  • What region are you located?

Internet Service Provider and Modem Configurations
  • What ISP Service do you have? Cable or DSL?

Was a factory reset and setup from scratch performed after updating to v1.07?

There are no manual channels to select from as COVR systems are based on Smart Connect which auto assigns channels

Bridge mode on the 1203 is actually AP mode.

What is the Mfr and model# of the ISP modem that is in front of the 1203 system?
I would factory reset the 1203 and use router mode on the 1203...

Which forum did you see this issue with Android devices?

i Found the solution its was Volte (voice over LTE ) if ts on the internet will be very slow and if its off the internet will be fast and work normal

but i think Dlink should find fix for this problem.

Is this VoLTE a feature if your isp modem or the android devices? Where exactly did you disable or enable this feature?

its in android devices
you can disable this in connections --} Mobile networks --}
Volte calls.
but this is temporary solution i thinks Dlink should check this problem and try to fix it.
and some times i have to enable flight mode first to fix this problem.

i try this fix in 3 android devices samsung S7 S8 S8+

Not sure of this is a D-Link issue or Android issue.
You might check with the phone Mfr for help and information.
You can also contact your regional D-Link office to see if hey can help. Might notify them of this issue. Haven't seen this issue else where at this time.

I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this.

We find that phone contact has better immediate results over using email.
