I bought the S5 mini here to update it to Android 5.1.1. My S5 mini has the device model SM-G800F, with a little help from the internet I installed CyanogenMod 12.1-20150815-UNOFFIICIAL-kminilte with it. With it, my S5 mini has been running fast and stable for over a month.
The update to Android 5 is now available for Swisscom customers in Switzerland according to various internet news (a colleague with M-Budget Mobile has already been offered it for installation, but not yet for me)...
Hello allgoewer, no, my S5 mini runs Android 4.4.2, and no update is pending. But even without Android 5.0 it's a brilliant device, I'd buy it again in a heartbeat. Greetings
