I have a Samsung Galaxy S3. Are there any codes to enable field test mode, like band selection? Has someone managed to enable such an option?

*#*#7262626#*#* – Perform a field test
*#2263# - If previous doesn't work.

Sadly, Samsung used to provide field test display by entering codes in keypad. However, from Galaxy S3 onward, the service mode *#*#197328640#*#* was disabled. Only *#0011# is still available. The worst is that even the Android default testing info *#*#4636#*#* was disabled as well.

  • Thanks very much for the reply!!!But unfortunately am not able to enable the most important for my case Field Test: ##7262626##.Do you know any way to work it out? – Rizias Sep 17 '14 at 11:31
  • @GiwrgosRizeakos they took a lot of this out in newer firmwares, try *#2263# and let me know. We'll find it! – RossC Sep 17 '14 at 12:02
  • Just managed to do something by rolling back to older software version,but is not excellent....Have you managed to use it properly? – Rizias Sep 17 '14 at 13:23
  • @GiwrgosRizeakos nope, not on any device I have to hand, but they are all newer devices. Annoying. – RossC Sep 17 '14 at 13:52
  • Just a heads-up: most of the asterisks here are disappearing due to Markdown formatting. If you see italic, then it means it's enclosed by single asterisk. If it's bold, then it's enclosed by double asterisk. See the source to see the correct codes. – Andrew T. Dec 9 '14 at 9:28
