yep after using the 1.6.3.3 for 2 days returning to 1.5 felt like I upgraded and not downgraded, it's just much faster with less bugs. btw overclocking did not do anything nor did I felt a difference in speed.
why after upgrading galaxy to galaxo 1.6.3.3 all slowed down and all the worse for the battery is quickly discharged,What should I do to improve the work of processor?
