First of all, you need to confirm which app you purchased, the Dev Tools App or the Dev Tools Pro App? They are two separate apps.

If the purchased item is "Pro Version-Lifetime (Dev Tools(Android Developer))", it means that you have purchased the Dev Tools App; If the purchased item is "Dev Tools Pro (Developer Tools)", it means that you have purchased the Dev Tools Pro App.

If you purchased through Google Play, please:

a. Install "Google Play" App and open it,

b. Login to "Google Play" with the google account you used to purchase Dev Tools or Dev Tools Pro,

c. Click the "Account" menu in the sidebar and click the "Purchase history" submenu to ensure that you can see the previous purchase history,

d. Restart "Dev Tools" App if you purchased this one.

It should be able to be used normally. If it still doesn't work, please feel free to contact me by codekk.com@gmail.com

4. Why do the phone screen flashes or other “faults”?

If some features are turned on that cause the phone screen to flash or other “faults”, don't worry, it will not damage your phone. These are the normal features provided by Google’s official for developers. You can visit Android Developer Options.

There are three ways to recover:

5. The Layout Inspector is sometimes inaccurate

If you access an app A from the recent visit list, the layout viewed by the Dev Tool's Layout Inspector may still be the layout of the previous app B. There is no particularly good solution to avoid this. You can click the desktop icon of the app A on the desktop again, and then use the Layout Inspector of the Dev Tools to view it.

Phenomenon: Through the "SysUI Tuner" feature of the Dev Tools App, select "Show hours, minutes, and seconds" for the time, but the status bar does not display the seconds.

The Dev Tools App only provides a shortcut, and whether it can take effect depends on your mobile phone system. If it's not displayed, it means that your system does not support it. Many mobile phone manufacturers have castrated this feature, such as Samsung, Xiaomi, Huawei.

Supported models: Pixel phone, Oppo phone, Vivo ORIGINOS phone, OnePlus phone, Oppo tablet, Vivo ORIGINOS tablet, and phones and tablets loaded with Android native systems all support this feature.
