MinsOS v0.3.4 Updates install from Settings, and the battery page shows a measured figure. - In-device updater: reads this device's own manifest, verifies against the MinsOS OTA certificate, stages and reboots. On the T970 the bundled crypto-less recovery installs it unattended. - Battery health is recomputed from the fuel gauge at every boot; the cycle row is hidden rather than shown as a false zero. - T870: the side-key fingerprint enrolment UI renders (display layer only). - Third device: SM-T976B (gts7xl) ships alongside the T970 and T870. Verified on hardware for gts7xlwifi (SM-T970). The other two rest on the build gates and on tester reports. USB-C DisplayPort is NOT fixed in this release - the redriver change had only ever been in one of the three kernel build paths, and the shipped kernels have CONFIG_REDRIVER unset. Both local paths carry it now; it lands with the next kernel.
