Please help me my Samsung galaxy S3 got stuck on the screen where it just says samsung and it's glowing blue. It buzzes once on a while and the power button won't turn it off. The only way I could turn it off is by pulling out the battery. Everytime I turn it back on it happens again, even when charging. I can put put it to recovery mode and download mode. I've already tried deleting cache, I don't want to have to do factory reset I neeeds everything.
