Once, a friend gave me a flash drive with documents that he wrote down on a MacBook and I connected it to a computer with a Windows operating system and it turned out that the flash drive contained a lot of other information that my friend deleted on MacOS but didn’t empty the trash, and in this case the files simply moved to a hidden folder.
Therefore, it is sometimes useful to see hidden files on MacOS.
Once I changed the battery in the iPhone 5s and at the same time decided to remove dust on the camera, for this I had to unscrew the protective plate, disconnect the display and camera cables.

Below the photo, the first bolt does not magnetize, the rest are magnetized.
Once I dropped a new iPhone 5s from a knee-height onto a tile, the phone was in a protective bumper, as soon as I lifted it, I noticed that the flashlight button was not active.

For some time, I managed to switch to the front camera, but the rear one did not work.
Sometimes you could see the warning “Flash is Disabled – The iPhone needs to cool down before you can use the flash.”, But the phone was not used before and naturally could not overheat.
Sometimes also after a couple of reboots, the rear camera could start working and then again there was a black screen.
