Increase iPhone storage??

8 years of using iPhones, never had an issue. Best phones I've ever owned. And I've owned many brands of cell phones throgh the years.

Also, you want crappy phones Androids are crappy. Updates are a nightmare. And storage in many high end phones now is fixed like on iPhones with no option for increasing it, so you'll likely be in the same boat unless you go mid to low tier, and then they will be 10 times as crappy.

My advice, instead of simply bad mouthing a device. Learn how it works. Learn to manage your storage. It will pay in the end.

You cannot. iPhone storage is fixed. It cannot be modified.

You either delete files and content from the iPhone to release sapace, or get a phone with more storage.

they are crap!

Because it's full?
