How to prevent my S8 killing an app? - Samsung Galaxy S8 Questions and Answers

I currently use my S8 along with my Huawei watch 1 to start my PC via WOL. The process is that I use WearTasker on the watch, which triggers a tasker task, which in turn uses a plugin from the app Wake On Lan.
The problem is that, most times, nothing happens when I trigger the task from my watch. If, however, I go to my phone and start the Wake on Lan app - to make sure it's running - then the process works perfectly. Obviously, this defeats the point though.
I have both App Power Monitor and Power Saving Mode disabled in the S8 settings. Is there anything else I can do to make sure this app doesn't get killed and continues running in the background?

Add your app in to the "Unmonitored Apps" list under the battery screen (Scroll to the end of the screen in case you can't see).

Ok, done that - although I assumed that wasn't relevant since the app power monitor is off. I even had to enable it in order to add the app to the list - before, of course, disabling it again.

I initially thought that had fixed the problem, but the required app is still often not running.

Think it has something to do with having a lockscreen that has a pin/password, remove it and see if it fixes the issue

Interesting. I just tried it with the phone unlocked, but the WOL app not started (by me anyway - I assume it was running in the background or started by tasker) and it worked. Obviously, this isn't final proof, but it does lend significant strength to your theory...
As a father of young children - it's quite useful to be able to lock the phone. Is there a workaround for this behaviour?

Is this an app in the phone? If so you can prevent killing an app, by pressing recents button, 3 dot, lock apps. The app will stay in ram.

My S8 seems to just shut processes off when the screen is off. It's really annoying. No "OK Google" support, I can't get volume to work on my Chromecast except for maybe the first couple minutes the screen is off, then it works again when the screen is on, and simple app notifications like Domino's telling me my pizza status never works, even tho notifications are turned on.
It also likes to completely reset my games if I try to do something simple like minimizing it and doing a quick Google search. It seems like it just handles memory very poorly.

A few (software) issues with SGT 10.1...

1. There is no way to sync the clock to any internet time.
2. When the battery is fully charged, the screen turns on from standby (and stays on until the pre-set time-out). This is a problem if you leave you SGT plugged in at night. The screen will turn on in the middle of the night, and possible wake you up if you leave it by night table.
3. Bluetooth tethering for internet access does not work. Using my iPhone (with a legit tethering plan), I can connect to SGT via BT. The internet setting actually recognized BT was connected. A blue square icon was also shown in the lower right corner. However, no data was transferred.
4. Launcher crashes. Regularly about once every 1-2 day, Launcher crashes; i.e., pressed the 'house' icon then a blank screen was shown. Same problem with ADW launcher. The only solution was to reboot (like working with Windows computers, needs constant rebooting).

The only consistent crash/force close I have ever had is with the Google Listen app. I've never had a problem with the stock launcher, unless we count that annoying WiFi hang thing. But, that doesn't require a reboot either. Maybe you have defective hardware; can you return/exchange it for a new one?

1. If your tab is rooted there is. Get one of the ntp apps like ClockSync from the market.
2. No idea how to disable that. My phone does the same thing but the screen is so small that it didn't bother me much. The tablet is another thing, it lights up the whole room, really annoying.
3. Won't help you much when I tell you that bt tethering works great with my Galaxy S via the bt pan profile. All I have to do is enable bt, click the little wrench next to the Galaxy S and enable tethering. Maybe you have to enable something on your iPhone?
4. Never happened to me. You should try to set up your homescreens from scratch.
Btw. you might want to update your pc to something newer than win98 if you really believe in your comment about windows PCs.

Specific Tasker profile help

I figured this thread was a good place for this. If not, please re-direct me...
I'm looking to create Tasker profile "A" that stops Tasker profile "B" if; there is WiFi activity from app "A" in the past 5 minutes or less, and if there is a download in progress. Is this possible? And could I get some direction/ideas? Any help is appreciated!

