The following problem is occurring today, even though I had no problems doing the exact same thing yesterday: I have connected the phone to my USB port on my computer. The phone is charging, so there is an electric connection, however the notification saying "USB connection methods" isn't there. The computer gives no sign or reaction either. What to do now?
- I have switched cables.
- I took the SD card out today and I have put it back in.
- I tried all my USB ports already.
- The cable I used yesterday isn't working either.
getprop persist.sys.usb.config
say? Likely MTP won't be in there. If you're rooted you cansetprop persist.sys.usb.config mtp,ptp,adb
to restore mtp and ptp.
