Xperia X Compact_F5321_34.4.A.0.364_Russia_Generic 8.0.0

Great update.

Great Job by Sony. I never expect Android Oreo on a 2016 phone. But Sony is really caring their customers.

Just updated with the help of this tutorial: https://droidfeats.com/update-xperia-x-compact-variant-android-8-0-oreo-official-firmware/

After installing this firmware, I flashed Galaxy S9 Apps ported zip from https://droidfeats.com/official-galaxy-s9-wallpapers-themes-apps-port-download/

I am in love with my Xperia X. I customize my phone the way I like.
