I want to tell the Asus company that you are unfair and spit on your fans. My phone cannot update the firmware after 217. Although I know that firmware 225 and 229 have already been released, they are not available on the website. I also want to know why Vo-LTE and Vo-wifi do not work on this phone? We paid money for your product, chose it from many other brands, and you spit on us. If this injustice continues, I will never buy ASUS again.
