Apps random minimize

Hello everybody,
today I have to ask if somebody has a solution for me
When I click sometimes on different apps just with the finger they minimze. I don't know why is there a special gesture or something? Its really strange..
FTouchFlo is disabled of course..
But maybe my device is just going to die
You know what, i have had that happen to me too!! Mine mostly happens when I press the centre key in the dpad, but i think it has happened one other time when i didnt use that key too.
I dont think its your device, might be something that has to do with WM6.1. Never had that happen in WM6.0.

This behavior is very strange..
I didn't noticed it with the dpad keys yet, just when pressing the touch screen somewhere.. It also seems to happen more often when the memory is very full or pressing on the right screen edge. Regards

Well, didn't found any solution yet but will looking for..
I agree with ICE, it does happen to me when using touch screen also. Maybe its an alignment issue?
It is an alignment issue! I am having this too! Touch screen smoetimes thinks that you press upper corner of the screen! I think this is Windows Mobile problem but also it may be a hardware issue!

So I might be able to fix that when I align the screen again?
I have the same problem.. it does it every once in awhile.. so annoying

I guess early WM6.0 releases had some screen alignment issues, but the more i read, it is related to hardware issue...LOL
I have the same problem!!!
Never had screen alignment issues, but my screen has damages from stylus on the "X" button from pressing there and on the scroll bar from scrolling while surfing the internet, I think that is the cause of the problem with my device..
I must say it is really annoying and made me realize I will NEVER use stylus in my life..
Just my 2 cents..
I've noticed the same problem occasionally, and from memory it (maybe) happened a lot more on some of the early WM6.1 ROMs. I haven't noticed it for a while though.
Do you think its the same as in the wiki? HT646 on http://wiki.xda-developers.com/index.php?pagename=Hermes_Problems
Where the right corner keeps touching. If you've got any xbutton installed, its bound to minimize. Some of the problems farther down link this to the screen heating up and eventually not working till it cools down.

Well it happens even in the morning when the phone is fully charged, and hasnt been used/touched/handled in over 8 hours, so I doubt its a heat issue.
Shamanix, are you saying this whole problem may be caused by the HTC X Button software?
Happens to me also but only since I switched to 6.1 ROM's
I also had this issue on 6.0.
Can't really believe that this is an hardware bug, maybe a special hermes "feature"
Yesterday, when I was scrolling over the edge I saw the x button going down *lol*
Would be interesting if kaiser users have the same problems.
No I am not saying it is because of X-Button software... I said that I have damaged my screen when I was pressing "X" and "OK" button with stylus in the top right corner and that I have damaged right part of the screen where the scroll bar is again with stylus while I was surfing the web and scrolling so now when I press over the damaged area ( right side of the screen ) I can see X button going down just like Pay said..
So my problem is in damaged screen...
You can`t see the damage, but you can feel it with the stylus...
i have apps closing in random occasions as well. it didn't happen before using wm6.0 but it happened on almost every wm6.1 rom i flashed. i try avoiding the htx x button so i don't think it's related to it.
Im on WM6 with ftouchflo enabled and x-button bind to close apps. Happens to me also sometimes A bit annoying but I think I'll manage.
There appear to be many issues concerning the screenpart of the Hermes. I am not suggesting that this problem actualy is one of them but you might have a closer look to the space between the screen and the plastic of the housing. My whitescreenissues and the screen alignmentissues many people suffer from are caused by the thin layer of foam that HTC sticks the screen to the housing with. I recently put some new foam/tape in between and it helped me with my whitescreen issues. In the beginning I put to much and at that time touching the top plastic parts caused all sorts of reactions normally caused by touching the screen,.
Just a thought...

[GT-I9195] Touchscreen problems

Hey there,
sometimes after using phone for days, touch screen dont respond correctly on some specific placed on screen.
for example if i hold down at one point on the screen screen is thinking i press also like 1cm down and jumps up and down.
i will wait to re-produce the problem and post a screen from touchscreen with debug menu *#0*#
happens at least 3 times for now with multiple firmware, since a restart always is the solution i think its a samsung related software problem in stock rom.
Did you apply any screen protectors? Its a common issue with cheap ones
No, i dont have any. Also the its not always at the same position.

Touch Problems with HTC 10

Hi HTC fellows,
I have bought htc 10 three days back. Initially there was no issue with the phone. However, after an update of around 300mb came, the phone started behaving abnormal.
When i try to drag the app notification bar down, it doesnt respond , instead the home screen either moves left or right.
Sometimes the camera button stucks and doesnt capture photo.
Sometimes the keypad behaves abnormal.
In short, the touch is not responding right.
Please help me guyz.

htc touch screen definitely responds differently than my moto maxx did.
sometimes, close is "good enough", and the screen responds with very-close-but-no-contact touches.
also, the edges are very sensitive. sometimes i hold the phone in a manner that hinders desired response.
i have intermittent text input problems, but im not 100% sure its related to touch.
i've had to retrain myself on this device. i would love a way to trim the sensitivity.

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

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.
I recorded myself doing it here, so you can see how easy (or hard) it is: https://youtu.be/q8kaY-v0q_Q

(FIXED) Bug at the bottom of the screen which mistakenly counts each touch twice

I use protective glass on the screen. The bottom of the screen is very sensitive, and mostly when I press a button on the bottom row of the keyboard, that character is repeated two or three times. Or if there is a button in that area, such as the Mute/Unmute button on the telegram pages, when I select the button, it's been selected and then return to the previous state, as if I pressed the button 2 times. I don't know if anyone has this problem? And whether this problem has something to do with the protective glass or not?

Sounds like it's a issue with the protective glass, I also have a screen protector applied with LOCA glue & haven't experienced this issue

So should we conclude that as a hardware problem? Is it not possible to fix it by providing a software patch from Samsung?
I finally found the cause of the problem.
