The default Samsung keyboard is really a mess. The swipe is predict a wrong word almost 90% of the time. Changed my to Swiftkey, so much better compare to stupid Samsung keyboard.
Bought another unit of bluetooth earphone to replace my month old Adv.Sound Model 3. This time is beyerdynamic Byron BTA. The built quality is so much better than Adv.Sound model 3. With fixing magnet and aluminium housing compare to plastic in Adv.Sound Model3.
Sound output thru. aptX is very good. Bass is even more solid than Adv.Sound Model 3. If you listen to lossless thru. S8+ highly recommended to invest on this bluetooth earpiece.

Sound is clean and detailed, treble can be a bit forwarding and tiring. Higher end sound is crispy and full of dynamics.
And yap, the treble is the bit let down but a simple twist in setting is enough to balance it out.
