Hello,

I'm suffering from the very same issue. I've had the phone since roughly the middle of May. The problems started a few weeks ago and has persisted and has even exacerbated during this time.

I've tried multiple roms; mi.eu, ROS and now currently Pixel Experience and the problems persist between installs. Curious thing is though that during the first few days after a clean rom install/reset the problems are nonexistent and then get progressively worse and worse.

Ive tried the Mi touch test using *#*#64663#*#* and have alot of ghost touching in the top of the panel and sometimes stretching further down the screen. The problems are intermittent and sometimes it can go hours between ghost touches and sometimes the phone is totally unusable ie you can't write anything due to notification bar gets pulled down all the time, the touching simulates a double tap on notification bar and causes a screen shutdown. But overall the problems increase in severity as time goes by, as mentioned above.

What I can't confirm is whether the issue is connected to using certain firmware/miui version. I never used the Mi 9 when I had official global stable installed and therefore can't confirm if the official firmware has this issue also.

Gboard seems to make things worse funnily enough and switching to SwiftKey can help a bit. My BL is unlocked and I have no warranty left so if this continues I'll have to buy a new phone.

Anyone fixed the problem? I've been having this for almost 3 weeks now and my phone is almost unusable.

I'm on weekly and tried all Roms of the last 3 months and after each install it works perfectly fine for a few days and then ghost touch starts and I'm having a hard time not throwing it against a wall. Wiping cache and Dalvik also works some times.

I had the same issue on my Mi 9 SE. Apparently, this is a hardware problem.

But there is a workaround to this, so if anyone encounters the same issue, try the following:

1. Open settings
2. Additional settings
3. Open "Language & Input"
4. Open "pointer speed" (at the very bottom)
5. Turn it down to the minimum.

This will decrease the touch sensitivity and it worked for me. Maybe you don't even to turn it down completely, just try out something that will work for you.

Regards

Alright, this seemed to be a temporary fix, since the issue reocurred after a few days. But i found something new, which seems very promising. So try the following:

1. Open settings
2. Activate developer options (My device > Tap 8 times on "MIUI-Version")
3. Settings > Additional Settings
4. Developer options
5. Disable MIUI-Optimizations (at the very bottom).
6. Reboot

This will also disable some other features of MIUI. But for now, it really did fix the issue for me. There are many reports that suggest to turn off the three finger swipe for screenshot, but that alone didn't do the trick for me. But the new settings seem to help.
