Question about Samsung SCH-u740 Cellular Phone

1 Answer

Blue tooth This is my second samsung SCH-U740 that has stopped working with my blue tooths. I works for a while then I can no longer make or receive calls on either of the two blue tooths I have paired to it. I can hear it ring, push the button and it answers the call but I can't hear or be heard. I have to switch to the actual phone. Any ideas?

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.

Below are two known methods for unlocking your phone.

To unlock a Samsung turn the phone off take the sim card and type the following code *#pw+15853649247w#

Master reset(unlock) #*7337# (for the new samsungs E700 x600 but not E710)

Good luck, hope one of those works for your phone. Not 100% guaranteed to work on all models. Thank you for stopping by Fixya!

I cannot connect two cellphones with blue tooth


As I told someone else, Verizon has put a block on bluetooth capabilities. I have found the only thing the bluetooth is good for is a headset.
