Im posting this here as I havent managed to find a solution yet.
I have a German T-mobile 16GB d802, only the device was purchased and using it in Greece.
When I was using 4.2.2 everything was perfectly fine concerning LTE with my mobile provider.
After flashing 4.4.2, I noticed that I data traffic was not working anymore. After searching I found that my APN settings were gone, so I manually inserted them.
Following that, I noticed that when I am on LTE network and have data traffic enabled, I don't see the LTE icon on the top right corner on top of the signal sign anymore. The data traffic is working though, so it seems to be a missing icon for some reason.
In 3g/HSPA and Edge I see the relevant signs, the only problem is when using LTE
A friend of mine who has the exact same version of the phone has got the exact same issue on a different cellphone operator. So its not related to the network.
I reported this to LG using the local site, but got the reply that I haven't bought the phone from the local market and they don't know the changes made from tmobile..
On tmobile website you cannot report an issue unless you have a german tmobile subscription or for business issues, so I have sent them my problem stating Im contacting them for business related reasons
Anyone else got the same issue? Anyone using German T-mobile? Anyone who has any ideas?
