How to debloat your Xiaomi 15 Ultra without root access
Please look through guide full from the top to the bottom before beginning to do anything.
Beware! This guide is intended for experienced users and not half-baked newbies.
Initially, I planned to stop updating Android at the end of 2026, following the [KeepAndroidOpen]
initiative.
However, once I found out that Android 17 would be released for the Xiaomi 15 Ultra on August 27,
I immediately decided to freeze my installation on Android 16.
Stupid dumb asses > as if HyperOS 3 wasn’t already shitty enough.
In this comprehensive guide, we will maximize what this device can do without rooting.
We are locking the operating system to the final version of Android 16 and skipping Android 17 entirely.
Doin’ so because version 17 brings too many nasty things to the table, and we all want to avoid them.
More telemetry, more rights to them, less to user, more AI slop, more unswitchable services.
Also, i’ll not post many pictures to keep post clean and compact in size.
Of course you should backup your all data first at the very begging of the procedure.
By the way, i am not taking any responsibility if you brick your phone or render your data to an unusable state.
Information here is strictly mirrors my personal experience. Take the pill only as a reference.
In this section i’ll guide you through the first kickstart of your device and describe every single setting
related to user privacy, this is the most complete guide on the old interwebs.
We can use [Nova Launcher]
for even more advanced gestures stuff,
way cooler interfact than internal Android 16 implementation can provide
Update to the latest HyperOS version because it brings important camera application improvements,
like remembering last used resolution any picture format.
Exact version number: 3.0.309.0.WOACNXM.C11. As August 2026 it is the last Android 16 based version of hyperOS.
Reboot device. Also you should update Bluetooth module and Battery firmware in appropriate sections.
Modern Bluetooth implementation in HyperOS is highly unreliable and renders difficulties when pairing with older Android 11 devices.
Keep in mind that: after each update almost all custom permissions are wiped out, why? because it is a dog turd.
