I am quite disappointed by haptic feedback on my 808, if I compare it with C7 and 701 which I know.
On C7/701 the haptic feedback is much more "silent", "solid", "elastic", where on the 808 is noisy, weak, with a a "plastic" feeling.
Do you have compared them and have the same feeling? I believe that on my 808 the vibration module is to not good.
I have 701 with Belle FP2.
Touch vibrations were great with initial belle.
But with FP2, the vibrations are not good on my 701 too.
Do you have FP2 on your 701?
I've also noticed that touch vibration feedback was better on 701 with Belle than before updating to FP2 (possibly because of higher CPU speed that changed some parameters?)
In any case, haptic feedback on 701 is still better than on (my) 808.
Has been other people able to compare?
