Enabling Adoptable Storage on MIUI Devices

This is a dirty little trick to move apps from internal storage to MicroSD card without unlocking bootloader and no root. Compatible devices include Redmi Note 5 Pro/AI, Redmi 5/5Plus, Mi 8/EE/Lite/SE/Pro, Poco F1, Redmi 5A, and any other Xiaomi phones running latest MIUI ROM based on Android 6.x or above.

The old school way to move installed apps on the SD card was so yesterday. The complicated procedure involving bootloader unlocking, flashing a custom recovery, and finally rooting, is just too much for most users.

Despite rooting allows its users to do almost anything with their phones, the fact of painful tasks beyond its process is indispensable.

Fun fact! Apparently, Google has managed to embed an in-built system since Android 6.x Marshmallow. This system is called Adoptable Storage technology. This technology has the ability to adopt external storage media to act like internal storage (source: Android.com).

When external storage media is adopted, it’s formatted and encrypted to only work with a single Android device at a time. Because the media is strongly tied to the Android device that adopted it, it can safely store both apps and private data for all users.

That means, in short, all devices running the latest MIUI version capable to make use of the technology. This is such great news for you, for me, for us.

You can now use your external MicroSD storage as internal storage. Even better! You can utilize it as both external and internal storage although the fact it is an external one – literally.

The only obstacle here is the method. MIUI does not include the feature activated by default yet. Even worst, most of the available apps allow you to do such things only if your phone was rooted. Again, rooting Android is still not a piece of cake for half of Android users population.

This tutorial guides you on how to enable Adoptable Storage (AS) on any Xiaomi phones running MIUI 9 or MIUI 10 built upon Android 7.x Nougat or Android 8.x Oreo. As for example, this trick was applicable on Redmi Note 5 Pro/AI codename Whyred. Undoubtedly, this works perfectly on Android 9.x Pie as well.

The output of this tutorial is Adoptable Storage is enabled. The outcome is many things. For instance, you can then use your SD Card to install Apps and their data. You can also move several system apps on it.

The best part, it requires no root and no unlocked bootloader.
