This issue is addressed in other threads here, but I cannot figure out how to use them. I have a Tracfone LG L41C. I hope some of the following is helpful: Android version 4.4.2, Baseband version M8610B-AAAANAZM-1.0.6048, Kernel version 3.4.0+, Build number KOT491.L41CV10a, Software version L41CV10a The message "unfortunately com.android.keyguard has stopped" appears from time to time when I turn on the phone. Initially I am unable to do anything. After a few minutes, I am able to turn the phone off (Power Off). Then, when I turn the phone back on, the message is not there, and the phone works fine. But the message will reappear a day or so later when turning the phone on. Its recurrence is unpredictable. I will REALLY appreciate any help! Thank you. Francis
