ok so I removed my 64gb kingston SD and literally all the crashes and erros went away! this is directly an issue with the SD. only things not working is the likes of snapchat taking videos and playing back videos, videos on facebook etc
does anyone know any more regarding 64gb card causing all apps to crash etc
Gotta be something wrong with your card. I have a 64GB Samsung Pro (class 10) and don't have those issues. It's even better than the 32GB Samsung Evo I had previously, which I think caused its own fair share of crashes.
