Ok, so you're running Android 4.0.4 - Ice Cream Sandwich (API 15) - flavor: rocks
And your device is providing the following info to KO:
framebuffer resolution: {
["h"] = 1152,
["w"] = 825
}
But that's not the real resolution, which is: (1200, 825)
This can be solved with a patch, but first: can you confirm that the last version that shows a fullscreen is 2019.03 and the first version with a white space is 2019.10? Do you see a koreader logo while uncompressing assets?
The patch (save as /sdcard/koreader/patch.lua):
Code:
local screen = require("android").screen
screen.height = 1200
