Samsung released the Android 12 update to the Galaxy S21 series a few days ago. For the first time ever, even the US carrier variants of the smartphones received a new OS update on the same day as the international units. However, the update brought along a screen refresh rate-related bug that introduced some lag.
The bug causes the Galaxy S21’s screen refresh rate to revert from 120Hz to 60Hz as soon as the user’s finger stops touching the display. This causes the UI, animations, and scrolling to appear laggy and jittery. However, this isn’t the phone’s usual behavior, and the South Korean firm has acknowledged the issue as many people have complained about the bug.
An official Samsung Members forum moderator has mentioned that the team has escalated the issue, and the company is working on a fix. The bug only affects the US’s Snapdragon 888-equipped Galaxy S21, Galaxy S21+, and Galaxy S21 Ultra variants. It could be fixed with the next software update.
