Neil.Jain93 , Jun 12, 2018 : Hello, Needed some help as my phone is acting weird. So on Sunday 10-08-18 my phone was on table when it suddenly Unlocked and I could see the Volume increasing and decreasing (all this while I have not touched the button of my phone) and then when I try to lock my phone by pressing the lock/power key it won't lock. I tried to restart the device by pressing the Power key but it by default rebooted to the BIOS and gave me option on the top of my Display Power On / Reboot / Power off / factory reset and had few more option listed below these option and the last option mentioned device status: Locked in red colour. we tried to restart the devices but the buttons were not functioning and after trying 3 to 4 times by hold the volume rocker and power button we were able to boot back to normal, But today 12-08-18 I'm facing similar issue that I cannot lock my device. Can someone help me out?
