Samsung’s Galaxy series is one of the most popular series but the popular series didn’t come perfect. The Galaxy series (all the way back to the original Galaxy). One of the most common problems that are faced in the Galaxy phones apart from screen burn ins is a problem tat ends up erasing the IMEI of your device. Back in the Galaxy S3 days, this issue was caused by the incompatibility with basebands.
