Firebase takes ~3 minutes to reconnect on Android

Question

The Firebase service on a Samsung SM-T560 with Android 4.4.4 takes ~3 minutes to re-connect (after I disabled wifi and enabled it again). This problem doesn't occur when the same app is being ran on a HUAWEI MediaPad T3 10 (AGS-W09) with Android 7.0.

I'm currently using the following Firebase version:

implementation 'com.google.firebase:firebase-core:16.0.8'
implementation 'com.google.firebase:firebase-appindexing:17.1.0'
implementation 'com.google.firebase:firebase-messaging:17.4.0'

I've registered 2 services in my manifest file:

<service android:name=".firebase.FirebaseInstanceIdService">
    <intent-filter>
        <action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
    </intent-filter>
</service>
<service
    android:name=".firebase.FirebaseMessagingService"
    android:enabled="true"
    android:exported="true">
    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT" />
    </intent-filter>
</service>

Edit: I've also tried to use a lower Firebase version:

implementation 'com.google.firebase:firebase-core:9.0.2'
implementation 'com.google.firebase:firebase-appindexing:15.0.0'
implementation 'com.google.firebase:firebase-messaging:15.0.0'

Sadly this didn't do the trick.

Does anyone have an idea why Firebase takes so long to reconnect? In Android 7.0 it directly reconnects.

Answer 1

I've received a message from Google with the following:

Hello,

This appears to be more of a device problem than a Firebase issue. The network is handled by the device, so when any Firebase service can connect would also be dependent on that.

If you have Firebase specific questions, feel free to reach out again.

Looks like I've to contact Samsung.

Edit:

I've contacted Samsung. They told me to reset the tablet.

I've performed a hard-reset and this problem doesn't occur anymore. Thank god.

This guide worked for my tablet: https://support.bell.ca/mobility/smartphones_and_mobile_internet/samsung-galaxy-tab-e.how_to_perform_a_hard_reset_when_my_samsung
