Apps My Playstore app's getting a lot of uninstalls?

[crimsonscythe]

I recently built my first app and published it on the playstore.
It uses the proximity sensor to turn on the screen when a finger is hovered over the sensor. Out of 47 total installs the app only has 14 current installs , although it performs its function and does what it is supposed to . To ensure the service isn't killed I have kept it in the foreground state meaning there is an uncancelable notification too. A few users requested removing the notification , and so I did in a new update just yesterday thinking it might be the cause of the uninstalls. The stats on the developer console haven't yet been updated so I can't see whether the removal of the notification has halted the uninstalls or not , but I am skeptic.
Why would users uninstall it and would could be done to prevent it?

P.s , On some devices an led light is also visible since the proximty sensor stays on, as one user reported, but I can't do anything about that and it doesn't show up on my htc wildfire s , maybe slightly in the dark but not much.

Just be patient and do focus on your App Store Optimization (ASO) so that you can be able to target your desired audience. The major reason of rapid uninstalls are due to visibility of your app on irrelevant keywords, some users who find your app while searching keywords on Google play store may install your app but when they don't find what they were searching for then they immediately uninstall that app, so always try to focus on keywords that are related to your app and do ASO for those keywords on Google play to get better results.
