hey [MENTION=4965939]atytse[/MENTION]

for me is the same as greatly summarized here.

For now, I'm on Reloaded-caf Rom using stock miui kernel extracted from 20190620 dev boot.img

I had ghost touches then, but after applied some build.prop lines, it is somewhat fixed (ghost touches is very rare for me now). I didn't try to disable notch as suggested by [MENTION=9921606]baiMangau[/MENTION] but will try (gonna comment build.prop lines out and try the hide notch approach)

Hello and thank you for making an effort for trying to help us.

I use Xiaomi.eu 10.3.5 stable and i notice often my screen freezes when im not touching the screen for a while. My display is fts
[Xiaomi Poco F1 Questions & Answers] Mooatreides:
Hey Alvin thanks for your post. I have two pocophones, i was usong one with fts panel for a long time because i dint want my girlfriend to deal with freezes and stuff, finally i put xiaomi.eu on the fts phone and gave it to her so she would have more room(fts is 128gb) and i took hers that has 64gb and nvt.

So far she hasnt had one freeze but if you read through this thread you will see exactly tge problem, across all custom roms and even miui until March i believe.

The developper of Optimus Drunk kernel [MENTION=5293805]GtrCraft[/MENTION] is trying to experiment with the fts panel drivers from the mi mix 3 5g amd there is sone promis for users.

The big problem is when kernel source was made public there were only nvt drivers, then xiaomi started including fts touch panela but never gave the drivers.

My fts poco is from 8/2018 but more recent batches dont seem to have the freeze problem.

Use beta my gf has 9.6.20, no freezes at all, the stable has older drivers.

Pocophone 128 Mb NVT-TS

I get some screen freezes in TWRP, in Chrome and in Configs. That doesn't happen all the time. Sometimes I'm reading some infos and it freezes. Sometimes I have to update a module using TWRP and I can't simply get the Install to work.

I'm using ROS MIUI 9.6.23. I've tried some diff builds and also diff ROM's .... It can happen at any time.

My littlephone is dated 12/2018 and has freeze problems.

---------- Post added at 04:57 PM ---------- Previous post was at 04:54 PM ----------

This problem occurs randomly in all FTS touch panels, my littlephone is 6GB / 128GB and has said display, in MIUI Stable the tactile sensitivity is low compared to the beta, the side of the notch is where more touches ghosts presents.
[Xiaomi Poco F1 Questions & Answers] Andro Syr:
Hey Alvin, I had my poco since February, i had ghost touches since then but it was once a day, but recently its gone worse, last weeks my phone is not useable anymore, i tried everything, locked bootloader with every single rom since January, and every kernel here on XDA, some time ghost will stop after flashing new setup but it will be back after couple of hours,

Sadly there is no pattern, its random Chaos,

It is sad that all the threads in miui community and old Xiaomi Forum didn't get your attention before

Anyway I have sent my first and last Xiaomi phone back today, hopping to get my money back or maybe an expensive decoration in my drawer.

Edit: i had damn Fts panel

Various touch issues on an NVt panel for POCO F1 which i have been facing

I have an NVt panel and the touch response on it isnt good at all. Well typing on it is way too annoying. I just cannot type fast any more bcs of this. 8/10 times im always having typos bcs of the unresponsive touches while typing. I have tried various kernels/ miui beta builds/ roms ets as well as miui kernels but nothing seems to help. 9.5.6 as well as the 9.1.24 touch drivers. None of them seem to fix these touch issues. Also there is a slight bit of ghost touch in the middle of my screen which makes any launcher open and close on its own. Its been months since poco is out and its just sad to see that such issues still persist. I know Xiaomi has given us excellent specs at such an amazing price but giving us such horrible panels is just not right. I have lost all my hope of software fixing these touch issues and using my phone the way it is meant to be.

Thanks for reading it if you did.

[Xiaomi Poco F1 Questions & Answers] henriluiz:
I'd one screen with fts touch with ghost touches and freezes, lot 12.2018. But after replace the screen with a fts panel lot 2.2019, I have no ghost and freeze touches. We can assume that some fts panels from 2018 and 01.2019 have screen touch problems.
[Xiaomi Poco F1 Questions & Answers] thedoctoroftech:
Well I still have an issue where enabling or disabling the notch changes the theme to classic and when I go to change the theme back again to the default (I use Poco) it doesn't change so I have to reset my phone.

