There isn't a problem...but eventually it will come off. I still have the OEM screen protector on on my tablet but it is starting to get dirty on the corners and does not stick very well. Have to be careful if I don't want it off.
I returned a archos 7, because the touch was not responsive, found out it was because of the screen protector, I traded it for this great s7 and the screen protectors I couldnt return from the archos fit perfectly on the s7, and no problem with the touch sensitivity like i had with the archos.
The one I purchased for the S7 was the ZAGG Invisible Shield. It was hanging next to the display at Best Buy. It was $24.99 + $8.00 installed. It is made specifically for the S7. There is some resistance with my home made stylus but I got used to how much pressure to use pretty quick.
