Android's security update for January is coming next week?1
After the Pixel and Pixel XL receive the security update, it will probably be pushed out to other Android handsets during January. As we told you earlier today, also expected to get pushed out in January is Android 7.1.1 for the Nexus 6. While all of the other eligible Nexus models had no problem with the update, that wasn't the case with the Motorola built 6-incher. So Google will try again to get the latest version of Android installed on the phablet next month.
When you receive the notification on your Android phone that the security update has arrived, make sure that you are connected to a Wi-Fi signal and that your battery is fully charged before starting the updating process. This way, updating the phone won't cost you any of your valuable data, and you won't have to worry about the battery shutting down in the middle of updating the handset. If that were to happen, there could be a problem finishing up the updating process. Making matters worse, in the worse case scenario, your phone could get bricked. That is why it is suggested that you power up your cell before starting the update.
