I have an old phone with mt6589 CPU which does not support newer Android versions that is later than 4.4, so CF.lumen and KCAL would not work. I did try Color Changer Free and it works fine, but laggy overall and could not be used when playing videos.

Hi

After the pie upgrade I can't find multiwindow settings or combine apps in the recents apps window.

Where are those options?

Thanks!
[Samsung Galaxy Note 9 Questions & Answers] davec38:
Long press on the app icon on the top of the windows in the recent apps section and you can see options for split screen and pop up view.
[Samsung Galaxy Note 9 Questions & Answers] bat0nas:
Thanks!!!!

That is what I was looking for.
[Samsung Galaxy Note 9 Questions & Answers] Mr. Orange 645:
Not sure why everyone says you have to long press. All I have to do is just tap the icon and that menu pops up.

I've been trying to hard reset it and I've tried all the button combinations on it found on the internet.

[Xiaomi Poco F1 Questions & Answers] Mooatreides:
Im still getting screen freezes on my poco with FTS_ts touch display panel. Apparently the problem is solved in latest miui stable and betas. Nomatter which new vendor/firnware i use its still happening, so the fix must be somewhere else.

Can this be fixed by custom rom developpers? Is it something even in the works? Will kernels in custom roms get the new touch firmware from 9.3.14 or 10.2.3?

Its really getting unbearabke having to close and reopen the screen all the time to get regular usage.
[Xiaomi Poco F1 Questions & Answers] riseofsand:
10.2.3 Vendor is very old

9.3.14 Vendor is old for Pie you need a version hier than that
[Xiaomi Poco F1 Questions & Answers] ron_hyatt:
these are the most recent!!
[Xiaomi Poco F1 Questions & Answers] youssefhf:
ive had this issue since getting the phone, it felt amazing when they fixed it

then i flashed lineage and its worse now

which sucks because lineage is much better in pretty much everything imo

i hope they fix the screen asap its unbearable
[Xiaomi Poco F1 Questions & Answers] ron_hyatt:
so was it really fixed on 10.2.3 global stable?
[Xiaomi Poco F1 Questions & Answers] youssefhf:
i flashed the 10.2.3 stable a few days ago and haven't had a single screen freeze issue.
[Xiaomi Poco F1 Questions & Answers] Mooatreides:
We need an indoustrious developper to bring the kernel fix to custom roms,

does miui kernel in lineage os fix the touch?
[Xiaomi Poco F1 Questions & Answers] Mooatreides:
Hey im actually running latest Pixel Experience with vendor/firmware 9.3.21 and the kernel from miui 9.3.21(extracyed boot.img from full rom) and everything is going good , no freezes, pubg is good and.good SOT.

I tried it with crdroid the rom i like the most and it dint work, so not sure it will work with LOS, but PE it does.
[Xiaomi Poco F1 Questions & Answers] Mooatreides:
GUYS we got a workaround!!!! follow here in this part of the LOS thread [MENTION=5564863]youssefhf[/MENTION] there is a kernel for LOS

[Xiaomi Poco F1 Questions & Answers] Sushi3110:
Mine freezes, too.

After what I read here, is it the kernel? I'm using Franco Kernel since forever and used it with all the ROMs I tested on the Poco F1 (AOSPExtended, AOSiP, HAVOC) and this problem is escalating. Just a few minutes ago i wasn't able to put my pin in after a reboot. Turning screen on and off didn't work as it does sometimes. I was able to put the pin in one time, but then I couldn't confirm it. :D I had to reboot again to put it in and confirm. I am always using the latest vendor/firmware but it didn't get better. It got even worse in time.

Is it the Franco Kernel? Or AOSP ROMs? Would be great if I could keep using the kernel, but if there's no other way...
[Xiaomi Poco F1 Questions & Answers] Mooatreides:
Read the post in los thread i quoted

This guy put a kernel for crdroid and one for LOS, im on crdroid and it works.

I ised PE with miui kernel and ot worked also. What rom are you on?

