[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] neinfricatu:
As I have noticed by talking to several users on telegram group for Poco, there are some batches of touch panels which were ****ed from the beginning, yours and mine included.

At first, I thought that the touch panels are the same and the users don't type fast enough to observe the lag, but I am convinced now this is not the case. Some users have poor touch panels, some don't.

For the users who have the poor touch panel, this 27 update is the same as in the beginning, bringing back the delay. For everyone else, is the best update, as the fixes brought for the poor touch panels, made them all oversensitive, and reverting those fixes resulted in a better and original touch experience.

I don't know how will xiaomi finally solve this, my guess is they wont, as this device is already 4 months old and the interest in it is starting to fade.

I am now hoping that at least do not revert the fixes in the stable version, as I can live with the oversensitivity instead of delay which makes the fast typing a real pain. But, who knows, maybe I should try to learn to build a kernel in order to always have the new updates and the touch firmware which is best suitable for my device.

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] milouk:
Hello and happy new year.

Lets take things one at a time.

Wifi hotspot cant work :

Logs? What am i supposed to do with "Wifi and hotspot can't work" . How can i reproduce it? My hotspot is better than fine. Im not a magician here.

Battery Life no good :

I feel like i need to apologize for this while i dont. How do u know its not your rom? What have you done to identify the culprit? Maybe show me some bbs stats or give me something to hold on? Again , i promise you im not a wizard.

Touch sometimes freeze:

As much as i would like to solve your issue. Its Xiaomi's fault. My "job" is to merge the latest software / firmware provided from the vendors. And that is exactly what ive done. Wait for the next version :)

Cheers

You see? This is what i have to deal with every day!

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] k@iserex:
I have lamented about touch panels in Poco in couple of occasions and left with same conclusion as yours. The truth is that whatever touch panel you/we have its just sub par, I think that's a fact and Xiaomi is cutting corners with those commits on touch response / sensibility / lag / drag whatever inside firmware or vendor packages and while they're more then welcome trying to resolve issues it's just a plain truth that they cut corners to bring the price even further down to be a killer seller they wanted to be out of Poco. Will they ever fix it, I think not. My wifey has mi 8 lite and touch panel is better, not light years better but better to feel the difference and that's enough for me, not to compare it to higher end touch panels which just let me glide my fingers across it with superb and impeccable response. So in that light we can't be to much on the grind side as for the money Poco is really good, would I buy it again, apsolutly Yes, if for no other reason but cos of great community and support, that alone is golden and worth the money.

From where can i get stock boot.img
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] MasterFURQAN:
You can find it inside the flashable ROM.zip.

Or you can also restore a TWRP boot partition backup of the "stock" ROM or a kernel backup from a 3rd party app like ek Kernel manager.

Or just dirty flash the same version of the stock ROM.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Pinage:
Suppose in using NOS with Franco, can I dirty flash the same rom then flash sphinx kernel to start trying sphinx kernel?

Because some people have bad touch panels and some people have decent panels and some people have good panels. For you it's likely you've a good panel if you've no issues from day one.

[MENTION=5533673]milouk[/MENTION] can you please make 2.3 version with previous touch firmware as you know there are some of us experience touch lag with this current touch driver
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] thanhnvt194:
Các

I
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] MasterFURQAN:
All this touch lag thingy on some phones implies that there are some batch of phones with faulty or below par touch panels. When Xiaomi tries to fix it by changing the power parameters (high/ low current/ voltage) , it kinda "fixes" them while making the others over/ under sensitive (thus the lag etc )

This is just a guess that fits this entire scenario. [MENTION=5533673]milouk[/MENTION] can't do much on this case as he can't compile the firmware for the touch panel himself. He is doing his best as all he can do is update Sphinx with the latest available touch firmware to keep the kernel up to date with the latest available firmware among other things.

My recommendation to everyone is to use the kernel version that doesn't cause any touch issues on your device until Xiaomi can figure a permanent solution to this (which is highly unlikely). Or use stock kernel as a last resort if that fixes the problem.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] melodystyle2003:
This statement is so wrong btw.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] JJ111:
Hey friends,

for those of you, who didn't know yet, official TWRP is out: https://twrp.me/xiaomi/xiaomipocophonef1.html

I installed it together with Sphinx 2.3 and LineageOS and so far everything works fine :)

[MENTION=5533673]milouk[/MENTION]: you received your Poco? How's unlocking doing?

