Answer 1

Huawei, Vivo, Oppo and Xiaomi restrict background services. Please also take a look at here

edit: In these brands, because of lots of customization, all services are restricted by default. either you must disable background restrictions for your app via settings or you can prompt to the user by firing an intent. Unfortunately, the path to the Background Restriction settings is different in each Operating System.

private static final Intent[] POWERMANAGER_INTENTS = {
new Intent().setComponent(new ComponentName("com.miui.securitycenter", "com.miui.permcenter.autostart.AutoStartManagementActivity")),
new Intent().setComponent(new ComponentName("com.letv.android.letvsafe", "com.letv.android.letvsafe.AutobootManageActivity")),
new Intent().setComponent(new ComponentName("com.huawei.systemmanager", "com.huawei.systemmanager.startupmgr.ui.StartupNormalAppListActivity")),
new Intent().setComponent(new ComponentName("com.huawei.systemmanager", "com.huawei.systemmanager.optimize.process.ProtectActivity")),
new Intent().setComponent(new ComponentName("com.huawei.systemmanager", "com.huawei.systemmanager.appcontrol.activity.StartupAppControlActivity")),
new Intent().setComponent(new ComponentName("com.coloros.safecenter", "com.coloros.safecenter.permission.startup.StartupAppListActivity")),
new Intent().setComponent(new ComponentName("com.coloros.safecenter", "com.coloros.safecenter.startupapp.StartupAppListActivity")),
new Intent().setComponent(new ComponentName("com.oppo.safe", "com.oppo.safe.permission.startup.StartupAppListActivity")),
new Intent().setComponent(new ComponentName("com.iqoo.secure", "com.iqoo.secure.ui.phoneoptimize.AddWhiteListActivity")),
new Intent().setComponent(new ComponentName("com.iqoo.secure", "com.iqoo.secure.ui.phoneoptimize.BgStartUpManager")),
new Intent().setComponent(new ComponentName("com.vivo.permissionmanager", "com.vivo.permissionmanager.activity.BgStartUpManagerActivity")),
new Intent().setComponent(new ComponentName("com.samsung.android.lool", "com.samsung.android.sm.ui.battery.BatteryActivity")),
new Intent().setComponent(new ComponentName("com.htc.pitroad", "com.htc.pitroad.landingpage.activity.LandingPageActivity")),
new Intent().setComponent(new ComponentName("com.asus.mobilemanager", "com.asus.mobilemanager.MainActivity"))
};


for (Intent intent : POWERMANAGER_INTENTS)
    if (getPackageManager().resolveActivity(intent, PackageManager.MATCH_DEFAULT_ONLY) != null) {
            // show dialog to ask user action
        break;
}
