Re: Samsung galaxy s4 keeps dimming the screen for no reason. Any help?
My samsung s4 has also been dimming and brightening the screen randomly for many months now, despite no other apps controlling the brightness and regardless of whether the brightness setting is on "auto" or manual.
I can be reading a web page or using text or doing nothing (home screen) and the brightness suddenly fades as though the s4 is registering an auto brightness setting for a dark room or night conditions. Then, after anywhere from a minute or 2, up to about 15 minutes, it suddenly goes back to brightest setting, then dims the brightness a couple levels.
My s4 also immediately dims the screen when out in sunlight-extremely frustrating as i cannot use/see screen unless i shade the phone very well. And, no, just turning my back & creating shade w my body is not enough--it's more like i need area of shade at least 4x4 ft before any level of brightness will return. As soon I step back to sunlight, screen dims again as if it were night/low light conditions.
Also, i can never achieve the high brightness level that suddenly occurs when it appears the s4 is "self-correcting" the errant dimming, whether adjusting brightness manually or using the auto brightness feature.
I believe this started after an update. My s4 operates as if it has a mind of its own--or the brightness feature works almost the opposite way it should.
It seems obvious to me that owning a model more than 1 year old is problematic. It's unfortunate because there are a significant number of people (including myself) who wait until their 2 yr upgrades w service provider is avail to get a new phone. Not everyone can afford to buy a new phone every year, nor should they have to even if affordability is not an issue. Yes, some carriers are no longer doing the 2 yr upgrade, but plenty still have it avail--(grandfathered) one last time.
