Netflix has added the Asus ZenFone 6, ROG Phone II as well as the TCL 10L and 10 Pro to its list of HD-compatible devices list. In addition, the ROG Phone II and TCL 10 series phones have gained HDR-10 playback compatibility.
In order to view HD and HDR content on streaming apps on your phone, you need Widewine L1 certification but even some devices with this certification are not eligible if the streaming platform doesn’t explicitly whitelist them as was the case here.
Thus it seems Netflix and other video streaming apps have their own criteria for whitelisting phones so its recommended to use a digital rights management (DRM) app to check your phone’s certifications or better yet try to load up HD/ HDR content directly.
I fully converted it to now be updated with Worldwide patches, no longer Chinese patches.
Asus botched the Zenfone 6 distribution so bad. For the first few months, their site was sold out. Then they had it for MSRP for maybe a month. Then ever since--sold out. Amazon and eBay sellers are selling them for 50% over MSRP. We're talking 64GB ...
It runs on Chinese ROM.
