Ghost touch mi3 - Mi 3 Q&A, Help & Troubleshooting

i m experiencing random or ghost touches on my mi3 .
Things i have tried:
1: Reboot solves the problem for some time ( enough to sell it )
2: Removed tempered glass still problem continues
3: changed roms and flashed stock fastboot rom still problem continues
Help me ......

Does this happen after you charge your device ? Or using it while charging ?
Charger supplied with mi3 leaves static current on screen.. Change your charger.. Calibrated your screen by going in hardware test option.. It will become normal..

[Q] Any touchscreen issues?

Guys i read on some forums that Mi3 has touch problems like over touch sensitivity and many users are facing it...is there any user here who facing it or it's an hoax? I have ordered one yesterday and i am worried about it..i was fed up of touch on my old phones..please help
I am also experiencing this touchscreen sensitivity issue. Even just hovering my finger on the screen it already responds. Glove mode is off, even tried it while its on, still the same. Did a calibration, no effect. Anyways, it just causes some accidental touches but it does not mess up the entire experience.

its a myth or because of a faulty device.
if it occurs only while charging then it can be the power socket that you are using. (usually occurs if your phone i still plugged in after it has been fully charged. happened on my s3, galaxy s duos and grand duos as well)
could be because of using local charger, faulty battery, basically anything that can mess up the voltage and interfere with the touch screen (but only while charging) very rare chance almost one in a million that somehow a faulty battery causing this.
no such problem on my dad' Mi3 and i ordered it during the first flash sale of Mi3 in India. no issue or problems in the phone so far.

I am having this issue of mis-touches while charging.
I touch somewhere and it actually gets touched somewhere else.
Using latest stable rom v23 (India) and using stock charger.
What can I do to solve this? Take a replacement of phone or the charger?

you can try different charger and different power socket which will eliminate faulty charger, cable or irregular power supply. if even after testing all this you still have problem better take it to nearest service centre because if its battery's fault let the service centre guys take care of it. don't do anything that may void warranty.

I have tested it with my Note2 stock charger and it still has same issues.
Still will test it out for some days and then decide.
By the way the phone is not one month old so should I take a replacement from flipkart? Or go to a service center?

Go for a replacement. drop an email right now before 30days time period is over. If you are facing this issue only while charging then there is very low chance of it being device fault.

It is a battery fault I think but since the battery is non removable can't do much.
Is your charging point earthed properly.. Mis touch problem is caused due to improper earthing
hum does it have touchscreen problems?
i mean like the ONEPLUSONE?
if so i don't want it. i mean i didnt chois the oneplusone cause off that. my screen has to work 100% fine or i'm going mad

Yes it is earthed properly coz the others phones charge without any issues. I even checked the charger. Its all fine.
I had ghost touch problems when USB charging from my laptop...it was cuz I'm using a third-party charger for my LAPTOP charger...when I remove the laptop from AC power, no ghost touch...
So basically, I doubt there is any problem with the device itself (except for the fact that it is so sensitive to improper charging unlike other devices) but I don't think getting a replacement will help. Just use the supplied charger, on a properly earthed socket.
I had this same touch problem. Actually the problem is that the touch misses. What I mean by that is, draw a straight line from one end to another and in between the touch misses and you get a broken line at many points. I cheked it using the Hardware Test function and going into "Touch screen Test". Start to draw a line and see what happens. It will miss after every 1 sec or so.
So, i tried to find the cause. And i came to know it mostly happened when the phone was put on charging and mostly made the phone unusable while charging. It also occured after taking the phone off the charging if it was overcharged. So I used charger of Samsung Note 3 and voila. The problem is gone.
Summary : Charger supplied with Mi3 is piece of s#it. Dont use it. It will damage the screen with static charge that is left on the screen after charging. Get yourself another good quality charger.
I have noticed this problem. There is touch input even while hovering finger about 3 mm above the screen. I don't mind this problem that much but it does become a minor annoyance sometimes while typing. I don't want to apply for a replacement though as the phone is flawless otherwise and I've heard that even the replacements also have the same problem. I have not yet removed the protective screen cover which comes with the phone so I don't know whether that's causing the issue.
Update: I have applied a tempered glass screen protector and the problem is still present.

I noticed yet another problem. The multi-touch is OK for about 4-5 fingers. But above 5 fingers, the touch gets haywire. Ghost touches, touches not getting registered, touch points swapping, etc start to happen very badly. Is anyone else facing this issue? I tested using antutu benchmark.

Sadly i experience the same issue. The screen gets hypersensitive from time to time. I've had my MI3 only for a week now. Considering doing a factory reset. Any experience?

