If you are content with the string data you read from the device and believe it’s format is correct, you may try to validate the two strings with String class and use the return value with assertTrue.
Link below mentions assertEquals(Obj, Obj) does the same thing with String.equals(""), so maybe you can check if you are using assertEquals(Obj) instead of assertEquals(char [])
(And does “\n” stays the same with different device sizes? It might move or dissapear completely if there is enough space for 1 line)
