How to manage app scaling and display issues on Samsung Galaxy Z Fold 8

What happened

Samsung unveiled the Galaxy Z Fold 8 at its Unpacked event in July [1]. While the device features App Continuity to allow seamless switching between the cover and internal displays, some users are experiencing scaling issues on the internal 4:3 screen [1].

Specifically, some owners have reported that apps do not always adjust correctly to the internal display’s dimensions [1]. One reported issue involves the YouTube app, where video thumbnails appear misaligned, oversized, or undersized [2]. This YouTube glitch has been noted on both the cover screen and the inner display [2]. Users on Reddit and Samsung’s community forums have observed that some thumbnails resize automatically while scrolling through a feed [2]. It is currently unclear if this bug is caused by the YouTube app or the Samsung hardware [2]. Samsung support has requested screen recordings from affected users to investigate the glitch [2].

Who is affected

• Some Galaxy Z Fold 8 owners are experiencing app scaling issues [1].
• A group of users has reported misaligned YouTube thumbnails [2].
• According to a poll by Android Authority, 20% of respondents noticed the YouTube thumbnail issue, 20% saw it intermittently, and 60% reported no issues [2].
• The YouTube issue does not appear to affect all users, as some report no problems at all [2].
• One user noted they did not experience these specific YouTube issues on the Galaxy Z Fold 6 [2].

What to do next

To manually adjust how an app scales on the Galaxy Z Fold 8, users can follow these steps [1]:

• Navigate to Settings > Display > Aspect ratio (or Settings > Apps, depending on the One UI version) [1].
• Select the specific app and choose between full screen, 4:3, or 16:9 [1].
• Note that apps running in the background may need to be restarted after this change [1].

Alternatively, users can use this method [1]:

• Press and hold the app icon.
• Tap the info button in the top right corner.
• Select App aspect ratios and choose a default setting.

Regarding the YouTube thumbnail issue, one user suggested that clearing the app’s cache and storage and then reinstalling the app might resolve the problem [2].