Go to hardware testing and then to touch sensor and hit menu button and calibrate
My mi3 touchscreen is fully working after 7 months (and i hope even in the future).
Hi,
If you are experiencing serious issues like miss typing and random unwanted button pressing by the phone then this is for you! I recently woke up and found my phone spazing out and not being able slide the screen up properly. So this is what worked for me and hopefully will fix your issues too!
1. Install any updates that need doing. Restart phone.
2. Still have problems then turn off glove mode ( settings and then display) and clear and wipe cache. Do this by holding down the up volume key on the side and power button - wait until the screen goes black and then it should appear in recovery mode. Use volume buttons to select the language and the power button to enter. Go Wipe and Reset and then Wipe Cache. See if that works. If it doesn't please look at Step 3.
3. Now try refiguring and calibrating the touch screen through the hardware menu. This was painful for me as all the buttons i wanted to press hit another key! but eventually got it. Try to key this into the phones key pad and call: *#*#64663#*#*
4. You are now at the hardware menu. Find touch screen and then the black screen appears where you can your finger over and draw. Use the button next the home button to get the start calibration menu ( looks like this 三)
and then hit start calibrating and wait for it to work. I actually need to go into setting to change button layout as only apps appeared when i pressed there....
This then solved all the issues and my phone now works perfectly
Let me know if it worked for you!

Touch problem while charging.

I am encountering a problem from a few days.
My touchscreen doesn't work while its charging.i think first found it while picking up a call when it was connected to the charger.
It doesn't work even after removing charger,i have to turn the screen off and then on,then touch works,but not fluently.
But it works fine after rebooting.
Anyone else having this problem?I am on stock 6.7.1.0 build(latest one).

I get ghost touches when I'm charging. I notice this is most when using the stock charger that came with the box
Ghost Touches
With the original charger I had ghost touch too... I bought a new charger a bit more efficient than stock and it's all ok
Try to change your charger and tell what's your result:laugh:
I have this issue with A110 from Micromax not with MI3

Mi3W TouchScreen issue

From yesterday I was having a strange issue with my Mi3w, I'm using this phone for a very long time. I have noticed that, a small part of the screen is not responsive. If I want to swipe my lock screen up, then a certain point the touch does not respond. more over the device is not also responding if I reboot my device al least 3 min, after that the screen become responsive again, with recovery mode the issue is there, it does response after couple of minutes. I'm not quite sure what the issue. It's not a ROM issue I guess because I've flashed a MIUI 7 ROM and it's the same issue. Could it be possible that the LCD connector got loosened up somehow?
Take a touch screen test using *#*#64663#*#*
You wont even believe what i had been going thru
I had the same issue on my mi3 due to which i made a decision to test out a custom rom.
it was little strange for me n let me explain :
While i was using Miui ROM , My phone started going into "Button Non-responsive" mode
While trying to find the cause i realized it was sue to heating on near just above area right in center where board is placed
Non button responsive mode means : Recents app will open, I can still use screen but i cannot use any buttons (hardware/Software based)
I am currently on RR current version : i still get recents open up or G Shortcut open the menu but i can use button (Thanks Custom Roms)
Did you recently faced any liquid/wetting issue on phone ?, if not, still get the phone opened up & get the cleaned up.
Try changing the protection glass or smthing installed or use it naked
Try touching your phone to metal rod where you can static discharge
Cannot comment much as yu are facing issues in receovery too but still try & report
No liquid damage that is for 100% sure. Check the screen test snapshot from here. http://tinypic.com/m/jgs5zb/1 Between those two line touch is not responsive. As I have mentioned that Device is in non responsive mode after reboot and even in recovery mode after couple of minutes. One reapair guys said that the digitizer has doomed. You wont believe the quoted price from 1 of 3 service center here in kolkata 5800 INR, 2 of 3 said, they don't have the parts and company stopped sending the item, please get the work done via local technician, 3 of 3 said, quoted price is around 6800 INR. My best bet is Ebay. BTW do you still have the issue?
Well I do have the issue but my phone is working fine otherwise
buy from Ebay & it should cost you around 1500-1800 only including fittings.
Try it & i might buy a new screen+digitizer too !!!
Going to buy a original one? BTW here is a Ebay search result. Suggest me one.

