Android back node has problems on cell phones with one button.

Android back node has a problems on cell phones with one button. Meizu m3 mini back button works only after 4-6 attempts on press. Works without problems on phones with 3 buttons.

Please fix this error I waiting almost a year to get things done.

That phone…does it have touch sensitive buttons for Back and Recents? Or only in software? Can you show a screenshot? I haven’t heard of this issue with Samsungs and they only have 1 “physical” button in the center. Have you tested other devices with only one button to confirm that is the significant factor, or is the Meizu M3 the only phone you’ve seen this issue on so far?
