i recently upgraded my os to 4.5 and now everything is a little screwed. my camera takes twice as long to load and my tones for ssm and mms play the sound like 10 seconds after i receive the msg... ive already done a battery pull and no luck... is this normal?

Did you update to the latest version of 4.5?

How much File Free do you have? Options -> Status.

Can you revert to your backup?

Nope. Which one did you upgrade to? There are countless builds of 4.5 for the 8310.

Once you answer some of teh questions above, we may be able to help. To echo dubdub, we are hoping you did a backup

13 MB is ok, ideally you want more.. Do you how much further it goes down?

If it runs too long that will slow down your BB a great deal.

what do you mean if it runs too long it will slow down......?

Ment if your memory keeps dropping it will slow down even more.

Make sure you close any running apps you don't need running, instead of using the Back button.
