since i have updated my note 3 to 4.4.2 its giving problem with micro SD card, developers did find the solution which works in most of the applications specially in Titanium backup. I use GoBackup Pro to backup my messages, wifi access points, call log, launcher layout etc. gobackup do not read memory card straight away. i have to use root explorer and and change permissions of /mnt/media_rw folder to rwxrwxrwx. I have to do it every full restart because permissions go back to rwxr--x--
any comment or help?
