Re: Try this screen test with your EVO and report back

Also, it seems like some phones definitely have a problem and others don't. To those that that have the problem, can you check what hardware version your phones are? Mine is version 0003 without a problem. My Google I/O Evo was version 0002. Maybe there was a bug in the earlier version after all.
Mine is also a Google I/O Evo version 0002. For those that are familiar with oscilloscopes, its similar in respect that a floating ground skews all output parameters. Values will jump. You can witness this occurring using the 3 apps I mentioned in the first post. I suspect this is what is happening with some of the EVOs touchscreens. also hero, droid incredible. Is it a batch issue? calibration issue? who knows at this point. I've only seen it reported on HTC devices. not moto or the other brands. correct me if i'm wrong.

Also if someone has a good camera to record this and showcase it running it through a gamut of scenarios. I would use my evo to record, but thats the device in question. ;p
