The answer to your problems is very simple...Stop complaining and start Developing.
There are too many "takers" and not enough "givers" in this community. If your device doesn't have something you want, then learn how to do it yourself AND then share it with the community.
I knew "absolutely nothing" about making an Android recovery when I first got my T210R. In fact, when I bought mine, we didn't even have a dedicated forum for the Tab 3 device line. I did not accomplish anything by myself, but I did learn how to do things as I went along (with the help of some great experienced devs). I still learn new things every day.
No experience is required to start learning.
This little rant is not directed at anyone in particular, so please don't be offended. I understand that these aren't the greatest devices, but you can help make them better.
