No Ear speaker No screen either Side both black

I also thought the Pantech Ease had a front camera but what has been call a front facing camera by some is actually a sensor that detects when you have the phone up to your ear.

The sensor is that small round hole you see under the glass just to the left of the ATT logo and the ear speaker. Try making a phone call to your voice mail. You may not have noticed that the screen goes black when you place the phone next to your ear during a call. (this helps save battery life) During the phone call take the phone away from your ear an in 1 or 2 seconds the screen will come back on with menu options for features you can use during a call.

Now test the sensor by placing your finger tip over the sensor hole. The screen will instantly go blank. Remove your finger and the screen comes back on. Put your finger on the glass to the Right side of the ATT logo and the screen will stay on because that hole on the Left side is the sensor.

Like I said before, some sources describe that sensor as a camera which is only half true. Unfortunately I was also fooled by this misinformation. I was hoping to have a front facing camera to use with Skype. I was a fool to believe their hype.

you need to change the ear speaker, your ear speaker is dead
place new ear speaker it will solve the problem

I personally own the Jabra Halo, Altec Lansing Backbeat, and the Motorola MotoRokr S9HD
The Jabra Halo is about 50 bucks and goes over the ear with flat speakers.
The Backbeats are about 100, and provide channeling audio via in ear plugs, but not sound isolation.
the Motorola headset is about 100 dollars, but has issues with skipping, especially if the phone is in your back pocket.

The screen on the droid shuts off to conserve battery power. The amount of time that it remains on can be adjusted in the settings menu, under sound and display, screen timeout. The screen can be turned back on after a timeout by pressing the power button on top of the phone momentarily (quickly, dont hold down). Also, the screen will go black when you hold the phone up to your ear, and then light back up when you remove it from your ear. Hope this solves your problem, if not just let me know.

There is a defect with this phone call motorola at 1800-453-0920 and they can fix it or if you are still in your 1 year there is a warrenty and they have to replace it

First take the phone to a mobile service center and have them replaced your ear piece as well as the flexcable to correct these issues.

Just becausae the cable size is the same doesn't mean that the pin-out is the same. The display needs to be the correct one. It is quite possible that the displays are similar, but the pin assignments are different. This can be confirmed if you look at the numbers on the actual displays. You will most likely find that many of the numbers are the same. It is common for "upgraded" products to also contain upgraded parts. In other words, the display has been slightly modified to provide some slight new feature that the old one couldn't handle. This new pin-out forces the use of the new displays.

Have you raised the volume while you are on a call as this is the only way the ear piece volume increases.
If this doesn't work then I'm affraid you have a faulty earpiece

Check the middle button on the side. Hold it in and raise the earpiece volume to the highest before you throw the phone away.

This exact issue happened to me: I left my phone off for 2 days (unplugged), turned it back on and the internal speaker started working normally again. The phone worked normally for over a month after this. Yesterday, the earpiece speaker stopped working again after the phone fell out of my pocket. I suspect a loose connection or something similar, but I've had my phone off for the last day and will let you know whether or not it starts working again.
