S2 Pro cell service not working while WiFi is active

StijnS

\n\nUmidigi Tech Team,

I can't receive any calls or SMS messages while my WiFi is active. It works fine when WiFi is off, but I do not want to keep toggling between the two. Especially as I dont know in advance when I get calls or text messages from others.
Please look into this and fix it.
I use my phone on Dutch T-mobile Network.

If there is any other information required from my end, please ask.

Also, almost no app gives any notifications even though I turned this on in any possible place/setting I could find.

Todays update to the OS hasn't fixed this problem.

Turns out it wasnt related to the WiFi, but the 4G reception. When I switched to 2G/3G only everything seems to be stable.
I'd very much prefer the 4G though, so please look into this.

Also the notifications work when I manually launched the app and make sure it doesnt get cleaned out of memory. Is there a way to set other apps besides Whatsapp (that works perfectly with notifications) as a 'always active' background app?