Try any of the three i mentikned with the kernel he posted. Here https://drive.google.com/drive/u/0/mobile/folders/1zGc3v1ahsN2dpkPppNAJJMDHKl8jnQmj?usp=sharing
[Xiaomi Poco F1 Questions & Answers] Nil253259:
Having exact same problem. Tried almost all vendor firware without any success. I'm on latest PE, so gonna flash stock MIUI 9.3.21. Do I need to flash twrp after flashing stock boot?
[Xiaomi Poco F1 Questions & Answers] Sushi3110:
Hey! I'm using AOSiP with Franco Kernel at the moment. I'd like to keep using it because I prefer AOSP ROMs over LOS / LOS based ROMs. So from what I have read I guess it really is a a kernel Issue if it works with the kernels provided in the post you mentioned.

Maybe it is possible to make a kernel for AOSiP ROM or maybe Franco can make a modified version of his kernel for people having this problems.
[Xiaomi Poco F1 Questions & Answers] misleaded:
What ROM+Kernel combination that you are using right now that fixed screen freezes for you?

I'm on MIUI 9.3.24 on latest Franco kernel tho.

I'm facing series of screen freezes
[Xiaomi Poco F1 Questions & Answers] Nil253259:
I'm on latest PE and as suggested flashed stock MIUI 9.3.21 Kernel with 9.3.21 vendor. No screen freeze in last 12 hours
[Xiaomi Poco F1 Questions & Answers] Mooatreides:
Im on crdroid with the kernel this generous guy posted for us. Im going to try and make my own fix next time.

Its miui beta kernel in crdroid boot.img

On PE u can just take the boot.img 9.3.14+ of miui and it works to fix screen freeze
[Xiaomi Poco F1 Questions & Answers] Mooatreides:
Yeah mann!! Glad to hear
[Xiaomi Poco F1 Questions & Answers] Mooatreides:
Uae the stock kernel wjy franco if your on miui sot is great, and u wont have freezes, franco doesnt have the fix
[Xiaomi Poco F1 Questions & Answers] Marc'Z:
No issues so far
[Xiaomi Poco F1 Questions & Answers] Mooatreides:
Thats great man luckyyy, i hate that ****, happened to me on crdroid and Havok. I havent gone back to PE reasoning being if i need to put miui kernel anyway why not take a rom with more features.
[Xiaomi Poco F1 Questions & Answers] Baffsuki:
This is getting ridiculous. Why hasn't Xiaomi published the fix when this issue has been going around for months. I'm slowly getting fed up with trash Xiaomeme as they try to fix problems and then bear new ones for them to fix. Ugh.

I just want to use Pixel Experience with Arter's kernel, what's so bad about that? iM gEttInG MoRe FruStRaTeD everyday with this heccing phone

F*** Xiaomi. F*** this cursed phone, I'm never getting another phone from this brand again
[Xiaomi Poco F1 Questions & Answers] mikedavo:
Sorry, I meant "fingerprint camera shutter" I disabled it in accessibility in settings as part of tracking down my screen stutter issue which was bugging the hell out of me.

The screen froze when I disabled it, so after restarting the phone I immediately felt a difference.

I went back to this setting and enabled the setting and the stuttering started happening so I disabled the setting and pow! Screen freeze, I restarted phone, smooth again.

What I'm saying is one app caused this kind of issue to the point of needing a hard reset.

The stutter seemed random at first but when I look real close I noticed it's always there but curtain apps, like for me Facebook, YouTube, sites with a lot of graphics going on, made it really pronounced.

Take from that what you want. :)

[Xiaomi Poco F1 Questions & Answers] youssefhf:
so stock kernel only works with pe caf?
[Xiaomi Poco F1 Questions & Answers] Mooatreides:
No i only tested on aosp but doesnt work anymore, you need to use the zips ipdev made with any kernel
[Xiaomi Poco F1 Questions & Answers] youssefhf:
so if i wanna use it with los ill need the specific los one?
[Xiaomi Poco F1 Questions & Answers] Mooatreides:
No the zips work on all roms but you may get ghost touch that brings down notification shade. In ipdevs drive youll see files that end with ak2.zip, use that.

Pair with same vendor i guess
[Xiaomi Poco F1 Questions & Answers] youssefhf:
will i need to reflash kernel everytime i update los or ?
[Xiaomi Poco F1 Questions & Answers] Mooatreides:
Yes ofcourse, when dirty flash a rom ot puts the roms kernel also
[Xiaomi Poco F1 Questions & Answers] billabongstaff:
The Solution summed up

Ok, guys.

As per OP's request, I'm reposting this.

