Secret to Unlocking Jelly Bean Service Modes

Buried in the comments of an androidcentral.com article showing a code to unlock "Service Mode," which allows for the testing of many features on the S3, I found the trick to open the gates of Valhalla! This works on my 4.1.2
The secret is to first type *#22745927 to get to an 'enable/disable hidden menu' screen. Check enable and you're good to go.
The code *#0*# gives this testing screen:

Also, the code *#0011# works to access "Service Menu" and change the Wifi Power Save to off. It is thought that this might solve the Wifi disconnecting problem for some people.
Here's the link where I found it: How to uncover and use the hidden Service menu on the Galaxy S3 | Android Central

Most interesting hacks require root and other tweaks, but here is a simple way of getting info on your device and changing some settings not possible in the normal menus. Simply open the dialer on your phone and enter some numbers!

1. 

   Basic phone info

   In the dialer enter *#*#4636#*#* You will then see a testing page, which gives you info on the phone, as well as battery stats and app usage stats. In the Wifi menu you can get info on the network you are connected to and more.

2. 

   Change the power button action

   Entering  *#*#7594#*#* will bring up the menu to adjust the power button action. Dependent on your ROM you usually see a list of actions such as ‘Reboot – Airplane Mode’ etc, this allows you to remove these.

3. 

   HTC Update checking

   *#*# 2432546#*#* If you use an HTC device, you can force a check for updates using this code. This will bring up a notification telling you whether or not it has been successful. Be careful if you are using a custom ROM , as some updates may not be compatible with it.

Temporarily Block Selected Websites:

Using This Freeware For Blocking Access To Websites:

Download this freeware from the link given at the end of this review. The size of the file is 12.1 MB. It is a portable software and does not require any installation. Just run its executable file and you are done.

You need to start this application by right clicking on it and run as administrator. When you run this software, you will see a simple window, as seen below. In this window, you just need to add the list of websites that you want to block.

After that move the slider and set your desired time. You can choose time between 15 minutes to 24 hours and 45 minutes.

Here I chose 15 minutes for blocking the desired website. Next click on “Start” button. This will bring up a small countdown timer that will show time left for website to be unblocked. Once the time elapses, it will automatically unblock the websites.

How Does SelfRestraint Actually Works:

This software is actually a modified form of a hosts file editor. Whenever you choose to block any website, it makes modification to hosts file of your PC and adds blocked websites to that.

When the time elapses, it just removes those websites from the Hosts file.

Bug in SelfRestraint:

This software has a major flaw, since at least 2 years, that has not been fixed till date. When the timer runs, you have to let it keep running. If you exit the timer, then the websites that you had added to blocked list will remain permanently blocked!

There are a couple of ways to fix this problem:

• Start SelfRestraint software again and add the same list of websites to it. Set the timer for 15 minutes. Once the time elapses, it will unblock all the websites.
• Or, just go to Hosts file of your computer and remove entries for those websites.

Key Features of this software to temporarily block websites:

• Selfrestraint is a freeware.
• Selfrestraint helps you in blocking distracting websites for a short time period.
• Selfrestraint is a cross platform application.
• It does not require any installation.
• Selfrestraint is compatible with Windows XP/Vista/7/8/8.1.

My Opinion About Selfrestraint:

Personally, I don’t find this software useful, as I can easily open Hosts file myself and make the changes. I would rather install some advanced computer time management software to regulate how much time I am spending on different websites.

However, the USP of this software is that it is pretty easy to use. I really wish that the developer fixes the long pending bug. Also, I hope there is an option to close the timer, as timer seems to be a constant reminder that some websites are blocked and it serves more of a distraction.
