If I run the speedtest on the phone and take different speed test, that is faster from the upload and sometimes slower. On the playstation is always slow.
You compare two different systems - the result is normal.
In other words, a Porsche is faster than a Trabbi.
To play 7mbit upload are more than sufficient. Why is slower on the PS4 can z.b. On the PS4 servers are the upload test.
How high is the upload so on average on the phone? What difference are we talking about here?
What's slow about that?
What do your other devices show?
For comparison, the test should always make the same server with all devices…
95 down and 36 upload to mobile
