I have been having troubles with my 5 year old Xs Max for two months now. The only things I can do are use instagram, call people and send text messages. I am logged out of my imessage thing and when i click on it to put in my phone number and choose my account it just keeps on loading and never fully loads. I dont think this is an issue with my actual data as I can use instagram although I have to refresh each time I want to see a message. I cant use my home wifi, other people's hotspot, and other place's wifi. Its saying I am connected to the network but it does not come up in the top right corner and always says i am using data. I cannot use safari, google, chrome and even the app store does not work. It just says its loading but it never loads. This also means I cannot update any app or install an app that I have already purchased. I have tried updating it but it also couldnt do that, I even tried updating it by connecting my phone to my laptop and even though it installed the update it could never actually update the phone. I just tried to fully reset my phone but it is saying it cant do this due to some error (akauthenticationerror code 7005). I then tried to sign out of my apple ID but then this also didnt work. It told me an error occured and this couldnt be done.
I was wondering if this is is happening just because my phone might be too old but maybe there are some other issues? Thanks
