It’s apps I use. My point is it has what you want. Do you even know what homebrew is? Have you been on that site? Doesn’t sound like it. The App catalog sucks. Here’s the link: http://forums.precentral.net/homebrew-apps/
Yet I am on the my original phone and have NONE of the issues you list. Interesting. Maybe it’s the user (don’t know how to take care of the phone? Have you dropped it? Been in water?)
My phone has ZERO issues, no lag issues, etc. Why don’t you research ‘homebrew’ and get the tweaks before you talk out of your ass.
