Tab S 8.4 ramdomly sleeps?? - Galaxy Tab S Q&A, Help & Troubleshooting

Searched the forum and did some google searches but only came up with one thread somewhere else that never went anywhere. This may be glitchy apps (although I have both on my Droid Maxx as well with no issues) but I thought I'd ask anyway.
So the problem is the tablet(SM-T700, Android 5.02) will seemingly go to sleep while actively using an app (so far it's common in 8 Ball Pool and has also happened during Beach Buggy). I don't know if it's app related or a setting somewhere. I have power saving modes turned off (as well as auto screen brightness). Anyone else experience this?

Well it may be a combination of the app not telling the screen to stay on (twitch app had this issue for about 3 days then it got an update) any you having the auto screen off timer set too short.
The permission used is under others and is called quite simply (prevent tablet sleeping). With out that mode set if you do not touch the screen in (insert screen shutoff timer length here) the tablet will turn the screen off to save power.

Thanks, I'll check that out. I'm going to run a few more apps and see if it happens with them also.

[Q] Syndicate FroZen 1.0.3 settings don't save.

Hey guys, I have been using Syndicate Twilight Zone Frozen 1.0.3 for about a month now...
I love it, only a few quirks...
Screen brightness settings seem to not save. I always set my phone to the darkest setting, I disable auto adjust brightness, I also disable powersaving mode that allows the phone to adjust brightness based on surrounding ambient light...
However, after charging phone or (maybe its a game that changes my settings...just thought of this, we have angry birds on there) or basically just using the phone, I will go check it later, and the screen will be brighter and the I have to change all the settings again...
Related, also, I use the option under development to keep the screen always on while charging (unless I manually turn screen off) this gets unchecked all the time as well, and I will have my phone sitting there, and the screen will go dark on me...
Anyone else have this issue? (I note it may be a game, but I actually didn't install angry birds until like a week ago, and I recall this happening before I put angry birds on my phone)
Thanks.
Oh one more thing, Asphalt doesn't seem to work on this rom either, only reason I have that game or want it back is my kid was playing with my phone and bought the game from sprint (little brat)... Anyways, that is 2ndary to my main issue.
Thanks again everyone here for all this great work.
Bump...only bumping this once.
Thanks guys.
Upgrade to Frozen 1.1.0
I have been running it since the day after it came out and am having no issues with it.

ROM/kernel Not Playing Nicely- No "Deep sleep" & "Titanium Backup" & More

ROM/kernel Not Playing Nicely- No "Deep sleep" & "Titanium Backup" & More
I'm on Juggernaut v4.1 & Synergy kernel v.10 with an undervolt at all times in different profile modes.
I noticed this a few days ago, I'll go in order of the "symptoms" my SGS2 T-989 experienced:
1. Random shut downs which won't allow me to reboot without taking the battery out or long-pressing the power button.
2. Titanium backup lags like CRAZY. If I go to my app list, it freezes while I'm scrolling, with the only solution of a Force Close. Batch backup freezes at any random point and doesn't ever pick back up. Even a force close/reboot doesn't make any difference.
3. If I get a text message or notification, the screen doesn't turn off (only stays at the lockscreen). At one point everything worked okay.
4. My phone doesn't "deep sleep" when my screen is off. I know for a fact that this is a problem because I use CPU Spy very frequently to check up on what states my processor runs. Deep Sleep has been inactive/never used in the last few days since I reset my CPU Spy timers once I suspected a flaw.
I suspect that all of the above symptoms are all propagated by the same issue.
As a general statement, I could just format/reFlash my ROM/kernel but I would like to backup my stuff beforehand. I had this problem earlier when I first got my SGS2 but had nothing on my phone at the time so I never bothered posting about it. I'm hoping it isn't just my phone and someone has some sort of solution.
Thanks for peaking and helping out.

Why not just try a different kernel? You can flash a different kernel without loosing anything(if all goes well) ... I use the Faux kernel, and I have no sleep or standby issues ... and have used it with Jug

NY Times

Anyone notice problems with the NY Times app recently? I noticed some high network activity out of my Note Pro over the last few days, and dug into it last night. Turned out, my tablet never went to deep sleep, and looking at battery usage, the NY Times app was behind only the OS and System.
I can't uninstall the NY Times, but I can revert to the factory image, and that seems to have put a halt to the network activity, and also the tablet is now going into deep sleep again. So it looks like it was an app update, somewhere along the way?
What's deep sleep as opposed to sleep as opposed to going into airplane mode?? Your posting about the ny times and sleep is difficult to understand.

