Repeated transfer timeouts

[AnrDaemon]

MyPhoneExplorer client 1.8.12
MyPhoneExplorer app 1.0.66
Nokia 2 Dual Sim
Connecting over WiFi

I hardly can transfer more than a few (5-20) megabytes of information before catching

Code: Alles auswählen

---------------------------
Error...
---------------------------
SetPath failed: …

OBEX Errorcode: 00 - Phone didn't answer, Timeout
---------------------------
ОК   
---------------------------

When this happens, app on the phone indicates that connection exists and/or the transfer is in progress. (The notification icon is spinning.)

At the same time transfer to an older tablet works just fine.
I already tried to change "Standby mode" setting to no effect.
