I was wondering if anyone else here is having the same problem as me or if its just my phone in general. When using Vine or Instagram my front camera refuses to load. Back camera works fine. Front camera works great on its own and in snapchat but for some reason both of those apps refuse to use the front camera. It always shows its in use by another app. I have turned off everything, cleared the app cache, cleared the camera cache and tried loading it and still just a black screen. I had the GS3 before I got my Note3 and to be honest Im starting to miss it as it didnt have a single issue and Ive had nothing but issues with my Note3. I love the battery life but all these little buggy issues are killing it for me.
