Here’s how to fix red frame or red border around screen issue on Android devices. You may face this issue if you enabled “strict mode” on your device knowingly or by mistake. I got the idea of writing about the solution of the red highlights on Android display from the comments of one of our visitors. It is meant for those who have just started with Android and also those who have been using an Android device but do not have time to delve deeper into its settings and other technical stuff. Let us see how we can fix the red border around screen of the Android devices.
Have you ever experienced a flashing red frame on all sides of your Android phone’s screen? Sometimes, this red border stays for about 10-20 second and even more. Have you ever thought about what it is and why you are seeing that red line on the four sides on your device’s display? If you are just a basic user or unfamiliar with it, you might take it for a problem with the phone’s display or LCD, a software bug, or even as an indication of some impending disaster with your phone.
So, is that red glow around the edges of your Android phone’s screen really a serious thing to be bothered about? I do not think so because it is just a tiny glitch resulted from a misconfiguration on your phone’s settings and it is known as “Strict Mode”. It is not one of those features that are meant for normal use. Rather it is a developer tool to test and analyze some technical aspects of Android devices.
Strict Mode is not found on all Android devices. It is a new feature that was added to assist developers with Ice Cream Sandwich and above. So, you’ll be able to see the red line thing only on phones with ICS, JB, Lollipop, Noughat, Oreo and possibly the upcoming Pie. It does not matter whether you have a Samsung Galaxy, Sony Xperia, Motorola, LG Optimus, HTC or a Pixel device, if it is on any of the above-mentioned versions of Android, you should see “Strict Mode” on it.
What is the Strict Mode on Android?
As I mentioned above, Strict Mode is a developer tool that detects your Android disk’s Read–Write permissions and Network processes, and then tell you via the red frame flashing and some other indications on the screen when it finds any violation of the preset rules for those processes. In simpler words, whenever there is much load on your device’s GPU It brings them to your attention so that you can fix them.
According to the official Android Developers blog,
“StrictMode is not a security mechanism and is not guaranteed to find all disk or network accesses. Future versions of Android may catch more (or fewer) operations, so you should never leave StrictMode enabled in applications distributed on Google Play.”

If you have been experiencing red glow lines or frame on the edges of your phone’s or tablet’s screen, you can disable it right from your device’s Settings interface.
- Open Settings> Developer Options and scroll down a little.
- Here you would find the Strict Mode option.
- Just uncheck/unmark it.
- And, then reboot your device.
If you own a newer Android device (the above screenshots were taken 3 years ago on a Galaxy S3), do as instructed below:
- Open Settings> About device> Software info and tap Build number 7 times.
- Doing so will enable Developer options on your phone.
- Now go to Settings> Developer options.
- Scroll down to find Strict mode and disable it. In case you don’t find the option, tap the search icon and type “Strict Mode“.
Once you disable the strict mode, the Red Border around screen on Android device will be fixed.
Another solution for disabling the Strict Mode on your phone or tablet is a factory reset but doing this will wipe all data and apps on your device. So if you go for it, do not forget to backup your data first.

In case disabling the strict mode on your Android phone or tablet does not solve the red line issue at all sides of the display, follow the steps given below. Please note that the procedure given below works only on rooted devices since it involves editing system files. That is to say, you must have root access to be able to use this method.
- Download and install a root file browser/manager app from the Google Play Store. I recommend Root Browser. Skip this step if you already have it installed: [googleplay url=”https://play.google.com/store/apps/details?id=com.jrummy.root.browserfree”]

- Launch Root Browser and open “system” directory.
- Scroll down to “build.prop” file and open it.
- Select RB Text Editor to edit the file.
- Now add the following lines at the end of “build.prop” (see the screenshot):
- Finally, tap the Save icon on the top bar to save the changes.
- When you are done with these things, reboot your phone for the changes to take effect.
