which version do I download? I see some are 9.1 and the rest are 10.7 both have [11] so I suppose they support pixel experience 11 plus and other android 11 roms, so what does 9.1 and 10.7 mean?

edit: my bad I found the answer, so 9.1 is for compatibility/legacy reasons?

Those are touch firmwares. 9.1.24 is old touch firmware. 10.3.7 is newer touch firmware. What is best totally depends on the device you have. Infos on this in the app. (Touchscreen page).

it's currently 4:30pm I ve set adaptive charging to end at 9am (starting at 9pm) and I got a notification "adaptive charging: disconnected, reverting max charging rate to 2800" when I stop charging my phone is that a bug?

No, it just reverts back charging speed as you unplug it so if you plug it again before 9 it charges at that rate and not slowly

@Pierre2324

I want to personally thank you for your efforts during the development of this kernel. After being on Android 9 for two years, last week I installed LineageOS 18.1 with Optimus Drunk Kernel, which was a disaster and caused my Poco F1 to not boot. After searching further, I came across this kernel 4.9.257.

This kernel works perfectly and allows the user to choose between touch version 9.1.24 and 10.3.7. In addition, this kernel automatically blocks some bad wakelockers.

This is a service you won't find anywhere else and this makes the kernel better than Optimus Drunk and all the others. First and foremost #1.

    Im on OP7 diwali build. Will the kernel support it? If it does, then which version should I flash? I used ngk on pixel exp and loved the smoothness. Btw the build is android 10 and when I went to android 10 folder I got confused between Q and P

    Hello. I'm using ngk for months now and the performance and battery is great. However, i tried to charge my phone overnight and now I'm experiencing slow charging when I woke up until now. Do you guys have an idea to fix my issue? Sorry for the bad english

      Okay so good news and not so good news.

      So I've lost my Pocopone F1 tried everything and couldnt find it back so I'll have to change phone. More details on that on the telegram group. But posting here for people who aren't on telegram. BTW sorry for the late replies lately, I totally forgot about XDA as most of the things happen on telegram.

      What will happen?
      I'm still working on the next update and it will be coming soon. This will be the final update for F1 / Mi8. Afterwards there may still be upstream/CAF tag updates and if lucky app updates if new features can be ported easily to F1 from the new phone I'm going to get.

      Which phone next?
      I'll be getting the Xiaomi POCO X3 Pro. NGK + App development for it is starting so if any of you are switching phone or have it already, you'll find me there. I really don't want to force anyone, but if you plan to have/have the phone or just like my work and want to support me you can do so here: https://gofund.me/743fd7b8

      Thanks everyone, NGK and its app really took another big step with the Pocophone F1 / Mi 8 devices.

      OOS Builds intentionnally prevents custom kernels from booting so no it won't work unless you subscribe to their Patreon OOS builds. Just use Q Blobs. At first android Q came with Pie blobs and then afterwards got updated with Q blobs. For the camera to work, kernel needs proper implementation hence why the two kernel variant, now it doesnt matter every single Q ROM has Q blobs.

      No more update?
      Announcement from dev in Telegram.
      2
      What's the battery life like?
      Easily 10+ hours SOT with the wakelocks blocked, all background apps limited and optimized + Servicely + Naptime + all telemetry disabled with MyAndroidTools + LineageOS 18.1. Much, much, much better than Optimus Drunk kernel and Franco.

      No Gravity Kernel 2.0 + 4.0 App Trailer

      Hey, NoGravity Kernel dev coming from the good old OnePlus 2 here! I'm a graduating student in computer science and I actually work as a programmer. I made a pretty solid kernel for that old Oneplus device and even added Energy Aware Scheduling (EAS) support to it backporting new features like Dynamic Schedtune Boosting to this old 3.10 kernel. With it being pretty much at its apogee, I need a new challenge on a newer kernel (4.9+) while keeping NGK's mindset of Performance/smoothness while getting decent battery life due to added battery oriented features.

