Hi, I bought oppo A57 phone a week ago so I wanted to put a screen protector on it. Whenever I put a screen protector on it and call someone, the screen become black and I can''t turn on the screen until the call ends by itself. All call apps have the same problem. But, if I remove the screen protector, everything comes back to normal. Can anyone share how to solve this problem? Thanks

In mobile phone front screen have sensor. It is placed near to speaker. This sensor attach to light. if you cover this sensor the mobile screen blank or black color. at the time of fitting screen protector you check this sensor.

Don’t go after who is promoting beacuse after you see the features properly of Lava z25, you will understand, it doesnot need any celebrity to promote it.

Kindly prefer this video link for step by step setting. https://youtube.com/watch?v=34Eu_ENgcTI For Funtouch OS 3.0 and higher version, if you have set the security password, please go to Settings>Security>tap Disable the lock screen password; Then, please go to Settings>Security>Privacy and app encryption, and click disable the privacy password. After that, you can input a password to enter Set security questions, and then you can change the security questions.
