This is the category page for both the OnePlus 3, and the OnePlus 3T. These OnePlus 3 tips and tutorials were originally written for the OnePlus 3. Since then, the company decided to release a new variant and thankfully most of these guides will work on the OnePlus 3T as well.
There are a few differences though, at least as of right now, so make sure that the guide mentions it will work on both versions of the OnePlus 3. If you’re brand new to modding Android, be sure to check out the OnePlus 3 Customization Starter Guide to learn what order certain things (like rooting) needs to be done in.
