سلام دوست عزیز بررسی کردم واسه اوکی شدنش متاسفانه باید روت بشه موبایل که پیشنهاد نمی کنم
Open “ES File Explorer” -> Go to Menu
Enable Root Explorer -> Tap on Root Explorer text
Click on 6th Option Mount R/W
Change for Path “/” and “/System” from RO to RW
Navigate to /system/etc/permissions directory
Open platform.xml as text in “ES Note Editor”
On top, you will find pencil icon, click on that to edit platform.xml file
Find <permission name=”android.permission.WRITE_EXTERNAL_STORAGE” > and add one new line:<group gid=”media_rw” />
