Alert: Galaxy A70 Android 10 update has a hardware-breaking bug
In the last one month or so, a lot of Galaxy devices have been updated to Android 10. It’s almost been an avalanche, in fact: earlier this week, no less than three Galaxy smartphones got Android 10 along with One UI 2.0 on the same day. While it’s great to see that Samsung is trying to push out the Android 10 update to as many devices as quickly as it can, it seems the company is not testing the update as much as it should and is letting a few bugs slip through.
A hardware issue that requires a trip to Samsung’s service center
Unfortunately, according to our sources, it’s a hardware problem. From what we’re told, Samsung has used two different versions of the printed circuit board (PCB) that handles charging and controls the screen on the Galaxy A70. This PCB is updated along with the motherboard every time a software update is installed, but the process fails to complete with the Android 10 update because Samsung apparently forgot to include the necessary code for Galaxy A70 units with the older version of the PCB.
In simple terms, it means that on some Galaxy A70 units, installing Android 10 results in a mismatch between the software on the main motherboard and the charging PCB, and that makes the phone think the battery isn’t charged and prevents it from booting. And the only way to solve this on devices that have already been bricked is to replace the older PCB with the newer version, which means the device needs to be taken to a Samsung service center.
