For $99, the Vivo XL is a great phone. It has a few quirks like dialogs that read "Cancel/Determine" instead of "Cancel/OK", but they aren't a big deal. The one minor issue I have is with the screen lock under Security Settings. The timeout for auto locking can be set If you choose slide to unlock, but if you choose a password, pin, or pattern the timeout is greyed out. Basically if you choose a password your only option is to have the phone lock immediately. Has anyone seen otherwise? I tried setting the timeout while it was on the slide to unlock, then switching it to pattern, but it just goes back to immediately locking.
