note8 lte 升級

想問note8 lte 升級4.2.2 或 4.4.2 好,有冇 ching 刷過英版 4.2.2 有冇乜大問題?thx

for use miband, note8 lte (HK) just 升級 英版 4.4.2 (use odin to flash, so easy)
- have traditional chinese, but not HK traditional chinese
- have samsung chinese input method (but handwrite cannot full screen), then better to use google input
