[Xiaomi Poco F1 Questions & Answers] ipdev:
I may have flashed it once or twice last night. ;)

I did not run into problems but, most of my testing was done starting with a clean flash and quick updating from there.

crDroid, Validus and pe_caf

I am currently running crDroid

6.10 vendor, firmware and kernel.

Magisk-debug (Canary), SimpleGapps plus google keyboard.

Yes I still have random ghost touch.

Uptime was 19Hr. 50 Min.

Currently trying a few things so I have been rebooting a few times since.

Just remember full backups are your friend.

If you can, copy everything (at least the stuff you are not willing to lose) somewhere else.

Computer, USB drive, sdcard.. Somewhere other than the internal storage.

There are a lot of ways to try and recover if something goes wrong.

If you prepare to fail you probably will succeed. :silly:

When I test.

I make a complete backup using the official TWRP.

adb pull /sdcard to my computer.

Format, wipe and flash the f*ck out of my Poco.

When I am done testing.

1. Flash firmware (If need be)

2. Flash vendor (If need be)

2.1. Remove forced encryption (If need be)

3. Format and wipe everything.

4a. adb push sdcard/* back to /sdcard/

4b. Restore userdata from back up.

5. Flash rom

5.1. Flash GApps if not included in rom.

6. Flash Magisk

7. Flash kernel

8. Reboot

Note:

4a and 4b might need to be reversed or done a second time depending on the outcome.

I may have to clear cache and/or storage on one or two apps.

Even though I remove the lock screen pin/fingerprint before making the backup.

Normally I have to delete a leftover gatekeeper or locksettings file from /data/system/ before I can set a new pin or pin/fingerprint.

Too bad to hear that still 9.6.10 didnt fix the ghost touches, i would remain on 9.6.3 for that matter, as a matter of a fact i dirty flashed 9.6.10 over 9.6.3 and had a black screen after booting up to system, so I had to revert back to 9.6.3 its really a shame that miui haven't got a fix to this touch screen issues which seem to me that its more of a rocket science to such company.
[Xiaomi Poco F1 Questions & Answers] :
always clean flash vendor
[Xiaomi Poco F1 Questions & Answers] droidjunky90:
Are you on latest 9.6.10? If so are you experiencing any touch freezes / ghost touches?

I don't get screen freezes from MIUI. I only get screen freeze on custom roms. Does that mean that mine isn't hardware issue but just a firmware one?

Apparently, my custom rom screen freeze just appeared after 3 months of using a custom rom. But MIUI never gives me screen freeze.
[Xiaomi Poco F1 Questions & Answers] :
yes.9.6.10....no ghost touch on my LOS
[Xiaomi Poco F1 Questions & Answers] MrSchaal:
Same happened to me today. I'm so happy that reverting to 9.6.3. was possible without any problems or wiping. Just reflashed 9.6.3. again.
[Xiaomi Poco F1 Questions & Answers] ele95:
Yes I think it's only software issue not hardware and you need to use miui kernel on custom ROMs to not get any touch freeze I didint got any since April
[Xiaomi Poco F1 Questions & Answers] Nova3einOz:
Any chance of a link for the 9.6.3 kernel?

Have you had any ghost touches / screen freezes before 9.6.10? If so, did 9.6.10 completely solved the ghost touches and screen freezes you had? Appreciate your replay.

yes , i hav faced GT at vendor 9.5 version ,

thats why i re-flash 9.3 ....its about 2 months before. Now GT is not gone fully on latest vendor.few devices already faced that problm...probably beacause the hardware and vendor-firmware r not correctly calibrated[also the vendor security patch is out of date -june 2018:(]

i tested syberia,Lineage,havoc with shadow n disruptVIP kernel on latest vendor.everything works fine....no GT issue.

[Xiaomi Poco F1 Questions & Answers] henriluiz:
Replaced the screen, it's the same brand (ebbg) and touch (fts), lot 02.2019. After 12 hours I have no ghost touches anymore, thx God!

Now I can use custom kernels (using Rev os kernel on latest miui beta right now) without freeze and ghost touches.

I haven't noticed any difference (color and brightness) between the original screen and the new one.

Edit: the only difference (and I like it!) is the notification led, brighter than the original one.

I flashed the ak2 kernel and while it did boot up for the miui global I'm using, it screwed the video and audio playback for my poco. When choosing ringtones it would just say Error and videos won't play.

Why are u flashing this kernel on miui global?? Literally no point since its the kernel your already using and can only screw something up, like you did.
[Xiaomi Poco F1 Questions & Answers] hakkai999:
Because I was still using Franco and were still experiencing screen freezing.

Hi. I am just a lurker in xda. But i wanted to share my experience with touch problems (freeze and ghost). I had that kind of issues 3 months after purchase and basically i had to choose between ghost touch or freezes with custom kernels, i chose ghost touches ( with ak2 stock kernel) because it's the one i can live with. 2 days ago, i did a dirty flash/update on crdroid with optimus drunk kernel after flshing the latest vendor. It's been like 40h using my poco with fts_ts panel and no freeze no ghost and maybe it's a placebo but i felt latency touch is way better. Maybe this can help someone these damn screen issues.

