ooooh man, finally someone with the same problem, and cant find why its happening

it happens randomly, but when its happening the only way i can stop it is tighting it as if choking it. i dont want to send it to warranty.....
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] mist813:
Well I am going to send it to warranty next week. I dont like the fact that I Will he without the Phone for a month, but hope they Will change the screen and it Will be fine.

My first xiaomi, always had Samsung and everything was alright. Phone in overal is great but I am very disappointed with this issue.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] herniskhan:
Im the same, just noticed, after 2 days without issues that i was recording a telegram audio and it happend, idk its kinda clueless always
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] herniskhan:
Man, definetly it has something to do with software, just a few moments before posting this i had the issue and it didnt want to leave so i had to restart the phone, first time this way.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Shpagata:
Guys I found out what's causing the issue!!! It's not software or hardware. If you have the original Xiaomi case that comes with the phone it causes the ghost touches! I tried removing it 2 times and each time I put it on I experience the ghost touches and each time I remove it they stop for 1+ day which means that the case is causing them. My guess is that tiny particles are stuck between the case and the phone making it do this.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Ottograf:
had this on my previous phone, had to rma it
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] herniskhan:
Just found i had a spigen clear case(bulky) and since i got back to Xiaomi's case it is happening a lot less than before.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] mist813:
My problem happens even without the case, and I used Nillkin Nature. Phone is in service currently. When it gets back I will tell you :)
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] babaroga73:
Lol, how can this be? I believe you, though.

But oem case doesn't even touch the screen properly.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] mist813:
Phone sent to Service. After two weeks it is coming back to me with replaced screen. In about two days I will check if everything is fine.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] herniskhan:
Im waiting for what u have to say man, cuz i tried to rma it but they have it under review since last friday and today its being so ****ing annoyng that i want to broke the phone man
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] mist813:
After screen replacement everything is Perfect ?
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] herniskhan:
Yesterday and today have been terrible, ill be sending the phone on monday, ty man, hope it will not happen again

Any update on your phone? Touchscreen problem solved?
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] slavke1976:
Problem arrive when using 3 finger swipe for screenshoot. there is solution on net about this problem, instead 3 finger swipe just use power buton and vo- for screen shoot
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Nathan98:
Ho boy, Looks like this is a common issue, I thought it's just me and I had to live with it with this ghost touch, Particularly when dragging the notification screen and clicking on the settings it won't respond had to do multiple times. S/W update, reset nothing helped. Last week one genius broke my screen and I had to spend and replace it. After replacing the screen I'm not noticing this issue anymore.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] mist813:
As I wrote, tried everything, also disabling screenshot gesture. Problem is hardware, after warranty screen replacement everything is working fine.

At first also had problem with dragging down notifications bar, screen was not responding. Then I turn on touch location in developer options and saw that there is ghost touch in that part. Day after Day it became more disturbing to the point I could not use the Phone.

You can buy whole screen on Aliexpress and change it by yourself if You dont have warranty.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] droident:
I hope Xiaomi fixes this for those affected. The Redmi 5 Plus had widespread problems with the touchscreen which is why I bought the Mi9T Pro. Not had this myself but I'll be fuming if it ever happens to my Mi9T Pro.

I've still got the Redmi 5 Plus and it's been pretty horrific - the issues started whilst it was in the warranty period and then continued/worsened from there on out. I could kick myself for not getting it serviced in-warranty. Xiaomi essentially sold a lot of people faulty devices; many complain of ghost touching / non-responsive behaviour over on the R5P XDA sub-forum like it's a ROM bug.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] ankitpatel351@gmail.com:
I'm also facing this issue of phantom touch or ghost touch.

It's really annoying. I guess screen replacement is the only solution as I've tried almost all options mentioned in various internet sources.

Xiaomi sucks..!
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Nathan98:
Hello Ankit,

If you read previous post mentioned by other users, some mentioned that Mi Service center do replace the screen under warranty, May be you can give a try with them.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] klemensjose:
I have the same issue. Tried different ROMS and also resetting the phone many times. Nothing helped. I think it has something to do with the seal of the phone. If you push it hardly on the top edge it stops for some time and then it begins again. also with different cases it gets worse or better.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Art.Skachko:
Hi, there is an answer to the question.

Judging by all the manipulations carried out, the problem lies in the contact of the contact group on the display module itself directly with the case and other details, or the chipset on the display module somehow shortens. On other models, the problem was solved by disassembling and making structural changes, which were expressed in the installation of some gaskets between the display module itself and the microcircuit.

