I have been using the Samsung Galaxy S3 from past 3 days and I simply love it. It looks like my Galaxy Note will be in the drawer for coming few weeks for sure. Anyway, there are some annoying and some not-so-annoying bugs that have discovered so far in my Galaxy S3, that should be common to all S3s out there. So here they are:
1) Since I got the white one (which is the only one available right now), I need to be extra careful while holding the phone as the back cover is very smooth and it might fall if you develop sweat in your fingers
2) This one is a biggie. No USB storage mode, which is one of the most strong points in getting an Android device instead of an iPhone or WP7 phone. Data is transmitted in either MTP or PTP mode, which means you cannot use your phone when the data is being transferred.
3) It would be pretty much impossible or very difficult to get custom boot animations as it uses the proprietary QMG format made by Samsung.
4) If you were using an Android phone with real hardware buttons earlier, you will find yourself accidentally hitting the soft keys.
5) Waking up the phone is not always instant.
About the MTP issue – While the main advantage of using MTP for file transfer is the ability to use the phone and the SD storage when the data is being transferred, you cannot do the same with the Samsung Galaxy S3. No buttons work.

Explanation: Like other Galaxy-branded devices, the GS III uses EXT4 as its file system (FS), which is the default FS in Ubuntu. Since mass storage mode works only with NTFS, FAT32 and resilent FS, Samsung decided to use MTP for making the storage card accessible in Windows machines. Another disadvantage of using MTP is that latter is much slower than USB 2.0.
Update – The solution is here. Thanks to folks at XDA, the Galaxy S3 mass storage mode can be used by using an app.
