Based on the information provided the repairability of the Samsung Galaxy S25 Ultra seems to be relatively good. The use of adhesive for the back cover may make it slightly more difficult to access the internal components but the battery and battery cable are easily accessible and there are pull tabs provided to remove the battery. Additionally the screen cable and screen can be removed without having to remove too many other components. Overall I would give the repairability of this device a score of 8.5 out of 10.
