In early May, Samsung released the April 2020 security patch update for the Galaxy M31. Unfortunately, some devices were bricked up. Of course, the company had to reset the OTA. Now the update is released again.
The new update contains a different build number and a smaller package size. It is 395.40 MB in size and has the build number M315FXXU1ATD5. The old update had a size of 541.26 MB and the build number M315FXXU1ATD1.
The new Samsung Galaxy M31 update is now being introduced for devices that have successfully installed the previous April 2020 security patch update. However, you should be careful to install the update until it receives positive feedback from more users.
