Motorola releases update to fix the issue causing one-way audio following emergency diallingReuters

Motorola is rolling out a software update 'Emergency Dialing Maintenance Release' for a wave of Moto devices and the sixth generation Nexus smartphone.

Installing the update when it is available, will fix the issue that causes one-way audio following emergency dialling. Expect the update on the following devices.

  • Moto X (1st Gen)
  • Moto X (2nd Gen)
  • Nexus 6
  • Droid Turbo
  • Moto Maxx / Turbo
  • Droid Ultra
  • Moto X Pro

Motorola further confirms that those using pre-PIN and pre-pattern emergency dial option on the screen lock are not affected. Most of the users usually do not power off their devices regularly and a very few use encryption and PIN-to-start.

The issue arises only in certain rare situations such as the following:

  • The user has encrypted the phone with "PIN to start" enabled (note that this is the PIN entered on an encrypted phone when it is powered on and boots up, not the PIN or pattern often entered to bypass the screen lock on a phone that is already powered on).
  • The phone is fully powered off and then the user powers it on (not just wakes it) to place an emergency call.
  • Upon boot-up, the user selects the emergency dial shortcut option that is presented before the boot PIN is entered, rather than allowing the phone to boot completely before placing the emergency call.

In these aforementioned cases, the call will be connected, but there will only be one-way audio. The user will be able to hear the dispatcher, but the dispatcher will fail to do so.

Users awaiting the update can perform the following to ensure that outgoing audio in emergency calls is not affected.

  • Keep your phone powered on. Once the phone is fully powered on, this situation will not arise.
  • If you must power on your phone to place an emergency call and do have PIN-to-start enabled, enter the start PIN and allow the phone to boot completely before placing the call.
