swipe to unlock does not always work

When my new z3 is locked, I frequently have trouble swiping to unlock the phone. When I try to swipe, I get the nice psychedelic particle trail showing the swipe, but often the phone does not unlock. It can take 3 or 4 attempts to get the darn thing to unlock. It is bad enough that I worry that the phone will simply not unlock no matter how many attempts. Very very irritating. I write firmware for a living. This is a serious bug.

And when I google the problem, I found other users experiencing the same problem.

See http://forum.xda-developers.com/z3-compact/help/swipe-issues-t2888154 .

Is there some way to get this problem in the Sony bug reporting system? When is Sony going to fix this?

I haven't been able to replicate this

@elliotl

Do you have a protective case and/or film on your phone?

I have a protective case, but no film over the front screen. It may just be some phones, but I am not the only one seeing this. The post from 'Caine' that I referenced describes the exact same problem. I can see particles trailing my finger, but the phone does not unlock.

It would be better for everyone if you could easily reproduce this bug. Even if you cannot see it, the bug should be submitted to the people maintaining the software for the phone. The fact that it may be difficult to reproduce makes the bug arguably more serious, because it will probably be harder to fix.

On my phone, this bug is easy to see. Happens about half the time. Just a few minutes ago, it took 5 long swipes to unlock the phone.

Boot on safe mode for an hour or so, lock and unlock the phone over and over until you can recreate the issue, if you can't then it's another app creating this issue.

Do you have any antivirus, taskillers, third party lock screen, third party home launcher?

I rebooted to safe mode. Phone behaves exactly the same. Took 4 swipes to unlock the phone the first time.

Very very little is installed on this phone. Yahoo mail client. First Tech Credit union app. Probably one of the cleanest phones around.

You could repair the phone with PCC and report back

PC Companion (PCC)

Bridge (for Mac)
