I racently rooted my I9500 Galaxy S4 with CWM and I installed Wanamlite ROM (4.4.2). But I can't save anything to my internal storage. Gmail cant save attachments, Dropbox cant export, Es file manager cant create,delete folder, Whatsapp cant save images etc.... Root Manager and stock file manager can modify however. What should I have to do? I tries wiping everything then installing from scratch.