Thank you @Mooatreides

The short how-to:

1 - No point on trying those fixes where you turn this and that off, those are just placebos;

2 - Go here:

https://drive.google.com/drive/folders/1zGc3v1ahsN2dpkPppNAJJMDHKl8jnQmj

3 - Download these two files:

POCOF1Global_9.5.13-ven-firm.zip

&

kernel-beryllium_global_9.5.13-ak2.zip

4 - Flash those zip files using TWRP;

5 - Never again have any screen freeze. You may experience an occasional accidental notification pulldown (ghost touch), but it's very rare and you can live with that.

Explanation:

Quite simply, the magic behind this is that you're flashing a well known original Xiaomi Kernel (from Global 9.3.21) that has no (few) touch issues, instead of running Derp or whatever.

Not a biggie for me, but to each his own.

I, for one, would much rather have a functioning display with an original Kernel rather than rage breaking my screen after 1892132378 times of it freezing and having a custom Kernel just for the sake of it.

If it weren't for @ipdev, you'd have to decompile and recompile Kernels into boot.img and what not. So special thanks to him for making this SO MUCH EASIER.

NOTE:

Obviously I assume you:

1 - Have unlocked your bootloader;

2 - Installed TWRP (or any Custom Recovery);

3 - Have a Custom ROM (or not);

4 - Are running and want to run Android 9.0 Pie;

5 - Know what you're doing.

Let us know how this worked out for you guys (I'm pretty sure it will go smoothly, but still, feel free to reply here so others can see results).

Cheers, guys.

I did the same thing and the touch lag is GONE! No ghost touch and notif pulldown as of the moment.

I think it's definitely a kernel compatability problem.

I'm on ipdev 9.5.13 vendor + PE CAF 05082019 + ipdev 9.15.13 Kernel.

And now it seems to me that vendor+firmware 9.5.9 or later is all it takes to stop the freezing.

Got the ghost notification pull down though but hiding the notch fixes that. :D

Gonna try updating to 9.5.13 tonight.

I'm on 9.5.13 and 20190518 PE CAF edition. Still having an issue when the screen is flat down with the table, it does not register touch on the upper side of the screen. But for normal usage is very good now. No ghost touch or unresponsive behavior.
[Xiaomi Poco F1 Questions & Answers] henriluiz:
After use the patched kernel + vendor + firm of ip dev that reduce drastically the ghost touchs, I was a little disappointed because I can't play games like clash royale because of the ghost touchs.

I've seen many posts talking about the "touch stability" on global stable 10.2.3 and decided to try it and the ghost touchs are gone (more than 4 hours of usage - playing clash royale and other games- and no ghost touches!). The sad part is that 10.2.3 is a old rom without some new miui features. :(

I see many miui kernels on ip dev drive, but is missing the 10.2.3 zip kernel. Can you guys try to catch the kernel / touch drivers from 10.2.3 global stable thus we can try it on the latest betas? Please... :fingers-crossed:

Thanks in advance.

Thanks for your hard work,
[Xiaomi Poco F1 Questions & Answers] hyborian:
I feel your pain, hope the custom devs can figure it out. I don't have an FTS panel, but it might suddenly happen to us too.

This reminds me of my Xiaomi Note 4X, I bought two and they turned out to be MTK variants, argh. Faster than snapdragon, but also really faster battery drain. Xiaomi should stop with these different variants like two different panel vendors.
[Xiaomi Poco F1 Questions & Answers] Mooatreides:
There is a kernel zio for 10.2.3 check in the X-Files folder.

10.2.3 was before the fts fix though? I dint try the stable kernels ill try 10.3.4 n see if theres ghosts

Edit: got a ghost in first 5 mins with vendor 9.5.16
[Xiaomi Poco F1 Questions & Answers] billabongstaff:
There is also one for 10.3.40.

I am not sure anymore which is the latest or how the numbering works.

I thought the 10.x referred to the MIUI version, not the Vendor/Firmware or Kernel.

Can anyone shed some light on the subject, please?

Maybe [MENTION=7280276]ipdev[/MENTION]

?

I am really not sure which is the latest, but if anyone will enilighten me, I'll flash it and try it.

The Firmare+Vendor itself and...

The Kernel.

Either with the 10.3.40 version or the 9.3.21 hybrid.

If anyone could extract and provide the two version, I'd give it a test run.

