【ZenFone 3 Max 5.5】Android 7.1 Nougat update

Hellow Zentalk, i dont know where to post this but i have a major issue regarding your "model name confusion" of zenfone 3 max zc553kl. I did update my zenfone 3 max zc553kl to nougat 7.1.1. Guess what, i found some bugs on it.
1. BRIGHTNESS - the status bar panel with a brightness configuration have bugs, whenever i adjust my brightness to 75%, the scrollbar just have a ghost movement (it means that the scrollbar goes by itself.

2. MICRO SD - the grand permission is always failing, whether i copy files from internal storage going to external storage (sd card). I tried making a new folder on external storage (sd card) but it keeps on failing

so far thats the bug i've been stressed on. My micro sd card is no use in update 7.1.1 on nougat

Please correct the "model name" on your release notes of zenfone 3 max zc553kl

i hope for your favorable action to this matter

iam sorry if i post on a wrong thread

please fix your update immediately
