1.Go to the market and get an app called 'Spare parts plus+'. This is a huge enhancement of your settings! You can change transition/window animation speed, wifi sleep policy to save battery and much more. 2.Get an app called 'noled'. With this you can get low power notifications on your screen when the phone is locked. The SGSII has an AMOLED screen which means that Black things use no battery at all so this app displays a tiny colored dot on your black screen when you get an email or text or whatever you set it to. You can customize for them to be different colors. This is a replacement for the LED notification light that many phones have but the SGSII lacks. 3.In the gallery pinch on a folder/collection of photos and prepare to be amazed by a dazzling 3D effect!
