To access information related to your smartphone's history, including details about recently used apps, you can use a specific USSD (Unstructured Supplementary Service Data) code: *#*#4636#*#*. This secret code provides access to a menu often referred to as "Testing" or "Phone Info," which contains various diagnostic and information options, including "Usage statistics" where details about app usage are typically found.
Understanding the Smartphone History Code
The USSD code *#*#4636#*#* is designed to reveal a broad range of information about your smartphone's internal workings and history. While it doesn't exclusively display "recently used apps" as a standalone feature, it grants access to the "Usage statistics" section. This section meticulously logs how frequently and for how long each application has been used, effectively serving as a comprehensive record of your recently used apps and overall app engagement. This aligns with its description as a code that "will reveal the entire history of your smartphone."
How to Access Your Smartphone's Usage History
Accessing this hidden menu is straightforward and can be done directly from your phone's dial pad.
- Open the Phone App: Launch the default phone dialer application on your smartphone.
- Dial the Code: Enter the USSD code
*#*#4636#*#*into the dial pad. There's no need to press the call button; the menu should automatically appear once the last character is entered. - Navigate the Menu: Once the "Testing" or "Phone info" menu appears, look for an option like "Usage statistics." Tapping this option will typically display a list of applications with their usage data, including recent activity.
