Low wifi + no sound during call?

Hi,

A year ago I dropped my iPhone 4 (my screen got totally broken and nothing showed on but when I put it in charger the phone vibrates) so now I bought another iPhone 4 with a broken motherboard and replaced the broken motherboard with mine. The phone started normally ;I backuped my data and restored it and after that I noticed that the wifi range is very low I have to be near the router to access to wifi and when I put sim card it detects it and shows me the signal and the carrier but when I call or get a phone call I can't hear the other side ,neither can he. I tried earphones with microphones but without success I noticed that if I dial a number in the keypad (http://i.i.cbsi.com/cnwk.1d/i/tim/2011/0...) during a call the other side hears the sound of the numbers and the 3G works without any problem I'm on IOS 7.1.2.

Thanks.

Check if you have the latest update installed.

Try to change date/time settings from Auto to Manual... restart the phone... and change back again. Also, check if you are logged in right Region. Sounds weird but this setting causes all kind of troubles all the time.

Hard reset (Power and Home button together till Apple sign appears)
