Galaxy A34 users report Netflix video streaming bug after a recent update

Most smartphone users look forward to software updates, as they promise to bring new and improved features, better performance, and improved privacy and security. However, not all software updates are built the same way. Sometimes, updates can cause issues, and one such issue is being faced by some Galaxy A34 users.

Some Galaxy A34 users from Latin American countries like Brazil have reported to us that a recent security update has caused video streaming issues on their phones. They have noticed severe video distortion while using USB Type-C headphones or adapters while streaming videos. This appears to be happening while using Netflix and other video streaming apps.

This issue is likely related to the failure of the Widevine L1 handshake procedure while using the USB Type-C port for audio. This is reportedly forcing users to choose between using headphones or watching the videos in SD resolution rather than Full HD or HD resolution. This happens when a device fails to get certified at the Widevine L1 security level and falls back to the L3 security level. We found a similar issue logged on GitHub, and it seems to be related to the MediaTek chipset used in the Galaxy A34.

If this issue is due to the MediaTek chip and its Widevine L1 certification, only Samsung can solve the bug via a software update. If Samsung has received this issue, it could already be working on it, but we don't have any official information about it as of now. Hopefully, the next software update fixes it.
