Three months ago I had a problem with speed transmision on lte. Speed limit app show me 1mb download and 20mb upload. The same sim card works properly in Samsung S6. So I send the phone to service and new software was installed. Every things was fine until now.
The problem began to occur again.
This time I change the sim card in my operator but it not help. I also made factory reset without any result.
In settings I change preffered connection type from Lte to Wcdma. On Wcdma internet connection works better and faster then on LTE.
Should I send the phone to service again or maybe it is software problem ?
