    Whenever I place or recieve a call without using bluetooth my screen goes black. The phone continues to work as in receiving calls/texts/emails but I cannot interact with the keypad or initiate a call over the speaker.

    The phone doesn't have a screen protector. I have the latest firmware: 002.0000.0037.0001, OS Build: 10.015254.12. I have done two hard resets but the problem still persists. Hitting power button doesn't work. I turned off change brightness automatically. It is quite frustrating, thanks for any help.

    The proximity sensor could be broken or blocke. The only time that I've seen that happen is when someone had a sticker over the front camera blocking the sensor.

    I looked in the manual and I don't see a proximity sensor listed anywhere...

    All phones have one, it's what turns off the screen when you put it up to your ear.

    At the top of the phone, you can probably see a cut out for it. I don't have one to look at at. You could test speaker phone, to see if the screen stays on.

    Then it's probably the sensor that's not working because it's not used while on speaker phone. Make sure it's not dirty or covered by a case. You may need to contact HP.

    Thanks. It is a replacement phone. I am thinking it was refurbished but not actually refurbished...
