Question Touch/swipe delay on Poco F4 - Xiaomi Poco F4 (Munch) / Redmi K40S

For a while, I've been trying to figure out how to word this touch/swipe issue I'm having with my POCO F4. But now, I'm able to reproduce this, and hopefully this will help in identifying the problem.
1. Press and hold the screen with one finger.
2. Press and hold the screen with another finger, without moving the first one.
3. Release the first finger.
4. Slowly swipe with the second finger.
There is a noticeable delay in when the swipe actually happens in this case.
This has not happened in my previous device (Redmi K20 Pro), and I'm having the same issue in stock and EU roms (MIUI) as well as ArrowOS (AOSP). Is there anything I can do to fix this issue?

If you turn on performance mode this issue will gone.

There is no such option in ArrowOS, which is what I'm using right now.

Update: I have rooted and installed NGK in my phone with Arrow OS, and this issue still persists.

I've attached a video of the issue. Note the delay in move/swipe detection when the right finger is moved after lifting the left finger.

So I suppose my phone has the most weird hardware problem ever.

Please don't move my thread to Q&A as I already made a thread there but no one replied.
So what happens is that a touch is randomly registered on the screen of my phone sometimes when I press the power button. This isn't an HTC lockscreen specific bug as I have established it happens with PowerAmp lockscreen as well. I have done a full factory reset and it is still happening.
I don't use lockscreen security so the obvious problem with this is that so many times upon pressing the power button a notification is clicked and immediately opened as a result. This problem can be avoided by using double tap to wake but it's far too easy to activate by mistake so I can't stand it.
Repeatedly pressing the power button will not reproduce this result, it seems to only happen when the power button had not been pressed for a few minutes. But this cannot be a bug related to sleep mode since this happens when playing music as well.
So what I would really like to know is if there is anyone else with this problem? My M9 had been so perfect all this time but this has just ruined the experience. I don't exactly remember when this problem started but I do know it wasn't there from day one.

Seems like a hardware problem. Something presses your digitizer (touch screen).
If u have any screen protector , remove it.
If not, take it to warranty.
Good luck!

HTC doesn't provide warranty in my country so I am outta luck. I don't have a screen protector so I guess I am screwed.
I guess I won't be buying HTC again. I already tolerated the crack on my bezel but it seems every HTC phone has some hardware issues. It's too bad though because I loved HTC software and performance, the M9 had been nothing short of a spectacular phone for me.
It happened to me too when I used a stupid Samsung charger. Try another charger, I don't know why but sometimes the current of power is somehow overflowing the chassis of the phone that the digitizer thinks the difference is actually a touch on the screen.
I want to update this thread. As it turns out it's 100% a software issue. How I figured this out is that when I turn on "double tap to wake" this problem completely disappears even if I still use the power button for unlocking. So basically the bug comes into play when you turn off double tap to wake as it is turned on by default.
So is anyone not using double tap to wake? Are you experiencing this problem? Unfortunately I find double tap to wake extremely annoying as it is so easy to wake up the screen.

That's quite a unique software issue then. At the risk of sounding like an obnoxious tech support guy, I would absolutely backup everything and then just factory reset (or wipe and reflash your custom ROM) when you get the chance and quickly check if the problem is still there.
I've been using double-tap and it has actually been the opposite for me - I find it annoying how hard it is to wake up the screen because you need to hold up the phone vertically before double-tapping, rather than just tapping while it's lying on the table or in your pocket.

I have already done a factory reset to no avail.
That's strange because I can activate double tap to wake from any orientation.

Oh my bad re-read OP and saw you already mentioned it.
Hunh, I stand corrected I guess, since now I'm able to wake from having it flat on the desk. Could have sworn that didn't use to work. But still, I'm not by any means accidentally waking it (if I pick my phone up, it pretty much means I want to use it).
I can't replicate the digitizer anomaly, so not much else I can say other than good luck. Have you tried custom ROMs?

It might take a day or 2 of usage to replicate the problem, it doesn't happen most of the time.
I wake up my screen accidently sometimes when putting it into my pocket after locking it which is hugely annoying as the lockscreen is kinda easy to unlock once it's woken up.
I really can't be bothered with custom ROM as I am done with all of that. I'll just live with double tap to wake.

That's the design. When lying flat, you can wake the phone with a triple-tap.

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)

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 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.

Touchscreen problem

Hi, today in the morning i noticed an issue with the touchscreen, especially, on the left edge. I noticed that issue while i was writing and trying to switch the key of numbers and letters.
While i try to write and press "?123 or ABC" key, sometimes it doesn't work and i have to press twice.
Have u ever noticed something similar? I have tried by changing the keyboard, restarting, calibrating and I can't fix the issue.
Thanks in advance.

same too , I hope it is not a hardware's issue.
I have the same problem. In my case, the other side of the touchscreen has the same issue as well (Gboard enter button). Did you guys check the touch sensor test (the one in diagnostics menu -> additional tools)? It seems that only two squares are affected. The left and right outermost square in the penultimate row. Try tapping fast, it's sometimes not registering. I really hope this is not a hardware issue though...
Have you tried to disable screenshot gesture? Please try it and report if the issue are resolved. I don't have a rdm8pro but on other redmi i have the same issue and the screenshot gesture of miui create the problem.

it's exactly the same in my case , I have noticed that more happens if you touch repeatedly in the middle of the screen and then at the ends
sorry for bad english
I went to a local Mi Store earlier today and the unit they have on display suffered from the same touch screen issue. I don't think replacing the device would help as it seems that a large amount of them might be having the same problem. If anyone's device is functioning correctly, please let us know.
This is just in the corners , I noticed to.. when I want to press 123 to go to numeric pad, I noticed that the screen dont react in some times..that not the screen issue, this is more like ..I dont know how to explain it on English..but everything is ok with screen when you press the right place..
Try press this line that I marked on this screenshot and you will se that the display is not responding.. this is not hardware or software error.. this is jus the line on keyboard that have no function and not react when you touch it. But when you touch right place on number 123.. everything is ok..
So ..your phone and everyone else is working fine.
Also this is just happened on keyboard..on other apps,this place on screen also like in CIT test working..

Try touching the highlighted tiles and then compare it to other ones. Look at the attached screenshots.

the touches have to be fast, if you make them slow the problem "disappears"

You mean you are unable to access this particular test? Just tap the 3 dots in the top right corner of the screen when you get to the CIT test menu. Then select 'Additional tools'. Tap the 8th item on that list which says 'Touch sensor' and you will be greeted with that test screen.
apparently if it was a software problem, update a few minutes ago and the problem seems to have been resolved

Question OnePlus 9 Pro, Power Button Double Press

Hello,
When I press the power button once, it presses twice.
I read that other users have the same problem, and you ?
OnePlus 9 Pro, Power Button Double Press
Thank you for your help.
Regards,
I don't, yet
Did it happen right out of the box ?
A few weeks after
Mine does the same and support just wanted to flash my device
Had same problem, so I disabled this option.
Haven't tried with the newest oxygen though.
This has been happening to me as well and I was able to Mitigate it temporarily (it seems to be coming back slowly) by disabling and re-enabling the Gesture (settings -> buttons & gestures -> Double Click the power button -> camera)
I am on Oxygen 11.2.8.8.LE15BA on my unlocked tmobile 9pro -- using omega 5.4.61
This started happening recently to me too and honestly I don't think OnePlus are even going to fix it when I RMA it... I'll probably just pick up the Pixel 6 Pro and then RMA/sell it after

Did you flash a tpd disabler module, one causes this that removes pref
