I've recently purchased this phone from ebay and didn't realize that this phone is permanently stuck on the android 7.0 which limits so many current apps that I currently use on my other phone asus rog 2. I bought the AR model as my secondary phone but didn't realize that I can't upgrade to OREO android 8. I would like to know if anyone has any information about his particular phone in regards to being able to update the firmware to at lease OREO/android 8 or even safer security patches? Official ASUS representative response would be appreciated. Thank you
