There have been many complaints from users of various Tecno smartphones about a pop-up on the screen that says, “OTG connected, Go To Settings to turn OTG on” when no USB device/cable is connected to the phones.

While the root cause of this bug is still unclear, a Tecno Spot member has seemingly found an unofficial cause and solution to the problem.

Tecno OTG and USB Connection error

Apparently, the problem is with the charging port. Either it got wet or moisture accumulated in there with time. We’d advise that you visit a Tecno Service Center (Carlcare) for them to have a look at it, but going by the responses in Tecno forum, you can as well do it yourself.

Note that by going this route, it’s at your own risk, but if you don’t have the time to visit Tecno Carlcare for a fix to this annoying pop-up, follow the steps below:

  1. You’ll need to have methylated spirit. For men who shave, your favorite local kinyozi has some, if you don’t have it, but be sure to ask them for the undiluted version (yea, some do dilute it to increase the quantity). While at it, get a cotton earbud too.
  2. It’s likely that the charging port has accumulated dust over time. Simply blow it out with your mouth.
  3. Dip the cotton earbud in the methylated spirit and apply into the charging port. Scrub gently through the inside several times and then let the phone dry out in the sun for about 10 minutes.

Allegedly, the methylated spirit helps evaporate any moisture trapped within the charging port and in the process fixes the OTG Connected issue. It’s also good as a rust cleaner, just in case your device’s charging port is rusty.

As noted, the above process worked for the original poster and several others who went this route but don’t come for our necks in case it doesn’t work for you.
