I recently bought a nook android tablet (not samsung). In the last few days I can't download or update apps. They are listed only as update pending. In addition, the key to pull up open aps does not. I have force stopped the play store and cleared the data and cache, as well as done a soft reset. I want to do a hard reset, but am hoping not to lose games. I am using an sd card as adoptive memory. Will it be erased by a hard reset? Can i remove it without losing data?
