this has only started happening since the security update that i did a few days ago. started with the wifi not working and i didnt notice the problem untill i saw i was using data at home. when i tried to get my wifi working it would just freeze then i would get the UI has stopped working error. it seems that any time i click on wifi either from settings or the drag down menu it well freeze 99% of the time, same if i go to data usage to try and manage data.
iv already tried nearly everything iv read online for anything even remotly simular