mi5 black screen issues

Recieved my mi5 yesterday and used it for about 15-20 minutes (just playing around with MIUI), turned the screen on and off multiple times but suddenly the screen wouldn't turn back on I rebooted the phone (hold power button) but nothing happend when turning it back on.
the capacative buttons and charging LED works as well as volume up and down (I can hear the volume change sound). After about 4 hours it suddenly worked again and I thought it was fixed (it was not), I booted into fastboot and unlocked my device but when I try to turn it back on the screen was dark again, and after several hours it still doesn't work.
There are other people with the same problems but I don't think anyone has been able to fix it.
Has anyone else encountered this? If so, did you fix it? I thought I'd should mention it anyway.
same problem..no FIX !!
Few months ago I also received a 32gb device and had exactly the same issues you mentioned. First with MIUI and locked bootloader, then unlocked and tried 3 different Rom's, MIUI 7, 8 and Lineage OS. No difference.
IMHO a common hardware issue on some devices, mine has a LGD Display. Meanwhile I got another one, which is working fine, but have this faulty one still here, for spare parts right now
Would help if someone could state whether this issue is screen or motherboard related, so I could maybe replace parts and use or sell.
Sometimes it went completely off, no capacitive buttons, no volume sound, no reboot possible. But battery not empty. Had to disconnect battery or wait one night until it would respond again.
Also observed less black screens in warm surroundings, had more problems being outside in winter.
yesterday my mi5 died with this problem...
hope the warranty over tradingshenzhen works fine...

Want to share following with people who experienced also blackscreen issues with Mi5:
lately needed an identical Mi5 device to recover some apps from another device and decided to try with this "damaged" one from last year. Fastboot flashed Miui9, then wiped, installed latest TWRP and LineageOS 15.1. Did my backup/recover tasks. Then I just kept using the phone, because I was curious how long it takes until the blackscreen issues would appear but they didn't.
Device is working without any screen issues now since a week or so Seems like new firmware has fixed something, at least for my device.

same here, i tried almost every ROMs from Android 6 (CM/MIUI/ASOP) to Android 7.xx (MIUI China, and RR...)
The touch screen will suddenly have no response until i force rebooting the phone.
However, it seems hardware-related issue, i had found the touch not work while entering TWRP (the ROM is not loaded yet).
Next step, i will try to teardown it and re-assemble to see the method works or not.

hi, i tried to teardown my phone and re-connect all connectors, but the touch screen will still be no response after a while.
does anyone have any other idea?
Its probably hardware problem, as i don't stay long enough in recovery to notice the issue or unable to notice it because all you do is press and not a lot of swipes, and another problem is that its almost impossible to buy a new original oem screen,all those sellers on aliexpress claiming to sell new screens in reality just sell a refurbished screen with very low quality, it looks like the old saying "if its made in china its
sh*it" is true, yes most phones are Chinese but they are older companies, better engineering, more experienced, yes issues like this also happen with them but a lot rarer, but here it looks like 10%off all sold phones have problem, some same as ours some worst, and i was typing this for so long, i try to type one letter, another one is pressed or none at all ?
Have you tried flashing Stock ROM ? If you don't then please give try.
earlier versions of TWRP had this issue but only in TWRP. Now it's fixed. And some devices doesn't support such custom kernel and causes problem with nav button.
So first flash thw stock rom and see if the problem exist or not.

I am currently on stock global beta firmware and still facing the same issue, no root not costume recovery and still facing the same issue, now i almost sure that its a hardware problem, like many other users that face it ?
Okay you can post this one to MIUI forum. Try submitting an issue there. Hope you'd get some solution.
I don't think there is another solution other than changing the screen, but thanks anyway
i thing this is the hardware issue, anybody can detect the problem?

While the touch screen lose response, you can press middle part of mi5 (i.e. the connector) vigorously without shutdown the phone. And then, you can find the touch screen will work again. Therefore, in my case, that indeed a hardware issue.
FYR

Can you explain this better? I have the same issue, if there's a way to fix it without reboot I want to try it, but I don't understand where/what I should "vigorously press"...
For your reference.
I had touchscreen problem at the beginning when I received it from Gearbest in 2016. It would take much time to send it back and forth so I decided to flash it with a newer Global stable rom (I think I was Miui7) by myself; after that, the problem was 95% gone, (it still happened sometimes but not severe). Lately, I cable updated it to Miui 9 Global Stable and the problem was back and severe.
I TWRP installed Miui 9 Global developer Rom - not working
TWRP LineageOS 14.1 - not working
There are no points to use LineageOS 14.1 if the touchscreen problem is still there.
So I TWRP cleared data and cable-installed Miui 9 developer Rom, and The problem is completely GONE!!!!
Maybe you could try some of the steps above.
I also change my charger from 2V to 1V output after installing, and only charge it from the wall socket. (I used to charge from the extension ones more)
I only installed necessary apps at the beginning then gradually add more.
Hope that would help!!
