A: E.g. set "AC Current Max" and "Maximum Charging Temperature" to the Max.
Q: How to get Max Speed for e.g. Highest FPS in Games ?
A: Set BIG / LITTLE CPU and GPU Freq to the Max, but avoid to use "unsafe" Freq's.
Then set CPU / GPU --> DVFS --> "Maximum Temperature" to the Max.
Now you can even cook an egg on your phone !
Q: Will my Custom A2N Settings Survive if i install Stock Kernel and then going back to A2N Kernel ?
A: Yes, as long as you don't uninstall it.
Q: Can i use your Kernel Control App with other Custom Kernels ?

Otherwise send me a pm with the screenshot and you current location (city)
Q: Why I get lower benchmark scores with this kernel compared with the Samsung kernel ?
A: This kernel uses by default Max CPU/GPU DVFS Temp 65 °C to reduce the device heat. You can buy the full version of the A2N app to set the DVFS Temp up to 100 °C to get higher scores than on stock kernel.
Q: Why the Android Battery setting "fast charging" has no effect on this kernel ? - It charges always with around 1500 mA.
A: Because it would conflict with the built-in charger control.
The default charging current of approx. 1500 mA means no fast charging by default, even if you actually see "fast charging" in the notification section. This is also useful to reduce battery stress and device heat. To charge even with higher speed/current than on stock kernel you need to buy the full version of the A2N app.
Q: Why I've to pay money for just changing kernel settings ?
A: Well quality has its price. Also nobody forces you to use this kernel.
You can flash other custom kernels or flash the Samsung stock kernel from my download site. Good luck !
Q: When we get an update ?
A: This kernel is almost 100 % stable and works very well. Also this phone is now a bit "old" and therefore don't expect frequent updates.
Also don't ask for ETA's and if you do anyway, I'll ignore.
Q: How to fix audio stutering ?
A: Increase the PM-QOS-LIT / PM-QOS-BIG Freq in A2N app in debug menu --> "Audio" section.
Q: What is the benefit of editing the voltage table ?
A: to increase OC stability increase voltage and to decrease the device heat, decrease voltage. Last one will improve performance due to less throttling ! So it depends on your needs.
Q: How much is safe to undervolt ?
A: approx -50 mV is considered to be "safe".
Q: How to Report Bugs ?
- Please DO NOT report bugs if you are:
--- using "unsafe" Freqs
--- not using the latest release !
--- not using Samsung stock ROM (based stock ROMs are custom ROMs !)
A: Open the red A2N Kernel Control demo app and check in-app-menu (3 dots) then "Debug" and then on "logcat and dmesg" if you faced an app crash or if some features didn't work.
If the phone rebooted randomly, then tap on "last_kmsg". You will find the logs in your internal storage. After that you can attach them here in your bug report, by clicking "Attach files".
