If you are a Hot 4 X557 user, you should get the update notification via OTA. The new software update is available via OTA (Over The Air), and it weighs in at around 1.5GB in size. You probably need to connect to a fast Wi-Fi network or subscribe for at least a 2GB data plan for the download, make sure your phone is not rooted and also charge your battery to at least 80% before proceeding with the software update.

Once the above requirements are met, go ahead with the below procedures.
Go to your phone "settings"
Scroll down to "about phone"
Click on it and tap "system update"
You should see the new update, then select the update and install.
Relax and wait for the new update to fully install. After successful installation, your phone will be rebooted and Android 7.0 Nougat will smile to you on the device! Take note that the first booting process might take a few minutes to complete.
