Earlier this week, it was revealed that independent phone maker OnePlus was collecting all manner of information from phones running its OxygenOS — without telling users, of course. Caught red-handed, the company is backing off from the opt-out data collection program, giving users a choice up front instead of buried in the options.

The offending telemetry was discovered earlier this week, when software engineer Christopher Moore happened to snoop on his phone’s traffic for a hacking challenge. He noticed that the device was phoning home to OnePlus when it crashed — which is expected and benign — but also every time the phone was woken up or put to sleep — which is odd and intrusive.