What to you mean by "wifi activity"? Do you mean traffic throughput, on/off or connected/disconnected events?

Any activity other than updates, basically any active uses but not passive. I have a profile that shuts down the wifi after 5 minutes of the display being off but wanted to add exceptions such as I'm in the middle of a chat with a chat app that is always logged on so the wifi won't go off until a certain time after the last active wifi action from that specific chat app

Tasker lets you set up scripts to respond to states and events. You should be able to set a task to trigger on screen off and not a list of specific apps running. I do this with GPS on my phone so it only (and always) comes on when specific apps are running. In your case, something like "screen off and not chat running".
Tasker is pretty slick, but it's not always quick. I find it's fine for turning things off, but it sometimes is slow turning things on in a responsive manner. The GPS doesn't always get turned on in time for Maps not to complain, for example.
The problem with Tasker is that it can tell if an app is running in the foreground, but not whether it's passing traffic, at least in my experience. For the rudimentary wifi functions on my NOOKcolor, I found Green Power just as effective. It will shut down wifi after a period with no traffic, and periodically turn it back on to sync on a schedule, if you want. It is not sensitive to a specific app running, however.

Well if it can't detect certain traffic then I guess Green Power is my next shot. Thanks for the advice.
Tasker Read SMS
Hi. I installed Tasker and am trying to follow their walk throughs but the current version appears to be entirely different and I just can't figure out how do do any of this stuff. Could really use some help or an XML file. All I want to do is set up a profile that turns on bluetooth, gps fires up Google Maps and then starts listening for SMS text and read the SMS by voice if I get one.
All of their examples don't really jive with the way Tasker seems to work now.
Avatar, there are some obvious barriers I can see right off the bat, namely, no GPS or SIM card on the nook. Most of Tasker's functions (and wiki pages) relate to built in android functions so for example, instead of one action to enable GPS, it becomes a complicated series of actions such as enabling bluetooth, loading whichever bluetooth/gps app you use to connect, and simulating the correct sequence of button presses, waiting for it to connect, as well as dealing with it if it doesn't connect on the first try. It's very shonky and prone to failure compared to just enabling GPS on a device which has it.
I'd imagine the sms stuff is even more complex as you're already using a workaround to have that ability in the first place, so you'll have to work around that workaround, like the GPS. I bought a cheap phone to handle all that and its a much more straightforward and enjoyable car/tasker experience, minus the 7 inch screen.

Leaving app open, unlock phone, goes straight to home screen

Has anyone else had this happen? Happens quite often for me. I'll be playing a game at work, get up to do some work while leaving game open. Come back and unlock the phone and it's on home screen. Does the same thing while listening to Pandora.
I've never noticed that happening to me, I just tried to reproduce it with not luck. How are you unlocking the phone?
Either fingerprint or iris. It does it with both. I don't see it happening when turning phone off and on right away. Phone usually sits a few min before it does it.

Battery optimization setting probably. Try disabling optimization for an app that currently does it and see what happens
That didn't help
Couldn't replicate issue either. Let Rayman running and screen went off for about 5 mins. Unlocked with fingerprint and went directly to the game. I had power saving off and performance mode set to optimized.
OP do you also lose your place when it directs you to the home page? Or does it resume when you reopen the app?
It resumes when reopened.
Power saving off and performance mode set to optimized as well.
The one app where it does it almost every time is Star Wars: Galaxy of Hero's. Only other app I notice it once and while is Pandora.
Are you sure you aren't iris unlocking it without knowing you are? Sometimes mine unlocks almost instantly when i press the unlock button. Or when I turn my screen on to check the time.
Is "iris unlock when screen turns on" enabled?
Lock screen & security > iris scanner
I'm sure. Most of the time my phone is face down and I grab it by the side and put finger on scanner. Turned iris scanner off just to be sure and it's still doing it.
Also does it with line messanger...
I have this exact problem as well. Seems to happen rather randomly.
I sometimes see the app actually minimizing to the home screen when I unlock the phone, so it's probably not some background task killing it.
The app is only minimized, not killed.
I have this issue as well.
I think I found the problem. Uninstalled bxActions and as of the past 2 hours the problem is gone.
i have this issue but i don't have bxActions so i don't think that is the problem
Are any of you happening to use the long press home option, the one that bypasses the lock screen? Even though you may not be using the home button maybe the option is still affecting the apps that are open and thinks for some reason you're pushing on the home button.
It might be an app causing it. I still haven't had any issues since I uninstalled bxActions. If you don't have that installed it could be a different app causing it.
I was also having this issue. Stopped bxactions and the issue is gone. Started bxActions back up and issue came back.
Same problem here. On Verizon s8 and no bxaction installed. Very irritating!
Unrelated but another problem is when I change to aggressive wifi/cell handover in developer options it allways defaults back off after a reboot? Any ideas??

