That was 3 months ago.

• My phone is Redmi Note 10 Pro (global version) running a custom ROM (AOSP based).

• You can install KSU on non-GKI devices: https://kernelsu.org/guide/unofficially-support-devices.html. I was probably using this one, but there are multiple KSU kernels available for my device and you can probably find some for yours in the telegram groups.

Oh, so we're playin Inception at a whole world scale. Nice.

Xmanager doesn't compile the apk. I downloads the same files you have on telegram.

The main advantage of it over manually downloading the files is somewhat easier usage and update notifications.

I think you can use already maintained ones like magisk module alt repo

No, sorry. Airplane mode should stop all data exchange with mobile radio, but you should still be able to enable wifi and bluetooth while airplane mode is on.

I'm pretty sure all communication with carrier is disabled when airplane mode is on, which should save more power than disabling only mobile data transfer (in this case calls and messages still get transfered and connection with carrier is active).

Unless you completely power off the radio you will still receive calls and messages. Some custom roms come with this option, but I don't know if it's possible to automate.

If you want to save more power, then enabling airplane mode and then turning wifi and / or bluetooth (depending on your needs) back on should save more power.

That's your decision. I experience no issues with my setup, but you do what you want.

There's something interesting about mobile banking. I constantly see stories of issues with it on non-stock / unmodified software. The funny thing is that I have never had any issues personally. Until recently my banking app worked even without Magisk's dentist (and the most picky app was McDonald's). Now I have to add my app to Denylist, but that's the only requirement, no SafetyNet, no Play Integrity, nothing.

KernelSU? Hadn't heard of that one before.

It's relatively new, few months old at most and started as a joke.

Do you get proper compliancy with the Integrity API?

Have you tried KernelSU? Also if you're careful with magisk you can get SafetyNet to work, even Play Integrity API (but only Basic and Device integrity as Strong requires locked bootloader (or a really bad implementation of security mechanisms as seen here))

Essential? no.

Worth it? maybe.

Nice to have control of your own device? absolutely.

I have two devices, primary with root (through Magisk as KernelSU still has some issues for me) and secondary without root. Anytime I have to do something more demanding on the unrooted device I really wish I had root. Local terminal access, ability to disable some annoying "features" (verified app links) and multiple other things I use daily make it worth it for me.

EDIT: I saw mentions of custom roms in other comments. I have a custom rom installed (AOSP based). If I was on a stock rom (or god forbid something like MIUI) root would be a must for me.
