@Acil253

Hi @Acil253, welcome to our forum and I'm sorry to hear about this.

As @uliwooly asked, how did you update your device?

I would also like to know what options you have when you go to Settings > More > Mobile networks > Preferred network type, could you please take a screenshot of this menu? Do note that sometimes 4G is also displayed as LTE instead of 4G, however both of them are the same and the only difference is the name displayed.

Let us know how it goes!
