Motherboard failure after One UI update (lag, heat, flicker)

Motherboard

Source-linkedVerify source — Reddit post

After updating a Galaxy Tab S9 to One UI 8.5, the tablet later developed severe lag, delayed touch, heating, and screen flicker. Service center formatting and an unreleased update did not fix it; technicians concluded the motherboard was cooked. Device still networked and transferred data but remained laggy and glitchy on-screen.

Source-linkedVerify source — Reddit post

After about two years of use, a Galaxy Tab S9+ developed a huge green line after gaming and a nap, with no clear impact event. Out-of-warranty screen repair was quoted around $300 in the Philippines; owner declined repair and trade-in options as unaffordable and noted the lines grew larger after unused days.

While lying in bed scrolling, a Galaxy Tab S9 screen separated from the back panel and the tablet went black. It stayed connected to a mobile hotspot briefly but would not power on afterward. Device is out of warranty; owner reported no visible inside/outside screen damage and asked whether reattachment is possible.

Intermittent green line near fingerprint sensor

11 months

Source-linkedVerify source — Reddit post

Galaxy Tab S9+ about 11 months old showed a green line flickering near the fingerprint area for a split second in darkness. Owner planned a warranty visit before coverage ended. Commenters with the same model reported similar random dark-mode green-line flickers, sometimes after a One UI update, with no drop history.
