Rampage issues on Android

[MePlayingGTA]

Following links show the rampages which seem to be really difficult to complete on my Android device. Without any longer novel, any tips how to easier complete these? Maybe a failed performance by purpose to try the rampages on their alternative locations? At the moment I have completed 16 of 20 rampages and these seem to be almost too difficult. Not so bad on PC.. But on Android they are. For example the third link, that rampage is amazingly difficult because those f***g cowards always attack from behind.

This also seems to be surprisingly difficult on Android (for me at least)
