After you take this update, you may need to look through the Application Manager Downloaded Apps to find all of the apps that you do not want installed and to uninstall them. I found that Uber, hotels.com, and a dozen or so games had been installed during this update. As I understand it, DT Ignite does these installs, and although I usually have that turned off, I have always turned it back on before taking an update in case there is something it really needs to install as a part of the update. Then I turn it off again and uninstall all of the unnecessary junk that it installed.
I'll tell you one thing I did notice on the new update... It seemed like everything on my phone was just... faster. Noticeably faster. So, I ran the Antutu Benchmark test again, which I do from time to time just to keep track. Not having installed nor removed any other apps, my before test was just over 50,000. My after test was well over 69,000. So, I wasn't imagining anything. It really did speed up my phone. Has anyone else noticed this?
