When you purchase copy-protected music or videos online, your smartphone downloads certain DRM (digital rights management) licenses that are necessary for decoding the downloaded media content. Without the proper DRM licenses, you cannot watch or listen to the downloaded protected media. But since you have paid money in exchange for such DRM licenses, you should better protect them when selling your old smartphone to someone else or giving it away for free. Before you give away your Android smartphone, you should delete all the DRM licenses stored in it in order to prevent their misuse by someone else.
Here is how you can reset or delete the DRM data in Android Lollipop:
- Open the Android settings by touching the menu button when you are on the home-screen and selecting Settings or Android Settings.
- On the settings screen scroll down and select Backup & Reset option from under the Personal category.
- On the Backup & Reset screen, select the DRM Reset option and select the same option again on the next screen that opens.
- You will be asked for confirmation, and you should choose OK to proceed and remove all the DRM licenses stored on your smartphone storage.
Conclusion: DRM licenses can be easily removed from your Android Lollipop smartphone and this way you can make sure that your purchased DRM licenses are not misused by anyone else when you are selling your old smartphone or giving it to someone else.