Not difficult to understand at all, this is apparently a wake lock issue with the application.
Tapping the power button to turn off the screen puts the device in sleep mode but CPU speed still varies as background activity continues. Application processes can place wake locks on the CPU to keep it from going into deep sleep which is the lowest power consumption setting. A device that never goes into deep sleep will experience higher battery drain with the screen off for extended periods than one that does go into deep sleep. Sleep has nothing to do with airplane mode, which turns off all radios and has no direct impact on CPU.
First thing I would try with the NY Times app is turn off all notifications for it. Personally I don't use it and have it frozen so I can't verify the wake lock issue on my device.

Much better explanation than I could have given, thanks! So wish I could root my tablet (a Verizon...), feel like I'm trying to debug things with both hands tied behind my back!
So far, the NYT problem hasn't come back - can't freeze or uninstall it without root, but have removed it from Magazine UI and basically backed out all updates by restoring it to its factory image and clearing its data. BTW, it was set to only get updates every 4 hours. Obviously it had a different idea.
Yeah I hate it when apps get like that.
It's times like that where I'll use Greenify sparingly to push the misbehaving app into hibernation. Otherwise I'll just let android do it's thing.
A few days ago, I noticed the NY Times app only it's you view 10 articles for free every month. I was going to say, why not trash that garbage? It requires root, though, since it's actually a system app. That is just profoundly stupid.
At least Samsung didn't pick CNN as it's news app, amirite?

How Can You Disable Screen Dimming?

Is there a way to keep the screen from dimming after a period of time? I set it to never turn the screen off while charging, but it still dims while the music app is up when it's charging in the car which is annoying. I can't find the setting anywhere in LG's settings or in tweaksbox.
I tried Lux as others have suggested but it still dims in my truck. Very annoying.

My screen doesn't dim ... did you turn off Auto brightness?
What would cause it to dim by itself? I only run at 61% brightness so maybe I haven't experienced this yet
My auto brightness is off and it still dims. Lux auto is on or off and it still dims.

Yup, I always have auto brightness off. It just dims after a minute or so of no input - which happens while I'm driving. I always keep it at 100% unless I'm in the dark which may be why you haven't noticed it - the screen may dim to around 60% anyways. I find it weird that you can't adjust how long it waits to dim, or turn that feature off. I'm guessing this is part of LG trying to help with battery life.

Hmm weird. I wonder if this is the overheating issue I read about

I've only ran into that a couple times and the screen dimmed to 90-95% and I had to manually turn it back up. This is different where it goes bright again as soon as I touch the screen and the dimming is much darker than 90% - more around the 50% ballpark.
Wow, yeah that sounds extreme...
I know it's a pain, but have you considered doing a hard reset to see if it is indeed setting/software related?
If the OP was referring to the "Screen brightness lowered due to high temperature" message.
Go into the hidden menu by typing 3845#*855# (replace 855 with your devices model number, mine is a D855).
Then scroll down to Thermal Daemon Mitigation OFF and make sure it is enabled (on).
Reboot the device and you can now force maximum brightness all the time.

I actually had to get a second phone a week ago because I cracked my screen (a few hours before my protector came in the mail). At least it was early enough that I got a brand new phone through insurance instead of refurbished, but both phones do it. Could be a Sprint vs Verizon difference - Verizon likes to go crazy with phone mods lol. Though I don't normally run into it with normal usage - only when the screen is set to stay on while charging through the developer option and I'm driving with music.
Mine does that. Sprint phone, happens after a minute of no input, including when the screen is set to stay always on. However, I notice this doesn't happen when running Maps.
I've already gone through two phones, same on both.

There are certain apps - and Maps is definitely one - which will not allow the screen to dim or the device to sleep. (YouTube is another for example, also iHeartRadio, etc.) Really the best thing to do is mod using something like Tasker or Stay Alive! as I mentioned in an earlier post for specific apps. I use mine for the Music app since typically I've got mine on the car charger and dash mount and it makes no sense to go through a whole screen unlocking routine to fully operate music after a while.

Disable Screen Wake

A quick search turns up the same question for different devices. Most the answers dealt with rooted devices, mine is not. The screen will fire up on its own, randomly. I do have Greenify and grant certain apps to close once the screen is off. That doesn't appear to be my issue. No apps are running (well, no apps that aren't system). It's a strange occurrence that drains battery because I have screen off set to 10 minutes. How do I determine what is triggering wakes? Anybody else notice this, I can't be the only one? Samsung issue or Android O/S issue?
My fiance has the same issue, mine doesn't. If you move the phone it wakes.
