My iPhone 7 Plus is to small?

What should I do?

Get a different phone.

I'm not aware of any phones that are significantly larger than the 7 Plus. Most people don't want to hold a large device to their ear when on a phone call, which means that phone makers don't see a big demand.

Donald, we're all tired of you complaining about things being TOO SMALL - and then lying to say they are YUUUUGE. If you want a Really big phone, try walking around with a flatscreen TV strapped to your hair-transplant-filled head.

If you mean the CAPACITY of the phone is too small - they trade it in. DUH.

Go on a diet.

Buy a mobile ready tablet since you like to spend money the biggest iPad and and an apple watch.

Or maybe like me you might have to admit it is time to consider having your eyes checked to see if you need reading glasses.

Do? Do as you wish.
