Samsung GalaxyS9 turned into garbage after software update

[Random_Ized]

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.

What app needed to be updated? It's certainly not a Samsung system update as the device hasn't been supported sine April 22

Bogus update I suspect. Was the update from a 3rd party?

no i hadn't done that update yet since i didn't deem it neccasary until an uo told me i needed to be on the latest version of software, but it's all fixed i did a hard reset

By powering down my device and pressing volume up, bixby key, and power button at the same time i managed to do a reset

I have this exact same problem, I havent updated my phone software since 2020 so I said why not do an update, now "No SIM card" and my phone is very laggy.

Please tell me exactly what u did to fix this without doing a factory reset?
