Mobile technology has made great strides in the past 20 years. There is hardly any individual who does not own a smartphone or tablet. The wide offer available allows you to choose between various devices, almost for all budgets. Android devices are among the most popular, and they are also among the easiest to customize. Android is in fact a very versatile operating system, the preferred platform of independent developers. The changes we can make to the system are manifold. For example, you can change video resolution android. To do this, we will need to access the developer options. Let’s find out how.

Steps to change video resolution android
- An Android device
- Universal USB cable
- Windows operating system
Enable USB debugging
We access the device settings by touching the gear icon. We go down to the “Device info” or “About” item. If we have a tablet, the entry could also be “About tablet”. We locate the item “build version” and quickly touch it seven times. This will give us access to the developer options, which we will find accessible by returning to the previous menu. Within the developer options, we activate the “USB Debugging” item, and we give OK when requested.
Install Android Studio
Now we will need an app for Windows: Android Studio. We can download it from the official website, and it is also available for Mac. The program allows you to develop Android applications, but also to change the system settings of the device. We install the program on our computer following the guided procedure. We complete the procedure by clicking on “Finish”. So let’s connect our Android device to the computer. We wait for the system to detect the device and authorize the communication between the two hardware. To do this, just touch the OK button to the request on the Android device.
Use commands via prompt
Now we will have to work a little with the commands. We start the Windows command prompt and insert this line: “adb shell dumpsys display | grep mBaseDisplayInfo”, without the quotes. We send to get information on the Android device. Among the information, we will have to identify the entry “density”, followed by a number. It is the current resolution in DPI, or in dots per inch. We write down the figure, so we can restore it in case of errors. We insert the following command line: “adb shell wm density [DPI] && adb reboot”, without the quotes. To the “[DPI]” part we replace the new figure in DPI, so we send it. This will restart the Android device with the new resolution.
It is always a good precaution to make a backup copy of your data on your mobile phone. These procedures always have their risks, especially if not an expert is performing them.
