Hi team, I have a ZTE axon phone with lollipop 5.1.1. I'm trying to install other system languages but there is no option available to do so. I just checked for system updates and rebooted my phone but there are no new system updates. The only languages available are English, French and 2 other languages that appear to be Chinese and Japanese. There is no option to search for new languages. I have seen screenshots about there being a plus button to install more but I don't have it on my phone. Any suggestions?
