Version 1.67 said to make things stable
The PlayStation Vita will get another firmware update that has just been released. Coming in at 97MB, the latest firmware is said to address a number of stability issues and make the system more stable with a number of PlayStation Vita titles.
The version 1.67 update comes hot on the heels of a mandatory update that just dropped about a week ago. The last update seems to have caused issues for some users and created stability problems, while other users claimed to have no issues. It does seem to be related to the particular games you are playing.
If you own a PlayStation Vita, then you might as well update it, as we doubt that it could make things much worse than they already are for those having stability issues.
