s8 4G connection is very slow

[TechDiff]

hello everybody,
has anyone experienced very slow 4G speeds on the galaxy s8 ? maybe after oreo update ?

and NO please dont tell me to check the service provider .. because i took the sim and installed in an older phone and i got speeds around 15-20 Mbps ... but on my **** s8 i get bearly 1.5 Mbps !!! what gives ?

can i check if i have problem with my 4G antenna or any diagnostic methods to determine the problem ? all tests i can run says everything is fine...

this is not a device issue dude

[TechDiff]

how ? ... i used the sim card on a different device with LTE/4G and worked fine ! so clearly it's not the service provider

you should see the network access point setting
go to mobile setting >connection setting >mobile network> access point name > you check your sim provider server address , MCC ,MNC etc . i'm from Pakistan 🇵🇰
i will send you screen shoot .!