If you try to slightly press down the display in the lower right corner, approximately in the area of ​​the speaker, you will immediately get the same ghostly clicks at the top of the screen, which confirms my theory and the same troubles on other models.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] BratPAQ:
I remember this issue with pocophone. With them it's caused by a particular model of screen. After warranty repair they will notice that there's no more ghost touch and the screen model was changed. I wonder how can you verify screen model on our model.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] Ak's World:
Help me please.. I bought 2nd hand redmi k20 pro.. but after 2 days touch giving me problem.. Notification panel up n down without touching display... This touch issue occurring after 4-5 hours... Is this hardware problem?? If yes then how many it cost to repair?

I am on Global Stable MIUI 11.0.3 ROM
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] ankitpatel351@gmail.com:
You have to get the screen replaced only. It may cost you around 7000 rs to 9000 rs
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] diegohps19:
I also have the same problem and exactly as you described, I've made countless attempts at repair and haven't achieved anything so far
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] kibakamui:
Can you send a photo of this modification on the structure, and what material used for the gasket?

I have this same problem, you described it perfectly and i want solve it.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] nnahin:
Just tested this, you’re right. Can't spend 1/3rd of the phone's price to get it fixed. What should I do? I'm clueless.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] ramir0:
if you can use warranty, go for it.

if not, buy a new phone sadly..

the fix cost aroun 1/3 or even 1/2 of the brandnew phone, and you still get a not official screen
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] nnahin:
It's not even a month science I bought this(Jan 19). I removed the case and it isn't happening now. Let's see if it stays that way. And sadly I don't even have warranty
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] karan11000:
This post gave me confidence in going to the service centre without worrying about losing warranty claims. They took a long, annoying process to acknowledge that there is a problem with the display module. Took almost a month to replace the whole screen. Now I'm just hoping that it doesn't repeat all over again. I'm tired of erasing data and restoring it all back again and again.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] ramir0:
lucky you. when i contacted to xiaomis service, they answered me that they dont cover world wide, so i must go where they sold it to me to claim for warranty. they wont even recieve it if i go to an oficial xioami store. saddd
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] ChrisAndroidnIOS:
I found another solution!!

Guys, I have another solution that worked instantly for me.

Weirdly enough, if you go into settings and search for pointer speed and then turn it all the way down to the minimum setting, it starts working flawlessly with no issues at all. I don't knlw why, but this is a serious flaw in the software and I hope Xiaomi is aware and tries to fix the problem.

Let me know if it works for you guys.

Almost sent my phone in for repair but i would have been without a phone for a while since i don't have any replacement. Good thing I found a solution!

(Might not work for you if you have a different issue, mine was going wild touching everywhere on the screen, opening apps and swiping stuff. Was unbearable!)

Cheers!

Chris
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] klemensjose:
Yeah thats what i am experiencing too. For me opening the back of the phone and loosening some of the bottom screws also helped a bit.

Can you tell me where the display module is located exactly? Would love to fix the problem.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] nnahin:
What do you mean by "helped a bit"? Is it fixed or still happenin?
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] klemensjose:
It def got better.

It is still happening but only sometimes for one or two seconds. Before it was almost unusable for 1-2 minutes.

I would also recommend to activate the "show touches" option so you can see where the screen "touches". For me it was only in the top bar and now it's almost gone as I said.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] nnahin:
I've enabled show touches, it's also same for me. I think its same for everyone. I don't have the tools required to open the back and I also don't have any previous experience with opening glued glass backs so I'm a bit afraid also. There are many mi 9t galss replacement videos in YouTube, can't you figure out where the contact panels located?
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] klemensjose:
So as I tested more now... I removed the lower plastic piece and cut the right part next to the speaker. now there is less pressure on the flex cable from the screen and so far it works better than before.

Got the idea from the JerryRigEverything teardown video.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] nnahin:
Let us know if you find anything further.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] klemensjose:
I guess I finally did it!

I made a quick video to show you how: https://www.youtube.com/watch?v=j0KCBOEjRjI
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] nnahin:
So the material has to be thick right, so it presses up against the phones display?
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] hwnbeast:
Update on if it has come back?
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] nnahin:
It was never completely gone for me. Maybe worked for 7 days but started again. 2 days ago I removed all the paddings and using it like this.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] hwnbeast:
Ohhh, really hoped we have a fix.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] lakshya14sept:
I had the same issue ,got screen folder replaced under warranty, the issue still persists. Maybe its some design problem the way screen enclosure is designed. Please help.

same situation
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] sreepad lucky:
So hi, Is anyone still using the k20/9T. I've been facing the ghost touching for more than 3 months now. Can't afford to get the screen replaced. I've read all the previous chat. Is there any update on the solution. The top area of the phone starts responding like crazy and it is unbearable and really frustrating. Any solution let me know
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] sreepad lucky:
Do you have any update bro?
[Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe] shivanshusuraj:
using with some kind half solution
[Android General] snoopy20:
Hi All,

I've had appalling battery life for a while typically dropping 30% in 3hrs and 90% overnight with the screen off, the software as clean as I could get it (all Google apps disabled) and wifi/bluetooth off. Despite this I couldn't fix the unreasonable drain. There wasn't anything obvious in adb logcat either which suggested something was going on when disconnected from a power source.

