Two weeks ago i got my S3 und updated it with Windows update. I have only Microsoft software installed. Problems: 1. The micro SD card and the USB port interfere with each other and it is not possible then to the access the SD card. S3 hangs and cannot be shut down. Blue screens also happen. 2. The first start of S3 fails. At the second start high and width is changed (the screen is rotated 90 grad in laptop mode). 3. WLAN connection problems. 4. Sometimes S3 cannot be shut down. Any suggestions?
