Posted yesterday morning to the company’s forum, OnePlus is detailing what caused the 911 reboot bug that had many OnePlus 5 owners worried. As a reminder, this bug has since been fixed via an update that went out last week.

According to OnePlus, this issue was related to a modem memory usage issue that triggered the reboots. As stated, it was only an occurrence for some users on a VoLTE network where OTDOA protocol was triggered. OnePlus worked with Qualcomm to resolve the issue globally.

Here’s the complete rundown provided by OnePlus on its forum.

Last week, we received distressing news regarding an issue related to dialing an emergency number on the OnePlus 5. Late last week an update was released to resolve the issue. We would like to provide additional information on the emergency call issue.

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.

We have worked with our partners at Qualcomm to resolve this issue globally.

To clarify, this occurred only on some OnePlus 5 devices, in random instances under the circumstances described above. Starting last Friday, we rolled out a software update that resolved this issue.

We took this extremely seriously and want to thank the users who provided device logs to help us quickly resolve it.

All we can say is, we’re happy the company worked so quickly to fix it.

// OnePlus
