Mobile turning on but screen blank

last night I slept with music through Bluetooth headphones on mobile, in morning battery was drained. I charged it and turned on where it showed up few updates before turning mobile on, after 100% updates were done I turned mobile on and now NAVIGATION BAR KEEPS APPEARING DISAPPEARING CONTINUOSLY other than that notification bar shows notifications i can turn on camera lights and stuff but can't open application or take a photograph. After reset mobile was working but the second i turn off screen and turned it on again, blank with navigation bar acting up. PLEASE help i am really stressed. i love my huawei shotx mobile.
