Compatibility #1
Comments

@MavenW no its not compatible with Note10 Lite SM-N770F, only compatible with S9 / S9+ / Note9 Exynos |
mmm so could I compile a new version of ApolloKernel compatible with the Note 10 lite? I thought it was compatible because I saw the name of the device in the list of changes. |
|
@MavenW this kernel source is based on stock Note9 kernel, only added/updated stuff from note10 lite according to our needs. so im pretty sure you cant make it work on note10 lite without efforts / proper driver and stuffs. |
