I dunno if this has been posted before. I tried a search but didn't come up with anything (The esato sql-db has grown REALLY big).
Nonetheless. Use a light coloured theme on your phone and set your contrast slider ALL the way to the left. Things may darken, yeah, but if your using a light coloured theme u should be okay. Now check the quality of the pics from your mca-20 in mypictures.
I sure hope it works as well for u as it did for me.
