Keep iPhone unlocked
How do I keep phone unlocked
Not sure what you exactly mean by what you have posted. Did you mean to keep your iPhone unlocked so that a passcode is not required to get to the Home Screen? If YES then you can just Turn Passcode OFF. Open Settings ➔ FaceID & Passcode (depending on the iPhone that you have) ➔ Turn Passcode OFF. I strongly advise that you should NOT do this for the security of your iPhone.
If you must keep your iPhone unlocked for other reasons then I advise that you us set the Auto-Lock to Never. This is a better alternative because you can then always lock the iPhone manually by pressing the SIDE button. If you opt for this, then open Settings ➔ Display & Brightness ➔ Auto-Lock : Set this to Never.
