  1. Great info and all codes provided work well on Samsung galaxy s 4.

    Thank you.


  2. Last three codes didn't work for me. Service mode is *#0011# on my phone. I'm still looking for factory reset.

  3. Can’t pass service mode initial image, when chose back then key input and 1 it stays on the same menu :(

  4. Mine too. Cant get further menu on service code.

  5. Just to add some points:

    *#0*# - Testing mode
    *#06# - Show the IMEI number of your phone
    *2767*4387264636# - show the product code
    *#0011# - Service Menu
    *#0228# - Battery status (ADC, RSSI reading)
    # 7353 # - Quick test menu)

  6. *#32489# doesnt not work on t-mobile version (sgh-m919) instead its *#27663368378#

  7. i guess the phone needs to be rooted to use these codes...none work on my just trys to dial

    1. No Joseph its not important that your phone should be rooted. These codes are working fine on non rooted phone

  8. I am getting nowhere with this issue after typing in *#0*# nothing happens

    1. Hello terry *#0*# is the most basic code for all samsung mobiles and it works on samsung galaxy s4 just make sure you are typing it correctly

  9. No codes work on my Galaxy S4, nothing. And, no, I'm not typing *#0*# wrong.
