How to access your Android phone's hidden "Testing" menu

How to access your Android phone's hidden
Most smartphone users rarely discover all the things that their handsets are capable of. But that's OK: as long as a smartphone does what its owner wants it to do, there's no real need for other things. Still, if you have the time and the curiosity to dig deeper into the insides of your phone's software, you may find things that you didn't know were there.

All mobile phones have some secret codes that don't come with the manual, so it's no wonder that such codes work on Android smartphones. We'll now show you a code that reveals a hidden Android Testing menu ("testing" is literally the name of this menu). The code is *#*#4636#*#* - you'll just need to introduce it via your phone's dialer. Once the last character is introduced, the Testing menu appears out of nowhere, showing you four sub-menus: Phone information (IMEI number, current network, etc.), Battery information (including health, voltage, and temperature), Usage statistics (showing the apps that were last used on your smartphone, including the exact usage time), and Wi-Fi information (besides finding Wi-Fi information, and being able to disable or enable networks, you can run ping tests from here - though you can also do this from the Phone info sub-menu).

While the *#*#4636#*#* code works on various Android smartphones, you may discover that it can't be used on some devices. Anyway, be careful when accessing the hidden Testing menu. If you change something, make sure you know what you're doing. For example, if you turn off the phone's radio (this can be done from the Testing -> Phone information sub-menu), you'll no longer be able to use your device as a phone - for calls, text messages, or cellular data - unless you turn the radio on again.

P.S.: The screenshots included below were taken on a Nexus 5 running stock Android 5.1.1. Things may look different on other devices.

If you're not able to get through to the testing menu using the code, try using Google Gesture search. Merely drawing a "T" (in caps) instantly brings up Testing Menu among a few other results, and that too usually right on top. In fact not just the testing menu, but it gets you access to several other system apps/menus which are usually hidden/inaccessible.

The testing menu code *#*#4636#*#* works on the Alcatel (AIO) Conquest Model: 7046T smartphone. SPRINT WIRELESS NETWORK Actually, this is a BOOST MOBILE phone which uses SPRINT WIRELESS NETWORK. Testing menu code also works on free government lifeline plan phones only if the wireless service provider is authorized to use SPRINT WIRELESS or T-MOBILE NETWORKS. Q-Link Wireless is a lifeline service provider and their free cell phones are provided by boost mobile and the wireless service is provided by the sprint wireless network and the *#*#4636#*#* code works with lifeline free phone. You must purchase data (1.0 GB, 1.5 GB and 2.0 GB) time to surf the web from your phone and to use the testing menu address ping or change the preferred network and see the different technical information change on your device but some lifeline service plan providers don't offer data so the testing menu without data service enabled on your phone won't really show anything interesting, but if you have wifi capability the testing menu does have some wifi network information and other stuff you can check out. So, get your secret testing menu access on and do it. also, you can use the testing menu to check out what your partner who you think has been creeping been doing on his or her phone.....YES MAAMM!
