Hi,
Can you fix the invisible text in New task and detail description. and in some menu. I cannot see the text as it's white on white. Or typing text white.

Yes. This sounds like a mobile UI/theme issue, particularly if the problem occurs on a Samsung/Android device where text is rendered white on a white background in New Task, Description, and some menus.
Microsoft supports Light/Dark/System appearance in Power Apps mobile on Android, so the first thing I would test is the device/app appearance setting.
troubleshooting
1. Change Power Apps Mobile to Light mode
On the Samsung device:
Power Apps → Profile picture → Settings → Appearance → Light
Don't use System default for the test.
Then completely close Power Apps and reopen Dynamics 365.
If the text becomes visible, the issue is most likely related to dark-mode/theme rendering.
2. Check Samsung Dark Mode
Temporarily disable:
Samsung Settings → Display → Dark mode
Then reopen the Dynamics 365 app.
Also check whether High contrast / accessibility settings are enabled
