How to do Android password backup

It’s possible that none of the options above got you passed the lock screen. Luckily, some of our readers struggling with that issue were able to find even more creative ways to bypass their lock screen and were so kind to share them. We’re extremely thankful for that!
We haven’t tested them throroughly on multiple devices or Android versions, so we cannot promise that those will work for you. However, a number of people managed to access their phone again and we hope you’ll do so as well.

1. Call your locked phone from another one.
2. Accept the call and hit the back button during the call
3. This should give you complete access to your phone
4. Go to your phone’s security settings and try to remove the pin or pattern. To do so, you first need to put in the current one, which you obviously don’t know anymore. The only way is to guess and try out different combinations until you get it right. Should you get this far, then you can disable the pin or set a new one.

Zubairuddin’s very creative method can help you out in case you’re Wifi and data connection are both turned off. As mentioned above, this method might only work on LG phones, since it relies on LG’s native quick memo app.

1. Press and hold the volume up key, until the Quick Memo app launches.
2. Draw something random into it.
3. Tap the sharing button and select SmartShare.
4. Selecting SmartShare should activate your phone’s Bluetooth and Wifi (important here is Wifi).
5. Make sure you’re close to a Wifi network that you’re phone connects to automatically.
6. Now, you’re back online and you can go ahead and try all the methods discussed above that require a data connection.
