S4 Mini screen lock query (sometimes screen stays on longer than it should)

[solquiff]

Hi, 2 things. Sometimes my S4 Mini lights up randomly when not in use (on lock screen). Today however something different happened. My phone is set to lock itself after 30 seconds. It normally goes black then locks so i have to put in my password again.Today I sent someone a whatsapp, put the phone down and about 4 mins later came back and the screen was still on in the whatsapp screen with all my convos. This has never happened before. Has this ever happened to anyone? What couldve caused this? Thanks in advance