Random apps will think I have no network connection, when I obviously do... help!

Hey guys,
This problem has been going on for a week or two now. Phone worked great when I first got it, but something must have changed (newest Verizon update, perhaps?)
Let me preface this by saying I've seen this happen both on Wi-fi and 4G. When on Wi-fi, and it happens, I've tried turning Wi-fi off and still get the same errors.
The apps affected seem to be random. A couple days ago it was Google Maps, I was getting the "offline navigation" prompt. Today it was Chase (couldn't screenshot it), TeamViewer, IMDb and so on.
Here are some screenshots. Note the time in the pictures.
- First encountered the problem when opening TeamViewer.
- Did a Speedtest to confirm that yes, I'm really on 4G as the phone shows, and it's quite a stable and fast connection too.
- Let's try some more apps. Here's Target's Cartwheel
- Delta app? Same problem.
- TeamViewer Host app. Same problem as the client.
- IMDb. One more random one not working.
- Lastly, I went back to Pokémon Go to confirm I DO still have network connectivity (not sure why the screenshot got ghosted like that, but you can see I just redeemed items from a Pokéstop I was near with no errors)
So as you can see, the phone itself, as well as certain apps, work fine. But others don't. I tried turning airplane mode on and back off, disabling/enabling mobile networks, nothing works. The only thing I can do is reboot the phone.
Any ideas? This gets incredibly annoying as I can't seem to go a whole day without *some* app whining that it has no network access. Some apps work flawlessly every time (like the aforementioned Pokémon Go) but others don't.
By the way, that little screenshot button in the bottom left is from this neat app called Custom Navigation Bar. I'm pretty sure that has nothing to do with this problem, though, all it does is add buttons.

Do you have powersave mode on? I've had some problems with it enabled..
No I don't have power save mode on. Should I turn off the power monitoring of apps as well? Didn't think that mattered as long as power save mode was off.

I turned all the power saving stuff off and still have this happening. As in, I set it to not even monitor how much power each app is using.

Only able to download apps with battery saver enabled

Has anyone managed to permanently resolve this issue yet?

Sadly, I have just encountered this same problem - had my Yoga Book for a couple of weeks only, ran through the Android (version) update(s) and chucked a load of my usual apps on......and then this issue manifested
Having read around, seems that the only/most reliable 'fix' is the Battery Saver toggle, which - frankly - is not good enough. Whatever gets 'suppressed' with this mode is the key - something is not playing nice, and it is restricted to no effect when Battery Saver is on.....but what??

