I have always installed xiaomi.eu firmwares, without ever flashing gapps. Afterwards, I have just installed whatever apps needed, like gmail, calendar, Google+... Is flashing gapps really needed? I am asking this since I have run into a strange issue on a Redmi 1S, running xiaomi.eu V45.0.0: I am receiving an error trying to sync google contacts. On other, non MIUI phones, I would stop the contacts storage app, delete its storage and restart it. I can't figure if I am in the same boat here. Plus, which app I should do the same thing to resync... In any case: is it needed to flash gapps on xiaomi.eu firmwares or not?
