So you’ve got a OnePlus 3 or 3T, but after setting it up and using it for a bit, you’ve run into a frustrating issue. This isn’t uncommon for a new smartphone, but it’s still annoying all the same, especially with a device as well made and inexpensive as OnePlus’ latest. We did some looking around to see what problems other OnePlus 3 or 3T owners were running into, and we’ve compiled a list of the most common ones, as well as what to do to address them.

Hopefully, whatever troubles are ailing your OnePlus 3 or 3T can be solved with these fixes. The first thing we recommend is to buy one of the best OnePlus 3T cases to protect your phone from damage.

Problem: Device randomly restarts

There have been people on the OnePlus forums, Reddit, and the XDA Developers forums who have reported seeing their devices restart for unknown reasons. In most cases, this occurs while browsing the internet.

Official solution:

  • OxygenOS 3.2.4 included a fix for this specific issue, but if the problem persists, or comes back afterwards, your best bet is to update to OxygenOS version 4.0.2, which further improves system stability, or to the latest version of OxygenOS, which is version 4.0.3 for the OnePlus 3 and 3T.

Potential solutions:

  • Let the phone sit until its battery is completely drained and won’t turn on. Leave it for up to 10 minutes, then plug it into its charger until the battery is fully charged.
  • You can try a factory reset and start over from scratch. Do this by going to Settings > Backup & Reset > Factory data reset > Reset phone > Erase everything.
  • Your final option is to reach out to OnePlus Support to get your phone repaired or replaced.

Issue: Unable to update

Users on the OnePlus forums have been unable to update their devices using the usual method of downloading the update over Wi-Fi. Attempts to get the new software over Wi-Fi seem to result in failure, or the phone boots into recovery mode.

Potential solutions:

  • This may sound silly, but turn your device completely off, then turn it back on and retry the update.
  • You can install OxygenOS updates manually by downloading it to your Mac/PC and connecting your device to your computer using a USB cable. OnePlus has clear, step-by-step instructions on how to update your device using this method, which you can find on the OnePlus downloads page.

Problem: Device overheating or becomes hot while charging

Quite a few people on the OnePlus forums have complained about that their phones are running hotter than usual, either during everyday use, while in their pocket, or while charging. It was one of the more common issues with the OnePlus 3, and the issue has persisted with the release of the OnePlus 3T.

Potential solutions:

  • Restart your phone and continue using it normally to see if it gets hot again.
  • An app constantly running in the background may be causing the problem. Be sure to close any apps that aren’t needed, or ones you’re not currently using.
  • If the problem started after installing new apps, the new apps may be the cause of the issue. Delete them one by one to see if your phone’s temperature changes during regular use.
  • If your device gets hot while charging, the easiest thing to do is to stop using it while it charges.
  • The OnePlus 3 has a feature known as Dash Charge, which is meant to charge your device quickly but keep the phone cool. However, the feature only works with the Dash Charger Adapter, which costs $20 on the OnePlus website. If you think the charger your device came with is the culprit, consider replacing it, or get the Dash Charge Adapter.
  • The fingerprint sensor has also been said to be the culprit, especially when your smartphone is placed within a pocket. The sensor continues to search for a fingerprint while in the pocket, assuming the screen is facing your leg. A quick solution is to turn the phone around before popping it in your pocket. You could also invest in a flip case, which also has been said to eliminate the problem.
  • If none of the aforementioned solutions are an option, you can always disable the fingerprint scanner until a fix is implemented. Hopefully, you don’t rely on it too much.
