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.

    there is no need for the exclamation marks, imo.

    Can you tell us what was the message or any other information?

    @Louis Rhys usb device not recognized message is being coming up when i try to connect !! I think i am trying to connect with USB cable so no need to install driver

    I have similar problem with Samsung Galaxy 3, i5801. Initially mount dialog was appearing but now it is not. it just charge mobile. Do that dialog requires any specific service or program, which might have be uninstalled accidently? In settings-about phone-usb settings- mass storage option is enabled, also tried with ask on connection but no luck. What could be the problem? Thanks in advance.

  • After searching for a long time and trying a lot, I found a solution:

    Resolution

    1. Unplug the USB cable
    2. 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.

      1. 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).
    3. 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.

    A thousand Thanks to Paresh Mayani for the *#7284# tip. USB connection stopped working on my new Galaxy 3 and all Samsung Customer Support suggested was to do a factory reset. I expect that would have solved the problem, but at the expense of losing all my personal settings. So thumbs up for Paresh and thumbs down for Samsung Customer Support!

    @Michael Thanx for the kind words, i was in same situation as you are, later on i found this solution so i shared it here. Samsung Customer Support had told me for the Factory Reset, what a majak they had done!! They should have atleast know about this *#7284#

    I am having same problem again but this time this solution doesnt work ... any other idea ???

    @PareshMayani I have a galaxy s3 and installed paranoid android 4.5 ( kitkat 4.4.4 ), but *#7284# does not show anything!
