Update fails on Samsung S7 edge. The wifi connection is okay but when I try to update from e/OS 2.2. to 2.3 I get erro message.
I can download from normal websites without a problem. At the moment there is no sim card in the device but I can’t imagine that would make a difference.
I get error message download failed. Check internet connection.
