Green line display failure and back panel adhesive separation

After 2.5 years of light use (mostly YouTube/Reddit, always cased), an S23 Ultra developed a spontaneous green line. Owner also found back-panel separation where adhesive failed, more noticeable when using a 45W charger. Estimated authorized repair around $200–300 and weighed that against buying a cheaper replacement phone.
