Touchscreen issue (bad grounding)

When I put the device on to any insulating surface such as pillow/bed/couch/table I cannot normally operate it. Touch is being interrupted very frequently. This means in practice that I unintentionally press links while sliding through web pages, it is impossible to organize icons (since icon is dropped quickly), pinch-zoom is difficult, unlocking the device is hard, when text-typing it often doubles the letters etc.
Problems goes away as soon as I plug the charger, or take the device in my hand. This looks to me like a grounding issue, which was annoyingly present in some of OnePlus One and Nexus 7 devices in the past. Desperate users were hoping for a software update to solve the issue but it never came out.
Is anyone else experiencing similar problems with Mi 4c? I also tried flashing different MIUI versions, nothing helped.
Here is a video demonstrating the issue (you can enter hardware test menu by calling *#*#64663#*#* and try it by yourself):

I tested, mine is ok

I never really use my phone that way but out of curiosity, I tested it. Can confirm, issue is there. Touch screen goes crazy when scrolling facebook posts, chrome browser, possibly anywhere until I lift the phone up.
Just noticed that I needed to tap and scroll up/down harder than I used to otherwise I would miss it and the scroll would stop halfway through and will tap on whatever it is on the screen when it stopped.
Basically when I don't tap hard enough when doing the scrolling gesture, that's the time that the touchscreen goes crazy

works proper at my mi4c

I had the exact same problem. It is a defective screen. The problem started appear for me after 3 days of use, so I returned it to the store for an immediate exchange. I am not sure if you are in China or not, but if you are, you can just walk into the store and get a new one on the spot.

for me works perfect

Works ok on mine

Works fine here...

I can't even get the touch test started, running cm12.1, dailing *#*#*2664#*#*does nothing, as well as no other I've tried tested

Try it with some app. For a single-touch this one is just fine: play.google.com/store/apps/details?id=com.tsaysoft.touchtest
It draws a continous line and if you lift a finger (or if you have faulty screen) the line disappears.
To test a multitouch function you can play with: play.google.com/store/apps/details?id=com.the511plus.MultiTouchTester

Mine is working as expected as well

found solution(the grounding problem is still a thing but this makes it less of an ass)
1) root the phone or just use the developer rom from xiaomi
2)then install Pimp my Rom from google play and grand root
3)go to tweaks-> touch-screen & display-> multi touch amount
and put it on 5.

Hello,
Yes. As a proud owner of one (unfortunately defunct cause I dropped) nexus 7 2013 I can confirm that the behavior is the same... Definitely a grounding problem.
When you leave the phone on a pillow or couch without holding it,bthe screen response is erratic. When you hold it or attach charger.. No problem.
Still beautiful device (the 4c), especially for the price. Snappy.
And smiu is very good made. (not a fan of miui roms...)

This happens only on 16gb version? What about using a plastic case? Does it solve the issue?

I have the same issue. And I don't know how to solve it. Except without gestures.

I have full screen gestures enabled and no issues with swiftkey(beta). On what rom are you? I tested it with chinese stable and xiaomi.eu

Doesn't matter if I push the letters or just swipe, no lag at all. Maybe you can test the swiftkey beta app or disable spellchecking in input settings

Hello again
If I disable de voice comand, the problem persist.
I downloaded the beta and, the problem is the dame.
I Dont understand. If I disable the full screen mode, its solve the problem
Im not alone with this problem

Sent from my Mi MIX 2S using Tapatalk

I'm using this phone since three days ago and I immediately noticed this issue, and it is specially annoying when I try to use swipe writing. I suspected that occurs because the system doesn't know if your are trying to write using the keys located at the edges of the screen like q, p, etc. or just using gestures. In consequence I tried to adapt the keyboard using the one hand feature (Google keyboard) and putting it in the center of the screen and it worked, the lag disappear. I'm attaching a screenshot because my English sucks. I hope you can see this way what I did.

I tried turning on 'Show virtual keyboard' in Settings > Languages & input > Physical keyboard, and it seems much better for me now.

