[Q] Screen will dim, but not turn off - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I searched this forum and the web, and found people with similar issues but no real solutions that worked for me.
No matter what my timeout is set to the screen will dim, but never turn off. I can't pin down an app that would cause this, and nothing special in the wakelocks. A reboot fixes it, but it comes back daily. I heard it might be lightflow, but i uninstalled it and no joy. Any thoughts?
Thanks

What rom is this doing it on? Surely not stock. I have seen 2 custom roms I know of that had that issue. Let me know...
thank you.

Im receiving my Vibrant on Monday... what can I do to limit the issues?

So im receiving my Vibrant on Monday, and from what I have read a lot of people seem to say that you should do a factory reset on it. Should I do this straight out of the box so I dont have to do it later on once everythings installed on it? And is there anything I can do to make the battery last a little longer? such as charge it up all the way, drain it completely, and charge it up again, and do this cycle three or four times or does it not help at all?
What I would like to know overall is what should I do straight out of the box to fix (if possible) the issues with the:
1. GPS (I understand the GPS and Compass issue are going to be fixed in the first OTA update, but until then can I do anything?)
2. Compass
3. Lag
4. Battery drain
5. Should I immediately do the factory reset, or wait and see if I have any issues?
From what I have read, it seems like 100% of people have issues with the phone, but maybe thats just because the people who dont have any issues with it are out enjoying the phone?
All help is extremely appreciated!!!!
C'mon, just enjoy the new phone.
jake...
exuse my most basic of basic questions. I am fairly new to the droid phones.
I see your question of problems with the Vibrant.
Well,you said GPS, and then compass
Well I know what GPS is, and I certainly know what a compass is.
HOWEVER, Not within the text of a phone. Is it simply a compass that is used by a GPS to function?? Again, excuse my bare bones knowledge guess. I should have PM'd you it is so silly. Maybe not
I would love to hear back from you. It sounds like you try to be one step ahead of the game. I would love it if you had the time to take to PM me...could you
My name is Eric (If I hear any more I will pass it on)

i really want to. but i have had so many issues with phones that this time I really want to know if there is anything I can do to prevent issues in the future.
The simplest guide to happiness with your new Vibrant
Reset it out of the box
Root
Install SetCPU
DONE
You should use a black or dark background to reduce drain on the battery and you also have to give the battery some time to adjust. GPS should be fine, but if it's not you should do a reboot first and you should try increasing accuracy before doing anything else. I have my Vibrant and I don't need any of the "fixes" to get a solid GPS lock. Solid enough for now until Samsung issues an update so we can lock onto more sats. I've seen the latest beta perform extremely well, locking on 6 sats at a time with 10Ft of accuracy (moving).
I just got my Vibrant today and was using the GPS just fine without a master reset or anything. Didn't even know there was an issue lol

great! thanks for help. the only issue is the rooting part... i can root a phone if i wanted to no problem, but the only issue i have with rooting is voiding my warranty-my MyTouch was replaced three times under warranty-if i need to replace this phone for any reason I would like to keep my warranty.
now i just have a question tho, how do i increase my GPS accuracy? all i see are threads on 'fixing' it.
thanks for the help,

Increasing the accuracy number (not "accuracy" in the literal sense) can be done by accessing the LBS (location based services) menu. It's under Application Settings from there. The code for getting there is in all of the fix threads. Just increase the stock 50 number to 100 and it should lock a bit easier.
Root, I don't believe there is a way to unroot back to stock. Not 100% sure on that so someone else can correct me. Root would only be useful for SetCPU, the ability to take screenshots and other minor things. No WiFi tether is reliably working right now which is bothersome and one of my biggest reasons for rooting.

That's one way to help, make sure all of your syncing is done at the longest intervals and things of that nature.. keep WiFi on for when the screen goes off you have WiFi.

