This is Light, possibly the best combo of:
Features you need (camera flash & white screen)
Small size (~40kb)
Focus (no ads, no links, no nothing)
Privacy (no weird permissions)
Short put, it just lights your way. Enjoy!

A brand new icon, material design and still an incredibly small app (actually, it just got 20kb smaller). Oh, and you can put it on your SD card now.