This problem started to happen with the firmware released in March/April (10.3.4) I'm now on 10.3.5 and I have none of the screen freezing and no audio issues

I also still have an issue that has been with me since the first time I brought the phone where if I want to go back and edit text (Say I missed a word and want to edit a word in then it will delete some or all the letters in the next word )

The text editing bug is really annoying but not as annoying as sending bugs and reports via the feedback app and not hearing anything back or seeing any bugs I have reported being fixed.

Doesn't leave me with much confidence in buying anymore Xiaomi phones
[Xiaomi Poco F1 Questions & Answers] Vinnom:
Oh man, it seems you were unlucky. But as some here already experienced this issue fixed with workarounds, it seems it isn't hardware related. If it is software related, no one better to fix the issue than the head of this product line :)

just fyi, here is my multi touch test :)

Pretty great device and love the battery life and all the features but ++1 I agree with this NVT panels are suffering with problems too, accuracy for typing on keyboard for example is pretty terrible. When typing its more miss than hit
[Xiaomi Poco F1 Questions & Answers] jineshpatel30:
Same issues here with NVT panel & MIUI latest beta.

Plus Scrolling is also horrible on POCO it never actually get better even after so much testing by POCO team with various software fixes.

Basically, Touch screen's Scrolling doesn't match with finger's fling speed there's always friction in Scrolling and random freezes on screen.

[Xiaomi Poco F1 Questions & Answers] droidjunky90:
Dear Atytse,

I am writing to you this letter and I do hope someone takes a serious action towards this matter, I truly love the Pocophone F1 and its high end specifications with a very low price, however I and many users are facing a serious problem of screen freezes and ghost touches which to be honest makes the device almost unusable, this is a serious obstacle that Xiaomi isn't paying attention to, moreover Pocophone F1 is a device that supports custom development however we are not seeing much in the custom development industry due to the lack of sources we have from Xiaomi, please treat this matter with high priority and urgency to fix it, am a fan of Xiaomi products since day one and so many others, but if this problem persists am afraid many users will go a head and be a customer of other manufacturers, which I and many more wouldn't be pleased to occur, as its worth mentioning again this is solely a problem that pertains to Fts_ts panels and unfortunately the latest vendor/firmware didn't solve the problem just yet, as I do also insist on the fact that Xiaomi supports custom development to Pocophone F1 however this is no where to be noticeable in the open source community.

Yours sincerely,

Moe

Screen Freeze, Ghost Touch, Typing Issues - POCO

I hope I can be of help to you, so you can be of help to us, haha. I'd like to start off by summarizing the issues we are having.

TO BE CLEAR, THE ISSUES EXIST ON BOTH CUSTOM ROMS AND OFFICIAL MIUI. I obviously had MIUI when the phone came, but because of the issues I'm about to describe, I tried to fix it with multiple custom ROMs. None of them work. To simplify your work, I will give you the issues I experienced in MIUI, but please note that these exist across all ROMs.

The Issues: (FTS Touch Panel)

- Occasional "screen freeze" where the screen stops responding altogether and the only solution is to turn the screen off and on again. The frequency of this varies from every 5 seconds to every 10 minutes. The screen does not freeze, though, the screen still changes, for example, when the clock changes. It's more of a touchscreen freeze.

-"Ghost Touch" in the top left, and sometimes top right, corner of the phone. This causes the notification tray to pull down at random times, I'd say the frequency is consistent at about once per minute, but changes while swiping a lot. I've resolved this by hiding the notch. :rolleyes:

-Keyboard Issues. This one causes typing delays, and while typing fast, it gets worse. A good example is if I want to type "ququququ" it will actually look like "quqqququuuqqu". Another related issue that it seems like only I have is the random "q" in almost everything I type. Writing this response took a while because I had to delete "q"s in almost every word I typed.

That is the sum of our issues. You simply will not be able to recreate it on another new pocophone because it seems like these issues only exist on a certain batch of FTS panel POCO's. We have had these issues from the very start of owning these phones.

I truly hope you and your team can resolve our issues. I have been suffering with this for a long time, and I love the POCO, I love the platform, the price, the specs, and the idea of it. But these issues seem like they have been with the phone since I purchased it. Unfortunately, I can't return the phone because I bought it online, on a website with nearly zero customer service. Even if I could return it, it would take 8 months for them to get me a new one because of their surprisingly slow shipping.

Any help at all would be immensely appreciated. Thank you.

-Jesse
[Xiaomi Poco F1 Questions & Answers] iroshan:
Could you make the arrangements to release the source for fts touch panels?

This would greatly help all of us who suffer from touch issues.

Currently only kernel with less issues is the Optimus drunk kernel. It doesn't update the touch firmware so it leaves the miui firmware.

Thanks.

