download app from play store SGS secret code and select option hard reset this can help to sort out the error but take a backup before selecting this option
I had the same problem.
I fixed it as follows.
1. do a hard reset
2. change the wallpaper - should be not so colourful. I got best result with a bluish wallpaper.
3. reducing brightness.
4. do not change the font size
5. update flash
6. I currently use only the available apps. only skype and facebook has been installed
7. do not use a pocket. be careful that your tab gets not too hot. Well, I live in Sri Lanka now. So we have 24 hrs long around 30 degrees....
Now it works again without trouble and I do not know why. Regardless, it works well
i am having even worse situation, my galaxy isnt even allowing me to do any installation. when i start, screen comes with flikering and its not getting stop or just got Black !
what should i do in this situation, any suggestion. i dont know how can i do hard reset. is there any option !
