Yeah, I've noticed this some time ago... I'm sure I even filed a bug... But can't find it now. Don't have a good explanation either. It's either that CPU spikes after wake up (if you wait a few seconds before typing your passcode, can you still reproduce this?)... or some of the first input events after suspend get lost.
To try and track this down, we'd probably need to put some debugging in place to log input events as they come in, so that you can leave your device to suspend and grab some logs when you encounter the problem. ** Changed in: unity8 (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity8 in Ubuntu. https://bugs.launchpad.net/bugs/1389344 Title: Unlock screen is slow, drops passphrase key-presses Status in “unity8” package in Ubuntu: Triaged Bug description: Pretty much every time I try to unlock my phone the first time I get the pin wrong, the pin is missing a digit. I type pretty quickly, but this is only on the first time of unlocking after (for example) removing my phone from my pocket. If I get the code wrong, and wait a second then try again, I can type at the exact same speed or faster and it's fine. It's like one of my key-presses are dropped. It's frustrating as it happens every time I unlock my phone, unless I put a deliberate pause in between each digit. Happy to try and catch a video of it if nobody else can reproduce.
