Hi, I am the happy owner of an iPhone 8. I am constantly locking and unlocking my phone throughout the day like most people. Unlocking can be done through the non physical home button but the locking part is done from the side physical button. I am concerned and this button wearing down with time (the one on my iPhone 4 sure did). Is there a way (other than assistive touch) to lock the phone by say double tapping the screen or any other quick method ? Thanks !
