My phone only charges when connected to the PC
The first thing you should know is that the USB ports on the Windows PC are working correctly as well as the cable you are using. In that case, what we should do is check the configuration of the mobile device.
If they don't work, you can try to enable the usb ports that stop working in Windows or another option is to repair my PC's USB ports when they don't work.
Generally when we connect the device to the computer via USB and it works fine. Options should appear in the notification bar to choose whether you want to use it to charge your phone or to transfer files.
It may happen that the MPT settings have undergone some kind of change, especially if you have recently rooted the device. What we will need to do is force the device to show that configuration.
For this we will need the «Developer mode» which is hidden in the phone. To enable it you have to press several times in a row on «Build number» which you can find in Settings> Device information> Software information> Build number.
My PC only charges the phone, it does not recognize my mobile
After activating the "Developer options" we will have to access it from the "Settings" menu and here we can select the "USB configuration" option. A small window will appear with several options:
- Charge this phone
- MTP (multimedia transfer protocol)
- PTP (Image Transfer Protocol)
- ISDN (USB Ethernet)
- Audio source
- MIDI
In order for the file transfer from mobile to PC to work, you need to select between the second and third option from the list mentioned above. In case your phone doesn't recognize the changes we have made to the settings, you will have to restart the same and therefore there should be no problem recognizing it.
How to connect my phone to my Windows computer
In many cases the problem is not the phone itself, especially after doing what we mentioned above. If not, the problem is Windows itself and the driver configuration.
To solve this problem from the computer's operating system. We will have to go to the »File Manager«. To do this, click on «Start» and then type »File Manager».
Here you will need to find the connection with your mobile device. It usually appears in the section “Portable devices ". But since it does not recognize the connected phone, "Unknown device" will surely appear. What you will do is right click on it.
You will appreciate that a drop-down menu appears with different options and you can try two of them: the first is to update the driver, generally not necessary because Windows 10 takes care of keeping them up to date, but sometimes this "fails" to say the least.
Another thing you can do is uninstall the device directly, in many cases it is a way to fix the problem. Simply wait for the drivers to be uninstalled, restart your computer after unplugging your mobile and once restarted, connect the device from another USB input to the PC.
Reassemble everything
In case the above doesn't work, the only option left is configure everything from scratch. But for this we need to factory reset the mobile phone, something that is generally very annoying, as we will lose all our personal information, so we recommend that you make a backup before starting.
In the case of our computer, we need to check for updates to go back to a previous version (if it worked before the update) from Settings Windows> Update & Security> View Update History.
Here you will have to select »Uninstall updates» and you will be able to choose the update that you think is causing the connection problem between your PC and the mobile phone. If you have no problems with restarting your computer or formatting. From Recovery Options> Reset PC you can do it in a couple of hours.
