I still occasionally open to a "white screen" which is corrected by tapping the home button.
I have cleared cache, and storage in settings shows the following:
Internal storage: total 2.09 & Available 1.55
Phone Storage: total 9.93 & Available 8.78
Total Space: total 12.96 & Available 8.9
Seems like I have adequate free space, but why do I get the "white pages" when I awaken the phone?
