This HDR brightness issue still persists in 2025 on the Nothing Phone (3a).
Toggling HDR Display ON or OFF from Settings > Display makes no visible difference—at least based on testing with HDR videos on YouTube, though you get watchable brightness while watching HDR videos on YouTube regardless of the setting.
However, the problem becomes very noticeable, worse when streaming HDR content on the JioHotstar app using a 4K UHD subscription.
Movies like Jungle Cruise and Mufasa: The Lion King appear extremely dim, making them almost unwatchable.
Strangely, when using the same device but logged into a 1080p-only Hotstar account, the same movies play with normal brightness and are perfectly watchable.
This issue seriously affects my multimedia experience, and it’s becoming extremely frustrating on a phone that is supposed to support HDR10+.
Please — if anyone has found a fix or workaround, I’d be truly grateful for your help. This is genuinely disappointing for an otherwise excellent device.
