Hello,
The ROM I have installed caused the fingerprint sensor to stop working. The last time this happened(on the same ROM) I have flashed a custom kernel and all went well. As time passed, the development of this device's software went on, CFW became a thing, and a lot of custom kernels disappeared. Only one I have found on XDA is this one, whose github repo has been deleted.
Searching outside XDA forums I've found this page, which seems to offer a few kernels, but I've tried 80% of them and none have fixed my issue. Are there any other custom kernels which I didn't find? Is there anything else except trying a custom kernel I could try?
Thanks in advance,

Hi Guys, I thought I would make a thread here as i can not seem to be able to find a solution. Rooted my device obviously, everything is fine until I installed a "Kernel" (cant remember author) to overclock mainly then encountered several problems. 1: Wi-Fi has become unstable. It seems to either crash my phone or signal disappears after my phone is on standby for a period of time (variable). 2: My Bluetooth just does not work. At all!! I have not done anything more to my device so the solution (hopefully). I forgot to mention that it is STOCK ROM. I do not wish to wipe my phone clean, i want to find a fix. Possibly a more stable kernel. Overclocking does not want to happen either but the "Governor's, I/O Scheduler's and Underclocking" do work. If there is anything more you guys need to know please ask!!
Looking forward to ideas

It not the root that causing the issue, it the kernel that tried. If I remember correctly there's only two kernel for the S4 mini that allows overclcoking, and one of them has stopped developerment since last year. That leaves the F4k kernel.
He has two different kernels: one for the AOSP/CM (custom) ROM another is also a bit outdated for the default Samsung TouchWiz ROM. Are you sure you've download the correct kernel?

Well to my knowledge I had used the correct kernel....... I never used one from here but I did find a website claiming that F4k has a stock over clocking kernel...... Unfortunately for the life of me I can not find this website. I've managed to overclock with success using a apk. I found on here (performance control) brilliant tool!! Is there any chance you able to post a link to this stock kernel you talk about so I can test myself and report back? Everything else is working without a problem apart from Wi-Fi and bluetooth.

So I've come to a conclusion after many weeks of testing and searching........ Unfortunately the overclock kernel for "TouchWiz" roms is unstable........ looking through forums I can see that F4k has only realised a "test" version....... on the other hand I have found a kernel from Vikinger (if spelt correctly) that's has fixed my issue and is working great... shame it isn't overclocked nor under and has no additional governors..... any one with ideas please feel free to share..... many thanks.

Did anyone of you guys have the LCD-wakeup problem with horizontal grey lines? (it fixes itself after couple of attempts to unlock the phone and mostly occurs after probably deepsleep OR if there is cold (?) outside ;]
IT DOES NOT occur on CM10 by dr.harald or ANY stock Samsung firmware (also Gingerbread is NOT affected).
But occurs on any 10.1, 10.2 and 11 by anyone (so far ;/
My Ace2 is using pri_lcd_ws2401 driver
Never happened to me and I used many roms, including CM11 by team canjica now.
However I don't know how to check my driver
You can check this under
/sys/devices (you can browse there using Total Commander or any other file manager capable of browsing the whole filesystem on the rooted phone)
Here you should have either :
PRI_LCD_WS2401.0 (like I have)
or
PRI_LCD_S6D27A1.0
Currently I have installed (for testing as usual before restoring the CM10 from backup) CM11 from Team Canjica with the following kernel by PolishVodka :
http://www.mediafire.com/download/yie7ps4irxz5zbl/KERNEL_KK.zip
(I've found it on the following thread : http://forum.android.com.pl/f696/po-wgraniu-cm11-paski-na-szarym-ekranie-481605/ , however it does concern the S6D27A1 and I'm kind of confused now... as it seems to work (at least it does for one-two hours since I loaded the new kernel well... for sure I WILL BE CONFUSED if it woud work longer than one day without "black screen bug" since I am pretty confident that I have WS2401...
Maybe I do something wrong while checking the driver, etc?
One way or another the device drivers available in the filesystem are in :
/sys/devices/pri_lcd_ws2401.0/subsystem/drivers and I have there
pri_lcd_s6d27a1
and
pri_lcd_ws2401
so... since the ONLY driver entry in /sys/devices
is pri_lcd_ws2401.0
it suggests that I am using the WS2401 one
Anyway... I will post later some more info on this
Ok, it seems to work fine - no issues so far. hail to PolishVodka!!!
P.S. However I thought that the kernel from http://forum.xda-developers.com/galaxy-ace/ace-2-develop/kernel-ace2nutzer-kernel-20141027-t2920365 will be working fine, unfortunately for my WS2401 still the "black screen bug" ;/
Im thinking it may be the firmware cuz installing cm13 broke my GPS. lock utility apps aren't seeing a single satellite I'm wondering what the best way to fix this would be
Wait for CM13 to be stable.
Builds are now experimental and a lot of features have to be polished before it can be a stable release.