      For those who want a to know more about my work here is the link to NoGravity Kernel for OnePlus 2.

      iaHQ9D3.jpg

      The Kernel will boot using stock (Pocophone F1) CPU & GPU frequencies that correspond to the Balance Profile when Magisk is present. Overclocked frequencies can be selected in any kernel manager app. Other profiles for battery, performance and gaming can be switched to in my app.

      ApF0jYF.jpg

      To tweak the kernel easily, here's my No Gravity app! featuring custom profiles (Battery, Balanced, Performance and Gaming). My app offers some features that cant be found in other kernel tweaking apps. You can find them lower in the thread.)

      pmhT9VH.jpg

      This kernel should work on any ROM/Ports! Since I love OnePlus and I'm myself a OnePlus 2 user, I will do my best to fully support OOS ports.
      Reported to work on: OnePlus 6 Holi Edition, OnePlus 7 OB8 & OB8 Quince, Quarantine Edition. OxygenOS devs do not support custom kernels so if you face any issues with NGK don't post in their groups, post here instead. Latest OOS may have calling issues as reported by some users.

      v0BMu0X.jpg

      -I recommend before coming to conclusion, give it at least 2 complete charge cycles and then raise any issue.
      - I recommend to use my app, franco app or EX Kernel Manager if you need to tweak the kernel further
      -CPUs since Snapdragon 845 can't be overclocked from kernel this is why it is removed

      LBRCN7g.jpg

      -Flash No_Gravity_Kernel-vX.X.zip file in TWRP (Latest TWRP Recovery Recommanded)
      -(Optional) - Clear cache and Dalvik => if you do so, Use App Optimization button in NGK App.

      • Kernel and app updates will now show up when they are released on main page of NoGravityKernel App along with device specific changelog and download buttons
      • NGK Thermal Locking Mecanism prevents ROMs from overriding a thermal selection (Mainly MIUI) (when NGK Thermals are ON only, when they're OFF, ROM will have it's default behavior)
      • NGK now boots on OxygenOS, OOS developers do not support custom kernels so if there are any issues do not report in their groups.

      1.3 Build: Welcome to Mi 8!

      OnePlus 2:
      • DDR Input Boost Toggle

      Kernel 1.3:
      • Fixed Screen Freezes
      • Updated Profiles
      • GPU min 160MHz, GPU max 835MHz
      • GPU optimisations (Governor, Latency)

      Notes:
      • Max GPU frequency of 835MHz is only reachable manually as I don't consider it fully stable. On the other side, 820MHz Overclock is stable and is used in my profiles.
      • I wanted to use relatively longer dynamic schedtune boost duration compared to input boosts so made them separate in terms of length.
      • I would recommend turning off No Gravity app toast notifications from Magisk Manager app.

      • And many more under the hood changes...

      Notes:
      • Thermal Suspend API : This is a small API I’ve written in the kernel directly (to make sure no background services are running for it) that unsets NGK thermals when screen turns off and enables them back when screen is turned back on. (This fixes some issues on some specific ROMs where screen wouldn’t turn on or phone would random reboot while device sleeps or is charging)
      • There is now a camera fix version to fix camera on ROMs with Q-Blobs like MIUI Q, so if your camera isn't working flash this one.

      Kernel 1.1 Pie Edition:
      • NoGravity Kernel v1.1 now working on Pie ROMs
      • Using v1.0 Base

      Notes:
      • This kernel uses v1.0 base so will work on both Android Pie and Q ROMs/Ports/MIUI
      • From now on releases will be separate in 2 builds: [9] and [10]. People on Android 10 should use [10] builds since it is rebased to Full Q CAF sources even tho [9] build would still work.

