There will be several A/D converters in most cell phones (to
digitize the speech, to digitize the received signal before
processing it, to monitor the battery voltage, ...).  They are
probably all of the SA type.

A flash converter would be used in a digital oscilloscopes
because very high sampling rates (100's of MHz) are required but
6 to 8 bits of accuracy are sufficient.
