For those who value transparency in a company, you’ll be pleased to learn that OnePlus has since come forward with an explanation of the problem (via XDA). According to a post on the OnePlus forums, “The source of this issue was related to a modem memory usage issue that triggered a reboot. This reboot was a random occurrence for some users on VoLTE network where OTDOA protocol was triggered when placing an emergency call.”
The company adds, “We have worked with our partners at Qualcomm to resolve this issue globally.” The problem appears to have been solved for the OnePlus 5, but as the post on XDA points out, there is a thread on Reddit which suggests that this problem could be more widespread than previously thought as there are reports from other users of different devices who are experiencing similar problems.
We’re not sure if the other OEMs involved have managed to address the problem, but hopefully they have or they are working on a fix as we speak.