I have the same problem. It seems that there are many of us who have this problem. I hope that in MIUI 10 they solve it ... I can not find any solution, just turn off Fullscreen mode in my RM5

I have already reported to MIUI team but while they do something about it, i've installed Edge Gestures to replace full screen mode, to hide navbar i've installed Navigation Gestures and finally AutoNotification for hidding apps in background notification. I have lost gestures animations but works perfect and the only issue it's volume bar in landscape like the image attached.

This is a nightmare and makes the device horrible to use.
I reported it to MIUI team weeks ago. The best solution for now is disable vibration on keypress within Google Keyboard, which makes it way less noticeable.

I'm using miui 10 weekly on eu roms, the problem is still there...

I'm on xiaomi.eu 8.8.3 and it seems like it has been solved through software update. I no longer have the issue testing in sketch app, or using any keyboard with full screen gestures.

Multitouch/screen issue ?

Hi there,
I just received my new Mi MIX 2S (actually, I got it 360 hours ago, if you know what I mean...) and I'm very satisfied with this toy
I'm on the last MIUI 10 Global Beta (8.7.5) since this afternoon, with SuperSU v2.82-SR5 and of course, with an unlocked bootloader.
However, I noticed a "strange" glitch/issue when I quick touching/typing.
It's seems that the screen not considering the different touch but acts like it does "two in one" touch.
I made a small video to illustrate the issue :
https://youtu.be/NdW8Zeo1MLQ
Does anyone has this too ?
Do you think it's an hardware or a software issue (like calibrate or touch-delay update) ?
Thanks

Damn... I bought mine on Joybuy, I'll try to deal with them about the warranty because I guess I can't contact Xiaomi directly.
The XDA Gesture workaround seems to be a good temporary way but, I really don't want to stay on a defective device...
I already did this with my Oneplus One (as a early buyer, I got a similar issue) and it was worst with time, I regret to had never return them

Bought mine on Aliexpress, no way I'll get a warranty without me paying $30 of shipping and lose a month without the phone.
I tried the XDA gesture thing, but you can't really get the same gestures as on MIUI (alsway have to make the gestures from the bottom of the phone it seems). So for now I'm just using it with this "bug", with the keyboard closing from time to time when I type.
Probably gonna get a Mi Max 3 to replace it anyway sooner or later.

I just made the thest you did with a drawing app and I got the same results when I multi touched the screen very quickly. I hadn't noticed this earlier because it didn't cause any problem for my daily use. Specifically, in which context did you notice that issue?

Thanks for your test and your answer.
In my case, it's very annoying when I (fast) typing a message, it causes a "fake" swipe and recude the keyboard or go back to home screen. I'll try to make a better screencast to show you in-use case.

Fine, I'll tell you my experience. I use to had the same problem, it's only noticeable using the keyboard and specially when you tap the letters located near the edge of the screen, specially like the Q and P. I'm almost completely sure that the problem is related to gestures, because the system thinks you're swiping, in my case I got some lag too in addition to the false back gesture. What I did to fix this is use the keyboard (Google keyboard) in one hand mode (long press the "," and this option will pop up next to the emoticon) and moving it to the center and the problem is gone. It's actually more comfortable this way because the space bar moves up and it's more accessible. You can play then with the keyboard size if you think it's too small. There are two others threads talking about the same problem and I recommended this solution in both, and it seems to work for others too. Try it and tell us.

Hi,
Actually, I think it's more an OS issue than an hardware one.
After some tries and research, I noticed that these "screen glitches" are bad interpretations of fast multitouching, translate into swipe/gesture.
These swipe/gesture come with the gesture navigation mode, included in full-screen desplay (and which allow to hide the bottom navigation bar).
If you re-enable the "classic" display, with the bottom bar, the issue doesn't seem to exist. So, I guess for MIUI, some fast-typing/touching are interpreted as gestures (swipe down-to-up = home, left-to-right = previous...)
In the same registry, I noticed that, if you use a scrollable widget (Google Agenda in planning display) and if you scroll down on it (in order to see the bottom lines for example), MIUI interpret it as a down-to-up gesture (and so, go back to home, or search).
So, I really hope that in a future update, the sensibility of these gestures could be decreased/improved...
For now, you could :
Enable the one-hand mode ok Google Keyboard as proposed by @rodaven (but personnaly, I dislike the fact to have a small keyboard with a lot of lost space around it...)
Disable the full sceen display mode (and so, say goodbye to the gestures feature)
Stay on full screen mode and gestures, get upset when you write a message and pray for un update

I have the gestures disabled because of that but it still happens in the keyboard (I don't like the one-hand mode). So, we need to wait hoping it'll be solved.

