Samsung S8 - Push not working

[AWS2P]

Hi,
on a fresh 3cx V16 SP1 cloud on OVH, with SBC on the other side, every thing is fine excepted one Android phone (Samsung S8 - android 8.0.0) push is not working for this phone.
I've other oldest android smartphone and they are working properly. (one android 7.0, other 5.1.1)
i've a firebase project set.
3CX clients are installed from this morning
the only thing working is the missed call notifications which are coming live

i've done lots of tests call with wifi or 4G with no more success. i reboot SBC, i change all power saving to disabled.

This is an extract of server log, i've tried to call ext 001 from ext 200 (200 was out of remote location)



the call flow seems good but 001 never wake up ,no more rings, calls are working properly only when 3cx client is open and focused on.

Is there a fix for that phone?

Hi,
Am i alone with this problem?

Hello @aws2p

Check the phones power settings and make sure the 3CX client is excluded from any battery saving settings.Newer Android software is very strict when it comes to battery consumption. Also make sure that the client has all permissions enabled and notifications are allowed.

Hi @YiannisH_3CX

Thanks, except error on my part, I have already done these checks, the missed calls notifications arrive without worries . i will check once again Friday afternoon when i will see my customer.

For now , have done a new complete check on the phone and i found only a wifi password error so the phone stay on 4G even wifi was enabled but not connected.
Now password is good and phone connected to wifi, push is working fine, but not with 4g alone.
