The reason why Xiaomi became popular is mainly due to the fact that the company produces relatively inexpensive smartphones but can offer quality and specifications not necessarily low-level. Xiaomi has found its balance in providing affordable devices with hardware that can compete with higher-end models, and many users are discovering this truth by doing real bargains in buying Chinese OEM terminals.
This is why it is not surprising that the Team Win Recovery Project, or simply TWRP, is supporting more and more Xiaomi devices officially. TWRP on the other hand is the most used custom recovery in the world of modding Android, allowing to install ROM and various mods to personalize your smartphone in an extreme way. The TWRP recovery, thanks to a touch interface and a really intuitive way to use, in recent years has taken the upper hand on the most famous ClockworkMod which now seems to belong to the past.
Therefore the popularity of Xiaomi with its entry level smartphone has brought the interest of the TWRP team that after making its official recovery available for the latest Redmi 5 and Redmi 5 Plus, now he dedicates himself to the champions of popularity (in India have been sold olter 5 million of specimens) Redmi 5A, Redmi Y1 and Redmi Y1 Lite.
Well maybe someone prefers to have the quality of Xiaomi only in hardware and design but not in software and therefore would prefer to give up the function offered by MIUI perhaps by adopting a ROM with user experience more similar to that of Android Stock. Well if you're one of those now you can hack as much as you want thanks to the release of TWRP and install a custom ROM maybe on an AOSP basis. Well good modding to everyone.
