Two days ago I bought a brand new LG Connect from a Metro PCS store. Sometimes, when I call someone or get a call the screen will automatically turn off even if I am not near it. It refuses to turn back on until the call has ended. The other half of the time, the screen wont turn back on at all so I have to hold the power button and have it go through the whole boot up process. I can still hear and people can hear me, but I am unable to access my phone to, for example, end the call, put it on speaker, etc. This doesnt always happen, but when it does, it will occur for the next many calls and then my phone will be fine. Please help! I cant figure out what the problem is. If I cant fix it I will just have to take it in and get a new one or something... Thank you!
