well, I would certainly discourage the use of a mobile phone to record yourself.
Anyway, if you must, you may use Ireal-pro and its record function (wear headphones) that allows to set the recording volume so that you will not incur clipping.
As for where to record, you can try to put a few blankets around the area where you want to record. A dedicated device, like a Zoom recorder, will certainly work better but you still have the problem to isolate reflections.
