Re: Pausing issue
Check that he has the latest OS Version on his phone. The version can usually be found at Options>About.
Navigate to the correct device specific forum on this board and in the 'Attention' section the latest OS will be listed along with instructions on how to update.
Another piece of advice; it may be worth defragmenting his Media Card in Windows to ensure that the data is organised as this may cause this kind of issue.
