This is realy annoying. Probably its an hardware defect.
Did you try an reset? Press Power and volume down at same time.
Otherwise use guarantee

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 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.

[Q] Touchscreen Sensitivity

It seems that there are some dead sensors or something in the upper right hand corner of my screen.
I'm getting these 'phantom touches' that keep pressing whatever is in that corner.
I'm wondering if there is any way to turn this part of the screen off, so it doesn't continue to register touches that aren't actually happening.
Does anyone have a solution for this issue?

Okay, that kinda sucks. I guess it is kinda old after all. Thanks for the input though!
My cousin used to have this problem, she couldnt touch some parts of screen So she needed to use her phone on landscape mode
In order to see what parts have problem on play store write toucscreen test etc
No software solution
it's a hardware problem ..Your touch screen needs to be replaced

screen can't turn on without force reset (P600)

I bought my device (P600) a few month ago,
and suddenly (without changing rom/karnel or doing root) i got a big problem -
when i push the button that close the screen(turn off the screen but the device is still on) or if the screen is turned off automaticly, the screen stay off forever. Even pushing the power button doesnt turn on the screen.
The only way to turn the screen on again is to reset the device (by pushing the power button long press).
I almost sure that the problem is a hardware problem even that it's look like a software problem because after i saw the problem i changed the rom and the karnel to other option to check if the rom/the karnel is the problem and the problem didnt solved.
Someone have a clue which element make the problem?
Thanks (and sorry for my bad english)

I'd bet money on it being a backlight issue.
Test it again in a well-lit room with a bright lock screen wallpaper, something with a lot of bright color. Once the screen turns off, wake the device and look carefully to see if you can see anything. You might have to tilt the screen, but you should see a very faint, dark image.

Amazing that's was the problem!
There is a way to fix it? What is the component that causes this problem?
thank you so much!

Unfortunately I don't know of any solution other than sending it in for warranty coverage or replacing the screen yourself.
I've seen a couple of other posts on XDA involving the same issue, but never saw a solution. I've even seen this issue a couple of times IRL (not on my device, thankfully) and have not been able to find a solution. The two times I've seen this issue, the backlight level could not be adjusted, either. Whether it was set to automatic or manual brightness, it would never adjust, the backlight was locked at a constant level, until the screen turned off, and then the backlight would NOT come on again until the tablet was restarted. Reflashing stock firmware and doing a factory reset did not help, either. On one of those devices, the backlight DID start working again for a while after a manual wipe of internal storage, but only until the tablet was restarted, and I think that might have been a coincidence, I was not able to replicate that again.
So in short, I'm afraid I don't have a good solution other than hardware repair/replacement via warranty.
this has just happened to mine - will have to send it into repair, but it had CLEAN ROM installed so they might argue re the Knox trigger - really annoyed about this!

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.
