Highlights

    • Some OnePlus 5 users faced reboot issue each time they called 911 emergency
    • OnePlus said the fix occurred when a user used VoLTE to call emergency numbers
    • OnePlus addressed the issue by a recent software update

Amidst several issues that occurred on the OnePlus 5, some users owning this flagship faced a serious one that caused devices to reboot while trying to place a 911 emergency call. OnePlus, however, acknowledged the issue and quickly pushed a software update to fix the problem.

While this was a grave issue, users reasonably wanted to know why the reboot occurred in the first place. And OnePlus did explain the reason behind this dangerous bug in its official forum.

According to OnePlus, there was a “modem memory usage” problem that cropped up when a user used VoLTE (voice over LTE) to call emergency numbers on the OnePlus 5. The call invoked an OTDOA (Observed Time Difference of Arrival) protocol transmitting the user’s location to emergency operators. OnePlus said that it worked with Qualcomm to eliminate the issue globally on OnePlus 5 (Review) devices.

Here is what OnePlus had to say about the problem:

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 for helping us quickly resolve it.”

Notably, the reboot issue on the OnePlus 5 was reported last week, when some users tried to make emergency calls to 911, and they couldn’t do so due to the bug. According to users, every time they tried to place the emergency call the device rebooted. It’s good to see OnePlus being quick enough to address the issue thanks to the fix that was available on last Friday.
