I am using iPhone 14 pro 128 gb but for me not enough so I am planning to upgrade, not i am confuse to buy iPhone 14 pro 512 gb or iPhone 15 pro 256 gb model which one can buy
If its just 256GB sufficient for your requirement then 15 pro should be good bro. otherwise consider 14 pro 512GB. Whichever storage you choose its important to take periodical backup of important data. dont trust onboard storage on any device. its always safe to have a backup.
You can create question here or at fb group bro. it will be time saving to answer at any one place. Thanks for your understanding.
