You can now load Android 14 beta on your Nothing Phone 1. Here's how to do it.

Nothing Phone 1 runs a relatively lightweight, skinned version of Android called Nothing OS. Since the release of the Nothing Phone 1, the company has done a great job keeping things up to date and has issued a number of improvements as well. Now, the company has made its Android 14 beta available for its handset as part of its Developer Preview Program, giving users an early look at the experience.

How to upgrade to the Android 14 Developer Preview on Nothing Phone 1
You can begin the process by getting your phone ready for the Android 14 update. You'll need to follow the steps in order to get the local update tool to pop up. First, be sure to backup your phone's data. Once you're done, you can hop in.
- Be sure that your phone is on the latest Nothing OS with version 1.5.4.
- If the phone is up-to-date, create a folder in internal storage called ota.
- Download the Android 14 Beta update package
- Move the Android 14 Beta update package to the ota folder.

- Now, open your phone's dialer and enter code #*#682#*#*. This will open the local update tool.
Source: Nothing
- The local update tool will automatically be set to scan the ota folder for an update.
- If it doesn't come up, just refresh by tapping the reload button.
- If you do not have the correct file, there will be an error message.
- Once set, tap the Directly apply OTA from selection button to begin the update process.
- Keep the phone on and on the local updater screen.
Source: Nothing
- When complete, you will see a message that states "Update OTA Success." This will confirm proper installation.
- After you reboot, you should boot into Android 14.
Revert to Android 13
Even if you load into Android 14, you can still revert to Android 13. Of course, you will lose information stored on the phone, so be sure to back up your data before you proceed. If you want to revert, just follow the steps above, and instead of the Android 14 package, just load in the roll-back package. Follow the same process and if all goes well, you should restart back into Android 13. As stated before, Android 14 isn't perfect yet, so there are going to be issues. But if this isn't your primary device, and you want to give it a go, you're always welcome to do so. If you need help, be sure to check out our Nothing Phone 1 XDA Forums.