firstly, why do you bother posting... nothing you said makes sense.
They fix basic functionality in nightly builds they don't save the fix for a stable release the reason they release nighties are so people can find issues and resolve them by submitting bugs and logs to cm team and/or discuss issues on forums to brainstorm solutions... i literally was only asking if someone else had already found a fix for it, sometimes there are simple fixes you can do in seconds like alot of video glitches in nightly builds can be fixed by changing video settings in dev options.
second, cm 12.1 doesn't even have a stable release yet so ur asking me to wait several months , if everyone had that ****ty attitude nothing would ever get fixed.
thirdly, i didn't say i was surprised something isn't working when the first nightly was released on the 25th there is obviously going to be issues but the people who are running it already are the ones trying to advance the releases to stable by using the report to CM team feature on the phone from the earliest nightlies to provide them with information to do the polishing you speak of, so why say something like that? it just doesn't make sense. If there are no fixes available (which is why i posted to see if anyone has one) then maybe i'll spend some of my time troubleshooting it... not that i'm a pro engineer or anything but i've found fixes to issues before, plz don't tell me to wait for stable, again if everyone had that attitude there would never be a stable release.
I'm having the same issue on my d852 with the latest CM13. In the d855 cm13 thread someone posted a flashable zip that fixes the problem for them. All it contains is a modified gps.conf so it's safe to flash on our d852. It didn't work for me but it may for you.

I have been out of the loop for 3 years, since last flash. I did a half root thing where certain camera modules weren't touched, is this still a thing? Also I have no clue what this purple notteamwin is
What rom would you recommend me for best physical button snapshot machine?
thx
Edit, I run this odd traffic series blog 1picaday. berlinwaiting.tumblr.com Today nopic due to bootloop, tomorrow maybe a new shiny rom and continuity, pls xda I need guidance

Maybe this is not what you are looking for, but this sounds as great ROM
https://forum.xda-developers.com/sony-xperia-z1-compact/development/rom-t3657384
( I didnt test, just reading the thread )
the rom JIJOK mentioned, is very good. I am using it atm. But "half root" and "noteamwin"... I think you should read the threads very carefully. At first get real recovery (Sony EMMA Tool) and TWRP (yes team win).
Ever since I updated to Nougat I've been experiencing lags everywhere. Can't play videos on mx player as it slows down and then speeds up. Even unlocking my phone takes 3-4 seconds after touching the fingerprint scanner. I have not rooted my phone or unlocked the bootloader.
Please help.
This is a common bug in official P2 Nougat software. There are several threads about it in the lenovo-forum (https://forums.lenovo.com/t5/P2-P2a...and-Whatsapp-still-have-problems/td-p/3642232)
Official devs and admins know this bug and are "looking into it" for nearly a year now - no response, nothing. The nougat software is just not finished and will never be finished.. You need Android 6 to run the P2 smooth.
I do not know if this bug also occurs in the custom roms - maybe someone with those lags/stutter in offical nougat who switched to custom rom can confirm if they are gone
