Samsung S6 with clear cover
So far the only sweet spot I can find for Samsung S6, with the clear cover. Able to unlock with one hand most of the time (with exception of a few locations, especially that one spot at the undergound subway... * grumble *).
In case someone is wondering about the clear view cover - Nope, the S6 can't read the NFC ring through that cover. It is slightly thicker than the clear cover.
Edit: old thread is old, didn't see that.
