I am using android phones from last 5 years. I observe and analyze the all stages of Play store. Currently it is very advance and updated shape of it. Google play store has houshands of application. It covers all type of application categories.
There is free as wll as paid application avaliable for users. But there is a lag in this store. There is some fake or spam or apy application which are available on store. Google should banned this tyoe of applications. Over all play stire is the hear of any andriod phone.
