It seems the last versions of Miui have some problems with apps uninstalling themselves. Look at this thread: http://xiaomi.eu/community/threads/app-uninstalling-itself.22396/ An example that has occurred for several users seems to be SwiftKey. Another example is Tablet Talk. For myself this seems to be valid to many, but not all, of my purchased apps from Play Store. Apps seems to reappear without the need to install them again if an earlier version of Miui Android is installed. I am not able to post any logs, but maybe someone else are able to. Would be nice to get this sorted. I hope I have not made any duplicate post, I could not find any other reports.
