Strange Android permissions? Should I be worried?

Hello guys,

I just bought an android device to test my apps and was surprise to see these two android permissions when downloading my love apps from the store:

1- modify or delete the content of your USB storage

2- test access to protected storage

Is this because I enabled loading apps from external source (so to test apps)?

I know that if I saw these type of permissions, as a user I would be hesitant to download such apps. I know I did not add those permissions in (unless by accident) Is the Corona SDK adding these by default? And more importantly, should I be worry?

I mostly being doing IOS games and got kind beta testers for Android until now. So I am not too familiar with Android persmission scheme.

Any suggestions will be greatly appreciated. I really do not my potential users to be scared! It is hard enough to get users as it is!

THANK YOU!
