I'm experiencing wrong colors on screen (much more saturated than stock), with color profile Natural and default smurf config. It's even more saturated than Vivid, while on stock it behaves on the opposite side (vivid seems to be stock-like though I cant confirm yet). Also the smurf config app when flashed as a system app does not have the storage permission and cannot be opened, I need to run the apk to "update" the app to get the storage permission again. 180MHz freq step does not work for the GPU, though on Pie it works completely stable for me with no boost needed.

This is a report for the latest 2.9.7-beta3 on Q though.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] pappschlumpf:
Nothing work for GPU clock, stock. Old config app copies need to be uninstalled, before flash the new one! It asks for storage perm without any problem here. Well i'll have a look to screen modes if i'm on q myself.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] replica88:
I've already uninstalled the config app before flashing the new kernel, after flashing and reboot the config app is installed as a system app and does not ask for storage permission (in app info it says no permission requested so I can't grant the permission either). Installing the apk again as an "update" to the "systemed" config app fix the issue for me as it asking storage permission properly. Something has changed for system apps on Q I guess. I have some other "system" apps from magisk module that stop asking needed permissions after upgrade to Q too, especially the storage permission.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] pappschlumpf:
Yeah you're right. Tanish, xXx and me are working on it. With Pie i tested with it works properly. On the weekend i switch to Q too to investigate and slove it. The direct settings apply does not work too atm. Tanish works on it. The script path changed with using the Magisk module, etc. Before making it final these issues will be solved for sure. Thx for report.

I was using this kernel for a while. During that time, my Snapchat kept getting disabled. Since I've gone back to the stock kernel (about a month ago), my Snapchat has remained active. So, I'm guessing it was the kernel causing the issues with Snapchat. Has anyone figured out a way to use the custom kernel without it affecting Snapchat?
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] pappschlumpf:
Probably bad installed Magisk (SafetyNet no passed) or the SeLinux permissive mode breaks it. You could switc h the kernel to enforcing using config app and reflash it. Except SELinux mode setting there's nothing from kernel side that could be related to SnapChat in any way.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] ledvedder:
Well, it had to be because of the kernel. I'm still running everything else rooted.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] pappschlumpf:
SafetyNet could be broken because of various reasons. It's not because of Magisk in general it's because of a ****ed up Magisk install. Flashing back stock install Magisk etc. pp fixes that for sure. And well as said SELinux switch may cause it too if SnapChat looks for it's status, you can change it to enforcing.

Battery life with smurf kernel is really great and solid.

Very pleased at that aspect.

One odd thing notice that if you select performance mode with ex kernel manager after few hours switch by itself to default kernel setting.

I don't know if it is normal or a bug.

On crdroid rom.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] pappschlumpf:
If ex switches back it's settings i would address that to flar2. The kernel itself does not reset settings. I used Balanced profile for a week for example and it never resetted a single setting.

But well my kernel has it's own app to switch profiles and it is compatible with spectrum and fkm profiles. I would recommend to use one of these to configure the performance modes.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] ledvedder:
This won't work on Android 10? Is that correct?
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] AnnoyingZlatan:
No but there are test builds in testfolder and in telegram grp that work on Q
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Arden144:
Doubt it. My Snapchat works fine on Android 9 and 10 with SmurfKernel
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] aLPaSLaN07:
I've came across with a config called "CONFIG_HZ = 300" in another kernel thread, for less jitter. (As if O7P is not buttery smooth anyway)

Does this kernel have this one?
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] ch@k75:
q3 test build???

Can anyone help with the proper steps;

7Pro stable Q with xXx rom mod

custom kernel

Would like to try the q3 test build of this kernel - whats the proper way to get this done?? From my above current setup?

Thanks in advance!:cool:
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] AnnoyingZlatan:
Flashing kernel then magisk then kernel should most likely work, if you want to be 100% sure, you can always flash ota zip or stock boot img before flashing this kernel.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] pappschlumpf:
Version 3.0.0t3 is in the testfolder.

Working GPU [emoji16][emoji16][emoji16], config app, etc. uninstall all copies of the config app and remove the Smurf Magisk module before flash please.

