Recently, I am a little bored because of coronavirus, so I reconsidered my old Lumia 800 and found someting new!
As we know, Microsoft stopped supporting ZUNE in 2015. We can not download music and video from ZUNE.com scice then, and this WindowsPhone is unable to upgrade to Windows 10.
But we can also use ZUNE to transport mp3 and mp4 files from PC to Lumia 800, just like iTunes and iPhone.
It is really useful and fast, which makes watching videos and listening to music possible!
Here is the download link for ZUNE software.
You can also download here or here if the first is too slow : )
