Tips
- You can change your phone's DPI level with various apps, but your device needs to be rooted for these apps to work.
- You may see distortion in your device's keyboard after changing the resolution. To work around this, install a keyboard that can follow the device's DPI (eg GBoard).
Warning
- Sometimes, DPI changes cause compatibility issues when you use Google Play Store to download apps. If you experience this kind of problem, change the DPI back to the default setting, download the app, and change the DPI again.
- While you can increase or decrease the screen resolution to enlarge or reduce the content on the screen, you cannot increase the device resolution to a higher definition level (eg “720p” to “1080p”) because the screen definition is determined by the physical screen of the phone itself.
