Went back to my Sony smartwatch 3 yesterday as my X5 needed charging and these are the things I noticed.
How small the Sony screen was
Nowhere near as bright as the X5
Sony would drop bluetooth connection to the phone and lose its wifi connection.
Touch interface was glitchy.
But what I missed most was knowing that if I missed a call on my phone it would not be forwarded to the watch
I love my Smartwatch 3
But I missed the X5 not being on my wrist.
