About 10 days back I had posted the same app here. But I got atleast 12 comments and a few private messages saying my app was incompatible with their device. Surprisingly my post wasn't down-voted :-). I have corrected the issue and have updated the app on Google Play. The problem was that I had uploaded just the micro-apk and not the full apk. Below, I have simply copied the content of my previous post.

Hi Guys

While going through some flashlight apps for android wear, I saw that they were unnecessarily huge in size ( size > 5MB). So I just made one for myself and its size turned out to be 1.8 MB. Quite an improvement I think.

The app's development was quite easy. When opened, it simply sets the screen background to white and maximizes the brightness.

To start the flashlight, simply say "Okay Google, Start Flashlight".

GOOGLE PLAY LINK for the interested ones.
