Android tablets featuring Nougat 7.0 have been on the radar for a while now, even in the refurbished tablet market. Below is a guide to help you upgrade an Android tablet running on Marshmallow to Android Nougat 7.0 wirelessly. Note that techies call the wireless Android update as the Over the Air (OTA) update.

  • Navigate to Android Settings and scroll down to the About Tablet
  • Tap on the About Tablet option and go to System Updates to check if latest version of Android exists for download.

If your Android tablets were running on Lollipop, then you would have to update the same to Marshmallow so that you can update further. However, if the latest Nougat OTA update is available for your Android device then you can simply download the same wirelessly. Once the update gets downloaded fully, your Android refurbished tablet would install the update automatically and will reboot the device as usual.

It is also advisable to back up the data in your Android tablet including contacts, photos, SMS, application data, as well as other file types in an external storage device or a PC for future use. In addition to keeping a backup of the data, also ensure that the device is on full battery or at least 50 percent battery when you connect to a wireless router to do the OTA update.

If you want to degrade the device from Android Nougat back to Marshmallow, you would have to use SDK tools for that. However, the OTA update would not induce much risk from users’ part unlike the manual methods. Generally, it is not advisable to update a Nexus device from Marshmallow to Nougat through factory image although techies wanting to get hands on Nougat before anyone else might seek that route.

Android Nougat first arrived on Google Nexus devices and subsequently expanded to other brands namely Samsung, HTC, Motorola, LG, and Sony. Connect the Android device to the Personal Computer, scan all Android data, and then save the same to the computer to ensure you don’t lose any data following the Marshmallow to Nougat upgrade. If you lose data after the upgrade, then you would have to download and install a free data recovery software from Google Play Store and that may re-partition Android tablets.
