Appium tests: Cannot click on some elements

Appium fails to click on some elements of native UI.

For example, it incorrectly clicks "Gallery" menu element in camera plugin tests on Android 5.0 or it cannot click at all on the first contact in contacts list on iOS 8.1

The workaround is simple and quite weird: we should select the element 3 times in a row, then it works.

The timeout before element selection doesn't work.
