If you have any ideas of how to deal with this from within angular in a fair and balanced way, I'd love to hear it. But I'm not so sure such a way exists.

I think it's very important find a way to fix it because now it's impossible update stuff while using an Android mobile keyboard and it'is unacceptable : For example, now I'm developing a auto-complete component and as you can imagine I need the model is updated and it's not until i close the keyboard or click on the "confirm" button. If you don't want to remove the feature might you give us a little patch that we can include in our projects?

I've personally been experiencing this behaviour on web apps which aren't angular-based, such as github on my android phone for ages now, and this is actually the closest I've come to really explaining why it happens! I don't know, I don't like the idea of hurting people with CJK requirements or anything, but I agree that it's not really a good thing.

It's just that there probably isn't much we can do about it from within Angular while still supporting complex IMEs. Hi clkao , could you verify that this is working as expected? However, the model value should not change until the correct accent was chosen. Your PR does not break the fixed behavior of , so I will merge it. Cool yeah it's working well for me with Swype on Nexus too, so just hopefully it doesn't break any internationalization features, since I think it's only really been tested with latin IMEs.

Chrome does auto correction of things that are typed. It fires a compositionstart event when a word is started and a compositionend event when the word is finished, e. So even with the PR from caitp the scope value is not updated until the end of the word! So if we want to have updates on every key press we need something else But that's a bit bothersome. We could try and update the model on compositionupdate, but that seems like a bad idea. On the other hand, is waiting for a complete word really that bad?

Since it's mobile, fewer digests might be for the best. I think we need to revert the commit for and postpone that until PR is merged. Chrome auto completion or IME input. If we revert the change, we need to reopen and link it to PR ! The issue here is: mobile input correction being compositions but immediate updates are desired. I think a good compromise is that we still send out updates for ascii characters even during composition on keypress event , so it works as desired for all cases without configuration.

It seems the mobile browsers and individual IME vary quite a lot. On my android 4. Or alternatively, it could be decided that model updates on autocomplete are not that bad, as this means fewer digest cycles on low-powered devices. Just a side note: checking the characters does not help in this case. When using a Chinese locale on a US keyboard we only get normal us characters until the compositionend event, which replaces the input's value with the Chinese characters.

Sadly both events send out keycode 0 on N5 chrome for tested by walkingice earlier today. So this really comes down to what caitp said about autocomplete or auto-correction and model updates. And in this case, based on the use of the API, the new builtin text service on android or chrome for android seem to decide that incomplete english texts aren't intended values.

Ok, thought about it a lot and I agree with clkao that we should just disable this for Android. I double checked for iOS and it does not fire composition events for word completion suggestions. The native mobile safari on android 4. Having this remained "broken" for android for now is probably better than this reverted and be broken everywhere else ;. Ok, let's do it. I took the PR from clkao and added a missing test. Will merge when ci is green Thanks all, specially caitp and clkao!
