We are developing a portfolio of Visual IVR applications that operate across the 3G video call channel. We effectively present information visually and accept user input via DTMF key presses. In theory, these applications should behave exactly the same on all 3G video call capable phones and, by and large, they do but we have found 2 specific problems with Nokia devices that I’d like a view from Nokia on:
1) The E71 (that we have on loan) seems to present DTMF tones in a strange way. For each key press, we receive what looks like 2 tones. That is, the caller presses the ‘1’ key and our application sees ‘1’ followed by ‘1’. The E71 is the only devices that we have seen that exhibits this problem..
2) We just love the N95 for demos – the video out facility is superb. However, we have had sporadic problems of the applications seeming to lock-up on complex screens. This was impossible to recreate reliably until we identified that it seemed to always occur on 20.x firmware revisions. I’ve been advising our demoers to avoid this (11.x seems rock solid) but this obviously has a more serious impact on the general public.
Are you aware of these issues and how should be best interact with Nokia to address them?
