-===== Allow Locus to access GPS any time ===== +===== 1. Allow Locus Map to access GPS at any time ===== 
-The operating system must be set for Locus Map **NOT to switch GPS off in standby mode** (when the display goes off). Android 10 goes even a bit further: +The operating system must be set for Locus Map **NOT to switch GPS off in standby mode** (when the display goes off) - always select the **All the time** permission for Locus Map.

 +==== Android 11 and newer ==== 
 +The "all the time" permission is **not included in the system app permissions**. You can select only "while using this app" or "ask every time":\\ {{ :manual:faq:loc_permission01.png?nolink |}}\\ When you **launch Locus Map** and start a feature that runs in the background (voice navigation, track recording, live tracking...), Locus Map displays a compulsory warning:\\ {{ :manual:faq:loc_permission02.png?nolink |}}. Then you are prompted to **allow all-time access to the location** in the system settings:\\ {{ :manual:faq:loc_permission03.png?nolink |}}\\ {{ :manual:faq:loc_permission04.png?nolink |}}

 +This setting, however, is not permanent. **After not using the app for some time (e.g., three months), the "all-time" access permission is taken away** and you have to go through this procedure again.

-Here are a few device specific instructions:  +
-==== HTC ==== +
-//Standard/Extreme Power Saving Mode// - switch it OFF +
-<WRAP round tip 60%> +
-**See also https://dontkillmyapp.com/htc >>** +
-</WRAP> +
- +
-==== Samsung ==== +
- +
-  * **Android 6+** - settings > battery > //Power saving mode OFF// + battery use > "next" (three dots)  button in topbar > battery use optimization > click on "Apps are not optimized" and select "All apps" and here finally find Locus Map and switch the optimization OFF for it. +
-  * **Android 7** - Apps > ...(menu) Special Access > Optimize battery usage -> (drop down) All apps -> look for Locus and switch off switcher near it. +
-  * **Android 9** - Settings > Apps > 3-dot button top right > Special access > Optimise battery usage > down arrow > select all > scroll down and turn off the switch at Locus Map +

-==== Huawei/Honor ==== +
-There are several tips. Check out which one fits for your device: +
-  * Settings > Apps > Advanced > Ignore optimizations > All apps > disable optimizations for Locus Map +
-  * Settings > Apps > Settings button > Special access > Ignore optimizations > Locus Map Free/Pro > Allow +
-  * Settings > Battery > 'disable' Power saving mode, 'disable' Ultra power saving +
-  * Settings > Battery > Settings button > 'disable' close excessively power-intensive apps +
-  * Settings > Battery > Close apps after screen lock > 'disable' for Locus Map Free/Pro and all related add-ons, like e.g. [[manual:user_guide:geocaching:import|Geocaching4Locus]] +

-  * phone settings > battery > App launch > 'disable' automatic and keep all three 'manual' settings enabled +
-In Locus Map, better results are with disabled Settings > GPS > Google Services assisted location. +

-===== Battery optimization apps ===== + 
-There are also third-party apps that can maintain your battery optimization and may kill Locus or GPS unit. +
-==== Greenify ==== +
-Greenify has some special settings (labeled experimental), that enhance new Android 6 power-saving strategies. These power-saving strategies are labeled "shallow hibernation" and "aggressive doze". The "aggressive doze" mode contains also a white list of apps that are excluded from the mode and Locus is likely to be put here for the above-mentioned reasons. Unfortunately, this whitelisting does not work. After 5 minutes after your device enters doze mode Locus track recording is killed. Therefore, we recommend not to use this aggressive mode or the app as a whole.  +
-===== Universal solution? ===== +
-==== Memory Locker ====+
  
-Recently we discovered an application that can lock Locus (and other apps of your choice) in your device's RAM. It's called **Memory Locker** and is available at **[[https://play.google.com/store/apps/details?id=com.smartprojects.MemoryLocker|Google Play Store]]**. We have tested only a few devices with this app and it looks promising. However, as this is a third-party app, we have no responsibility for nor influence on the app performance. +===== 3. Turn OFF Google Services assisted location ===== 
-==== GPS Locker ==== +On some devices, this option causes the GPS for Locus Map running in the background to be killed. So, if you experience such behavior despite having performed the actions in steps 1 and 2, please do the following: 
-This app is able to lock the system's GPS ON so that the operating system can not kill it - we recommend in cases Locus loses GPS signal in standby mode and none of the previously mentioned methods helped. The app is available at **[[https://play.google.com/store/apps/details?id=com.silentlexx.gpslock|Google Play Store >>]]** +  * go to Locus Map settings > Gps&Sensors 
 +  * find Google services-assisted location and **TURN IT OFF**
