How to Remove Sign Lock on Android | androidbasement - Official Site

One of the protections most used by owners of an Android smartphone is certainly that of the "segno”(Or“ pattern ”) which consists in going to configure a real sign with which to be able unlock the screen and access the functions and data of the device.

Il block with sign it is certainly simpler and faster to activate and use than locking with PIN, Password or Fingerprints. However, it may happen that you want to remove or modify this protection mode.

As long as you remember the sign there are no problems in removing it as protection because just follow the same instructions on how to put the screen lock on your mobile phone to be able to deactivate it in the same way. Serious problems, on the other hand, begin when for example you no longer remember the set sign and you get stuck on the home screen. How to do in these cases? Below we see some possible solutions.

# 1. Remove Lock with Sign on Android with dr.fone

Dr.Fone via Android is a powerful data recovery program for Android phones that also offers a "unlock screen”When you forget your PIN / password or screen lock sign. This function is not yet available for all Android mobile phone models, but it won't cost you anything to try the free demo version to see if your mobile phone is one of them. We have already seen how to use this function for unlock screen on Samsung, and the procedure to follow to remove the signed block is practically the same.

First download and install Dr.Fone via Android on your PC:

After installation this is the initial window of the program:

Click on the function "UNLOCK"And this new window will open:

Connect your Android smartphone or tablet to the PC via USB cable and click on "START”To begin the signed block removal process.

If your mobile phone is compatible with this function, the program will ask you to put it in "Download mode"That is, follow these steps:

1. Turn off your cell phone
2. Press the Home key + Volume Down key + Power key at the same time
3. Press the volume up key to enter "Download" mode

Once the device is in "download mode”The program will reset the device (without erasing the data). This operation will take a few minutes.

At the end of the process described above, if all goes well, a message like “Removal of uncompleted block“ will appear.
