It's a SanDisk microSDXC 64GB. I've even popped it out n tried it on the computer thinking my sd card burnt out but it's fine. I cleared dalvik n cache... Restarted... Opens to checking sd then sd card unexpectedly removed. I tried restarting xposed bc I do have HandleExternalStorage mod. I even turned it off to try that out. I have to admit that since the beginning of receiving this phone, the access to data on my sd card has always been laggy.
So do u guys think it's a hardware problem? Or anyone else w any ideas on how else to determine if it's a hardware or software problem?
