Galaxy S5: Auto Screen Brightness & Heartbeat Not Working

[SlackBlade]

I have two issues that I think may be related. Was wondering if anyone else had an issues like this. I have a Sprint S5, black.

1) When I turn in auto screen brightness in normal room brightness, the screen is very dim. I turn the range all the way up and turn it back on, and it is still dim. It does work in bright light, but not normal.

2) When trying to get heartbeats on the back of the phone on the led light, it can never read it. I know I have been dead to some people, but I know I have a heart (and a beat). I couldn't tell if there is a film on the sensor (like the camera lens). I tried to take it off, but don't believe there is film on it. I have tried to take it multiple times with multiple fingers, and it never reads. I have followed the instructions and diagrams it shows when it cannot read, and nothing.

Anyone else have similar issues?

I have had exact same issue with heartate scanner. My husband and sister both got it to register on their first try though so clearly it functions. Guess I have to keep practicing. I actually just got it to work twice with finger sideways on it pushing very slightly. I have my finger orientated differently than the picture shows and it's the only way I can get it to work.

After trying for the 20th time, I got the Heartbeat to read. Of course it works after I finally decided to post after sleeping on the thought.

I got it to work by not centering my finger on the opening, but to the right were the center is. To further explain, I centered the middle of my finger on the right side of the sensor, and not one the center of the opening. It immediately read three times in a row.

Hope this helps others.

Still having problems with 1) Auto brightness.

I have the same auto brightness problem with an S5 in the UK - and Samsung support have been of little use, just saying factory reset the phone and try again.

I find that if I have the dim screen option on under power saving mode, I have that same problem.

You need to put NO pressure on it. Just rest your finger so the edges of the lens are touching the pad of your finger. I've never had an issue so far.

No problems with the heart rate monitor either, but I never applied any pressure. As for the auto brightness, I notice a dim but it doesn't bother me as I assume this is normal. I'd disable it and manually set it as auto brightness sets the screen depending on the brightness environment. It's actually more useful in bright sunlight

Makes perfect sense thank you !
