I tried it last year and it was not usable for me, even though the screen was PWM-free when recorded on a slow motion camera, it was worse on my eyes and harder to read than even the OLED iPhones. The screen also always felt too bright even at lower brightness, and in particular one half of the screen was even more straining to look at than the other (forgot if it was the left half or right half).
The A98 5G I tried was on Android 13 so the issues were not related to Android 14. Even tried to mess with the dynamic refresh rate with SetEdit after other tweaks failed, in order to lock a specific refresh rate, but each FPS I tried locking it at (30/50/60/90/120fps) basically each generated a "different feeling and variation of the eyestrain" but never improved it.
It's a shame because aside from the kinda too large size and the lack of bootloader unlocking support, everything else about the phone worked good, great performance and speaker quality for the price, but the screen was so bad.
This was one of 4 LCD phones I tried last year, all were unusable to me.
The other 3 phones were the Xiaomi Mi Mix 2s (slightly better than A98 but still very strainy), OnePlus Nord N30 (even worse screen than A98 even though the other specs are very similar) and the iPhone SE 2020 on iOS 17 (the absolute worst out of all of the LCDs).
