Latest Report From LG States That The V10 Will Get The Update Q2 (March-May). We Less Then A Week Away From June And Still No Update....
How Long Will It Be Until Testing Is Over??
Neither LG nor T-Mobile will provide a definitive answer to your question. The primary reason is that they don't want to get customers upset. While creating and testing the update packages for individual carriers; the manufactures might encounter bugs and and other problems while making sure that the updates play nice with the individual carriers' proprietary software. Those unforeseen setbacks delay the release by the "promised" date. If a customer doesn't receive an update "as promised" that customer might become upset.
That is probably why LG might have stated a "definitively vague" target date for the Nougat update. I am going to guess that you added the (March-May) explanation of what Q2 means. I believe that LG was simply trying to provide some wiggle room in case the update took longer than expected. . . . beyond Q2. Notice LG didn't make the more definitive statement that the Nougat update would be available no later than May 31.
And here we are June 13....
