Nexus One phone touch screen has serious multi-touch problems
On March 4, according to foreign media reports, "Android and Me" published an anecdote about the touch screen of the Nexus One phone. Obviously, there seems to be a problem with the multi-touch of the touch screen of this mobile phone on the same line. This problem was pointed out by game developer Robert Green. He encountered this display problem when developing games. To illustrate this problem, he made a "multi-contact visible test" application.
This app shows how your phone hardware handles multi-touch. This event data is not processed in any way. When you touch the phone display, the two points you touch will be drawn on the display. For many current Android phones, there are also many bad data, such as the effect of axis rollover and proximity to the axis.
Nexus One's touch screen problems will reveal its ugly appearance in touch screen applications such as ToonWarz games. This has stopped many developers from making high-quality games for Android. When one virtual game joystick is on the right and the other is on the left, many gestures affect how a game operates. It is impossible for the game to run well.
Google engineer Dianna Hackborn responded to this question in the Android developer group. However, her answer does not sound too good. She explained that Droid (without this problem) and Nexus One have different hardware sensors, so that they respond differently to touch. It is unclear whether the software upgrade can solve this problem. However, according to her, software upgrades do not seem to solve the problem.
It will be interesting to see if Google will make a formal response. This touch screen failure is likely to leave many Nexus One users away. Many Android phones use cheap display screens, and most of them will have this problem. Perhaps this is why Google has postponed the multi-touch gesture function for so long.
The correct harness can improve the overall performance of the different headlight parts and increase the lighting output of the headlights. Some harnesses are designed to complement higher performance bulbs. So if you have recently upgraded your headlights, you might need a new harness to keep the new lights performing efficiently. When looking for a new harness, you need to be sure that all the parts of the headlight wire harness kit are of the finest quality-not only the wires but as well as the relays, sockets, and terminals. The parts should be tough and must not be susceptible to burning. Also, check whether the harness is compatible with your vehicle.