      Notes:
      • Profiles also have a QSTile for fast switching
      • If you didn’t already know it was only placebo/performance wouldn’t change, but don’t worry there are other ways to make performance better
      • If you want charging throttling, you can set it back on here by setting the value to N instead of Y: sys/modules//sys/module/smb_lib/parameters/skip_thermal
      • MIUI ROM/Port variants may have some issues but I didn't have much testers on those so please send logs if you have issues

      Useful stuffs

      Clean flashing a kernel:
      1. Boot into recovery
      2. Wipe dalvik/art cache, cache, system and vendor(if recovery have this option)
      3. Reboot into recovery (only needed on some recoveries)
      4. Flash latest ROM zip
      (Optional) Flash other zips like GApps, DFE, etc depending on ROM and your preference
      5. Flash latest Magisk zip
      6. Reboot into system (yes boot with stock kernel first)
      7. Reboot into recovery
      8. Flash latest NGK Kernel zip
      9. Reboot and enjoy

      Not to be confused with a ROM clean flash!
      Do not wipe data or internal storage!


      Encryption fix

      For the ones who uses an encrypted device, those steps needs to be done to worl properly with NGK:

      To those who are facing screen flicker/bootloop upon flashing NGK on an encrypted device.

      1. Dirty flash your current ROM and boot into system.
      2. change your password to whatever you want then click on "No" when it shows "Secure Start-up".
      3. Boot into recovery then flash NGK. You will notice that it will not ask for a password even though you are encrypted.


      Taking logs

      Screen Freezes:
      -Connect phone to PC
      -Run following commands in terminal:
      [*]adb shell
      [*]dmesg

      Random Reboots:
      -When the random reboot occurs press the TWRP button combo to got straight into TWRP
      -Send the pstore folder as a .zip file located in /sys/fs/

      Any runtime kernel/app related crashes that doesnt make the device reboot or freeze:
      -Use Matlog app on play store
      -Start recording before the issue
      -Stop recording after the issue
      -Send the .zip file created


      Charging:

      Okay lets break it down for yall.

      Every kernel on every device has WARM_TEMP and HOT_TEMP values which are usually always 45 and 50 respectively.

      When device reaches 40-42C charging rate will decrease more and more until it reaches about 45C where device will stop charging even if its plugged in for safety reasons. Battery must not charge when they are this hot.

      Battery thermal removal: this will prevent throttling before battery reaches about WARM_TEMP. Once battery reaches about 45C there is nothing in the world you can do. So yea battery thermal removal is still safe, just a matter of preference because if charging throttles before reaching 45C it will heat less then continue charging but if charging doesnt throttle yea it will charge charge faster under 45C but may heat more so you may hit 45C faster. So as in every other tweaks it depends on user.

      As per my tests I would get about those but that may vary for you:
      Battery temp (°C) - Charging rate (mA) tuples
      46-1800
      45-1800
      44-2000
      43-2600
      42-2800


      What else? oh yea here are some tips for you to lower temps (cause yes some of you charge while playing pubg..)

      Tips for lowering temps:
      -Turn off NGK thermals from NGK APP

      Right you all need to understand thermals first.. A lot of users are just asking best thermals, best this, best that.. there is no universal bests..

      Thermals will throttle performance depending on heat generated.. so yes there is a gain in performance when using NGK thermals because performance will throttle at higher temperatures. Why do I say it depends? Well someone living in a hot place and is getting high temps and throttling will use NGK thermals so he gets more performance for the same temperature point but there is always throttling else a phone would heat too much in the end and be really unsecure and all. That being said, if your device throttle with stock thermals then you go ngk thermals it will throttle at higher temps but in the end may still throttle and if you hit too high temps it will throttle even harder to keep temps low. For those people using normal thermals would be best since yea performance will throttle but it will prevent the phone from getting higher temps which could lead to more intense throttling. (Can also read about charging above you may want more aggressive thermals that will throttling performance to reduce heat so you can charge phone)

      So next tip:

      -Reduce Big cluster max frequency as this cluster is a hest generator
      -Use another profile than Gaming! (Performance for me is best because its less aggressive, some people prefer balance for gaming)

      All in all, try stuffs by yourself I think I did my part guiding you through all this, the best things you can do is the best things for yourself not necessarily the best for others.


      Touchscreen Tests (NGK v1.5.5):

      Spent a whole week with testers to just sit down and find the firmware to choose and then rebuild the drivers from the groud up.. but first here's an intro

      Intro:
      Small intro for everyone cause many people confuse many things..

