Help me get a new phone. Please please

The phone I am now using is the one in the picture.
half the screen is black.
not only do I not have fingerprint recognition I don’t have a home button at all.
my screen is cracked and there are pieces about to break off.
thus is not a joke I genuinely use this phone I can’t afford a new one.
i am saving up slowly and would really appreciate any contribution no matter how small
thank  you !
