I’m having trouble with my HTC Sensation 4G (T-Mobile). It has been slow and bee getting slower. I was able to get back some speed by doing a factory reset and only installing, what I use absolutely daily. But still simple things like getting into settings from the notification shade took 1.5 seconds which is long if you are waiting for it and if ti shows you the home screen in between.
Now I pieced together some steps that help make this bearable:
* Turn off fast boot
* Disable ‘Window animation’ and ‘Transition Animation’
* Limit Background processing to max 2 processes
Voila, animated beauty is rather dispensable, when responsiveness is impeded. I’d rather work with my device day to day, then show it off to friends how cool it is.