      -Panels: We have 3 main panels:
      FTS, NVT REV1 & NVT REV2

      -Touch firmware: comes in kernel and also in ROMs but kernel will flash its inbuilt firmware if the kernel firmware checksum is different to the one already present in ROM

      -Touch Drivers: comes in kernel and those dont have numbers/versions its up to the kernel dev to make changes it those so stop asking for driver version no one can answer that precisely compared to firmware


      Tests:
      Alright now enough talking, the tests and results.

      -Panels:
      For FTS panels, using stock xiaomi drivers was fine no touch issues seem to happen since those went out.
      For NVT panels, some had touch issues on rev1 and rev2 depending on firmware used while keeping xiaomi stock drivers so below tests were focusing on NVT mostly

      -Firmware:
      We tried 3 firmware and the ones who remained are 9.1.24 and 10.3.7 since other one gave issues

      So I did incremental test builds modifying drivers for both firmware

      -Drivers:
      For drivers, as said before I reverted all changes to xiaomi stock drivers from their source. Some issues were present for some on both firmware version and different issues on both panel revisions (rev1 and rev2)
      -Latency:
      some issues was only related to latency and I knew latency was going to be better by optimizing the drivers later on
      -Touch issues:
      So based on that, I only took account of the issues present between firmware for each driver changes
      Part 1:
      Part 1 was updating novatech drivers from a CAF source that can be seen in my kernel source. So did that, compiled 2 versions again fixed some small issues here and there like firmware flashing wasnt working, touch didn't work at first and some bootup issues, anyway main thing is that novatech driver were updated a bit with less variable locking and such coding changes making the driver faster. Results after that were good it fixed some people's issues but latency wasnt perfect.
      -Part2:
      Now was time to optimize the drivers and did for both NVT and FTS (most of those optimizations were seen in previous ngk versions) but needed to add them again and add some more and see how they impact (cause not every optimizations means better results, some optimizations introduced issues)


      Conclusion:
      So in the end if TLDR
      The conclusion was that issues were fixed after some driver changes as some optimizations made them worst, 9.1.24 firmware gave better touch (mostly under load or heat a.k.a for gamers) and didnt impact day to day users hence why NGK uses now 9.1.24 drivers.

      BUT that is based on the fact that I reviewed the drivers from official xiaomi source, then updating them, then doing specific optimizations, other kernels may have different results or different ways of doing tests, thats just how I did it.

      So yea for people who wont like touch, I will send this cause I did work on it to give better touch to most users and limiting the touch issues. I still dont think its possible to have perfect latency and perfect touch due to our phone but here's what has been done..
      33
      Are we waiting for a new update? If we are going to be honest, of course we are but @Pierre2324 actually doesn't owe us anything.
      He'll release if when he feels like it, there should be no pressure from our part.
      Battery drain is not the main issue here, it depends on the rom you're using.
      What needs to be fixed is the screen freezes that occurs on any rom when the touch firmware doesn't fit your panel.
      But then again, this might not affect some people that already has the correct specific unit for that firmware version.
      How can this be fixed? Revert back to the 1.5 or release 2 variants of touch firmwares for the next update.

      Exactly, it takes time cause Im re-doing the app from scratch. There will be more features too. Sorry for the wait but it will be worth it. Im working on something for thermals too on kernel side so a lot of testing is done for that too. You are right and ngk 1.6 will come in 2 variants for people having touch issues on one of the firmware.

      To answer the other guy, cant blame kernel directly for battery drain issues. Why? Because most users dont face those. Unless it was a general issue where everyone would see worst drain then yea we could blame kernel for it but on my side I never really see my idle go above 0.9%/h on any profile even performance and I listen to music a lot screen off.

      Conclusion, dont worry yall Im still actively working on ngk + app, just that 1.6 is quite big and cant push an half baked update also quarantine is still present here but im no longer at home with a lot of time to spare on development Im back to work since a month so I work on android stuffs at night and on weekends + testing during the day.

      Thanks for your understanding. Stay safe guys and defy gravity?
