travel? The cables seemed fine. The problem only happens at the end of travel.
I cleaned the slider area and pried some contacts down. Nothing. Put it back together and same problem.
Ideas??

See here:
http://forum.xda-developers.com/showthread.php?t=561151

Tried the fix posted in the last link with Kapton Tape.
Didn't work.
Any ideas?

I have the same issue. My old VZW TP2 is sitting in a drawer in my house because people kept saying they couldn't hear me on the other end. Also on my new one, when i slide the keyboard in/out sometimes it turns off, not always though. I figured it has to be a hardware issue as well, if i do it slowly nothing happens but if i just slide it open and let the springs kick in, it usually cuts off once it 'snaps' to the end of the sliding path.

Volume up, Menu and Home key not working!

Hello everybody! My htc desire's physical buttons(actually just the volume up, home and menu keys) don't work...I press them but nothing happens. Well, they work sometimes, but when they don't I reboot my phone, randomly press some buttons, and they start working again. I just don't know what the fault is. Im on MildWild CM 4.3. I think the same problem was with other firmwares too. Can you please solve my problem?

If your device is under warrantly just send it to htc. It's a hardware problem, not something that you can solve with a script.

Ah, so you're telling me there's nothing that can be done to repair it? Cuz, my device isn't in warranty(I just replaced the casing)...

I don't know.. I don't want to be pessimistic, maybe you can search for similar problem in internet and a possibile solution, not just for Desire but in general for devices that have hardkeys. Maybe like use a spray for electric contacts while device is turn off and wait that it's completly dry before turn it on. Good luck.

I can't remember it, but I think that this problem appeared only after I got my casing changed. Could the technician have done something wrong? Can I send it to the man that changed the casing?

It's probably just some dust that gathered underneath the buttons. I had the same problem with the volume down button. I used a needle to clean the dust around it, and then it worked perfectly.

I dont think it could be due to the dust, cuz there are three buttons which simultaneously stop and start working... It's a bit strange tho..

I have issues now with my power button. It's unreliable... that is, the button sometimes works. Sometimes when I press it, it opens the shutdown menu..
Started all of a sudden. Not sure how that happened... and it's out of warrenty for 4 months now..

That is why I use Button Savior

Same!
I am getting the same problem. I have replaced the keypad flex with a new one and still getting the same issue. It would start working randomly like if I open the browser and open many tabs, then it would work. Funny thing is that they would not even work when I go in recovery.
My desire is 2yrs old now but I still love it.

Same problem here.
Mostly happens with Home and menù. Less often with volume buttons.
For now I'm using the "button saviour app" workaround, but if is something hardware I will know it very soon... (made a copy of my rom on a friend's HTC Desire)

All three buttons simultaneously! Buttons usually fail gradually one by one and drive you mad finally. I would put my money on the keypads being misaligned during whatever you got done with casing. Take it back to him.
If its some kind of misalignment no amount of sprays will help.
BTW I use zmooth for button conservation

use soft key instead

I had the same issues : menu button working randomly, had to press very strong on up/down volume buttons.
I've dismounted my phone (using this : http://www.formymobile.co.uk/desiredisassembly.php ), and I saw that there were a lot of dust, hairs.. I tried to clean up/down volume buttons the best way I could, and they both work so much better now! Not totally perfect though.
By the way, I noticed that there was a lot of compressed dust in micro-USB connector and was able to remove it fully (thing I couldn't do without dismounting phone).
I didn't want to go farther to access menu/home buttons because I didn't have time and Menu button works quite OK.

I have the same issue here with the volume buttons they tend to get unresponsive and unreliable.
Even though all the parts were renewed since six months ago, the volume buttons are probably bad designed?

You could replace bad working buttons' functions with others'. My volume down isn't working, so I made my search button act like a vol down.

Buy the new one

Power Button worn out? Accidentally starting Camera despite clicking it only once.

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

It happened for me as well.
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)

Not for me, so it's possible that these are actually two different problems with this phone. I wouldn't be surprised. :laugh:

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.

The fix
What's up guys, I'm sorry for the late followup. It turned out, that I was too lazy to send it back.

I changed the power/volume button assembly outright just the other day, and so far I'm not getting this issue anymore.

Touchscreen Occasionally not responding

Greeting,
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.
