At the moment I have a rooted Samsung GT-S5570. After I rooted it, I noticed that it started to be slower than it used to be.
I have had this phone for over two years. I update my computer's operating system once a year. I am thinking of doing something similar with my smartphone.
At the moment I am running Android 2.2.1. I think that an upgrade would not be ideal due to old hardware. What is the best option? To reinstall Android 2.2.1 or upgrade to a newer version?
In either case, how do I do it?
