    Default Samsung Galaxy S5 Display Turns on Randomly When Locked

    I have had my S5 since the week it came out and I am now having a problem when the display will just randomly turn on when the screen is locked. I do not have it in my pocket, it sits out on a desk all day and since I am not around it every second of the day it drains my battery. The phone will be locked, sitting out on the table and the screen will turn on and ask for my alternative password. I use the fingerprint scanner to unlock my phone and have never had to use this password before. To turn the screen off I have to hit the button on the side to force it off. If I walk away and come back a few minutes later the screen will be back on asking for the alternative password. Does anyone know what is causing this or how to make it stop, my battery doesn't last through the day even when I'm not using it???

    I am not sure what is wrong. I would try clearing the system cache in recovery. Hopefully that will help.

    Follow the steps for the S3.

    I'm having the exact same issue...have had my S5 for several months and then just within the last few days the screen keeps turning on while sitting on my desk (like I'm getting a notification). Tried clearing the system cache, but no joy.

    My phone just started this today and I have CM11 on it but I've had a custom ROM for the past month so I don't think would be it. Idk if anyone finds a solution please post to this thread!!

    I had the same problem with my s5. My issue was the headphone jack. For some reason it kept detecting headphones and turning on the screen in response. I fixed my issue but actually putting headphone in the aux jack and removing it. As of a few days, the issue has stopped.
