It's in the phone settings. You will need the 4-digit security code to complete the process. Default is either "0000" or the last 4 digits of your phone number.

Possible the earpiece has gone bad. Can you test with another earpiece?
Remove battery and examine metal contact points for dirt. Can clean with a pencil eraser.

Can not hear callers and caller can not hear me I hear ring tone I can txt my alarm works just no phone calls


Hi, You will need to replace the earpiece and the mouthpiece.

The earpiece makes you to hear callers when they call, and the mouthpiece allows the callers to hear you when you call.

When you replace the mouthpiece and earpiece,the phone will be normal again.

Take care.

Hello,

This is not a setting problem, the problem is that the earpiece of your phone is bad that is why you cannot hear callers voice.

The speaker you put it is for the ringer, it does not have anything to do with earpiece and you can hear your caller through it.

To fix the earpiece problem, you will need to replace the earpiece on your phone in other for you to hear your caller. just change the earpiece as advice and you will see that the problem is solve.

My earphone speaker doesnt work - only the speakerphone works on my SCH-U740. there is no icon indicating the speaker is on/off so pressing the right side button is of no use.


There must be a solution to this very common problem, WHAT IS IT???
Please help me, I just want to know where to take it for repair or directions how I can do it myself and where can I find replacement parts. Come on, maybe Samsung should recall the SCH-U740 and take on the costly $amount$. After purchasing the SCH-u740 Cellular Phone consumers should not have to pay for expert advice, thats what customer service and satisfaction is all about.

My samsung SCH-U740 will not power up, just sits and vibrates.


I think your only options are to have the phone refurbished or replaced. The SCH-U740 is extremely sensitive to moisture.

U740 inside LCD cracked - need replacement directions


James121 is not correct. In this case, with the Samsun sch-u740, the screws are simple small philips screws. Its also pretty tough to get the cover off. you also have to deal with alot of wires to replace the lcd, including soldering the speaker back to the lcd. this is not recommended for 99% of people.