I never had ghost and freeze issues on my Pocophone.

What bothers me is that I still dont know what problem I have in the edges of my touch (over sensitivity or input lag)

I already used the Multi touch app and everything appears ok, but when playing games like brawl stars I feel like there's something wrong compared to my old galaxy s8, especially when I have to aim, I feel that its extremely inaccurate.

I have a NVT-ts touch painel. What rom do you guys recommend?

my touch die after reboot from recovery.

I dirty flash my rom to Dev global 9.6.20 from global 10.3.5.0 with orange recovery (wipe cache), after finish I reboot to system. Anything normal, then I reboot, still normal. Then I boot to recovery again will install custom kernel, but my touch not work. Have waiting in recovery but still no respond. Back to system no work to my touch. In this case I havent install custom kernel.

so I clean flash 9.6.2.0 wipe everyting, still not work. Then flash 9.6.20 with mi flash still not work.

what should I do? its broken touch or my machine?

FLash global Fastboot rom then dev fastboot rom, touch works again. if flash via recovery didn't work for me

So if ur on miui and you flash a custom kernel and complain, after reading this thread, then that doesnt make senseeeee
[Xiaomi Poco F1 Questions & Answers] RubenPCA:
Just commented that the kernel r2 does not give problems with this type of screen.

And I'm not complaining because I tried this kernel for 2 days, that in others in a matter of 15 minutes it gave me a frozen screen.

[Xiaomi Poco F1 Questions & Answers] Nil253259:
So spent some time reading all Kernel threads. Everyone is on 9.1.24 it seems as later changes by Xaiomi might not be public yet. 9.1.24 is proved to be the best for both fts and nvt panel.

Surprisingly ny panel is nvt, but symptoms are exactly similar to fts lol. I'm back on miui latest beta. Spent a complete day. And not a single touch issue, as expected.

Unfortunately i see micro stutters here and there with Stock Kernel. Might be placebo, but I am missing custom kernels. Hope I'll be able to use PE with Derp real soon :cyclops:

[Xiaomi Poco F1 Questions & Answers] Vinnom:
hey [MENTION=9610506]Mooatreides[/MENTION] thanks for this thread.

I was getting really frustrated with poco because of this issue. Last night I've found your thread and read it until I found the post where you link to the workaround. As I wanted to move to a caf rom (from los to reloaded-caf), I downloaded last miui dev image (20190620) and flashed it all. I wanted to go pristine.

Then I wiped system and data, flashed reloaded-caf and gapps and tested for an hour so I could be sure that the screen freeze was still there. It was. So I used AIK and switched reloaded-caf kernel and kernel offset with the miui one. Nice! Screen freeze is gone, but ghost touch was there. Then I applied this workaround and sometimes it still occurs but it surely is better than with no workaround. Much better.

So thanks again and I hope this build.prop lines help other ppl too.

PS: if anyone try to apply the lines to the build.prop, don't forget to reboot in order to it works and take care because for some reason some lines are grouped into one in the post I linked.
[Xiaomi Poco F1 Questions & Answers] Adriano-A3:
Placebo. I tried build.prop solution but 0 success.

Guys, what I think causes a lot of confusion on the touch issue is that some kernels come with touch drivers that will overwrite previous one from vendor firmware..

Hey guys, I'm Head of POCO and POCOPHONE. A Twitter user recently pointed me to this thread regarding Screen Freezes. (I'm available at [MENTION=4965939]atytse[/MENTION])

While we can't support 3rd party roms or kernels, I'd be happy to look at any patterns that you can help summarise on how to best reproduce these issues.

(Which build were you on? What touch panel do you have? When does screen freeze occur? Any build performs better than another? )

If someone can help summarise the key issues, especially those that are reproducible, universal and resemble a pattern, that would help a lot.
[Xiaomi Poco F1 Questions & Answers] baiMangau:
I experienced random screen freezes on all stable stock miui roms and all custom roms, lineage, cr, many other.

Fts panel.

Freezing also occurs in twrp.

Screen freezing transforms to random ghost touches around the notch area when using custom roms flashed with stock kernels.

Can't find any pattern. Can't say any combination is better than the next.

While I couldn't find any workaround for screen freezing, I find one for ghost touches - hide the notch so no ghost touches occur there.

[Xiaomi Poco F1 Questions & Answers] silentmann:
I experienced random screen freezes on all stable stock miui roms. It's just random ghost touches and screen freezes, exactly same as other users have, no special cases or patterns needed for that, only ebbg fts panel and bad touch drivers i guess. There was kernels in this thread that can fix that problem, maybe you can copypaste that code in stable rom and that will help to solve this problem.
