Google has officially acknowledged a bug in Android Wear 2.0 where-in keyboards for some languages have missing characters. Specifically, users of Russian and Hungarian keyboards have been noticing this problem for a few months.
Characters ‘Х’ ‘Ъ’ ‘Э,’ and ‘Ё’ are missing from the Russian keyboard, and the Hungarian keyboard is also reportedly incomplete.
Affected wearables include watches with round screens (LG Watch Urbane and Huawei Watch). Following is the statement from a Google community manager:
“Hi, Just wanted to update this thread to say that this has carefully been considered and will be coming in a future update. Thanks everyone for your feedback!”
