Of course this info should be included in the op but here goes..
Modded Google Play store is an modified version of Google play, that is similar to original app in design, appearance, download speed etc but it has some unique features such as:
Successful License Verification:
Whenever you download an paid app from other sources than Google Play it checks for license and as you wouldn’t have license, you couldn’t use that app. But now, with Modded Play store you can easily use those apps as this modded app verifies License of any app and without Internet connection too.
So, you no longer need to remove License verification with Lucky patcher.
Disabled Auto updates:
Modded Google play store never auto updates.
If you download an paid app from google play you can refund your payment within 2 hours and paid version of app will be uninstalled from your device but with modded play store your money refunds but app also keeps installed.
Remember:-
1)You CAN’T download paid apps for free directly (still you can use refund trick) and its NOT applicable in billing that means You cannot hack in-app purchases with it.
2)YOUR PHONE MUST BE ROOTED.
