+$Galaxy$ $S2$ and $Galaxy$ $S3$. There are two possible explanations for this result.
+This might be because the newer AGPS devices require more assistance data
+by relying on the network providers to have synchronized GSM systems or it is an
+security protection of the smart phone user. No information on the AGPS receiver
+chipset in the smart phones could be found online and author's given statements
+have to be considered with ambiguity. Another contrary to expectations, were the

+RRLP requests with assistance data did not produce any output from these smart phones
+\citep{nokiae71} \citep{nokian95}. The reason for this is not clear but it might
+be due to the fact these are older models in comparison to other smart phones in
+the tests. At the time point when they were released by Nokia the firmware for the phones
+might not have been fully evolved and developed since both models are from the