Anyhow, I've now solved it. Overnight I got a drain from 100% to, wait for it... 98%!

Here's how to do it. First if you use Google Play Services (or the apps that rely on it) you're out of luck - so try to consider alternative apps.

Enable development mode.

Run the following in an adb shell to clear out verizon crap.

pm uninstall -k --user 0 'com.verizon.cloudsetupwizard'
pm uninstall -k --user 0 'com.verizon.mips.services'
pm uninstall -k --user 0 'com.vzw.hss.myverizon'
pm uninstall -k --user 0 'com.jrd.verizonuriintentservice'
pm uninstall -k --user 0 'com.verizon.messaging.vzmsgs'
pm uninstall -k --user 0 'com.verizon.llkagent'
pm uninstall -k --user 0 'com.vzw.apnlib'
pm uninstall -k --user 0 'com.vzw.hss.myverizon'
pm uninstall -k --user 0 'com.tcl.vzwintents'
pm uninstall -k --user 0 'com.tct.vzwwifioffload'
pm uninstall -k --user 0 'com.vzw.ecid'
pm uninstall -k --user 0 'com.vzw.easvalidation'
pm uninstall -k --user 0 'com.customermobile.preload.vzw'
pm uninstall -k --user 0 'com.vcast.mediamanager'

Then disable all the Google/Verizon apps including Google Play. You can use F-Droid to install Aurora for Google Play access without the overhead. I installed a lot of open source replacements via F-Droid like "OpenLauncher" for the home, QKSMS for messages, OsmAnd for GPS navigation at this point.

Google Play Services can't be disabled normally and this is the battery killer. I theorise there's another system app using this framework and that is actually responsible for the battery drain. Disabling Google Play Services would stop this app from running. Go to Settings -> Security & Location -> Device Administrators & disable Google Play Services. You'll now find Google Play Services can be disabled in Apps. :)

Your phone will be fairly clean at this point and you should see a massive gain in battery life, I sure have.

Cheers,

Andrew
[Android General] bensdeals:
Thanks for your post! I think this will become the most important topic, battery life. I have to say I'm also able to get amazing life without removing Google Play Services. What OS Revision (update level) are you at? I'm at 1AMD. Since the 1AMD update (I think this is the 3rd update), everything has been much better battery wise. However I'm using LifeMode, have Accubattery and Greenify, and I also close ALL apps before I power off the screen. I think you'll find prior to 1AMD update you will be racking your brain on what causes the Battery Drain. I'd sometimes get 4-5 days with minimal use, I'd sometimes get a few hours. 1AMD is much more reliable.

That being said, let's see how we can optimize without removing google play services (removal of Verizon bloatware is totally cool), as 99% of the users on here are not going to remove Google Play Services).

1. Are you using Lifemode?

2. Are you saying Google Play Services are draining the battery when the screen is off?

3. What apps are you using to monitor the battery drain.

4. Which Build Number are you using on your phone?

- Ben
[Android General] bensdeals:
Here's a screenshot of my use right now. No mods, update 1AMD
[Android General] StormSeeker1:
Guys, it's not a matter of the update, or better, they might have set something the the apps behavior to convince us that we should upgrade to 1AMD version, because (is it by casualty?...) the battery problems came at once to me and other users at the same time when Verizon released 1AMD!

Does anyone have any news from deadman96385 , who said he would have released his guide to root the phone?

https://xdaforums.com/showpost.php?p=80866785&postcount=45

Here he says: "But if i can't figure it out this week i'll release my current method so at least there will be something for people to use." on the 12th of November 2019...
[Android General] bensdeals:
I have changed nothing with my phone since the update. It absolutely has better battery life, however this is likely fixes with Lifemode or something else. I wouldn't state that the updates don't fix battery drain issues, because that is not correct.
[Android General] StormSeeker1:
WARNING! Updating to that patch probably fixes the vulnerability to the ONLY EXPLOIT CURRENTLY AVAILABLE TO ROOT THE PHONE, RENDERING THE ROOT IMPOSSIBLE!
[Android General] bensdeals:
Thats fine. Many people dont care about root. This is strictly a Battery Life thread for anyone regardless of root, not just future rooter/bootloader unlockers. this is important, as the device is still supported and updates are rolling out.

many people will get the phone at this patch/update level.
[Android General] snoopy20:
The phone continues to infuriate. I had it perfect and then last night the phone drained again from 100% to 0%. The night before it only lost 2%. I have nothing installed, it's the cleanest I can get it without root. I don't use lifemode but background data sync is off.

