Smart Mobile Phone SOME IMPORTANT SOLUTION

Some Useful and Interesting Codes for Smartphones

This page contains a list of codes that can be entered into most Smartphones to retrieve important information run diagnostics and test the functionality of the device.
The codes below are primarily for Smartphones running on the Android Operating System but some codes listed will also work on basic phones and Smartphones that might not be built on the Android OS such as iPhones (iOS), Windows Phones, Nokia Phones (Symbian), etc. Some codes only work for specific manufacturers, some for specific versions of the operating system, some makes and models of phones just don’t like to work at all.
Disclaimer: This page is for educational and informative purposes only, and a few of these codes I wouldn’t recommend a basic or novice phone user to perform. Some of these codes can clear important information from your device if not already saved properly. So all in all, read the description of what the code is intended to do and perform these codes at your own risk because I will not be held responsible or accountable. Otherwise enjoy the codes and enjoy the article.
To input these codes on your phone all you have to do is open up your dialer as though you’re dialing a telephone number and then enter the code. After typing in the code the phone should pull up whatever option you’re testing. Some of these codes you might need to enter the code and then call/dial it.
*#*#4636#*#* or *#*#INFO#*#* can be used to check a lot of things on most Android Smartphones. Including:
Phone information -allows you to run a ping test, and shows a ton of interesting information about the phone.
Battery Information – now you can remove that power app you installed on your phone, all the common information you need about your battery and charging is here.
  • Battery Status: Shows whether the device is charging or if the battery is full.
  • Power Plug: Shows how the device is charging, AC (wall charger), USB (computer) etc.
  • Battery level: at what Percent the battery is charged.
  • Battery scale: should read “100”.
  • Battery Health: should say “Good”. If it shows “unknown” or “unknown error” then you should power cycle (turn the phone off than on) and check again. If it still doesn’t say good. Then the battery itself is likely defective.
  • Battery Voltage: really isn’t something the average phone user is going to need to worry about.
  • Battery Temperature: if your phones getting HOT you can check and see if it’s your battery that’s heating up or the phone itself.
  • Battery technology: usually just shows Li ion (because of the common Lithium Ion batteries found in the majority of these devices).
  • Time since boot: shows the amount of time since you last booted up or turned on the phone.

*#7353# will access the Device Diagnostic Tool on Samsung phones and some other Smartphones excluding the HTC.
*#*#3424#*#* is how to open the Device Diagnostic Tool on an HTC Android phone.
*#06# shows the IMEI number of your phone. The IMEI is a unique 15 digit number for your specific phone, basically the Social Security number of your phone. Sometimes when typing in *#06# it will add an additional 2 digits at the end. The first 15 digits shown before any space or dash is your IMEI.
*2767*3855# is a code to perform a VERY THOROUGH complete wipe on a Samsung phone. Never type in this code until you backup your entire phone, it will not erase your Operating System or preinstalled applications. It will erase all personal data and settings. If you have tried to perform a Factory Data Reset on your Smartphone and it didn’t solve your issue then this code might be exactly what you’re looking for. PS also remove your SD card or Memory card from the phone before using this code.

*#*#7780#*#* is an alternate code to perform a Factory Data reset on some Android Smartphones. Don’t do this unless you’ve backed up your phone so you don’t lose anything. Once you type in this code the phone will show the option to erase the memory on the device and provide the option to format the SD card as well. Note: In order to finish the reset you will have to tap the “Reset phone” button shown on the screen.
*#7380# is a soft reset code to restore the phones original factory default settings (just settings not a full clear) on Nokia mobile phones.
*#7370# is a hard reset on Nokia phones, this restores the whole phone, not just the settings, so make sure you do a backup first, if possible.
*#*#34971539#*#* this code can be used to get information about your phone’s camera. It shows following:
Update camera firmware in image (Don't try this option because it will most likely break your phone)
Get firmware update count
Get camera firmware version
Update camera firmware in SD card
*#1234# displays software/firmware information.
*#*#7594#*#* this code can be used to change the "End Call/Power" option on your phone. So instead of having to select the Silent mode, Air Plane mode or Power off, you can just use the power key to power the phone right off.
*#*#232339#*#* or *#*#526#*#* or *#*#528#*#* - Wireless LAN (WLAN) test. Just use the phones "Menu" button to start the various tests).

*#*#2222#*#* shows the FTA HW Version.
*#*#1111#*#* shows the FTA SW Version.
##21# will cancel your phones registration from your service provider and should allow you to connect to the closest tower in your area. Once you type in the code you will have to actually call it, it will show a message and then go through… try and make a call or two and see if the service has improved. If yes enjoy, if not then power cycle your phone (turn it off and then back on). I don’t usually recommend this code be used unless you’re having pretty constant network related issues. If for some reason you have minimal service after entering this code and you have tried restarting your phone then you might have to contact your wireless provider to get them to reconnect you to the network (which power cycling should do for you), just call in and let them know that you suddenly had no service, should be one of the standard things they check for service related issues, just have them send an OTA (Over The Air Activation) to your phone (so far only confirmed on AT&T phones).
*#*#0283#*#* can check the Packet Loopback for networking.
*#*#0*#*#* - run a LCD test on your screen.
*#*#0673#*#* OR *#*#0289#*#* is how you run a Melody test for checking the sound. I believe this one is for the external speaker (the speaker that plays music on the phone).
*#*#0842#*#* Device test (vibration test and back light test).
*#*#2664#*#* Touch Screen test for if you think you might have dead spots or areas that don’t respond on the screen.
*#*#2663#*#* to show the Touch Screen version.
*#*#0588#*#* is a Proximity Sensor Test. The proximity sensor is a small little sensor, usually on the top of the phone next the logo or speaker you hold up to your ear, and its purpose is to know when you put your phone to your ear, so that the phone will lock, and you won’t accidently press keys when talking to other people. It then is supposed to realize when you’re removing your phone from your ear so that it can show the display again. If your phone is remaining on a black screen and you’re having issues ending calls then it could be your proximity sensor.
*3001#12345#* opens a Field Test on iPhones. You’ll have to press dial/call for this code to go through. This code opens a lot of different options to go through and see how well or efficiently your iPhone is working. One such future shown includes your phones signal. After typing this code into the phone the signal bars actually turn into a number. The lower the number the worse your signal strength is. Remember the number is a negative so -90 is a worse signal strength on your phone than a -80. Using this code can access a ton of technical information on an iphone, once done going through what you want then just press your home key to exit the Field Test.
*777# then call/dial, should open the account balance on a prepaid iPhone.
*#61# can be used to check the number for unanswered calls on iPhone. Use the code *#62# if you don’t have any service currently available. *#67# if the iPhone is busy.
*#21# provides information on call forwarding options.
*#119# or #*119# is supposed to help take a phone out of Emergency Mode. (submitted by a Sprint employee)
*#30# should show whether the phone has the setting to display its caller ID field enabled or disabled (I have yet to confirm this code. I think it is primarily for iPhones). *#76# is a similar code.
*#33# can be used to check for call control bars on an iPhone.
*#43# shows whether call waiting is enabled or disabled on iPhone.
