my iPhone 6 plus screen is enlarged and locked. I cannot unlock it or shrink screen so I can unlock it with number pad

wOw! Thanks. I thought I was going to spend another long episode trying to figure it out online and this suggestion was the first I saw, and it Worked!!!

Thank you for a direct and precise instruction.

Double tap your screen with 3 fingers. You have zoom enabled. To avoid this in the future. Go to Settings > General > Accessibility and turn zoom off.

this worked perfectly! You saved me from doing a restore! thanks

Thanks so much. Should have remembered the KISS principle!

Glad to help......
