SE C905 Down Key malfunction

Hello,

I have a c905 and i had recently updated my software, however now i notice that when ever i press the down key instead of scrolling down, it comes to the home screen and if i hold i long enough it shuts down the fun...so basically it acts as the END key now, this seems like a glitch in the software, any suggestions on how can i resolve this issue?

Thanks

i do know plp are haveing problems with there key pads on c905 try to reflash /update again see iff this resloves it if not time to get a replacement;)