To me the behaviour seems like the update apps function has been disabled with the wrong battery saver state
What exactly happens? I have not got this issue but have seen similar issues on other android devices. If the OS thinks there is an app drawing over the screen. The Install button will show but do nothing when you press it. This is normal behaviour and part of the security for Android. Otherwise an app could draw over the install button with something else to trick you into pressing Install. Battery save is probably a red herring. It just happens to be killing the app with draw over other apps permissions. Look what apps have that permission and then force close one by one till the install works again. That will tell you which it is.
Hope that makes sense.
What happens for me, and I have only had my YogaBook for a few weeks, is that any app you try to update/install from the Play Store just doesn't actually start downloading: You are able to click on the 'Update' or 'Install' button, but then all that happens is that the horizontal progress bar appears, states 'Downloading' but never actually starts/progresses - you can leave this screen in place for several minutes/until patience expires(!)
Only solution I have found is, as per others, to turn on Batter Saver in the settings menu, and the same install/update/download then more or less instantly commences to actually happen!
Very bizarre......some sort of power saving setting in relation to the 'Download Manager' service, I reckon.......but nothing empirical to back this up. However, without fail, toggling the Battery Saver option on instantly allows the download et al to happen.

I noticed - I have not found a clear pattern - that sometimes, apps are installing or updating without the battery saver mode being on. Not always, and again, essentially always battery saver mode fixes this. It seems like they install on battery saver off more often when my VPN is active, but again, it isn't consistent.

Well as i type its back to installing as normal and the only thing i can think of is that my device previously went to zero charge. There was a google apps update too so not sure if its to do with that either.

Its certainly a good hypothesis, however, if i turn battery saver off, i am instantly again not able to download from the play store.
Ok so gets more curios - i installed CCleaner and opening the app makes downloads resume.
Ok so i think i have solved it. In my case it was outlook - i uninstalled it and now can download apps fine
Ok so scratch that, back to usual behaviour. Thought it was touchpal keyboard but no
I've never been able to find a direct cause as to why this happens. I've tried everything, including a full stock flash of the firmware. Even full stock, it worked fine for a while, but the issue eventually resurfaced.
I believe the service that's affected is D2dTransportService - com.google.android.gms.backup.component.D2dTransportService within Google Play Services. For some reason, it becomes disabled, and even forcing it to be enabled through a services manager app doesn't keep it active. I had a lot more insight into this a while back, but have since stopped caring as nothing worked and Lenovo isn't going to fix anything at this point.
No idea what's going on, but as others have said, the battery saver toggle is the only surefire 'fix' at this point. Given everything else seems to be working as expected, I've let it go and just accepted this as the new norm, ha.
I had kinda given up too, as the battery saver toggle was a hassle but worked. The past few days, it hasn't been working however. I spent most of the morning disabling various apps and services just to get back to being able to use the battery saver workaround. I'm so annoyed with lenovo and won't suggest their stuff anymore.
Ok so it gets more curious - the downloading works as expected when running in safe mode. The only thing that I can see that isn't running in the processes monitor is under 'Google services'. I have managed to get the downloading working as normal with a combination of disabling various processes but I can't replicate the steps each time.
right so i've narrowed it down to swiftkey keyboard. removing swiftkey and clearing the data of the download manager has fixed my downloading issue. back to normal!
Hmmm, I haven't installed Swiftkey (or any other 3rd party keyboard) on my YogaBook, and have tried clearing Download manager data/cache previously, along with all the other Google Play related things (services etc.)......and no joy, still only manage to download/update from Playstore when the Battery Saver is enabled.
Interestingly, however, the tablet will always identify/notify of available updates.....this means that the connectivity in Playstore works partially at all times, it is just the actual download element it fails on!!!!!

I'm bumping an old thread, but how do you get it in safe mode? I tried holding down the volume key on boot and it did not seem to work.
I thought at one point that, when I had SwiftKey installed, I started getting a lot more random reboots and also apps would not update even with battery saver. When I uninstalled it, apps started installing with battery saver again, but now I just re installed it, and they are still downloading with battery saver. So I still don't know, and now I'm not sure if it is causing the random reboots, either. Every once in a while I futz with it or else I just kind of let it be.

Try a "force stop" of the "Android Accessibility Suite" then start "Play Store" and see if updating now works.
