Not able to mount my android device on linux

Check if there are udev rules for your device

Open mtp udev rules file with vim /lib/udev/rules.d/69-libmtp.rules and search for the product ID . If you can't find it, you have to create a custom entry in /etc/udev/rules.d/69-libmtp.rules following the pattern below and reboot.

Open a terminal and type lsusb. Find your device in the output and note down the ID (e.g. 05c6:6765). The first part is the vendor ID the last part the product ID.

# Oneplus One

ATTR{idVendor}=="05c6", ATTR{idProduct}=="6765", SYMLINK+="libmtp-%k", MODE="660", GROUP="audio", ENV{ID_MTP_DEVICE}="1", ENV{ID_MEDIA_PLAYER}="1"

Above method can also be followed for other devices.
