Hi there,
I need to upgrade my S4 to android 4.3 because I want to use Polar H7 bluetooth heart rate sensor.
I'm happy with 4.2.2 and would have never chagned if not for this sensor. It works only with 4.3 or better.
My question is. Can I upgrade to any 4.3 rom without doing the full wipe (have many apps and backing them up will take ages)
Can I upgrade to any 4.3 and not lose Glonass system which I heard may get lost.
Thanks in advance.
