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

Samsung SCH-u740 problem - front screen stays on and speakerphone switches automatically

I would recommend a hard-reset of the device. Keep in mind that this will delete all of your contact information and customized settings.

On a side note, be careful not to accidentally press the speaker-phone button on the right side of the phone during a call. I used to have this phone and I would sometimes do it without even realizing it.

Silent mode (vibrate only) capability

Although there is no real profile support in the SCH-u740, a simple downward press on the volume rocker lets you quickly silence the phone, while pressing upwards will reactivate the normal ringer.
With the phone open, a long press on the 'T' or '#' key will toggle the VIBRATION mode. The device comes with 11 ringtones built-in, but they are very basic sounding.
