iOS 7 is not playing nice with my 4S

[BenFromPerth23]

Since installing iOS7, I've noticed some weird behaviour on my 4s.

1. One of my contacts (a favorite) was deleted, then reappeared. I could see her number, but no other details. Then it all came back.
2. I keep getting signed out of iCloud. Signing back in is hit and miss, and it keeps telling me my password is wrong.
3. Speakerphone seems to have a mind of it's own.

Anyone experienced any of this?

Anyone got fixes?

Also, regarding animations, they're slow. Any way to turn them off/speed them up?

Cheers!

Did you try setting up your phone as new under iOS7 and then re-configuring iCloud? This may fix some of the issues you're having.

Yes, try a restore/setup-as-new.

iOS7 was quite solid on my 4S with none of the issues you describe.

It could be more of an issue with the phone rather thank iOS7. I have 4 iPhone 4S's with iOS7 and not a single glitch. I think I'd wipe that phone clean and start from a NEW install.