Many thx to [MENTION=1030560]xXx[/MENTION] for help and test!
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Duncan1982:
Absolutely fantastic work Erik, So So glad to be back on your kernel :good: My excitement levels got the better of me at first and was impatient, but again work is valued and appreciated....:p
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] kodrnusa:
Is version 3.0.03t also for ordinary oneplus 7? With combination with xxx.nolimts rom?
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] pappschlumpf:
Yes, still unified. But since OP7 thread is mostly a dead place i only post news here for now.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] pappschlumpf:
Magisk file replace seems to be wonky on Android 10. For some everything is fine, for others not. Well time will solve these start issues.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Duncan1982:
Well considering you not using Android 10 yet building it's pretty solid :good: I'm just using the traditional method of flashing through EXKM and all seems to be working just fine .....:good:
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] pappschlumpf:
Yes i'm still on Pie. Need my phone atm. Maybe i'll switch tomorrow.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Duncan1982:
Yeah don't be in a rush, it's a pain setting up from scratch ......:p whenever you have time, the kernel is here & functional .....:good:
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] TheGunMillar:
Edit
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] pappschlumpf:
Well [MENTION=1030560]xXx[/MENTION] figured it out, GPU OC is killed by bootloader. For now it is only possible to provide it to users using a decrypted device or users doing a clean install. It only works with flashing Pie bl. This won't be part of a public release. Maybe i'll provide community internal releases. We'll see.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] pappschlumpf:
5G model currently not supported, sorry. You can use older build, 2.4.2 for example.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Duncan1982:
Well done XxX yeah there was always going to be some bs with Android 10, I was going to revert to 9, but we will have to update eventually :p kernel is running great and besides GPU overclock is not a huge deal for me .......everything else works .......cheers Erik.......:good:
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] ztotherad:
that definitely sucks, but as long as everything else works beautifully I'm game. I've yet to update to 10, just because i don't want to set everything up again. but i greatly appreciate your support! thank you and thank you for the updates
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] dr1ver23:
I had a quick question for you. I'm on xxx 8.2 on Android 10 on an OP7P attempting to flash the 3.0t3 or t4 kernels from the test folder via magisk because they have magisk in the title, but magisk 19.4 is telling me installation has failed because these zips are not magisk modules. Should I be installing the kernel a different way, like through TWRP? Is this the issue you were talking about when you said it's working fine for some and being wonky on Android 10 for others?
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] pappschlumpf:
Just flash it like all orher kernels using TWRP! It contains a Magisk module that is autoinstalled during kernel flash, but it is not a Magisk module, it is a kernel and can not be flashed with Magisk Manager!
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] ch@k75:
Awesome, brother TY! Just wanted to make sure, will try this method now:good:

Thanks this answered my question as well - TWRP method works!:D
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] ludester:
Loaded the latest beta kernel , everything seems fine except the display profiles are not working. I usually am in sRGB mode but everything is so vibrant (reason why this bugs me is I'm a photographer and I calibrate my monitors and the colors are way too saturated on the phone).
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] pappschlumpf:
Yes, if i remember right 2.5.3a works too. After the SDX merge and a OnePlus merge 5G support 5G stopped working. The modem doesn't detect SIM cards. And yes, flash TWRP.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] KannyLive:
What is the difference?

What is the difference smurfkernel.3.0.0t1.op7_xxx_magisk.zip, t2, t3, t4? Installed T4, I do not know what the problem is, but many applications, even from google, crash. In all tests, my phone shows 30-50% less points than in the oneplus 7 pro general table. What to do? Android 10 installed.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] o0ocloudako0o:
Question...?

I have flashed the "t4" version and all is well no problems - except when I look in phone status kernel version it says it is the "t3" version? Double checked and made sure with a fresh download and a reflash and still shows up as "t3"? Any reason for this?

