Google started to roll out the Android 4.2.2 Jelly Bean update for the Nexus 7, Nexus 10, and Galaxy Nexus, a couple of days ago. Now, the users if the Nexus 4 are beginning to receive the firmware upgrade, as well. While, firstly all the LG Nexus 4 may thing that this is good news, they might think about whether to install the update or not, because the software will remove a very important feature. It seems like the Android 4.2.2, apart from coming with some nice functions, it will also disable the unofficial LTE support.
Even though the search engine giant didn’t advertised the Nexus 4 as a LTE-friendly terminal, the latest member of the Nexus tribe is definitely compatible with the 4G LTE networks, as it’s based on the same Snapdragon S4 Pro SoC of the Optimus G, which comes with a Qualcomm WTR1605L LTE chip. After, the Nexus 4 was launched, the guys from AnandTech and some users of the XDA Developers forum, played with it for a while and found out that not only the device had partial LTE support, but it could also be used.
Nevertheless, the smartphone was never meant to have LTE support, so the users could only use Band 4 (aka AWS) which is used in most Canadian regions, but not so widely in the US (even though T-Mobile wants to roll out LTE via Band 4, there will be a while until it could be possible).
Consider using the LTE connectivity on your Nexus 4 as a back door that not so many users have access to. Well, the Android 4.2.2 Jelly Bean will definitely close that door, so if you still want to have access to those settings, you may want to leave the update for another time. Moreover, in case you want the LTE connectivity of your Nexus 4 to remain intact, you better start praying that the unofficial ROMs have are able to restore the hidden function. And for the users hopping that Google will release a firmware update that will offer the official LTE support, nothing is impossible, but there is a big chance that will never happen.
