i have Haier w627 mobile (rooted), my play store is not working. Sometime it opens, sometimes it don't , and even if it opens , i can't download apps from it. Whenever i try downloading app or game,play store crashes.
Clear cache and data for the Play Store app and see if it loads up. Additionally, if you are on Lollipop or higher you may need to grant storage permission to the Play Store Services account to make it able to download and install larger apps.
All you need to do is to clear PlayStore cache once and then restart the phone. Hope this will work
