Tell your friends about your new solar charger app. Impress them. Expose your phone screen to sunlight to see how fast it charges. A virtual ampere meter will show you how much current you get. Don’t get fooled! Unless you use a real charger, the phone won’t charge even for a bit. Of course it’s a prank but your friends don’t know it yet. Compatible with S^3 / Anna / Belle Smart Phones.
