The performance of the device has significantly improved following the installation of Lineage OS, effectively resolving previous issues related to outdated hardware. My primary concern, however, pertains to the HDMI output functionality. Despite the device recognizing both the television and mobile display, no image is being transmitted in either mirror or desktop mode. Upon initial activation, selecting desktop mode resulted in a device restart. Subsequently, neither desktop nor mirroring options have yielded any visual output.
Do you have any recommendations for a modified kernel or alternative firmware, ideally as lightweight as Lineage OS, that might address and resolve this HDMI functionality issue?