All the best,

JJ

---edit---

I haven't faced any issues, but I was told it obviously is not (yet) as stable as the unofficial version. Sorry, didn't know that before.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] k@iserex:
In which way exactly?

I have touch issues on sphinx 2.3 and on top of that black screen of death occasionally on CAF Reloaded ROM, so I reverted back to 2.2 version and touch is better for sure, for me that is. As for BSD will see...
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] thomas140:
Well, in twrp official forum there, many said that unofficial is better. There are many bugs to fix.

Apsolutly possible, but didn't have that on 2.2 version and one thing changed, kernel version, but will keep an open eye. Whatever it is, Sphinx is the best, I can take care for my self ??

Cam anyone please share this kernel with https://github.com/TheScarastic/and...mmit/c40b825dcca9270f92dba2fa969131dfd33e6ec4

This commit ?

As latest touch firmware is worst for me and many more users.

This was best touch firmware around for us.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] k@iserex:
There's no final solution for all due to sheer number of users and who knows how much different suppliers of touch screen hardware installed on Poco. So use whatever works best for you, for instance I feel sphinx v2.2 is best for me in terms of touch fluidity with other things like ROM I'm using and the likes ??
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] SilentEYE:
Is there any way to use latest kernel and flash an older touch firmware?

Or maybe any kernel kitchen?

I feel like being locked out from all new kernel updates out there, if Xiaomi is unable to make a new touch firmware which will work again with my device.

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] shouk_1987:
Touch firmware is binded within the kernel

I am in the same boat as well as my touch is way better with .12.24 f/w than .12.27
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] melodystyle2003:
Since the problem is known, having same kernel revision with different touchscreen fw is possible, but it is up to the developer's mind if he chooses to do it and listen to the community asking for it or not. That way, people like you can benefit by their valuable upstreams/updates without compromising at some point the functionality of their device.

As I have written above (btw, i felt like I was being a bit tactless before when I quoted you, i didn't mean to express any rudeness if so).

I have pm'ed you.

I've been using all kernels available out there these past few weeks, Sphinx v2.2 is the best kernel in terms of snappiness and ui smoothness for my phone. v2.3 otoh is a regression, hopefully the upcoming release will be better than v2.2. :good:

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] SilentEYE:
Potential BUG found.:

Can someone check this :

Lower the max cpu clock for little and big clusters. Set them to get applied at boot.

Reboot your device.

Look on your kernel apps cpu usage graphs. The lowest kernel frequencies are now stuck in higher ranges than normal.

That means your cpu will not scale down anymore.

So applying any cpu clocks on boot, is causing all cores to get stuck in higher cpu states.

Tested on phoenix 2.3 with nitrogen os with Franco kernel manager and a second time with kernel auditor.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] milouk:
Hey JJ,

Yes i have received and unlocked it. 2.3 was tested on my very own Poco :D. These days im really under pressure since i got a million deadlines and also my exams at the same time.

Cheers

Reboot. And let it settle for 2-3 minutes without touching it after reboot.

I think this is a placebo. 2.3 should provide a much smoother experience without a difference in battery drain. Other factors affect battery too like signal, rom , apps, usage etc.

Wrong thread mate. Here is Sphinx for Poco go to the Mi 8 thread ;)

You are very welcome ;)

As i said above many factors affect battery. Kernel im reality can save you very little battery and they definetely dont drain it, unless used unwisely. If you keep my settings you shouldnt experience any drain.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] milouk:
I really dont think thats a kernel issue. Also freqs arent meant to be tampered with id suggest let the phone do its work. Its smart enough believe me. Ill have a look though just in case although i havent experienced your issue. :)

Cheers mate :D
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] MasterFURQAN:
I have this "issue" as well. Lower frequencies aren't being used. Here's a screenshot on Kernel adiutor for better debugging. Using 2.3. I think this kernel version is working much better than other versions for me except for maybe a little more battery drain. I'll come back with the proper stats. Thanks again for this awesome kernel. ?

