[Xiaomi Redmi Note 4 Guides, News, & Discussion] psi.singh03:
Redmi note 4 (Snapdragon) aka Mido, is a beautiful smartphone with great features from a very good 4100mAh Li-Polymer battery to Hi-Res Audio support and much more. But to experience it's real and completely unbound performance,a custom software need to be flashed as OEM's software is coded with nothing but prohibitions that help boost the battery and don't know what at the cost of features we must have. In this thread, everything is explained to make most of this device except the procedures of unlocking bootloader/rooting/flashing custom recovery etc. Better get basics done first!​

So let's Start.

Best Pie Rom Available: DotOs Roms

Why= Fully Stable with amazing battery life & native Gcam with no Root solution added. Purely Stock with a very-very nice UI. Can surely be used a daily driver Rom!

Decorating the System software with addons​

:::::Addons::::

Audio Mods (For Enhanced Audio Output)​

1. Dolby Atmos (No Ports available for Pie as on today/full compatibility with Nougat)

2. Dolby Digital Plus (Ports Available. Google it/lots of helpful videos available on YouTube)

3. Viper4android (Detailed below)

4. Ainur Sauron (don't think you need this on top of V4a)

5. Ainur James DSP (V4a has it all)

5. Maxx Audio (Never tried on Pie nor interested to)

6. DTS (causes system crash/random reboots/kernel specific/not something to cry for)​

::::Flashing Viper for Android (v4a) in Pie::::

Previously, I had to go to the download section of Magisk to dowload and flash this audio MOD systemlessly(the beauty of Magisk). That is still convenient but since Team DeWitt's Viper App has come, the process of flashing v4a has become so easy as installing a regular apk. Really, its way better now. But as promised, both the ways are detailed below?​

1. Flash using Magisk Dowload section.

For this, just touch into Magisk's Download section> search or scroll to Viper for Android>install> and then hit reboot>Done! V4a Installed!

2. Install as a normal apk>authenticate popup for installing driver>hit reboot> Done! V4a installed!​
