Firmware upgrade? Is it really needed?

[ZeJudge]

Ive bought 2 ipod nano clones now, both identicle and both have firmware version 9.1.25 or something like that. They seem ok but the buttons do the wrong actions and was wondering if upgrading the firmware would fix it?

And just curious, what does updated firmware actually do or change? Are there new features?

Any opinions on this?

Thanks,
Jon