I'm on v2AGA-0. I'm unable to update, perhaps because I'm in the UK, though root may become important later on if the phone continues it's quirks.

Palm support is non existent.
[Android General] snoopy20:
N/A, unable to delete.
[Android General] snoopy20:
Another night of spectacularly low usage, woke up and still on 100%! Not realistic but the algorithm will be taking into consideration the high usage of the night before. I better not touch anything now.
[Android General] snoopy20:
Still looking good. I have confirmed one problem area though.

If you're using the phone for USB tethering and put the pc/laptop to sleep it will probably reset the enumeration into power only mode. When tethering the phone doesn't reconnect into power only mode and causes a serious power drain (about 15% per hour). I've no idea why but it's consistent and maybe this is why they hid the tethering support. Be sure to unplug the phone or disable tethering before putting the pc/laptop into standby.
[Android General] pithanks:
Seems mine gets stabilized after wiping cache partition in recovery mode. 8-10% loss overnight now. It was more than 80% loss due to cell standby process.
[Android General] tapa_t:
I've got a question for you -

In Accubattery, "Health" tab, what mAh does it say for the "Designed capacith"?

And, what does it say for the "Estimated capacity"?
[Android General] grimez:
Just used your list to remove the bloat, but the "pm uninstall -k --user 0 'com.vzw.hss.myverizon'" command failed. I can see it and disable it still, just not sure what user it's installed for after the latest update.
[Android General] g60madman:
One more app you can remove is the Verizon Location Agent, specially if you are not on Verizon.

package:/vendor/priv-app/Verizon_LocationAgent_vzw_v0.0.3.120_Production_NoDebug_release_signed.apk=com.telecomsys.directedsms.android.SCG

To uninstall run this in adb shell

pm uninstall -k --user 0 'com.telecomsys.directedsms.android.SCG'
[Android General] g60madman:
So after removing all the VZW apps the phone is still eating the battery like pac-man. This morning I woke up and the phone was at 32% after leaving it charged to 100% right before I went to sleep (10pm-5:30am typically). After checking the battery I am seeing the following eating up the battery ”Mobile Network Standby” for 66% and system and apps were 1% each. This is completely unsatisfactory, but also a bug with Oreo. For the record I am running stock right now and also using the 2AGG version of the ROM with Straight Talk carrier.

I have configured the following settings to see if this helps at all and will report back.

Setting #1

Settings --> Security location --> Location (under Privacy) --> Scanning. I then disabled both Wi-Fi- and bluetooth scanning.

Setting #2

Enable Developer Options and then un-checked Mobile data always active.

UPDATE: So after making those changes the device has been idle for 10h 52m and it's at 80%. It as has dropped 17%for the Cellular network standby and 1% for apps. It's showing the phone can be idle for another 2 days left which is much more respectable. I think these settings accompanied by removing the VZW apps makes this a closer to daily driver for sure. I hope this post was helpful to others on the board. I will be spending my time now on development on the device starting with looking at the source code that was released by Palm. I will be creating a new post once I make some head way.
[Android General] snoopy20:
Mine has gone back to terrible. Although I have mobile data on I'm using very little of it. While on a cycle ride I lost 45% in 4hrs.

I suspect the battery has had it.
[Android General] al07th:
I have got pretty random stats: sometimes it 5% per night, or 12%. Last day i got 50% discharge during 3 hours afk on the table (every app was closed).

So it's not might be a battery. Try out AccuBattery for a few days to check charge\discharge rates and cappasity.

There can be a problem with the firmware itself I imagine.
[Android General] snoopy20:
I've ran Accubattery and there's nothing running. My suspicion is is Android isn't working out the % properly as it's based on the charge capacity over time. Degraded batteries don't have a linear discharge rate.

Palm support got back to me, recommended a Morph Juice battery. Useless as always.
[Android General] bensdeals:
What % wear do you have under health in accubattery?
[Android General] rupintart:
Whenever I try to enter in a line of code I get an error: https://imgur.com/gallery/1rHO8xE

Hello together,

it's been a while and I wonder if you have found a solution to get a better battery life in the meantime?

I really want to buy a PALM Phone but I am afraid of the bad battery performance. Have you fixed anything?

Please let me know. Thanks.
[Android General] nikolawolf69:
I just did it and noticed it doesnt remove all Verizon stuff. I have an US palm using in Germany and when I put in my sim card I get the message that the sim is not from verizon wireless (but its not locked as I can do calls with the german sim, at least sometimes).
[Android General] nikolawolf69:
Well, while I cant really use the phone (trying to make an US phone useable in Germany) I can at least say that this battery fix really works. The battery life is pretty amazing since a few days. Super easy to go through a day.
