##4636## Not Working on Android: How to Fix
In this guide, we will show you the steps to fix the ##4636## code not working on your Android device. The OS beholds quite a lot of hidden codes, and some of them are actually quite useful. The ##INFO## is one such code. For the unaware, it houses the Phone Information, Usage Statistics, and WiFi-Information. Out of this, our focus will be on the first one.
The Phone Information menu contains a slew of network-related information. However, it’s the ability to change the preferred network type that comes out as the most useful one. You can easily switch between 2G/3G/4G/5G or force the device to stick to a particular network, such as only 5G [NR-only]. To access this menu, you just need to input the aforementioned command in the Dialer and select Phone Information from the subsequent menu.
However, that is proving to be easier said than done for some. There are a few devices or even some OS [especially custom ROMs] wherein this command just fails to work, inputting it wouldn’t bring up any menu whatsoever. If you are also facing the same issue, then this guide will help you out. Follow along for the fixes.

Fix ##4636## Not Working on Android
Given here are four different methods that will help you get the job done. It is recommended that you try out each of the below-mentioned workarounds and then see which one spells out success. So with that in mind, let’s get started.
Via Third-Party App
There are a few third-party apps that will directly launch the Phone Information menu on the tap of a button [it will infact launch the com.android.setting.Settings$TestingSettingsActivity activity!] For instance, you may install the 5G Only Network Mode , launch it, and tap on Set 5G Only > Set 5G Only to open the Phone Information menu and carry out the required task.
Via Activity Launcher
- Download and install the Activity Launcher app from the Play Store.
- Now launch it, go to Activities, and search for the following activity: com.android.setting.Settings$TestingSettingsActivity
- Either launch it directly from there or create its shortcut on the home screen and then launch it.
- Having the shortcut on the home screen will come in useful if you are planning to use this feature more than once.
Use a Different Dialer App
You might currently be using the stock dialer app, which came shipped in with the device. Well, it’s time to ditch that and try out one of its alternatives from the Play Store. Do note that most of the dialer apps in the Play Store are filled with ads, however, so only use them for inputting the code, and you may then uninstall them right away.
Via ADB Commands
If you are unable to find the com.android.setting.Settings$TestingSettingsActivity via Activity launcher, then you can also get this job done via ADB Command. Here’s how:
- Download and extract Android SDK Platform Tools on your PC.
- Then enable USB Debugging connect your device to PC via USB.
- Now open Command Prompt inside platform-tools folder and type adb shell am start -n com.android.settings/com.android.settings.Settings$TestingSettingsActivity
- This will open the Phone Information menu on your device.
Via Module
If your device is currently rooted via Magisk / KernelSU / APatch , then this is undoubtedly the best method out there. Simply download the module , flash it via your rooting app, and reboot your device. The functionality will be added in the dialer app. NOTE: This module has been tested on OnePlus Android 15 and may or may not work on other Android devices.
