Nokia (NYSE: NOK) has released a new firmware upgrade for its N78 smartphone. The update fixes a number of bugs and glitches found in the previous firmware v20.149. The detailed change log is not available at the moment, but as always we advise you to keep your devices up to date (and to backup your data prior to doing so).
To grab the latest firmware, you can either use Nokia Software Updater desktop software or do everything from the phone itself. In the latter case, go to “Tools” > “Utilities” > “Device Manager.” Once there, select “Options,” “Check for updates,” and then follow the instructions provided on the screen. If you opt to update your N78 over the air, make sure you’re using a WiFi connection to save some bandwidth costs — that’s in case if you’re not on an unlimited data plan. The file is smaller than 1 MB, so it shouldn’t take long to download it. Good luck!
