My Samsung Infuse has started doing something weird with no discernable cause (no consistent prior app used before it happens). Out of nowhwere at least once a day for the past few days virtually all text including icon and navigation labels and conrimation messages dissapear. The only way to get them to come back is to shut off and reboot (and even then I have to kind of guess at which box to hit to confirm shut off, as the labels are missing. Any suggestions as to cause or cure? I have not installed anything new immediately prior to this beginning to happen.