I don't want to mess up using Android Kitchen.

I don't want to harass [MENTION=7280276]ipdev[/MENTION] ,but I can ask.

Can you help us out?

Best regards, man.

EDIT:

Been using 9.5.17 for 20 minutes now, ZERO ghosts touches or pulldowns.

And on a side note I'm using a build.prop tweak to improve touch accuracy.

I found it online after much fiddling around.

I can share if you guys want me to.

Cheers.

[Xiaomi Poco F1 Questions & Answers] henriluiz:
I ser that, a zip contains vendor + firmware. I didn't see the boot.img inside.. I'll try this.

Zero ghost touches here in 10.2.3.

The miui version follow a alphanumeric order, I don't know how they pick the number after the 10.

Can you please try the app multi touch? Put 2 fingers on the screen and see if The ghost touches appear on the left top side as a third touch.

I've tested the kernels on clash Royale, by pressing the touch and th bug occurs.
[Xiaomi Poco F1 Questions & Answers] Mooatreides:
In on 9.5.16 still have ghost touchs, 9.5.17 jusy came out no?

10.x are stable builds. 9.x are beta

The kernel zips literally say kernel in the filename and have ak.zip at the end.

Edit: its been about 45mins im using vendor firmware 9.5.17 and ipdevs universal 9.5.17 kernel and havent had a ghost yet! it may be it! im hopefull!

thanks alot to [MENTION=7280276]ipdev[/MENTION] for everything!!!

if its all good im going to make a bootimg for havok and crdroid with 9.5.17miuizimage in it and upload to my drive.
[Xiaomi Poco F1 Questions & Answers] Mooatreides:

Vendor Firmware 9.5.17

latest Havoc OS

No touch freezes nor ghost touches here so far, looking clean and neat.
[Xiaomi Poco F1 Questions & Answers] henriluiz:
Good news! Hope it's works well finally! I'll test it asap.

But I already bought a new screen on AliExpress (ordered under extreme anger and frustration with the current touch problems lol)

Can you please share the build.prop commands that you are using?
[Xiaomi Poco F1 Questions & Answers] billabongstaff:
Thank you for this explanation.

Finally, some sense in the numbering.

Everyone, please note:

9.5.17 Vendor+Firmware & 9.5.17 Hybrid Kernel are working 100%.

Going on a lot of hours of use and gameolay (for testing) and no issues whatsoever.

The build.prop commands I'm using are as follows:

********************

touch.presure.scale=0.001

persist.service.lgospd.enable=0

persist.service.pcsync.enable=0

ro.ril.enable.a52=1

ro.ril.enable.a53=0

persist.sys.ui.hw=1

view.scroll_friction=10

debug.composition.type=gpu

debug.performance.tuning=1

#advanced touch settings

touch.deviceType=touchScreen touch.orientationAware=1 touch.size.calibration=diameter touch.size.scale=1

touch.size.bias=0

touch.size.isSummed=0

touch.pressure.calibration=physical touch.pressure.scale=0.001 touch.orientation.calibration=none touch.distance.calibration=none

touch.distance.scale=0

touch.coverage.calibration=box

touch.gestureMode=spots

MultitouchSettleInterval=1ms

MultitouchMinDistance=1px

TapInterval=1ms

TapSlop=1px

**********************

To use them, just add a new line at the end of your build.prop and paste all of the above EXCEPT the ******************** at the beggining and the end.

Finally a mix that works flawlessly for me.

I hope I did my fair share to help you guys and I thank everyone who helped me.

If anyone has any questions, let me know.

[Xiaomi Poco F1 Questions & Answers] Baffsuki:
When you're in the recent apps menu, you hold an app (not the icon but the snapshot of the app) and then once the three bubble-like icons appear, you click the middle (the one that represents split screen) and then choose another app.

The same can be done by just clicking the "split screen" icon at the top left when you're in the recent apps menu as well.

Once you receive your screen can you report back here see if it changes anything ?

Honestly I hope to receive a different (and good!) touch panel (not fts or nvt).

That's my second poco, the first one came with nvt (horrible swipe gestures ever), bought a new one with fts and get these ghost touches.. Very unlucky.

Unfortunately there is no much information regarding the panel brand, but is cheap and I've seen many positive feedbacks from customers on the product details and decided to buy one. link below;
