In the lower part of the capacitive touch screen was hard to be recognized and higher than they should be. Why might that be?

There is a Chinese phone on Android with a capacitive screen. First, the touch buttons were pressed hard, as it turned out should be a little higher to press and it was OK. But it's got so that at the bottom of the screen, press does not react, for example if you pull from the top where the clock down, then it shut up it is not always possible to cling to that part that you have to do is click ago.


Put the program showing the point when pressed with your finger. Multitouch works, the top edges of all good, where pressing on it and shows and about 1 cm from the bottom, if the lead from the top down, then the point moves slower and stays where it is 5mm higher, though the finger is already on the edge almost touches the buttons. That is, inaccessible area of the bottom 5 mm (but it is changing, more on that below). Clicking there (it should be noted with difficulty) is pressed above. For example, the thumb is able to do (though the above is pressed), but the little finger do not work, although all the above works and from the little finger.


Also noted, if the bottom of the screen to RUB with a finger, the pushing is reduced, that is, even in to keep one finger to move the other from side to side and see how the point is reduced. By the way, in the same lower part if keep the finger, and the second click anywhere, then the point is also lowered to 10-15 pixels, and when the second finger is removed, then goes back up again. It is therefore possible to pull the strip with two fingers (as the area below it turns out), but one does not work if you do not RUB from side to side...


Can you please tell what could it be? The phone was disassembled, nothing special noticed, cleaned from dust, collected works, that is not picked up, the tape stripped, got everything exactly as...

If nothing can be done except buying a new touchscreen, maybe someone knows how to Android 2.3 to make the bottom nothing is displayed, so you can cut the screen on the pixels 20, and there and the keyboard appears and buttons in programs that are very uncomfortable, that would be a possibility that there are black shows, and everything else above, would be good.

It hurt most of the time, take cheap new Chinese phone for $ 200 and move on.
A similar case was with htc hero

In principle, you can try to replace the touchscreen yourself, and not buy brand.

When the wife had the same problem, I was wondering to fix itself — and the experience and savings. Turned out $ 100. for touchscreen + 2 hours of personal time (including the search instructions).

In principle, the main thing all to do accurately. I'm after a replacement passed a couple of months — it's all right. But nothing put double-sided tape — was held to be so, and now a little more hard to press accounts.

As already mentioned above, a similar problem was on HTC Hero. I was the owner of this machine, and suffered with it. Eventually, the problem escalated into something like this:

In the end, I was helped by this article: habrahabr.ru/post/129098/
After warming up, the phone still lives.
I think you have a similar problem, and you should try it,
