FIX to android.process.media
Hi to all...
After having a great upset about the hangs that occurs when managing ringtones or notificacion, and reading lot of posts with no help I decided to post the way I fix my issue with the android.process.media error.
It seems that it's caused by an error when this process tries to access to the media stored in the device just for a ringtone, a sound of the camera shutter or the sound of a whatsapp notification.
My S4 is in Spanish, hope to make myself understand.
What I did was, going to Settings/More/App Administration/Swipe to ALL/ and search for "Media Storage". Entered and push button "Erase". This way you erase all data about ringtones, notification tones, etc. REBOOT.
Then, you must download from Internet the Default S4 Ringtones (Google knows) and place them in /sdcard/media/audio and Reboot again.
At least it worked for me. Thought I had to restore to default and it really pissed me off.
