Hello, Hamari Vaani. My name is Arjun Kumar, and I am from Saharanpur, Uttar Pradesh. I am 100% blind. I am responding to a listener who was asking about their phone, although I don't know their name. Please tell us whether your phone is a keypad phone or a touchscreen phone. **If it is a keypad phone, you can press the hash (#) key to unlock the keypad. If it is a touchscreen phone, go to Settings and look for the option to turn the screen lock on or off. If it is turned off, turn it on (or adjust the setting as needed), and your phone's screen lock should work properly. Please let us know whether your phone is a keypad or a touchscreen device
