Buggy open beta software pulled by OnePlus for several models
The open beta updates recalled by OnePlus include Open Beta 5 for the OnePlus 5T, Open Beta 7 for the OnePlus 5,Open Beta 24 for the OnePlus 3T, and Open Beta 33 for the OnePlus 3. OnePlus does caution those interested in trying out these builds that "This is beta software. These builds are sometimes not as stable as our official OTAs generally are. By installing this update, you accept the potential risks."
According to posts on the OnePlus user forum, the open beta updates had a very negative effect on battery life. One user said that after installing the software, his phone was warm to the touch even with the screen off, and for two straight nights the battery percentage dropped 20 percentage points overnight.
There is no word on when these open beta updates will be fixed, and offered once again to OnePlus users.
