I've noticed that I have trouble with the sensor when I am in a position with the light source on an acute angle in relation to the screen/sensor strips.
Taking this into account the light source should be as close to 90° as possible in relation to the screen to have a minimum effect on the sensors. Well, this is the theory....
As well, in bright sunlight in most cases the sun is high over head and not on an acute angle.

Hmm, this has me wondering what sort of touchscreen they use. Mostly you hear about resistive and capacitive. I had not heard of an infrared one on portable devices. Seems a strange choice if it is effected by light.