[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Stampyron:
Check your min CPU freq. If they're stuck then reboot and if that doesn't work then flash the kernel again.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] SilentEYE:
Did the things you said and the problem appears again. I was always able to reproduce it.

It just appears if you set any frequency on boot.

Tried Franco kernel just to cross check and it didn't happen.

I know this problem from older devices, getting in "conflict" with kernel manager apps.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] MasterFURQAN:

Hey!

I want to share my experience with the kernel so far:

2.1: touch is perfect, batter drain is very good, I got almost 0 wakelocks, which I'm very happy with ? only the frequenies jump around and they are on the higher ones all the time (kinda like stuck, but not)

2.2: weird epoll wakelocks appeared and they wake up the phone with enormously high counts

2.3: touch is very bad, especially when typing, epoll wakelocks are still there and waking up the phone, so the battery drain is really high

Can someone tell me what are these epoll wakelocks?

Battery life is definitely worse on 2.3 than 2.2. I trried clean flash and everything. Battery drain is especially high on standby. I entered work with full battery and after 8 hours it was under 70% and I didn't even touch my phone.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] mr_oxalis:
same with me..2.1 touch is perfect..already try 2.3 for half a day,now restore back to 2.1 due to touch problem
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] nabildanial:
In this case, it wasn't a placebo. 2.3 really was causing some lags especially during gaming, but it turns out it has some incompatibilities with the thermal-engine disabler that I was using (Chrysalis Thermals magisk module). It doesn't cause lags without the disabler, but without the disabler my phone gets thermal throttled very quickly. The workaround for that is I have to use ondemand scheduler instead of schedutil, everything works very smoothly and snappy right now (didn't notice any battery draining so far).
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] milouk:
Thanks my friend :),

Once im done with all my exams and assignments ill be baack 100%. Both at the support and the releases

Im merging all the latest firmware from Xiaomi. Unfortunately there is not much i can do besides that :(

Ill post a relevant post in the following days. There is a great misconception about kernels. Users who flash kernel to improve battery have it all wrong in their mind. You should want to flash kernels to patch the security issues and improve the performance. There are only a few things that can improve battery and you shouldnt see that much change. Also something very important no one pays attention to is that kernels DO NOT DRAIN battery. 1,2,3 hours drain reported by some users is just no right. That said , wakelocks do NOT drain battery. They just keep the phone from going to sleep causing OTHER things like apps etc drain the battery. Im very into spreading the knowledge instead of just distributing my work so ill post a relevant educational mostly post in the upcoming days ! Cheers man :)
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] milouk:
You are very welcome man :)

Check my post above ;)

Im sorry not much i can do. I always merge the laatest firmware by Xiaomi

Really sorry about that. As you can understand i cant predict side effects of every rom, app, config, hack.

I would suggest keeping it as clean as possible just for your own sake so you can debug easier what causing issues. :)
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] TioCareca:
[MENTION=5533673]milouk[/MENTION] you will keep your kernel based on lineage or you may think base it in caf?

Don't know if any advantage in that but i read that it may be better...
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] Stampyron:
Well the thing is you're not supposed to change the freq unless you want to underclock the device
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] SilentEYE:
As soon as the kernel allows to UC it should usually work as supposed.

Fk kernel and other kernel apps battery life profiles base on this process.

I just wanted to show that applying UC on boot is acting faulty than applying later.

This is clearly not the way the dev wanted his kernel to work.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] nabildanial:
No, you didn't do anything wrong, like I said 2.2 was good out of the box, its just 2.3 need ondemand to work properly. I don't use any scripts/tweaks at all aside from this kernel and the thermal-engine disabler, on Syberia ROM.
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] milouk:
Actually both. I base it on los -which partially is caf- and i always merge ALL caf tags for sdm845. (The latest is 06600 and its already merged since 2.3)
[Xiaomi Poco F1 ROMs, Kernels, Recoveries, & Other ] milouk:
There may be a collision because my pre configured settings are trying to get applied on boot. Hence the kernel manager's settings you want to be applied on boot get overwritten by mine's. I would suggest setting the delay as long as possible.
