How to fix
Android Boot Loop on Samsung Galaxy
on Windows

I’m using Samsung Galaxy S3 for more than a half of the year. However, for the past week, it keeps rebooting. Sometimes, the loading screen gets stuck, so I have to remove the battery and then try to turn my smartphone on. However, it is always rebooting on the loading screen so that I couldn't do anything. Could you please tell me what I should do?

A brand new Samsung Galaxy is not very likely to get stuck in boot loop unless it would have some factory infringements. However, the smartphones that have been used at least for several months can refuse to start normally. Many people reported various Samsung Galaxy versions for getting stuck in boot loop during loading, updating or flashing. Specialists refer to this problem as an Android firmware glitch, which is usually triggered by rooting, flashing, custom ROM installation and similar procedures. Typically, the phone gets stuck on the Samsung logo or phone model number screen and remains there for an indefinite period. If the phone user attempts to restart the system, the Samsung Galaxy remains stuck in the Android Boot Loop and needs to get fixed. There are several methods that can be performed manually by the smartphone user himself/herself. If, however, none of them would help, it’s advisable to take the Samsung Galaxy to the professional technician.