In my opinion, it's the same issue.
Due to the full screen/gesture feature, fast multitouches are interpreted as a gesture.
On my video, you could see it.
On the issue from MIUI website, users asked that swipe/gesture are disable over keyboard when it's on-screen.
I think it should be a solution to combine gesture navigation and fast multitouch/type.
Personnaly, I disable full screen/gesture navigation (for now, sadly) and the issue desappear, that's why I'm pretty sure it's a software issue (which concern very model with this feature).

I changed my screen
Actually i cracked my screen and replaced new lcd from aliexpress claimed original. I checked it is JDI. But the touch issues still persist. I think its xiaomi driver.. or i dont know.. i really regret having this phone

It's very disapointing, I had touch screen problems with my oneplus one and now with the mix 2s.

Touchscreen insensitive

I've noticed the touchscreen is a little bit slow/lazy when I activate navigation gestures.
The lazy response area is only on the bottom-left of the display, and it concerns only the "A" letter of my qwerty keyboard (a very small area).
This lazy response of the touchscreen is on all other apps, not only in the keyboard, and it concerns only that small area.
If I use navigation buttons, the problem disappear.
I don't know if this issue was present also in previous OS version because I've tried using navigation gestures today
I've the Nex S 8/256GB, PD1805_A_1.17.10
Anyone noticed this?

Exactly the same here...
Sorry for this (maybe too) late answer: Have exactly the same issue. I'm used to write really fast on my phone, but since having the Vivo Nex, I'm slowed down extreamly because of this. Also for me just the "A" letter is the problem. Doesn't matter which keyboard or size (tried several), it's always laggy...
I really hoped this would be a thing of the past after the newest "Funtouch-update" from some days ago, as they've been writing about "better touchscreen accuracy" in the changelog... But nobchanges at all concerning this point...
Did anyone already found a solution against this, without having to turn on those ugly navigation buttons on the bottom of the screen? I really like the three swiping gestures.

Same on my side
Seems as my previous post has been deleted / went lost...
I've exactly the same problem here with the "A" key of the keyboard being really slow on my Vivo Nex S (256GB, global version). Hoped this problem would fade away after the newest "Funtouch" update 3 days ago, because they wanted to have solved exactly this problem, what Vivo told us in the changelog...
But all kept the same. Tried already three different keyboards with different settings, no success. Does someone has a solution for this?
But I really DON'T like having the navigation buttons visible, so this is no option for me. I definitely want to use the original slide actions for the three buttons below the screen...
To be honest: I'm using the Nova Launcher over the Funtouch System (the Funtouch launcher is absolutely useless). Could this have an influence?

This happends to me too.It seems there s area down to the bottom of screen is not sensitive enough.
I have vivo 1805 which is Taiwan version, not sure if this model same as the global version. And I also try to flash the chinese version ROM but failed cause of the signature difference. The update progress in Taiwan is not as fast as chinese. Hope VIVO in Taiwan could release the fix soon.

Well, not sure if this is the same issue on my device, as the sensitivity seems to be ok on mine, but I have to push the "a" button much longer (not stronger) than all others. So just a laggy key... And REALLY annoying!
But "good" to hear that others seem to have comparable problems. If there just finally would be a fix for this on the Vivo phones...?

