Xiaomi finally admitted that the REDMI K90 Pro Max has a nasty camera bug, and they’re supposedly rushing out a fix. If you’re on the latest HyperOS beta (build 3.0.18.0) and your camera app keeps faceplanting, this is why.
The weird part? The camera works fine for regular photos. It only dies the second you try to load your saved Pro Mode presets. It’s a classic software "regression"—meaning they patched one thing and accidentally broke another.
What to do right now
Xiaomi has tracked this as Bug #52644009 and they’ve already reproduced it in their labs. A patch should be coming in a few days. Until that "1.1" update hits, here is how to keep your phone from losing its mind:
- Don't touch your presets: If you need to use Pro Mode, you’ll have to dial in your ISO and shutter speed manually for every shot. Just don't tap those saved shortcuts.
- Skip the factory reset: This is a code error in the beta, so wiping your phone is just going to waste your afternoon. It won't fix the bug.
- Watch the updater: Xiaomi usually prioritizes app-breaking bugs like this. Keep checking your system settings for a small incremental patch.
The K series of the REDMI devices are exclusive to China, and their counterparts usually come under the POCO brand for the rest of the world. Therefore, this particular problem affects only the Chinese beta firmware and doesn’t affect the global models at all. But if you’re importing or running the dev ROM, just hang tight.
Key Points
- Targeted Bug: The crash is specifically hitting the REDMI K90 Pro Max on beta 3.0.18.0.
- Pro Mode Trigger: The app only force-closes when loading saved manual camera presets.
- Code Regression: Xiaomi confirmed the issue is software-based (Bug #52644009), not a hardware defect.
- Fix Status: Engineers have reproduced the error; a patch is expected in the next incremental update.
- Regional Issue: This glitch currently only affects the Chinese beta ROM, not global versions.
