Yesterday my kid was using YouTube on my OPPO A3s to help solve an assignment. However, it wouldn't take the OPPO A3s pattern unlock when I tried opening the phone. Maybe the kid has accidentally changed the lock, but I don't know what to do. Please help me.

Locked out of your OPPO phone? Forgetting or accidentally changing your password is common, but it’s not a big issue. In this article, we’ll introduce the best OPPO A3s password unlock tool.

There are several ways to unlock your OPPO device, with solutions that work 99% of the time. We recommend Dr.Fone, an expert Android tool that’s safe, secure, and ensures no data loss.

Part 1: 3 Easy Ways to Remove Your OPPO A3s Lock

Google Find My Device is an inbuilt feature in OPPO phones to unlock your phone through Google accounts. You can utilize it to unlock the OPPO screen lock. However, you need to know that you will lose all your files on the OPPO phone after the OPPO A3s password unlocks. Therefore, make sure to back up your data before proceeding with the following steps:

  • Kindly select your device, and tap the “Erase Device” option.
  • Type your Google account credentials once more. Then, click the “Erase” symbol to begin the unlocking system. That will remove the pattern lock from your OPPO, and you can open it without effort.