As always thanks in advance for all intelligent replies:cool:
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] pappschlumpf:
In my Telegram channel you find newer testbuilds and other users help to figure it out.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] pappschlumpf:
Simple, i forgot to update version string. Especially in testphase normal. You may join my channel, there are newer builds. Final is not far away, but some left issues need to be worked out before it could be final.

in the OP [emoji6]
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] jld2k6:
I'm kind of curious, is anyone else using the t4 test kernel on Android 10 and having a weird bug where their screen turns off while the phone is horizontal in certain apps? I can't use Android Auto while driving or watch full screen YouTube videos because my screen shuts off. Once in a while it won't come back on even after turning it back upright. I can lock it and unlock it and the camera pops up to unlock via my face but the screen stays off and it doesn't even try to get my fingerprint. When this happens I have to hold all of my buttons until I get into fastboot to reboot my phone. I haven't found any issues at all besides this one, which is not bad for a test build on a new version of Android

Edit: I narrowed it down to only happening while connected to a Bluetooth device

[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] rejectedjs:
By clean install, what exactly do you mean? I'll have to restore my phone to factory settings, then install the kernel? And to be on the pie bootloader means that I can't run public release 10 then? I don't really want to decrypt my device because I like the extra security that brings, but I might have to consider it to get GPU OC back.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] pappschlumpf:
Because of i don't know atm if this will ever be in a public release ask in the channel please.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] TimeFlies7:
I'm also experiencing this bug when I opened PUBG at 1st and then it kinda spread to other apps too even when the app doesn't open in landscape. I don't think is this kernel's problem. The screen still turns black even when I'm not connected to Bluetooth. I am on stock and this happens to me. I tried clean flash OOS 10 again and the problem goes away.
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] GUGUITOMTG4:
Are you aware of the Animations issue that if set to lower than 0.5 or disabled will result on many games with black screen?
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] ztotherad:
quick question hopefully y'all can answer, if i convert to f2fs on data, will that disable encryption?
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] jld2k6:
You're right. I'm currently not on Smurf kernel now and it's still happening. It's either Android 10 itself or xxx no limits. Gonna upgrade to the newly released 8.3 no limits and see if it still happens
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Arden144:
No. You need to flash xXx's no-verity zip to disable encryption
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] ztotherad:
thank you. i wasnt entirely sure.

Quick questions, what's up with the WIFI fix or nofix version of kernel? Nothing in the first post or last few pages.... Which should I flash (and I suppose android 10 is supported..?)
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] AnnoyingZlatan:
It's for the people who have issues with wifi, mostly on custom roms. Just flash the regular version of kernel if you are on OOS, you will be fine

[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] jld2k6:
It's the only option I have under the GPU section, there's nothing else in the Smurf editor app that is allowing me to configure the GPU. Is that normal on this one? If I'm confusing it as another GPU option, it's the one I normally set to the 6xx mhz choice but I can't seem to locate it

My apologies! I read that the completely wrong way and thought 675 was the max you could choose while completely missing the fact that it's default and not a choice! Thanks for the clarification

[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] jomansch:
hello pappschlumpf sadly i run into a problem using the two latest smurfs (regular and wifi-version) on my op7pro and android q. whenever flashing twrp33170, magisk 19.3, xXx 8.3 everything's fine so far. but with any smurf kernel on top of this, on bootup I get the message "there's an internal problem with your device" and the camara doesn't work anymore, and no gallery app or player app will play movies. I followed the OP, "Coming from stock kernel, or any other kernel it is recommended to flash kernel, magisk, kernel." and I have to reflash stock android 10 by local upgrade to regain useable camera :confused:... I didn't try any other kernel yet, because yours is recommended with xXx ... everything was fine with this combination on pie, but now on Q :crying:
[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] Toni Moon:

[MENTION=3910111]pappschlumpf[/MENTION] I flashed the kernel 3.0.1 over stock. I have default configuration. The screenshot of configuration app shows IO scheduler as anxiety, import done in configuration app.

But when I goto app devcheck by flar25 or kernel aduitor by garak they both show IO scheduler as none. Is it normal or something wrong at my end. Screenshot attached.

Apart from this all other settings match from configuration app to actual applied as seen through kernel aduitor.

Second help sought is configuration app has option xxx no barrier ext4 mod. What exactly it does and would you recommend it to switch on.

Thanks in advance for your support.
