This should not be categorized as an iOS 26-specific issue, as LED displays can sometimes flicker at low brightness due to Pulse Width Modulation (PWM) dimming. Disabling the PWM Dimming feature in the iPhone Settings should resolve the issue on your iPhone. But, if that does not solve the screen flickering issue, here are some useful fixes to fix the problem.

Step 3 – Then, set the Reduce Transparency setting to ON.

Step 1 – Proceed to the Display & Brightness settings.
Step 2 – Next, open up the Display Zoom settings.
Step 3 – Change the Display Zoom to Larger Text mode. Then, revert it to Default mode.
This simple refresh should fix the flickering problem that you are experiencing on the iPhone.
