Cordoni and Curley,
Are you guys doing anything particular on the phone prior to emergency button not working again after soft reset fixing it? or do they just not work after being left unattended overnight?
I left mine idle for overnight and emergency button works is working fine. Just to note though, mine was non-rooted stock ROM with few apps installed before the DL09 update. (Launcher Pro, KaKaoTalk, Whatsapp, Shootme, Speedtest, Androidcentral & Angry Bird)
Maybe it a particular app that's causing this??
Could you post list of apps installed on your phone? I want to check what I should not install.
Thanks in advance!!
