One of the biggest problems of users who buy from external stores is the presence of the Chinese ROM on smartphones. Without the necessary modifications (maybe the use of one VPN) Google services cannot be used on these devices since they do not exist in China. In fact, at least for now, Big G has no power in the motherland of Xiaomi. The big world of MIUI, not everyone knows, has its own usable store so much in China so much here with us; as well as the Google Play Store he is adapting to 64-bit apps. Indeed from today 64-bit apps are downloadable from the Xiaomi App Store.
Xiaomi App Store like Google Play: support for 64-bit applications
After the great controversy generated by the "Huawei" case and its veto on Google services, Xiaomi seems willing to improve its app store, i.e. Mi Market, and that's why you are "Aligning" with the standards to which Google Play has joined this party for a year.
In fact, it's since August of last year that Google has imposed that all the applications of the Play Store have one 64 version as well as a 32 bit version. On November 28 last year, WeChat has launched a 64-bit Android beta on its official website with version number of 7.0.9. Thanks to the continuous development of smartphone hardware, now the format a 64 bit has become a standard. Also Apple Lossless Audio CODEC (ALAC), in 2013, it introduced support for 64-bit applications on the iPhone 7S A5 processor, despite not abandoning support for 32-bit applications until iOS 11 in 2017.
This move makes it clear how, in addition to the development of MIUI, Xiaomi is very interested in giving the support for all third party apps. Never let one day create such a big market from challenge Google?
