It did suspend the update’s release temporarily as a further investigation was underway. The affected phones were shipped to its headquarters in Suwon where the investigation found that this was an isolated case. The device that suffered this issue had a counterfeit PBA (main board) which likely caused the code mismatch.

Given that this was an isolated case and there have been no widespread complaints about this from other Galaxy A70 owners, Samsung says that if users experience a similar issue with their phone, they should get in touch with the company’s service center.

The Galaxy A70, the Android 10 update has a major issue that bricks the device and stops it from booting. 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.

If you own a Galaxy A70 and are still running Android Pie, we would recommend not updating to Android 10. If you have already updated and your phone is running fine, then you don’t need to be concerned, though we would still suggest that you refrain from installing any future updates for the time being.
