Dear,
The UMI-Z does never come ON with the WiFi active. I switch the WiFi ON manually in settings. The UMI-Z switches the WiFi OFF after about 30 seconds unless I manage to use the WiFi connection immediately after having switched it ON. I have deactivated all "power savings" of the apps, but it did not change the behaviour of the WiFi. If I manage to use the WiFi connection immediately to for example download news, it completes the download and switches OFF about 30 seconds later.
When I switch the WiFi ON the telephone responds with the message : "Battery profiles changed. You have to change the WLAN state, do you want to change the battery profiles" I have to reply "OK" else the WiFi does not come ON.
I did not have the problem with the WiFi before the 2017-04-11 update was installed.
I have in the order of 5 users of my router. I have no difficulties locking on to the router once I have switched WiFi ON.
My question was really meant to be when the next OTA update will be available .
It is really annoying that I can't use the WiFi connection.
Please, be honest and tell me whether the UMI-Z is a bad choice. I understand the delivery was delayed due to problems in the manufacturing process.
