While playing slant on my newly 51-3 updated N800 I've seen a few "phantom screen touches" - i.e. the game has reacted as if I have touched a different part of the screen to where my stylus actually is. I've also had one or two occasions when a different app (picture viewer or browser) has jumped to foreground unexpectedly. Whether this is a side-effect of 51-3 or a coincidental hardware problem I cannot say. Has anyone else seen this happening?
