Why can't I connect my Samsung A3 with pc via USB?

[B. Diddy]

Welcome to Android Central! As mentioned above, it could be an issue with the cable or the port. If you've already tried different cables that you know work for other devices, then the port might be the problem. Make sure it's clear of debris by blowing it out with a can of compressed air and cleaning the contacts with a small Q-tip dipped in rubbing alcohol. Also see if the problem persists in Safe Mode: https://www.hardreset.info/devices/samsung/samsung-a320f-galaxy-a3-2017/faq/safe-mode/. If nothing works, then contact Samsung (if it's still under warranty) or bring it to a repair shop.

Someone should try a factory reset , see if that fixes it .

same issue

Same problem here. Everything was working fine, got a notification of updated apps over the weekend, and now I have no USB connection icon nor is the PC seeing the phone. How do I roll back to the previous version of the O/S, this is essential functionality for me to use this phone?

n.b. have tried different ports, different cables, different PC and cleaned the connector.
