I have the same issue. Basemap works well on desktop and on various mobile phones. But just on my ASUS zenphone (support webgl2), it shows a blank earth at initial low zoom level. After zoom in to certain level, it can show correct basemap tiles. But when I zoom-out again, the globe goes blank.
Enable USB debugging cannot find anything weird in devtools, as it works well in desktop.
At an earlier development it ever worked on my phone. But after that, most of the time I tested my codes on desktop, and cannot make sure which version it cannot work then.
I had tried some parameters such as globe.maximumScreenSpaceError or tileCacheSize, unluckily no help. I still cannot find its possible cause. I know these descriptions cannot help to solve this problem, but maybe someone has suggestions/comments to debug this.

Thanks @webdq and @cywhale! I've reopened the issue.

If at all possible, it would be helpful if you could determine the version number where this behavior started happening.

Ok I can make a trial by git reflog/reset to my older development version, but not sure if I can reproduce it. Some extra time would be required. If any updates for this, I'll report here.

@ggetz Now I can confirm the changes come from v1.92 (everything ok) to v1.93 (go wrong, become blank globe at initial zoom, and after zoom in to certain level, it can show correct basemap tiles). I also test v1.87.1, v1.91, both ok. After v1.93, 1.94, 1.95, 1.99, 1.100, and to current release, all shows blank globe on my phone (ASUS X001D Android 8.1, support webgl2), and not work on other phone (Android, much newer version, Samsung A53) . But all these versions work well on desktop, and work well on other phones.

Thanks @cywhale! That helps! This is likely due to shader changes that went in as part of #10063. The next step would be to identify what part of that is causing different results on these android devices.

@ggetz then I found this issue related to #10442 and set scene.globe.showGroundAtmosphere=false can make the globe correctly shown on my phone. It's a temporary solution.
