My phone freezes more and more. I disabled some factory apps because they were filling up my storage and I am not interested in using them. I did a factory reset after I took out my SD card. The more I cleaned my phone, the more it froze. I put it in safe mode today. It froze a few hours later in safe mode, so it was not one of my downloaded apps. The metal or wifi at my job causes my battery to drain badly. I leave work at 30% sometimes. Their wifi is unstable and my network drops sometimes as well. Bad when you are contacting your supervisor. Which one is contributing to my phone acting up? Or is it all of them? Do I need a new phone?
