Can I overclock an Android tablet through Termux? (piefed.blahaj.zone)

EDIT3: this is NOT an overclock! Manually setting a scaling governor does not forcibly increase the intended frequency range of the CPU clock! Setting the scaling governor has more to do with performance management. In my case, setting it to “performance”, it simply forces the cpu to always run at the maximum frequency as designed by the manufacturer. Further reading here and here. Thank you @nocteb@feddit.org for the reminder!

EDIT2: the tablet is rooted with Magisk ( https://topjohnwu.github.io/Magisk/install.html ) and Termux is running with superuser privileges granted through Magisk. The below command was issued after su - ing into a root shell. "performance" was echo ed into all available /sys/devices/system/cpu/cpufreq/.../scaling_governors, meaning, there are several subdirectories called policy[0...] in which the scaling_governor files reside.

EDIT: echo ing “performance” to /sys/devices/system/cpu/cpufreq/policy0/scaling_governor seems to have maxed out the cpu clockspeed! Now the tablet is snappy as hell! It’ll be interesting to see how battery drain and heat are affected by this. Thank you @tal@lemmy.today !

Say, by sending some value to something inside /sys/.../cpu or the likes. I have already aggressively debloated the tablet, but I like to experiment and I am not afraid to destroy the tablet since I bought it for 150 bucks at sale. Or pehaps there is some Magisk module that can do this?

The tablet is a Samsung Galaxy A9+.

if you can unlock its bootloader (might be possible if you haven't upgraded to oneui8 yet) you can install a GSI

:) try searching for phh treble on xda forums, the google official aosp gsis tend to not work so well on different devices

You don't need to use GSI. Galaxy Tab A9+ have unoficial custom roms. Galaxy Tab A9+(2023) [SM-X210][LineageOS][A16 QPR0] Galaxy Tab A9+(2023) [SM-X210][Infinity-X][A16]
