The OnePlus One is no stranger to touchscreen issues. Problems with inaccurate taps have been affecting some users almost since the initial release a year ago - the company has issuednolessthansevendifferent"fixes" for the problem across CyanogenMod S and Oxygen OS. The latest problem is easily the most glaring, and it's been documented by our own fearless leader Artem Russakovskii. Basically, the entire touchscreen seems to be shutting off randomly.
Artem isn't the only one experiencing this: his wife had the same issue shortly beforehand on her own OnePlus One. If you're wondering, he's running firmware version YNG1TAS2I3, and he had been using the phone outside (but not in any particularly intense heat) before seeing the problem crop up.
At this point, the words "OnePlus One" and "touchscreen issues" seem to be almost synonymous on our site. You can't mention one without the other being brought up after all the annoyed reports from users, promises of solutions, so-called "fixes" being rolled out, only to be followed by an emerging set of new issues and vows by OnePlus like a snake that sheds its skin only to regrow another one. But that may be over. And I use italics here, because if you read the comments on OnePlus' forum and Reddit, you'd think a miracle just happened and we're about to canonize Steve Kondik while he's still alive.