Hey guys. I have been facing the same issue and started experimenting with navigation replacements. So as you guys realize, sensitivity is just fine when using the nav buttons but there are a lot of keyboard mistypes when using Vivo's own navigation gestures.
Therefore, after expermintation, I can confirm that the app called "Fluid Navigation" is an awesome replacement for the navigtion gestures. XDA Navigation gestures is slightly incompatible with the Nex. But Fluid Navigation works perfect.
So all you need to do is follow these steps
1, Switch to Nav buttons
2, Install the app
3, Grant accessibility permission
4, Grant Write Secure Settings through ADB. The app gives instructions for this
5, Hide the nav bar through the app
6, Customize the gestures in the app. It even allows quick settings swipe up.
Hope this helps. Enjoy guys. You will definitely feel the difference

Question Missed characters during typing on S22 ultra? (Erratic key character behavior)

Hello guys,
I have tried with default Samsung Keyboard and tried with Swiftkey and noticed that when I am typing certain words like "Allergy" or "Where" for example, it suddenly interrupts the swipe pattern and changes the word to "All" with space next to it as if there was an error registering the touch gesture as I touch each key on the keyboard. It seems that this happens a lot near the letter G.
This does not happen on my S21 ultra. Tried without screen protector, and same issue so its not the protector. Tried *#0*# and did a display Touch test and it registered everything perfectly. Tried clearing cache/data no luck. Tried disabling/enabling auto correct and no luck either.
Does anyone have this erratic typing issue?

Hello mate, yes I also have this issue, on any of the keyboard, I tried Samsung stock keyboard, gboard, microsoft keyboard, some other mates are also experiencing this issue in Yandex keyboard.

maybe you can use google translate, but this is russian forum https://4pda.to/forum/index.php?showtopic=1029360&st=4120#entry114129735 here is the example

also another mate already reported the problem to the samsung members and they acknowledged it
Samsung SM-S908B Galaxy S22 Ultra - Обсуждение - 4PDA
Samsung SM-S908B Galaxy S22 Ultra - Обсуждение, Смартфон, 6.8
4pda.to

It is a feature, the new text prediction is by GRAMMARLY, but like in this forum, doesn't work well and the cursor goes crazy.
Solution, TURN OFF PREDICTIVE TEXT.

nah, disabling predictive text does not help.

Exactly same issue on S22U exynos! Very, very annoying.

Any other better alternative keyboard ?

the only solution here is not to use swipe feature of the keyboard, as this issue appears on ANY keyboards (personally tested).
I would suggest Fleksy, as it is designed to type manually, and wait for a fix of this problem.
personally, it is one of the serious reasons to sell this phone (sadly)...

There's a thread in the Samsung members app about the same exact thing, it started with the April update. I haven't gotten the May update yet, I'm hoping it will fix it but I don't have that high of hopes. It's definitely a software bug though.

Did anyone try to rollback to a March firmware?
Also, if someone received May update, could someone confirm that issue is resolved?
Thanks

it is NOT fixed, yet...

UP.
Seems like swype is fixed with the newest update S908BXXU2AVEH.
I'm currently on it and checking that everything is good.
Can someone confirm that?

I've experienced the same wonkiness described by the OP with SwiftKey on both my S22 Ultra and Tab S7. In fact it happened while typing this on my Tab S7. I'm not able to consistently replicate it though. Or at least not able to purposely replicate it.

Okay so I've been experiencing this same issue and this is everything I've found so far.
The issue is when swype typing on any keyboard. I enabled touch pointer in dev options to see exactly what was going on the screen and what's happening is for example when swype typing the word "everything" the screen recognizes when touch the E and begin moving towards the V but it loses the touch and detects it again so it thinks you finished typing a word and started again therefore the word EV is put on the screen and a new word is started. This is very aggravating. I've noticed that it happens a lot with words starting with E, A, W, S and if you notice those are all in the same area of the keyboard.
What I've done to fix it. I use film screen protectors instead of glass. I thought the SP were too thick and it was messing with the touch sensitivity but i tried several and nothing changed. I tried various settings in the phone especially the touch sensitivity option for screen protectors and turning it on definitely helped but the issue remained.
What i did was take the screen protector off completely, leave the touch sensitivity option enabled in settings and the issue is completely gone. So the issue lies somewhere with the sensitivity of the screen and screen protectors limiting the touch sensitivity.
This is all I've got so maybe this info will help anyone having the same issues. Hopefully Samsung will adjust the sensitivity in upcoming updates.

No worries, mates
This issue was fixed with June update
I have already installed it, running for 3 days, everything is working great, no problems with swipe typing
S908BXXU2AVEH

I can confirm also that the issue was fixed in the latest update.
