I have a Samsung Galaxy S3.
For the last couple of days, it has been freezing quite regularly. I had to hold the power button and reboot, sometimes more than once. The last time I tried this, the device would not reboot. It turns on, shows the S3 logo, vibrates, and keeps the LED constantly blue. However, it does not get any further than the Samsung logo. It just keeps the blue notification light on and the Samsung logo slowly flashes blue.
Can someone help with this?
