I recently shattered the screen to my Google Nexus 4 phone. Not just cracked, shattered - tons of spider web lines. I looked up YouTube videos of how to replace the screen and almost ordered a replacement repair kit but then wondered if it's just the screen that's broken or if it damaged the phone, too. Is there any way to tell/test it? The screen does not respond to my touch but still turns on and the color and brightness look fine. I guess I don't want to spend $100 replacing the screen only to find that the phone is broken and I really just need to buy a whole new phone. Anyone know if I can test if just my screen is broken vs. the phone itself?