Thanks for the great questions and posts in this thread. It helps.
Alec and Heygrl...I saw you ask about increasing the GPS accuracy of the Vibrant.
Then this code appeared. I have just never seen that. So I just type that in
My GPS is ok at best. If I use the code, and it was't quite necessary, it wouldn't hurt it, would it.
Thank you for your help, and your help throughout the thread

it would not hurt it. if it did, you could just change the setting back to 50.
Wow. You can unroot. There is a working tether option. Very likely you will not have any issues outof the box. Many of us have no issues with gps. You can do a factory wipe immediately after logging into the phone,i just don't see the point (seeing as it just came from the factory).
Strongly encourage you to read the sticky thread.
Also, not sure I see the reason for installing SetCPU, right now, as there are no kernels for overclocking.

[HELP] DHD wakes up by itself

Hey,
I have a major problem for a couple of weeks now. My phone just keeps waking up randomly and turns the screen on by itself. I have root and s-off and tried out a few roms. Sense Roms as well as MIUI roms... It does not make a difference at all, so I guess it can't be rom related. I have read a few more posts on the web of users having a similar problem but there was no solution given anywhere.
Also, my speaker automatically turns on when I receive or make a call. These two problems seem interconnected since there is at least one person on xda having exactly the same two issues...
Does anybody have an idea or a solution for this? I would be thankful for any kind of help! Thank you in advance!!!
I've a similar problem a bunch of months ago, my phone turn on automatically, without no logic. I've resolved the problem pulling out the battery for a night, after that the problem disappeared.
I hope that will help you to resolve your problem,
Rodomar705
Thanks, I will try that out tonight and report!
Ok, I tried it out last night, but it did not work
Does anybody have a different idea?

Did you check the date and time once you'd insert battery inside DHD? I think to solve the problem that way, you should leave DHD without battery until the internal battery will be totally discharged. It takes approx. 12-14 hours, and you can be sure only if turning on DHD you'll find time and date set to 12:00am, 1st jan 1980 (or something like that).
Yeah, it definately worked though, time was resetted as well. I turned it in today, hope to be able to pick it up next week. Before, I ran the Ruu to set it back to shipping condition... It still had the same error, so it is definately not rom related...
It is a huge drag without it... Already feeling uncomfortable ^^

Sorry mate!! Just wait for a week, ist not so long time, and you'll get back your phone as new as when you bought first time!! Hope this makes you feel a little bit of joy!!
Ok, I have gotten my phone back on thursday (after one week)...
SO far so good, everything worked again, they even set the proximity sensor right again... Then I rerooted it and put another MIUI on it...
On friday then, I put Vipermod back in and undervolted it by 50 mA... BOOM, the issue came back, I couldn't remove it, so I took the battery out and waited for 12 hours, as you suggested... and it worked... Issue was gone... Then I ran vipermod again and BOOM the issue was there again... It didn't even help to set the mA values back to normal, I had to reset it again by taking out the battery for 12 hours.
So my conclusion is that this issue is directly related to the actual USE (not just the installation) of vipermod... Can anyone confirm? Don't want to put out false information in the vipermod thread without having others to confirm...
need help also

If changing the ROM didn't help then it is an app issue. One of your apps is causing it. Time to look deeper
I have exactly the same issue! Also with the speaker sometimes. Really annoying. If an app is causing it, how can we find out which one? I'm using ARHD 6.1.0, but I've had the issue with older versions of the ROM too (with the same apps installed).

[App] Power Switch - screen off by closing your case

Guys, im the developer of Power Switch, an app that switches off your tablet's screen when you shut the case.
The main thread can be found here:
http://forum.xda-developers.com/showthread.php?t=1277712
Ive had reports of problems with the tab's light sensor, so would appreciate some debugging feedback.
You can use the lite version to test, it has all the features, but just wont save as much juice.
Thanks in advance. Feel free to reply here or in the main thread, i read both regularly!
Do you guys not have a light sensor or something?

Yes we do. Maybe if there was some incentive to be your testers, like a free full edition, you might get some to actually be your "guinea pigs"
It works, but it will be much better if we can have a locking sound...

