As the title says, I've had it. my fathers iPhone SE (despite having 3 of them in my family) is lagging so I decided to update to iOS 12 which helped speed it up. But attempting to do simple things, that you'd think I could do easily on a smart phone in today's day and age is driving me insane. Trying to put his 2,700 photos back onto the phone, I can't do it through iTunes, because it makes them into a separate folder, not into Camera roll. The last time I did this, I went into that Album, select>select ALL> duplicate, and all the photos found their way into Camera Roll. Now that crashes the iPhone. The photo's are on my MacBook Pro, and I can't do air drop, because that's too many photos at a time. Is there ANY application third party that I can do a simple file transfer, of some photos to the iPhones Camera roll PLEASE?!
