While there are rumors of a new OnePlus handset on the horizon, the firm has fortunately not forgotten about its current models, the OnePlus 3 and 3T. Those that are looking to have the latest in terms of software will be happy to know that the firm does have an open beta available that will update both models to Android 8.0 Oreo.
Unfortunately, this isn"t as simple as just clicking an update button on your phone and will require a computer, along with a user who can follow instructions carefully. Before starting the procedure, just to be cautious, you will want to back up any important information that is on your device. Once that is complete, you should make sure that your device is using the stock OxygenOS with Oxygen Recovery.
By heading to the proper source link below for your model, you will be able to download the appropriate OS for your device. You"ll also need to boot into recovery mode, enable it to load from USB, and then proceed to plug in the device to a computer. If all goes well, your phone should reboot with Android 8.0 Oreo. Since this is a beta, there are known issues, which can be seen in detail below.
- Fingerprint unlock may be a bit slow in some situations
- Shortcut to access Google Photos is unavailable
- Stability of NFC and Bluetooth need to be improved
- Performance and compatibility of 3rd party apps will be optimized continuously
- Complete device tree will be released after a week
Again, this is a complicated procedure that could result in data loss: follow the instructions properly. Neowin is not responsible in any way with complications that might arise. Otherwise, good luck!
