I noticed my phone was acting weird. I'd slide out the keyboard and the phone would freeze and then start blinking and all of a sudden the screen went off. ! I figured out that when I'd slide it back in, I'd be able to text and basically use the phone. But once I slide the keyboard out and again the screen acted up. I then tried it again a while later, and my screen completely went off. . I took off the battery, sim card, and put the battery back in. I turned the phone back on, it'd do that vibrate effect that lets you know when the phone is turning on(It always happen either the vibration or a ring sound). The phone vibrated, but the screen was completely black. Its not displaying anymore. Can you guys please help me out. What should I do , and what might be wrong with the phone.

Flex problem obviously
