My Samsung Galaxy 3 (GT-i5801) is not being detected by my PC -- What should I do? I have a Samsung Galaxy 3 (GT-i5801) Android phone. Currently, my phone is not being detected by my PC. Initially, when I purchased this phone, I was developing applications and I was able to run the applications on my phone. I have purchased a new cable as I thought the data cable may have been damaged, but that did not solve the issue.

What can be the possible solutions or what do I need to check for in order to connect my Samsung Galaxy 3 to my PC by using a data/USB cable?

I have Windows XP installed on my Dell Inspiron laptop.
After searching for a long time and trying a lot, I found a solution:

Resolution


Unplug the USB cable
On the cell phone, dial the number *#7284#.
Once the last # is hit, the PhoneUtil application is launched. Choose USB -> Modem and then USB -> PDA mode. The good mode should be PDA. Even if the mode is PDA, switch to Modem and then back to PDA.


Also choose UART -> PDA and then UART -> MODEM mode. The good mode should be MODEM for UART. Even if the mode is MODEM, switch to PDA and then back to MODEM(UART).

Plug in the USB cable.


Note:

This is not only for Samsung Galaxy 3 - Android phone, but it is also used to repair the USB connection for any Samsung Android phone.
