Non pensavo fosse possibile finché non ho trovato questo post:
(These improvements will only be noticeable for lower-end android phones)
Here are some ways ive improved my Wildfire's speed
Be sure to add thanks if it helps or comment if there are any problems
Change display resolution (720*480)
To do this you have to use Launcherpro, if you dont have it install it, you can choose to uninstall it after if you want
*Update* - 13/11/2011
If you have ADW Launcher you can also do this without using Launcherpro
ADW Launcher: [Menu]>Add>Custom shortcut>Pick your activity>Settings>Display Resolution
Skip to number 3)
1) Hold on the home screen and a pop-up "Add to Home screen should appear"
Follow these step
2) Shortcuts>Activities>Settings>Display Resolution
3) After doing that you be redirected back to your home screen, with a pop-up confirming you choice press "Ok"
4) The settings icon should be on your screen, tap it then pick "480p (720*480)
You should notice a speed boost when play a game like 'fruit ninja'
Basically what this has done is decrease the amount of pixels that your phone renders in the display, this reduces the need for your phone to produce higher quality images. BUT the quality of the display will not suffer, its all a free speed boost.
Peccato che questa soluzione non funzioni con la cyanogen mod in quanto manca la voce "com.android.settings.framework.app.displayres olut iondialog" da poter settare. Qualcuno sa se è possibile farlo in qualche modo con questa rom?
p.s. comunque approfitto per ringraziare tutti per il supporto, non ci credevo nemmeno io ma il mio wildfire adesso è una scheggia, un cambiamento inimmaginabile.
