STR: - lock the phone - turn on the phone - put the phone in landscape mode * wait until the screen rotate - try to press and slide the button toward the open lock. Seen: - No touch event seems to be considered. Expected: - unlock the phone as in portrait.

To my knowledge, the lockscreen should never be in landscape mode. What where the app you used before locking the phone? Also, how old is your build? Could you run this script[1], so we could have this info? [1] https://github.com/Mozilla-TWQA/B2G-flash-tool/blob/master/check_versions.py

I found out that's a recent regression. It's not possible to put the lockscreen in build [1] but it is in build [2]. STR 1. Open the Browser app 2. Flip down the device 3. lock the phone 4. turn on the phone 5. put the phone in landscape mode 6. wait until the screen rotate Repro frequency: 5/5 [1] Build ID 20150816150205 Gaia Revision 47c91ffe7f500ca1aaa60de0aabf4d2429120733 Gaia Date 2015-08-14 18:55:02 Gecko Revision https://hg.mozilla.org/mozilla-central/rev/0876695d1abdeb363a780bda8b6cc84f20ba51c9 Gecko Version 43.0a1 Device Name flame Firmware(Release) 4.4.2 Firmware(Incremental) eng.cltbld.20150816.182145 Firmware Date Sun Aug 16 18:21:56 EDT 2015 Bootloader L1TC000118D0 [2] Build ID 20150820150207 Gaia Revision c6705f739fb605031eb2a0b943ba55c64bee5a03 Gaia Date 2015-08-20 14:36:40 Gecko Revision https://hg.mozilla.org/mozilla-central/rev/095988abdc560bf8ba07a94a425c6922a3e9bfd6 Gecko Version 43.0a1 Device Name flame Firmware(Release) 4.4.2 Firmware(Incremental) eng.cltbld.20150820.183055 Firmware Date Thu Aug 20 18:31:07 EDT 2015 Bootloader L1TC000118D0
