Before you make any changes to your phone (Step 3), you need to understand that…
- You might void any warranty from your mobile operator and OEM. Contact your mobile operator if you’re concerned about any repercussions.
- A preview update only includes the Microsoft portion of the update; mobile operator and OEM driver updates will be available when the official update for your phone is available. This means that operating system updates haven’t gone through all of the detailed testing with regards to your phone’s mobile service and hardware, so you might experience some bugs.
- After you update your phone to a preview version of the operating system, you can’t go back to a previous released version of the operating system. When the new operating system is released to the public, you’ll get the update on your phone, but there’s no going back before then.
