If /data/local/tmp isn't accessible (writable), Tramp has problems,
because it uses it as temporary directory on the phone. Pls check why
this doesn't work.

The Tramp manual speaks about problems of the temporary directory on
non-rooted Android devices, and it shows also a recipe how to change
this. See (info "(tramp) Android shell setup")

Best regards, Michael.
