Just a month ago, OnePlus was caught collecting personally identifiable data from phone owners through incredibly detailed analytics. While the company eventually reversed course on the data collection, another discovery has been made in the software of OnePlus phones. One developer found an application intended for factory testing, and through some investigation and reverse-engineering, was able to obtain root access using it.
People often tout OnePlus phones as an alternative to the Pixel line now that Google abandoned the Nexus concept of affordable, high-quality phones. Recent events, however, have made it very clear that you should really steer clear of phones like this, unless you know very well what you’re doing.
And at the xda-developers news section, they published as “accidentally pre-installed app issue”. Jesus. Some people like to believe that wrong actions done by phone makers are by accident…
Rooting doesn’t make any device insecure. It requires an actual vulnerability in order to be abused.
