Ghost touches - Xiaomi Mi Max Questions & Answers

Anyone experiencing ghost touches from xiaomi mi max? I have sometimes experienced mild ghost touches. Do you guys have any clue if this is a hardware or a software issue? I also dont have the option to calibrate secreen when i access hardware menu via *#*#64663#*#*, touch sensor and long press menu. I only see the option pass/fail. Please help!

I have not experienced any ghost touches on any firmware. I would know because I had it on my S7 Edge.

No Ghost touches here. Had all the new Firmwares out there and nothing to see.
Maybe you can do a Wipe and see if there is any touches ?

[Q] Slightly faulty Desire screen

I have a Desire with a screen that no longer responds 100% correctly to touch input. There is a small patch in the bottom right of the screen which registers movement once pressure is already applied, but fails to respond when touched directly. It's not a particularly big region but is enough to prevent 3 keys registering touch input. Besides using something like swype, does anybody have suggestions to get this working?
Any hardware/software tricks that are likely to help with this?
If the phone isn't rooted and a factory reset does not fix it send it back to htc. Unless the problem is obviously the users fault.

Screen Sensitivity

Is anyone experiencing extreme screen sensitivity? My phone seems to pick up pressure from the outside of the frame and launch random apps, even though i am using my finger to press on other areas of the screen. Not saying that I am holding the phone correctly, but it really seems weird.

only thing I can think of would be check and see if "increase touch sensitivity" option is enabled.
settings>device tab>display> at the bottom "increase touch sensitivity". make sure that option is disabled.
Mine was way too sensitive also, and increase sensitivity was unchecked. Since I put a slim case on, I've had no problems.

Touch issue

It's a huge problem for me. I've noticed the touch problem occurs only in the middle part when I can see the touches.
It scrolls up and down by itself. touches many time that drives me crazy. It's not allowing me to do anything. And it happens randomly.
I have no screen protector. And I have tried disabling developer part, disabling knock, and factory reset. but no lock so far.

Quick screen 'taps' register as 'drags' after screen replacement

Hi everyone.
I have recently had my screen replaced. After playing around, i quickly noticed that my keyboard screws up when i start typing.
The faster i type, the worse the problem is.
I checked touch response times and achieves normal times of about 60ms, however, i turned on touch overlay in developer settings and noticed that if i touch opposite sides of the screen quickly (to simulate typing), it would draw lines between the touches as if i was dragging between the two points.
This is what causes my keyboard to do funky stuff and heavily lag when typing fast.
Please note that this never happened before the screen replacement, and a hard reset didnt fix the problem.
Is there any software fix for this, or do i need another screen?
thanks.

I mainly work on iPhones, but it sounds like your digitizer is out of calibration. Don't know if there's a software fix for it, but hopefully this will point you in the right direction. Also I'd take it back to the place you had it repaired and see if they can fix if it's still warrantied.

Ghost touches in pocket? [Proximity sensor issue]

Anyone think that perhaps the proximity sensor of this device doesn't work always?
After using my phone if I put it in my pocket without locking I expect that it will not register ghost/accidental touches but I don't think the phone handles that very well. Often when I pull out the phone I can see some random screen got opened.
Are others also facing this issue?

Not random screen opening but once i remove it out of my pocket i get a warning screen saying accidental touch protection is on or something.
Or sometimes a clock, the one on the lock screen where you just tap on it and it zooms in the clock.
Have you turned ON the Accidental Touch Protection? I initially had Ghost Touch problems during jogging but with the change of placement of the phone, i now dont have the problem. Make sure that the screen faces the pocket side not the thigh side. Most of the ghost touches happen while interaction with the thigh.

The setting was already on. Anyway I toggled it off and on again just in case. Making the phone face outwards in the pocket may work as a suggestion, but it still probably implies that the phone is not doing a good job in blocking these accidental touches. I also like the screen inwards in case I hit a table edge or something.
The other setting I did is to ensure the phone locks itself quickly after the screen goes off. Earlier I had it at a higher value and its possible the device was switching on to an unlocked state. This is working a little but in my old devices I recall I was able to pocket even if the screen was on and i didn't really have this issue.
Accidental Touch option don't working well as need it.
Sometimes working and sometimes don't but proximity sensor working like a charm
Think it's a software bug.
Working like on a wind
