The issue haa been fixed

So after an app required me to update to the latest software to make some changes i did. After doing so my phone has been suffering from multiple issues with no fix in sight. It's been said some small preformance issues would occur for aroud a max of 2 days, it's been 4 and counting. Here's a list of some of the issues:

• My phone doesn't read my SIM card anymore
• I can not log into any samsung account anymore
• IMS and Samsung Experience something something keep stopping
• My phone has slowed down so much to the point i might aswell start writing a book whilst doing anything and with anything i mean anything, even turning on my flashlight has a delay now
• my battery life has severely decreased, almost like 30+ apps are constantly running
• Airplane mode is in a weird stasis where it's toggled on but greyed out
• I can't reset my phone to fix the issue because the samsung account that is saved for some reason is my old one with a deleted email, and i can't log into my other samsung account because it will just tell me "proccesing failed" 

everything was perfectly fine before and now it all sucks, thank you samsung.
