I got my Galaxy S GT-I9003 three weeks ago and I already have many problems with it! it's going crazy.
In the first two weeks I noticed that the phone randomly turns off. It happened like four times but I ignored the problem. Everything else was fine and I loved the phone.
This week though, my phone has gone really mad. First it freezed and non of the bottons would work not even the power botton. I had to take the battery out. This happened a couple of times.
Second problem, I frequently get the force close message for all the apps and I have to restart my phone to get it to work again (sometimes I have to pull the battery out cz the power botton does not work). This happens almost every two hours for the last 3 days.
Third problem, the phone turns off by itself or restarts randomly!
Fourth, yesterday it died once I plugged it off the charger and I had to charge it again :'(
I tried downloading GO launcher to solve the force close problem but it didn't work.
The RAM is normal, signal is good, never dropped the phone or anything. I do not know what the problem is! is it a hardware of software problem?
