Thanks dude. It was already set up on transferring files, but not showing up. So I changed to transferring images, & then back to transferring files. It showed up both times.
what if my device isn't showing up even on the device manager? my phone used to be recognised but now not even the device manager can show that it's charging. it's like the pc doesn't even realise there's something connected. its a Tecno Spark 10pro
Check your cable. You need a data transfer cable, not just a charging cable. Type C USB to USB 3.0(blue color on inside of connector). Hope this helps.
