I`m actually using using both mobiles...
Samsung Galaxy S4 (GT-I9505XXUGNE8, Android version 4.4.2., core version 3.4.0-1567293) Samsung Galaxy S5 (SM-G900FXXU1ANE2, Android version 4.4.2, core version 3.4.0-1539356)
On S4 recording works over Bluetooth (both sides) but on S5 I hear just the buzzing sound.
It means, it
s not true that Bluetooth recording doesnt work because of incapability of Android. There must be something else, but what? Im eager to have the app also on my S5!
In case of need I can provide my email etc. in order to find the fix!
