To update Sony Xperia Z5, you can take either the official route or the non-official route. The official method to upgrade this device is to use OTA but the problem is that it doesn’t work for everyone. So we’ve included a non-official method towards the end for all those who can’t make the OTA work for some reason.

Update Sony Xperia Z5 using OTA [Official method]

The official method is to use OTA to upgrade your phone. However, there are some problems with OTA.

  1. You can’t get an update through OTA unless your phone manufacturer has worked on the new version of Android. This means you are always dependent on your phone manufacturer.
  2. You can’t get an update on day one. Google Nexus devices are the first one to receive an update.
  3. Your device should be running official version of OS to use OTA.
  4. Your device should not be rooted to benefit from OTA updates.

But if you are eager to try OTA for your Sony phone despite these issues, you can follow the simple procedure explained below.

  • Go to ‘About Phone’ from Settings on your phone.
  • Go to Software Version from the next screen.
  • Search for new updates. If there is an update available in your region, your phone will detect it and prompt you to proceed with the update.
