Hello I have LG G4c for a phew months and now i encountered a problem. I buyed a new 32Gb class10 sd card but when i try to adopt it as internal storage, settings app crashes. And even in moving app to sd card it crashes. But if i root my phone and use link2sd i could force it use portable storage as place to store app data.. Such as data for GTA VC and other games obb files. Is it possible? How i can solve this? This phone is quite slugish and slow. I road that i can make swap file if my phone is rooted. I have 861mb ram and if i create 2048mb of swap file it shold run faster.
