Problems? That sucks! Sorry to hear. If your Samsung I5510 needs a little TLC, you have a couple options. You could contact the store where you originally purchased the device or you could contact Samsung directly. Your eligibility for repair, replacement or support may depend on the warranty period remaining. Good luck!
I hear the notification ring that a message has come, but the message is not visible on the phone. I have missed 3 very important messages today.
