3rd Party Hotspot Apps Disabled When Screen Turns Off - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Any third party hotspot app I use is being disabled when my screen turns off on the phone. I have tried everything I can thing of from optimizing battery settings to making these apps never sleep but each time the hotspot app disables until I turn the screen back on and/or unlock the phone. This does not happen on the phone's native hotspot app though. Any thoughts on this and how to fix this issue?

[Q] Wi-Fi Calling App and Tasker

I am trying to set up Wi-Fi Calling to automatically turn on WiFi when the application is loaded, and shut WiFi off when I exit, using Tasker.
I can get the WiFi to turn on when I start the app just fine. The problem I am having is with the exit task. I have the exit task set to kill the Wi-Fi Calling app and also to turn off Wifi. Problem is, neither happen when I exit the application and go back to the home screen.
I see that even when I exit the app and go to the home screen, Watchdog tells me that the app is still running in the foreground. Could this be the problem? Anyone have any ideas?
I am unable to kill the wifi calling app as well. It is always running.

Yeah, it seems the Wi-Fi Calling app is always running in the Foreground. Doesn't help with me setting up Tasker to shut off WiFi when I close the app.
There must be another way event that happens that can help me shut off WiFi when I leave Wi-Fi Calling...
you have to turn off wifi calling using the button at the bottom of the main screen in the app.

It is off. The app itself never closes. It is always running in the Foreground.
you can force close it in settings -> applications and then selecting it and clicking force close.

Tried this, it doesn't work
Well I have to ask stock rom? And rooted? If your rooted then try appfreezer for root. And just freeze the app when not using it and defrost it when needed

WLAN off when Screen off?

Hi,
I just discovered something strange: I use FolderSync to sync Music to my GN. I configured it to only sync when WLAN is available. When I sync and switch the screen of, then the Sync stops immediately and resumes when I switch the Screen back on. Is WLAN switched off when the screen is switched off? Did I miss some settings to configure that?
Thanks
May be related with some auto task killer or process killer like juice defender
Yes you missed some wifi settings. You can set there whether you want to turn off wifi with the screen, keep it always on or keep it always on while charging.
You can find it in:
Settings - wifi - ... - advanced
Thanks martan1981, but this is "always on" on my GN. So thats not the reason
Do you have any battery-saving apps like JuiceDefender or GreenPower installed? That could cause your data/wifi to turn off with the screen.
Or there could perhaps be a power-saving function built in to your ROM? I know AOKP has a Power Saver mode that could be enabled to turn data off with the screen.
wifi sleep policy should be set to never. But some people have a bug where this setting does not stick for some reason. You prob have this bug too.
I also have this problem how to fix it ?

Phone not sleeping

Does anyone has any idea why is it that if I were to use a 3rd party app to lock my phone, my phone would simply keep waking up but it would go back to sleep when I use my power button to lock my phone. Any help would be appreciate.
did you look into the settings from the third party App? is there a point that disabled the auto sleep function?

I've checked. I tried out a few apps that's in play store and all apps just keep waking up the device after I've locked. Do you have any idea on how to make them work?
Try this https://play.google.com/store/apps/details?id=com.katecca.screenofflock&feature=more_from_developer#?t=W251bGwsMSwxLDEwMiwiY29tLmthdGVjY2Euc2NyZWVub2ZmbG9jayJd and go to the configuration to set it up and you'll be good to go :good:

Screen Lock Key Pad Auto Show

Hi all,
I've got a really annoying feature on my screen lock where my keypad will auto-show and if I enter my PIN I'll be launched direct into the app at the time. I hate this feature and want to disable it, but I'm not sure which setting controls this. Did I say I absolutely hate this feature and it drives me nuts hence why I'm posting here.
Its not 100% clear what you mean.
Your lock screen activates and when you unlock it via pin you get put back into the app that was running before screen lock activated, when you'd prefer it to go back to the home screen?.
That is normal behaviour. There is no way to change it without causing an even bigger nuisance, which would be to kill all apps upon leaving them, which will make your phone run slow.
I could recommend an app by htc called "boost+" which can kill apps automatically if you apply the background optimizers to "always off" which will attempt to kill apps when you leave them. This is less intrusive than using developer settings to kill all apps. It may work, it may not.
Hi, thanks for replying.
Yeah sorry it is a little difficult to articulate this behavior.
So when I want to go back into my phone from the screen off / sleep state, I hit the power button to turn the screen on and wake the device up. When I do this the screen lock keypad opens and if I enter my pin I'll be taken into an application. Mind you this doesn't happen all the time. It generally happens when I've received a notification e.g. hangouts message, an sms, missed call notification, email and so on. I'm sure this behavior wasn't happening before. I can't remember if I changed a setting, or there's been an update to the lock screen from HTC. Either way I want to turn this feature off, I don't want the phone controlling me, I want to control the phone.

New Samsung settings and GPS

On android devices it was always possible to switch localisation services and GPS separately.
You could keep localisation services turned on (with wifi and phone) and turn off GPS to spare battery.
Now with android pie and new smasung settings it is all or nothing as there is onlys one setting :
I can turn on localisation and it turns on GPS
But if you turn it off, it disables everykind of localisation : GPS but also wiifi ...
Has anyone noticed this and is there a workaround ?
I'm not a fan of the always enabled GPS
I really do not like this at all. I have typically always kept GPS off as far back as Jellybean, favoring Locations battery saving mode, unless I needed navigation or something like that. GPS is power hungry and there's no reason to have to have it always enabled. I know Pie is supposed to help with battery usage and I honestly can't judge whether or not it really does yet as this is day two for me.
Pie is supposed to prevent apps from accessing sensors in the background but I've read that this doesn't apply to GPS so this whole thing is probably part of a marketing thing giving Google as well as app devs the ability to monetize ads based on specific location of us the users. Location is frequently wrong about where I am anyway, showing me a street over and even though I have WiFi and Bluetooth scanning enabled. As a result, my Safe Unlock no longer works when I'm home (only location I have enabled) which sucks. With Oreo I saw this somewhat often and only after I had been home for a while would the Safe Unlock work properly and I accepted this as a consequence of having Location in battery saving mode but now I'm not sure. I just no that with Pie, so far, Safe Unlock hasn't functioned once. My designated home WiFi that I'm on as I type should cause Safe Unlock to do it's thing but it's not. Maybe Location or Safe Unlock are broken. I have seen reports of both regarding Pie so I can't blame it in Samsung. I guess I'll have to try to figure out which of these features is broken.
I'm not sure if this is related to the Location issue but I also noticed that Samsung+ is not working for me. When I first tried to open it I got a notification that I need to have location enabled, I agreed (it was anyway), then I was shown a red screen with error or format codes that force closed faster than I could decipher it. This could be related or could have been broken in an update. Other than for ad purposes, and I don't recall seeing any other than Samsung ads in the Samsung app, I don't know why Samsung+ needs to access location services as it only works in the US and the network tells the app I'm in the US as well as the tower I'm accessing. I suppose it's another attempt to collect user info related to WiFi, Mac address and Bluetooth. I only got the "enable location" request the first couple of times I tried opening the app but the red error screen and FC both still occur. I tried to get a screenshot but I could only manage about half of the screen before it FC'd. I attached the partial pic. It's the bottom half of the screen. When it closes, the app window seems to slide up like when you close apps in the recents view. This brings up another complaint...Screenshot is slow to respond so events like this are next to impossible to capture. I'll have to get a camera out and try.

Yes I noticed this. I use 'Tasker' app as a workaround. I set Location Mode to High Accuracy when using Navigation apps, and set to Battery Saving after closing the Navigation app. You can also just create a widget on home screen to toggle Location Mode to High Accuracy or Battery Saving.
I confirmed this setting by using 'Power Toggles' app widget. When the GPS toggle in widget is highlighted, it means on High Accuracy mode, if not highlighted it's on Battery Saving mode.

I have yet to notice any adverse battery performance since I've been on pie and I've been on it since the start of the official betas. I was annoyed at first because I had always used battery save mode but really it's been a non issue for me.