I love the Poco but getting tired of touch problems.
[Xiaomi Poco F1 Questions & Answers] DadiFern:
I experience the issue during every games, when the phone is heated up during the game and yeah my phone heat up with just 10 minute game like pubg or mobole legends, and when it happens the screen freeze for a moment and ghost touches appears. But when the time i log out or exit the game, the touch goes back to normal. I've updated my phone to the latest update which is miui 10.3.4 and currently im in miui 10 9.6.20 global beta hoping the issue will be gone but unfortunately it still persist. My touch panel is fts.

[MENTION=4965939]atytse[/MENTION] i do own poco f1 with fts touch panel.

yes, screen does freeze some times, very rare , but annoying. especially the screen will freeze when power low . I notice it last night, i still have 10 percent of battery, still i open pokemon GO to check my status, and the screen freeze. Apps are running well but i can't do anything except press to power off. And most of the freeze happens when i play pokemon go.

I bought POCOPHONE F1 one month ago.

First 10 days no issue.

Did hard reset two times.

Now my device is almost not usable.

It freezes frequently. When i use it and changes my phone angle it got freeze. I try to use multiple app it got freeze...

In video player, after 5-6 min it gets freeze.

I use it with my left hand mostly, during use if i use my right hand once it got freeze.

Sometimes it freezes 6-7 times within just 1 hour!

Even, as i tried to reply here, it got freeze during google captcha

During freeze volume works

To use it again, i do lock screen and unlock it again.

Huge multi type and gesture issue

I have fts_ts, MIUI 9.6.25

Any luck? It's been fine for me with the notch disabled. Tried enabling the notch again just to see if the problems are still there and indeed, ghost touches began immediately.
[Xiaomi Poco F1 Questions & Answers] raphielscape:
Why y'all don't just push all the changes on my every MIUI bumps to Xiaomi OSS, we always fine with your squashed commits anyway thanks to BSP lol

The only firmware version that works a bit better for me is 24 (Oreo stack) and 34 (Pie stack), it's Novatek, the issue happen on some firmware version, killing my edges, and then it's has touch latency in every other firmware iterations

And it's already a year and half to see you putting attention to this lol
[Xiaomi Poco F1 Questions & Answers] miimaa:
I bought my Pocophone on December. Because I don't like Miui, I rooted it right away and flashed Pixel Experience + Sphinx kernel. At the moment I'm on Franco's. I have never have any screen freezing or ghost touches.

Because I was so happy with this phone, I bought one to my girlfriend.

She has had screen issues from the beginning. First weeks she was on stock Miui and she said the phone is unusable. A week ago I rooted her phone and flashed her the Pixel Experience but the issues are still there.

We both have NVT-ts -panels.

[Xiaomi Poco F1 Questions & Answers] MichaelScott5:
The weird thing is when I bought this phone, I immediately updated to 10.2.2.0, and I never experienced any touchscreen issues, I thought I was lucky, the phone is from December batch. Then a few weeks ago I tried to install Pixel experience since I would much prefer a stock like software, screen freezes and ghost touches were everywhere. Then I started over, installed latest beta vendor and kernel, screen freeze was gone but ghost touches still there. Then I went back to full stock again and everything is normal. Something is definitely in the stock rom or kernel which is not available for developers I think. It's a shame since PE would be perfect.
[Xiaomi Poco F1 Questions & Answers] baiMangau:

I would try it if I hadn't foolishly deleted my LOS backup image. But now I have to start everything from scratch if I want to check it but i'm just so sick of flashing and reflashing.

I'm so tired with all this and I'm just going to stick to disabling the notch on my current setup for now.
[Xiaomi Poco F1 Questions & Answers] Mooatreides:
Bro I got great feedback from someone already, this fix on LOS could be the real deal FTS REDEMPTION.

Everyone who can should try the ne unofficial LOS, soon enough Crdroid, RR, NOS and the other LOS based roms should have it also.

cc [MENTION=7280276]ipdev[/MENTION] maybe you would like to try? I saw your last post was quite exasperated.

I also find it verrrryyyyyy interesting that this LOS with a fix comes out the day after Alvin post hmm, months of nothing and then all in one bang. And I don't even have my fts panel phone anymore ha. My GF loves xiaomi.eu on it n wont care even:eek:

V10.3.5.0 Vendor/Firmware

lineage-16.0-20190625-UNOFFICIAL-beryllium

SimpleGapps + Google Keyboard

Magisk (canary - debug)

Will do a quick restore, backup and clean up a few things, then I am planning on re-flashing lineage-unofficial, setting it up completely and give it a full day test.
