A glitch that's been hanging around since iOS 7 was released has caused many users springboards to restart resulting in the black or white Apple logo screen to appear. Now this is finally being fixed in a future iOS 7 update according to a Apple spokesperson speaking to Mashable,
We have a fix in an upcoming software update for a bug that can occasionally cause a home screen crash
I myself have experienced such crashes and while they only happen every so often they can be a real pain if you're doing something important, so it's good to see Apple has finally acknowledge it.
Developers are currently testing iOS 7 beta 4 which the fix doesn't seem to be part of, but we'd except the final release will.
