This is probably some sort of phone 101, but can't figure it out on my new Galaxy Ace. I downloaded a few apps from Google Play (Instagram, BBC news, etc.) and I thought they automatically appear with all your programs -- then touch and hold them until they transfer to your homepage. Have already done this successfully with a few apps... Problem is, all of a sudden they're not appearing at all, though they're definitely downloading and under my Application settings -- just can't figure out how to run them! Step by step help would be HUGELY helpful, and I can't seem to find any one having had the same problem on different threads. Thanks!