Oh wow, thats a great idea, never thought of it... i will definitely add this in the next release.
Almost done!
Updated, added screen locking sound
I just ordered a case, so I will gladly test this out once I receive it.
Just to let you know, I did try the full version of your app, but ultimately refunded it. It's a great concept, but just didn't work well on my A500. I don't know if our light sensor sucks or what, but the app wasn't detecting the cover being closed.
Anyone else having problems? Problems not related to not reading the instructions?
I'll try again with the Lite version, and see if I can configure it better. I did read the instructions, maybe I was just too quick to dismiss it.
I tried this on my Acer and the Acer cover, but didnt seem to work. Also tried the lite version. I did play around with the settings abit but still nothing. Sorry
Hey I have a suggestion. I apologize if this is already a feature as I did not see it in the other thread. But if you're able to trigger screen locks and sounds and such, why not also add the ability to have it turn off/on wifi and/or 3g?
Interesting... i will look into it, thanks!
Any issues to report?

[Q] automatic brightness

Hey all, I searched but didn't come up with anything. I have an S4 Active and it is still on the AT&T bloatware. But its rooted and I used Titanium Backup to freeze a bunch of the AT&T bloat and Samsung stuff that I never use. I didn't freeze any google or com stuff, so I think it is unlikely I froze whatever controls it.
I only had the phone for a day before I did this, so it could be I never noticed it before and its done it since new.
But now, 5 days into owning the phone I notice that automatic brightness always sets the screen to the lowest brightness level, regardless of ambient light. I only noticed because I spent a lot of time in the sun Friday and Saturday and noticed I had issues seeing the screen until I turned off automatic brightness.
Is this a known bug with these? Is is possible I froze something that controls this?
OK, using the *#0*# dial screen shortcut I was able to verify that the light sensor is working as it should. I have tried rebooting, and factory reset isn't an option for me.
I've seen kernel functions mess up after rooting sometimes. Try flashing another kernel, maybe a custom kernel compatible for your phone.

Thanks for the feedback.
Not sure there is a custom kernel for this phone yet, as I'm not sure that the regular S4 kernels will work for it. But I'll look into it.

Try going back to stock unrooted firmware and see if the issue still persists. I think it might be tied to root coz some other features like allshare also break with root, and root works at the kernel level. You could check on the thread from where you got the rooting method, maybe others are having the same issue.

[Q] Red light - how widespread is this?

Hey everyone -
I originally posted about this in the Extreme Syndicate thread, but wanted to also ask here. I'm not sure if this is an issue wit my phone, the ROM, or the S5 in general. I'm on Extreme Syndicate L v2, and did a clean flash of it yesterday.
This morning, I noticed that placing the phone on it's back on a white surface while the screen is on caused a red light to appear. I think it's the heart rate sensor, but I'm not sure.
Is anyone else experiencing this? And could whatever-sensor-this-is-that-is-apparently-always-going be causing some people's battery drain on Lollipop?
Here's a short video.

This is not very wide spread from what i know, its not related to the ROM, i was stock unrooted android. Its an error in the Update process. Verizon is unable to fix it besides a wipe to the phone, Just factory reset the Phone and the red light will stop. Sorry I cant explain any more.

Are you saying you experienced this problem and have fixed it with a factory reset? Since I just wiped and re-set everything yesterday, I'd really only want to go this route if it's a proven fix... Thanks!

OK, I think I have it narrowed down to Google Fit. I went into the app's settings and told it to not monitor my activity. After a reset of the phone, the light isn't turning back on. I'm going to monitor it for the next hour or so to confirm that it's really off for good.
EDIT - The light is still staying off, so Google Fit appears to have been the culprit!

This Would make sense since when i would run S-health it would be off for as much as a day before returning. Google fit is a good idea, if that solves it try uninstalling the app and re installing I'm interested in know why a reset of my phone solved this.
Just as a quick heads up to anyone still watching this form, the red light error with google fit has been repaired. You can now use google fit properly and you will not get the heart rate monitor always being active.
