Samsung Galaxy Green Line Bug Fixed in Latest Update

Samsung Galaxy S phones seem to be suffering from a bug that displays a permanent green line across the display following the April security patch.

A number of Samsung Galaxy phone owners have reported a concerning bug where a permanent green line appears on the display after updating to the latest security patch. This issue is prevalent across models such as the Galaxy S22 Ultra, Galaxy S23+, and Galaxy S26, with evidence shared by users on Reddit.

This issue is not limited to a specific model and has been observed even with the latest Galaxy S26 after updating to the May security patch, indicating a potential underlying problem in Samsung’s update process.

Although Samsung has not yet addressed this issue, there is a significant amount of discussion online regarding possible causes and preventative measures.

What’s the issue?

A post from last June on the official Samsung community website indicates that the green line issue is not a new phenomenon.

One user suggested that this could be a screen burn problem caused by overheating. Suggestions to address this range from avoiding updating the phone after long gaming sessions to extreme measures like placing the phone in the fridge during the update process.

It is important to note that extreme measures like placing the phone in the fridge could potentially cause damage, so caution is advised.

Other recommendations include charging the phone before updating, then waiting for it to cool down before initiating the update process. Removing the phone case and updating in cooler conditions, such as at night, are also suggested strategies.

We will continue to monitor the situation and provide updates as soon as Samsung acknowledges the issue. In the meantime, it is advisable to approach phone updates with caution.
