Im not talking about replacing flashlights for more important task, especially being in the great outdoors
Im just talking about maybe replacing your keychain light
I have a key chain light on my key chain...as, if I need to find a key hole, I don't ALSO want to have to aim my PHONE too, etc.
I edc a Klarus XT11 which for what I USE it for, would not be replaceable by my cell phone...in any way or shape.
If all someone uses their light for is to find key holes, or if they dropped their keys, or their glasses, etc, and just needed a little lighting right by their feet...almost anything works of course, even a candle.
I DO have (More than one actually, I do experiment) flashlight apps on my phone...and, I have used the phone as a light...BUT - ONLY if I already had the phone OUT, and, it was handy to use it that way...or I was just playing with it.
Generally, by the time you hit the couple of buttons to get to the app, and light it up...you could have simply turned on a flashlight.
Now, I might just go and program a flashlight so I can make calls from it and surf the web, get email, etc.....
