Most phones currently in production have a feature to block access to data that you consider confidential, not intended for prying eyes. You can set a password in your phone settings. If you forget it, you can easily restore it using a few simple methods.
Instructions
Step 1
First of all, check with your cell phone manufacturer. Request codes to reset the firmware and to return to factory settings, as well as a standard phone lock code. Use the code to return to factory settings, and then either disable or change the phone password using the received code.
Step 2
Also, you can use firmware reset in order not only to reset the password, but also to get rid of all information that is not systemic - your personal data, phone book, multimedia, application, i.e. all the data that you have saved in the phone memory.
Step 3
Moreover, you can reflash your phone. By flashing, you can not only change the password and erase all personal data, but also change the graphic design of the phone menu. In order to flash your phone, you need USB sync. Use the drivers for your computer and a special usb wire to flash your phone. Do not forget to keep the original firmware version, and also download one factory firmware in case the flashing process goes wrong or is interrupted. In this case, you will be insured against any malfunctions that may arise.
