Two photos I took of the stars using my LG G4 smart phone on manual settings (basically gives you lots of settings to play with, such as white balance, exposure time etc).
The first photo, which you can see far more stars in, was a 30 second exposure, but there were a few wisps of cloud that showed up in the photo.
I reduced the exposure time to 15 seconds for the second photo and the clouds stand out less but you cannot see quite as many stars.
Photo taken in the Ashdown Forest in East Sussex, England back in March 2016.
