The best recipe for becoming a all flop in Google Play are to release an app that's battery and memory hungry with a Slow interface. Most likely, these qualities would ensure negative reviews from the users and result in a bad reputation, even if your app have Great Designand a unique idea.Every drawback in product efficiency, battery and memory consumption can really affect your app ' s success.

You need to add a delay when activating, otherwise it won't work.In additio
