Green line issue spreads from phones to Galaxy watches and fitness bands

The same display issue that has affected smartphones from multiple brands now appears to be affecting Samsung’s Galaxy smartwatches as well.

A recent report caught attention after a Reddit user named HKNworld posted photos of their Galaxy Watch 4 developing a thin vertical green (or white) line running down the right side of the screen. Another shot showed an even worse defect, including a dead pixel. According to the user, the line popped up shortly after installing the One UI 8 Watch update (or a follow-up security patch).

The Galaxy Watch 4 may not be the only model affected, either. A separate Reddit post shared about a week ago shows a Galaxy Fit 3, reportedly less than two years old, developing a similar vertical green line on its display. While it’s far too early to determine how widespread the problem is, the reports suggest the issue is not limited to a single wearable model.

This resembles the green and pink line problems many Galaxy phone users have faced after major One UI updates. Those issues are often blamed on thermal stress during the update process putting strain on the AMOLED panels.

The Galaxy Watch 4 came out back in 2021, so it’s now well past its warranty period. While it’s not yet a widespread epidemic on watches, seeing it hit older models like the Watch 4 is concerning, especially since that model already had its share of other issues, like the infamous Red Screen of Death.

For most watch owners, getting the screen fixed will probably mean paying out of pocket, and Samsung may be reluctant to offer free repairs across the board to avoid setting a precedent.

This situation highlights some ongoing headaches with Samsung’s AMOLED technology across its whole lineup. For Galaxy Watch 4 owners dealing with this, it might be time to decide whether it’s worth spending money on a screen replacement or upgrading to something newer like the Galaxy Watch 7 or 8 series. Samsung hasn’t made any official statement about the watch reports yet.

If you’re seeing similar issues, make sure to document everything clearly before heading to an authorized service center.
