Overview
This document provides recommended settings and best practices for users running the SNAPmobile application on an Android smart device. Because mobile devices manage battery, notifications, network access, and background applications aggressively, the correct settings are important to ensure reliable ringing, audio quality, and call stability.
General Best Practices for Android Users
Keep the Application Updated
Users should always keep the SNAPmobile application updated to the latest version available in the Google Play Store.
Application updates may include important fixes for:
Call ringing
Push notifications
Audio quality
Bluetooth behavior
Login stability
Messaging
Compatibility with newer mobile operating systems
Keep the Mobile Operating System Updated
Users should also keep their Android operating system updated.
Recommended:
Android: Use a recent Android version supported by the device manufacturer.
Older operating systems may create issues with notifications, background calling, Bluetooth audio, and app stability.
Allow All Required Permissions
SNAPmobile should be allowed to access:
Microphone
Contacts, if contact integration is required
Notifications
Bluetooth, if using Bluetooth audio devices
Cellular data
Background activity, where available
Without these permissions, the app may not ring, may not access audio, or may not work correctly in the background.
Recommended Android Settings
Notifications
Go to:
Settings
→ Apps
→ SNAPmobile
→ Notifications
Recommended settings:
Allow Notifications: ON
Calls: ON
Messages: ON
Sound: ON
Pop-up notifications: ON, if available
Lock screen notifications: ON
Notification categories: Review and enable all relevant categories
If Android notification categories are available, make sure incoming call notifications are enabled and not set to silent.
Battery Optimization
Android often restricts apps in the background to save battery. This can affect incoming calls.
Go to:
Settings
→ Apps
→ SNAPmobile
→ Battery
Recommended:
Set battery usage to Unrestricted, Not Optimized, or Allow Background Activity.
Do not place SNAPmobile in Sleeping Apps or Deep Sleeping Apps.
Disable any manufacturer-specific battery restriction for SNAPmobile.
On Samsung devices, also check:
Settings
→ Battery
→ Background Usage Limits
Recommended:
Remove SNAPmobile from Sleeping Apps.
Remove SNAPmobile from Deep Sleeping Apps.
Add SNAPmobile to Never Sleeping Apps, if available.
This is one of the most important settings for Android users.
Microphone Permission
Go to:
Settings
→ Apps
→ SNAPmobile
→ Permissions
→ Microphone
Recommended:
Microphone: Allow while using the app
Without microphone permission, call audio will not work correctly.
Phone Permission
Go to:
Settings
→ Apps
→ SNAPmobile
→ Permissions

Recommended:

This may be required for call handling and integration with the device.
Contacts Permission
Go to:
Settings
→ Apps
→ SNAPmobile
→ Permissions
→ Contacts
Recommended:
Contacts: Allow, if the user wants to access mobile contacts from SNAPmobile.
If the user does not need contact integration, this can be left disabled.
Mobile Data and Background Data
Go to:
Settings
→ Apps
→ SNAPmobile
→ Mobile Data
Recommended:
Allow background data usage: ON
Allow data usage while Data Saver is on: ON, if available
Unrestricted data usage: ON, if available
If mobile data is restricted, SNAPmobile may not receive calls when the user is away from Wi-Fi.
Data Saver
Go to:
Settings
→ Network & Internet
→ Data Saver
Recommended:
Data Saver: OFF during business hours
Or: Allow SNAPmobile to use unrestricted data while Data Saver is enabled.
Do Not Disturb
Android Do Not Disturb can silence SNAPmobile notifications.
Go to:
Settings
→ Sound & Vibration
→ Do Not Disturb
Recommended:
Make sure Do Not Disturb is not active during business hours.
Allow SNAPmobile notifications as an exception, if available.
Review automatic schedules.
App Auto-Start / Background Launch
Some Android manufacturers include additional app management controls. Look for settings such as:
Auto-start
Background launch
App launch management
Protected apps
Battery manager
Adaptive battery
Recommended:
Allow SNAPmobile to start automatically.
Allow SNAPmobile to run in the background.
Disable aggressive battery restrictions for SNAPmobile.
This is especially important on devices from Samsung, Huawei, Xiaomi, Oppo, OnePlus, and similar manufacturers.
