Samsung Releases Galaxy A37 5G With Exynos 1480 and 5,000-mAh Battery

Q: Why might the Galaxy A37's vibrant screen pose a hidden risk for some users' eye health?

The hidden risk is the Galaxy A37 5G’s use of low-frequency PWM dimming on its AMOLED display, which can cause eye discomfort in some users even though the screen looks bright and vivid. PWM, or pulse-width modulation, controls brightness by rapidly turning the display’s light output on and off. That flicker is often too subtle to notice, but sensitive users can still react to it, especially at lower brightness levels or during long viewing sessions. Experts link low-frequency PWM to symptoms such as headaches, eye strain, blurred vision, dryness and light sensitivity. The issue is “hidden” because the display’s strong points—vibrant colors, deep contrast and high brightness—do not reveal the underlying flicker behavior. In fact, AMOLED panels are commonly associated with this dimming method, and the added visual intensity can make discomfort worse for people who are flicker-sensitive. For most users, this may not be a major problem. But for anyone prone to screen-related headaches or eye fatigue, the A37’s display could be a drawback despite its otherwise impressive quality. In practical terms, users with known sensitivity may want to test the phone in person, avoid very low brightness settings, or choose a device with documented flicker-free or higher-frequency dimming.

Samsung’s Galaxy A37 5G arrives as a modest mid-range refresh, adding IP68 water resistance, Gorilla Glass Victus+ on both sides and the Exynos 1480.
Exynos 1480 lifts everyday performance over the prior Snapdragon-based model and works better with UFS 3.1 storage, though it still struggles with demanding games.
The 6GB RAM and 128GB base model looks thin for the segment, especially with no microSD slot, while the triple rear camera brings only limited gains despite better low-light pixels.
A 5,000-mAh battery still delivers long runtime and recharges in under 70 minutes at up to 45W; connectivity includes 5G, Wi-Fi 6, dual-SIM with eSIM and strong call quality.
The phone is not a major generational leap, but its lower street price and long software support make the overall package more competitive.
