To address this, 100ms offers dogfooding sessions where their customer success team tests customers' apps before rollout. This involves understanding end-users' setups and simulating stressful network conditions. The blog presents a case study of a dating app that faced issues with video resolution dropping frequently on slightly older Android/iOS phones. Through dogfooding, 100ms identified the issue as CPU limitations in these devices and adjusted the publish layer settings accordingly to improve video quality.
