The OnePlus 8-series went on sale on 14th April 2020, and shipped with OxygenOS 11 out of the box. It received OxygenOS 12 stable on 22nd March 2022, after a beta period of 1 month. OnePlus has announced an OxygenOS 13 Closed Beta program for the 8 & 8 Pro. Similar to other devices' CB programs (10 Pro, 9 & 9 Pro, 9RT), it will be focused solely on the OxygenOS 13 update and thus should last for 2-3 months. Also, it is open only to users located in India. You should not expect any build in this program to be stable or polished. If you're accepted, your role will consist in finding and reporting OS bugs to OnePlus so that any critical issues will be fixed ahead of public release.
Up to 200 users will be accepted into the closed beta program, but they will have to meet a few requirements:
- own an Indian OnePlus 8 or OnePlus 8 Pro
- be comfortable with taking backups and restoring them (some CB builds may require a "clean flash", resulting in data loss)
- be willing to constantly communicate and provide feedback to OnePlus staff on Telegram
- be an active OnePlus Community member
Besides these requirements, OnePlus may also filter applications based on your other parameters in the survey (e.g. how many times you use your phone per day or your current occupation). Users providing exceptional feedback may be eligible to some gifts.
Joining this crew will require you to sign an NDA (Non-Disclosure Agreement) with OnePlus, meaning you will NOT be allowed to share builds and any content related to it with anyone.
Note: These closed beta builds can be unstable, and we don't recommend applying if you're not experienced in beta testing, or if you're not aware on rollback/downgrade procedures. If you're accepted, OnePlus will provide guides anyway, but we recommend familiarizing yourself with the process beforehand.
