However a quick check back and it's LTE/GSM auto instead. Upon reboot, it goes back to WCDMA preferred.
I currently have AT&T PTA selected. Changing settings via Settings -> More -> Mobile Network Settings doesn't seem to have an effect as it's still set to WCDMA preferred on *#*#4646#*#* phone info.
On the 2/17 build with the default baseband , it is set to LTE/GSM auto by default on the phone info via *#*#4636#*#*. Changing it to LTE/GSM/CDMA auto preferred will only have go back to LTE/GSM auto. On Settings -> More -> Mobile Network Settings it says it's set to LTE/GSM/WCDMA but it might not really be the case.
Not sure what to do with knowing this. I'm going to keep the default baseband and see how the battery life is on it now.
Just keep the default baseband. We're due for an update from 2.20's radio files to 3.17's radio files in the coming weeks.
We're working on a huge thing right now. 3.4 kernel, which means that we can basically shadow the nexus 4's updates step by step. its on the side from what we're doing on nightlies right now.
3.4 kernel has no screen tearing, we can probably stop hacking our camera HAL and use nexus 4's instead, as well as many other things.
Basically, if all goes well, this phone will become a nexus4 on the inside, and an HTC One XL on the outside (casing). Thank LG/Google for using the msm8960 platform for its nexus, as it would not be possible otherwise. This is very exciting.
