Has anyone had the following glitches happen to them?

when i'm scrolling through my album art for my music... the album art goes away after scrolling for a minute or so ... and i usually put my phone right side up and then i put my phone sideways again to get my album art again.

AND

if listening to music it sometimes just stops the music and goes back to my springboard....


AND

if i'm scrolling up and down through my text messages it will just go back to my springboard

AND

if listening to music though the speaker ... it gets distorded ...

the only way to fix these glitches is turning the iphone off and on ...

its not that big a deal because it doesn't happen all the often. but if it didn't happen at all that'd be even better!
