Your G force meter looks a little bit off with 0.6G of acceleration and only 0.6G of braking. I think that should be more like 0.2G of acceleration and 1.0G of braking.

Is there a way to fix this calibration?

Lap List -> Lap -> Recalculate -> Acceleration. I'd not recommend to do it in this case, as the measured values are well readable. Calculating acceleration from GPS is always a compromise.

I helped SKeijmel with this overlay. The overlay is rendered onto a clean blue screen on the Samsung Galaxy Note and then overlayed onto the GoPro video recording using Final Cut Pro X. The overlay from the Samsung phone seems to be a little bit glitchy. Renders from my own iPhone 5S are generally smoother. Is that due to the Android version being relatively new and not as optimized yet? To give an example, look at 1:41 in his video. There is a sudden countdown glitch in his overlay for only a tenth of a second.

I consider this a general challenge in Android. Video libraries and OS versions and hardware fragmentation does not allow optimization to a level Apple can achieve. Maybe it gets better once I add support for Android's video functions introduced in 4.3...

almost but its just wide;)

Likely the yaw angle calibration is off. Go to charts for the lap and look at the total G plot. It should have a relatively flat top that is parallel to the lateral acceleration axis. If it's tilted, and I'm betting that it is there are small buttons on the lower left that will rotate the plot. The center button should fix a major error and then you can tweak with the left and right buttons which rotate the plot in 2 degree steps. Recalculating the acceleration from GPS data is a last resort.

Here's a Multicam video with the new timer view in action:

Great video Alex and congrats to you new best! The digits are huge, aren't they? I thing the winning/losing indicator is still a bit too noisy, I will check if a smoothing is necessary or if I should simply make the "neutral" range a bit bigger... I assume this is a little too much indication to be helpful? Which GPS have you used, the 20 Hz VBOX or the internal GPS?

VBOX Sport @20Hz. I guess it's the same noise you also get on the speed display...if GPS reception quality drops you also get spikes like >300kmh with the VBOX Sport.
