I have had quite a few issues with my Note20 Ultra. First off when I am viewing a youtube video and minimize it, if I try to do anything else my phone starts to glitch. My wifi seems to often disconnect at my work. I previously had a note10 and never had issues. Now many of my apps seem to automatically crash. I have even noticed if I have my google maps open it will become glitchy. I am not sure if this is a defect or something other people have experienced.
