Widevine Digital Rights Management (DRM) standards have been defined based on device security for content protection. They are meant to prevent copying or piracy of data that these services push across the internet to their users.
Services that use DRM can stream befitting content quality depending on the security and hardware at the user end without much work on the server end.
Widevine standards integrate Common Encryption (CENC), licensing key exchange, and Dynamic adaptive streaming over HTTP (DASH) for secure transmission.
There are three certification levels: L1, L2, and L3. Your phone needs to be L1 certified in order to be able to stream HD content.
Not only Android phones but many Laptops and most Browsers on Desktop support L3 certificate only. For instance, Chrome Browser on Desktop is L3 certified and can only stream in HD using Netflix and other services.
Why Manufacturers don’t add DRM L1 certificate?
The most important point to note is that all modern chipsets are compatible and Widevine doesn’t charge any licensing fee. So, the only reason why manufacturers are ignoring this is oversight and because users are not particularly asking for this.
Can you get Widevine DRM L1 certificate with OTA update?
Yes, earlier it wasn’t possible to push Widevine DRM L1 via OTA update, but this changed after 2017. Poco F1 was the first phone to get DRM L1 certificate via OTA update.
How to check Widevine DRM Security Level on your phone?
If you want to check the DRM security level on your phone, you can simply download the free DRM Info App from Play store.
The app is pretty simple. All you need to do is open it and check DRM level under “Google Widevine Modular DRM” heading. If you see L1, your phone supports HD streaming. If you see L3, your phone only supports SD streaming. Android phones only have L1 and L3 certification.
Samsung phones – All Samsung M-series and A-series phones launched in 2019 support HD Streaming (except for Galaxy M10). Galaxy A7 (2018), Galaxy A9 (2018) from last year support HD streaming as well
So Samsung has clarify the rest....
