#### It's not working for me #### #### A Word On 4G SUPL Support ####
I've tested `suplpatch` with Xperia X and get an A-GPS fix in less than 10 seconds even if the device wasn't using GPS for many days and ephemeris data was expired. If your device is connected to a 4G network (LTE) **SUPLv2** is mandatory to query the SUPL host and make things working. Sadly SailfishOS currently has no configuration options for this and hybris bindings to override the modems default setting when GNSS services are started.
Deactivation of SUPL TLS was verified by proxying requests from a public server to supl.google.com and examing the requests. No TLS hello package or other handshake overhead was send so TLS deactivation works as expected. A solution for this is to change the modems default SUPL version from v1 to v2 using the `--supl` flag.
```

If you don't worry about your privacy you should simply disable SUPL TLS as TLS handshake uses more traffic than plain SUPL request/response itself. If you don't worry about your privacy you should simply disable SUPL TLS as TLS handshake uses more traffic than plain SUPL request/response itself.
