I did a couple of tweaks nothing to major just the speed, battery, got rid of the message notification and thats it but now when I use the slide key board sometimes it doesn't work and when it does its slow and puts extra letters ie. hello what you been up to? will come out like hello wwwwwwhat you bbeeeennn upto? and then my phone stopped ringing periodically some times it rings other times it doesn't usually I will just pull the battery out and it fixs it temporarily any ideas are helpful I was thinking virus? idk.
