Accelerometer sensors lag

[ranco]

I have a game using the accelerometer sensor to control an item's movement. The game itself is very short - up to 2 minutes, so the known memory leak in the sensors API is irrelevant.
First game works great. When the game ends, the user has to input his/her name in a text field. When the text field is in focus, all timers/callbacks are stopped, and the accelerometer data seems to be accumulated in some sort of an internal buffer (maybe it related to the memory leak issue which we are all waiting for a solution!). I know that because when I choose "Replay", there is an annoying lag between the device's movement and the item's.

If the user is quick to enter it's name, it's a non issue - the sensor readings are not accumulated.
But if it takes time, or if the device is an N97 (and therefore the text input field is in focus longer), the lag appears. This is, BTW, the answer to a previous post I wrote in the past (http://discussion.forum.nokia.com/fo...d.php?t=196486) about N97 performance issue.

So - I'm looking for a creative way to solve it, either to empty somehow this buffer, or to limit the time the text field is in focus (specifically on N97), or anything that could solve this problem. I can't release this game before I solve this problem (at least not for N97), and it is a shame!

Any idea will help,
Thanks,

According to my observation, Once the text field is selected than it cannot listen to any callbacks as u mentioned.But if the text field got a focus only , then it can be changed but it is not of use because by clicking or pressing a text field we mean selecting a text field (not only focusing). The two things which MAY help u avoiding this situation :
1- Create ur own text field with a custom keyboard and a dynamic text field , than just limit it by time.
2- Try to unload the accelerometer service using UnloadService, once there is no use of accelerometer.

Well, I thought of the first solution and decided it is too complicated because I wish to maintain multi-lingual support and too lazy to write that.
Second solution - I found and implemented that earlier today and it works fine on my 5800 (I even know that the function call returns "true"), but surprisingly, although sensor service is unloaded when game is not active, there is still a delay starting on the third game. I think I'm give up on the N97 - something is rotten there!
Thanks for your reply,

Yes, I remember. Already been there - sorry, but that's not too good recommendation. Widgets are SO SLOW, the game is not responsive in all aspects, not just sensors. To me it seems a definite N97 bug that can't be handled. Give up on this device.
