Try to go into browser settings, then display and actions... then reset search engines

Also go back and enter privacy and security then clear history and clear cookies and other data

Close browser

Then press volume up and down until you see blackberry logo and let boot then try again to use browser

When I get slow speeds I take out the SIM card and put it back in.

If you test the new OS if you have apks on your phone and all BlackBerry data will be gone if you want to go back to 10.2 even if you backup your phone. I backed up my phone to test the new OS it was to buggy at the time so I went back to my old OS. When I restored my phone all my data was saved but some apps BlackBerry and Android where missing also with some settings.
