The phone is charging, but the computer does not recognize the connected device

If the device is connected and the device's battery is charging, but the computer does not detect it, you should try the following:

connect the device through another USB port on your computer. If the other ports on the front panel give the same result, try using those on the back of your system unit;
use another USB cable to check if the problem is a damaged cable;
Check the cable connector on your device. Damage to the connector is a very common cause of problems with connecting a device;
connect your phone via USB to another computer. If it doesn't work, the problem is in the phone. And if it does, then it’s worth checking the settings of your computer and, in particular, the USB connectors.

To check your computer settings:

The device connects, but the internal memory of the phone is not displayed

The device connects, but there are no certain files or photos

One of the reasons that files are not displayed on the connected phone may be problems with the memory card:

try inserting the memory card into another phone and connecting it;
make sure that the memory card slot is not dirty or visiblely damaged;
remove and reinsert the memory card into the phone, then try connecting it again.

And also the reason may be some applications that have changed the standard location of files on the phone. For example, the QuickPic application can lead to just such a problem. You need to find out where the photos are stored now and look for them in the appropriate directory. You can usually find out the new location of the files in the program itself that moved them.

If the smartphone does not turn on for another reason, then this is a separate problem that can be helped by restoring the phone’s firmware. This can be done through the phone manufacturer's program, if your device model has such a program. For example, the program Kies Samsung for Samsung phones or LG Mobile Support Tool for LG phones.
