So I updated my s9 to andoid pie and for some reason i have an H icon next to the signal bar and cant connect to the internet, the phone and text meseages work fine. I downgraded to oreo and evrything works fine again, im too scared to now update software because of this.... Iv tried looking through forms but cant find anything
It means your signal is HSDPA.
Have a look at this https://lowdown.carphonewarehouse.com/how-to/what-do-the-symbols-on-my-screen-mean/29341/
I know the whole H thing, but with android Oreo its 4g with everything working, internet, phone, etc, but when i upgrade to Pie i have a H with no internet but can use the phone/text, same place, same phone, same sim
