These things are all I do with my phone. They can scan pictures of the price tag from the shelf at checkouts.
Think about the technology involved in this: I take a picture of the grocery list on the white board stuck to the refrigerator with magnets.
Having expanded the storage on my phone, I curate my photos every 2 weeks to a month. Previous to the memory increase, weekly.
It’s a good time to go through the pet photos, where you take 3-5 at the time when they’re being cute and get rid of the sub-par ones as well.
Texas summers are so hot that I would use my phone to photograph my church parking lot to determine which trees would cast which shadows by afternoon, so that my car would be shaded by then.
I do this all the time. I use the magnify function as reading glasses when I forget to bring mine. I take pics of parking spaces, and other stuff I want to remember later. A couple times, I’ve held it behind a piece of audio or computer equipment with the light on and snapped a photo so I could see what kind of connectors were available or what the serial number was without having to move it out from the wall. I have a useful little app called “Hey Camera” that lets me snap a photo with my voice, so I don’t have to hit the button. Love that app!
You win the thread. Aiming at stuff in awkward directions and not losing aim while trying to tap the button with your 6th or 8th finger is a PITA. Thanks for that tip.
Agreed. I have to get one of those. I use my camera a lot to look at stuff underneath other stuff so I don’t have to get down on my knees. I threw together a periscope so I don’t have to bend either. Probably something for sale already, but perhaps not needed as much with voice activation. I imagine those selfie sticks had remote triggers also, but the periscope is so I can view things in real time as I move it around looking under a car or dresser.
Of course I do. You don’t think I’m going to talk on that POS, do you?
My wife has very poor vision without her glasses. When She gets new frames or glasses I take pictures of Her so She can choose better.
Umm… I should probably get around to doing that someday. It’s just that there are over 10,000 pictures on my phone, so I guess it will have to take me at least two lunch breaks, maybe even three!
Having once spent 25 minutes or so tramping around unfamiliar city streets to find where we’d parked our car, taking a picture of the spot/nearest intersection has turned out to be, if not a lifesaver, a guarantee that we won’t 'lose" the car again.
Speaking of being lost, a couple of young women once pulled up next to our car to ask for directions, an episode Mrs. J. dubbed “Two Tarts In An Escalade”. A couple years later I was sitting in my vehicle in a supermarket parking lot, looked up, and just across from me were two more babes parked in an Escalade (almost certainly not the same ones). I had to text a discreetly taken photo to Mrs. J. 
If possible, it’s much easier to do any extensive file management by connecting the phone to a computer. Once it’s connected, the phone’s storage is just another folder.
I solve this by opening google maps, zooming in on my location by the car, dropping a pin, and sharing that pin via SMS to my wife. Then we both can navigate back to the parking spot.
Last time I tried to connect an iPhone to a PC ( which must have been about a decade ago), I found out it wasn’t that easy.
Well, there’s your problem. 
Seriously, for photos, it should be as simple as plugging your charging cable into a USB port on the PC. You can use File Explorer to browse the photos then. For anything other than photos, it will probably demand that you use iTunes to manage the files. (Because Apple is a pack of walled-garden control freaks who don’t want you to have power over your own stuff.)
I use my phone to remember wiring before I change a part.
Sometimes my phone can capture a screw or bolt head in a tight space that I can’t clearly see. That makes removing it easier.
I’ve taken pics of furniture that I’m thinking about buying. Look at them at home in the living space.
Phones make photos so easy. I can’t believe we used to ask drug stores to mail film for processing. Took 10 days to get our pictures.
I make phone video of unpacking the Xmas decorations from The Big Boxes That Go In The Closet. Otherwise, it’s like playing 3-D Tetris when I re-pack after the holidays.
I use my camera for shopping. I’ll snap a pic of an almost-empty milk carton when I see I’m low… then when I’m passing by a store I’ll check my phone (I made a Shopping List album) and see if I need something.
I also shop with my phone to prevent impulse buying. See a cool pouch to hold my sketchbook? Take a pic showing size and price. Then look at that the next day and see if I REALLY need it.
Oh, and sometimes, I’ll check the basement and… oh, look, here’s a cool pouch to hold my sketchbook! Glad I didn’t buy yet another one.
Am I the only one that misread this? And then thought, WTF?
