OnePlus One has for long been affected by a spate of touchscreen issues, but the latest touchscreen bug appears to completely disable the phone.

Although OnePlus has rolled out around seven different bug-fixes for a succession of touchscreen problems on its flagship phone, Artem Russakovskii from Android Police has discovered a new bug that seems to shut off the touchscreen capability completely.

The new touchscreen disability bug has been reproduced on the smartphone used by Artem's wife, while a persistent bug has been confirmed on all phones running the Cyanogen OS 12 firmware version YNG1TAS2I3 .

Folks at Android Police have suggested that the complete touchscreen failure actually points to a faulty screen assembly or a bad digitizer, while the possibility of a manufacturing defect causing this widespread issue cannot be ruled out.

Nevertheless, Artem has explained in his latest Google+ post that the touchscreen disability issue cropped up a couple of times when his phone was placed outside on the table, in the heat of the sun (about 75F air temp).

However, affected OnePlus One users can try a complete restart of the phone via a hard reset (hold down the power button for about 15 seconds) to resolve this issue temporarily, until an official patch is rolled out.
