I can't get android studio to see my brand new lg phone that I bought specifically for debugging. I'm really sad now as the phone is really cool but I can't debug with it. I enabled developer mode by tapping the build number list item 7 times, and put usb debugging mode on. I tried both Media Sync(MTP) and Send Images(PTP) modes with no luck. I'm really stuck without this thing working.
you should try desactivating both mtp and PTP
