Comment (by Marton Balint):

 You might want to try using the -ignore_length 1 option. In wav fiels the
 data chunk contains the wave data and it has a 32 bit length, so if your
 phone writes some random data there instead of UINT32_MAX, then that can
 limit the read audio.

 Alternatively you might want to upload here the first 64kb of some of your
 samples which are > 4GiB so we can check if there is a pattern which can
 be used to autodetect this...
