Hello friends!
I was using Google play store from last 6 years SK I want to share my opinion about it so lets start.
When any developer can developed any application on googles specialized software i.e. Android Studio for PC then this application directly uploaded at google play store for that we needs some money.
After publishing of that app on google play store any person can download this app fro it.
All applications are fully verified by google after verification this app will publish on play store so there is no security essue on it so dont be serious while installation of any app on google play store.
You may be pay for some applications on google play store. While playing on play store you dont take tension this is fully secure. There was different ways to pay on it.
Overall security of google play store is awesome.
I recomend that application for all persons who want to full security and no bugs.
Google play store is awesome in security, update, variety and any thing.
Thank You.
