Nobody else has reported this issue, do you perhaps have an older phone?
I've got a LG K40 running on one of the newer Android os. My first assumption is that it's a screwup that happened at the download, but it persists after I updated it and also reinstalled the game. I'd give you a proper bug report from my device but I honestly don't know how I'd go about accessing the game's core files neither how to read JavaScript or any other digital language.
