GPSTAG configuration download

hi dear gpstag developers,

using the gpstag more and more i found the following problem:

correct configuration for "endcustomer" is much to complicted. so we do configuration for them, they send huge amount of cellphones and we have to
1.) configure device to OUR playstore/appstore account
2.) download the app
3.) configure the app to our needs (round about 50 clicks)
repeat this with for example 50 smartphones.

it would be great (especialy for android), if we can download the actual latest android version directly from the browser (without the playstore)
AND just use username/pass (or drivername or something like that) and device will automaticaly download a pre-configured configuration (for example with custom sensors etc)

That would make the usage much easier...

Wolf.
