I was re-downloading Vainglory in my Galaxy A5 2015. I want to download that through Galaxy Apps because it offers exclusive rewards if Vainglory downloaded through Galaxy Apps. When I press download, it said "not enough space in device storage". And then I cleaned up my storage, deletes caches, deletes apps, moving apps to my Sdcard. I pressed download once again, it said the same, "not enough space in device storage". Vainglory sized like 1GB while my storage is free at 3.8GB. I tried to download Vainglory through Google Play Store and it started downloading. I had no idea about this. Please help me.
