Hi Satish, Thanks for your reply, but:
1. This is not a screen density issue, it's a screen resolution issue. I *think* that Android doesn't know that the kernel's framebuffer can now handle 800x480 so it asks for 720x480. 2. https://android.googlesource.com/platform/frameworks/base/+/android-6.0.1_r70/core/res/res/values/config.xml contains no mention of 720, and 720x480 is the (unwanted) working resolution.
