I am having 2 issues since downloading the latest firmware on my s4.
1. I cannot view a webpage unless I connect through wifi, if I try through mobile network I get page can not be displayed.

2. When my battery level reaches 14% I get a message to connect charger but my phone dies, won't switch back on again and when it does it shows either 1 or 2% battery life.
Any ideas please. Getting to the point I want to sell and change to Lg or Sony
