New phone before upgrade
I am disabled and having a hard time with the touch screen due to bluriness in my eyes and hands shaking. It is difficult with the touch screen i am constantly typing the wrong letter. Would be much easier for a keyboard. How can I change my phone earlier
Check phones from Nokia and Samsung. Samsung is releasing soon a phone with touch screen and dedicated keyboard, not on the screen. That might help. How to do that? Sell the one you have and buy another.

But all depends on how much you can afford to spend on a phone. There are cheaper phones that have keyboards.
