My T-mobile Vibrant is going on a year old now. Early on I was running a custom Rom just to get android Fryo 2.2. Eventually Samsung and T-mobile officially offered an upgrade to Froyo.
Many people complained about a lag on the phone and XDA was ripe with lag fixes. I seemed unaffected by the lag….
After a few months of running the stock firmware I started to notice a lag, but I was lazy and didn’t bother to go back to a custom ROM. After about six months I started to hate my phone due to lag and lack of stability.
I soon started my search for my next ROM……
