Hello,
can someone confirm, that the following is a general problem?
Enable Energy Saving (Via [quick] options)
Turn on Google Maps
Start Navigation to X
Wait for GPS Fix (GPS Symbol in statusbar stops flashing)
Turn screen off
Wait a few seconds
turn Screen back on and quickly watch for the gps icon
On my just-resetted M8 (6.0 Sense 7 - international - full stock) it lost GPS Fix while the screen was off.
As a check, I did the same with Power Saver disabled. Then it kept the GPS fix even when the screen was off.
Now, why is this important:
When using my M8 in my car, Android Auto will turn the screen off when connected to the entertainment system. So when Power Saver is enabled , navigation in Android Auto is broken because it will loose GPS Fix as soon the screen turns off.
Again, with Power Saver disabled navigation and Maps are working as intended.
Does anyone got a workaround ?
tl;dr: Power Saver breaks GPS when screen off

I've had this issue with five different ROMs including the stock HTC ROM. It doesn't do it when the ROM is flashed freshly but starts within an hour or so, regardless of whether I load any other software on.
Here's exactly what happens. It doesn't matter if the unit is in standby or if the proximity sensor is activated. (On a phone call with phone by head - backlight is disabled.)
When the backlight is off and is activated by either pressing the power button or moving the phone away from the head, the backlight comes on dim, then goes off, then turns back on at regular brightness. The delay between activating the backlight and reaching regular brightness is around one second.
What is going on? This is really annoying. If I'm on a call and want to mute the mic, I take the phone away and "flash, flash, mute". Then I want to unmute and the same thing.
I don't have any software on the phone right now that most of the rest of you don't have. I've got:
AT&T keyboard fix
Dusk lockscreen
PHM Regedit
Safe Inbox Extender
Clock flip disable
1% battery driver
Theme pack for 1% battery icons
I've reflashed and installed none of this software and the issue doesn't occur. Without installing any software, the issue recurs within a day. (Usually within an hour)
Any help or insight would be appreciated.
Since we need to have the screen turned on to keep wifi/gps etc. running, and there are a few apps that would ideally run in the background with the screen off; to save battery power (and burn in?) it would be nice to have the AMOLED screen display just a black image.
Is there any app out there that just displays a black screen and maybe ignores all but a specific input?
At the moment I just zoom into a black image in the browser, but I can't put the phone in my pocket like that.
(I tried searching for this, but it was beyond my google-fu.)
You dont have to keep the screen on to run either my gps is always on and it neva disconnects also ive spent many nights going to sleep leaving my wifi connected and its neva disconnected either
Yup. If you haven't set WiFi to switch off after 15mins, it should carry on running.
By doing what you proposed, you'll decrease battery life drastically as you'd effectively be disabling the chips sleep mode by keeping it running 100%. With that, only the screen switches off and everything else including Android keeps running. Any application holding a partial awake lock can achieve this.
Lock delay; an app to control the default screen-lock options allows this.
For instance, if you set the initial screen timeout to 2 minutes but standby/lock to 10 minutes in the settings, the screen will switch off after 2mins idling, but the rest of the phone will still be running incl. WiFi/GPS. You can enable a lock/pattern or no lock at all where you press any key including menu/trackpad and it'll come back on in the same place you left it, without any lock. If the phone idles for 10mins, it'll activate the screen lock and place the phone in the standard sleep mode. The max delay you can set the latter to is 24 hours.
I wouldn't advise avoiding the sleep mode unless required in specific circumstances. Battery loss will be drastic; I found out unintentionally when activating this option at the beginning.

Thanks th3, that should do what I want. I don't intend to leave it unattended, it's just for when don't need the screen on while an app is doing something.
Hi,
plz help me...
My phone is LG G3 D855 with Android 6,
When the battery power shortage warning message appears on the screen,
Automatically turn On GPS location phones,
How to turn on automatic navigation GPS prevent it?
Thanks
Always-on is set to "on", so there should be a clock showing when it's dark, but there is not (no clock showing). Still activates when I touch it or press the button. Restarting, or power-off then on doesn't work. Changing watch faces doesn't work. I'm wondering if battery-saver is somehow stuck on, but can't figure out where to access that setting manually. Any ideas?? Thank you!
it's a bug. Let it go to under 15% battery and then turn it off.
I would like to turn the torch on when the phone is shaken. This works, with event" motion left-right, action: toggle torch.
The problem is it does not always work when the screen is off. It sometimes works, which is really annoying. I've turned off battery optimization already for Tasker.
