Microsoft failed its devoted and persistent mobile fans from a number of standpoints recently, but what likely still hurts the most is not Windows Phone’s global free fall in terms of market share. Instead, it’s certainly way more disappointing to see so many old Lumias initially promised a swift W10M promotion either left stranded on WP 8.1 for good, or kept waiting far longer than expected.

Verizon’s Lumia 735 is part of the “lucky” latter group, finally scoring its long overdue Windows 10 Mobile update, mere days after the Lumia 640 on AT&T. This is of course an OTA affair, but first things first, you’ll need to download and fire up the Windows 10 Upgrade Advisor app.

That’s going to tell you exactly when you’re due for the highly anticipated OS makeover, also helping you free up storage space, if necessary. You’re looking at software version 02171.00002.15194.03084 once the installation process is completed, which equates to W10M build 10586.318.

Remember to fully juice up your (tiny 2,200 mAh) battery beforehand, and beware of various bugs, as Redmond continues to have trouble ironing out certain kinks. If you’re lucky, you’ll end up with a prettier, smoother UI than ever before, “tested to help optimize device performance, resolve known issues and apply the latest security patches.” If not, the exact opposite could apply.

The fall 2014-released Nokia Lumia 735 was rebranded under Microsoft’s banner roughly a year ago, when Big Red picked it up, still selling for $120 outright with a 4.7-inch 720p screen, quad-core Snapdragon 400 SoC, 1GB RAM, 16GB expandable storage, 6.7MP Carl Zeiss rear camera, and 5MP selfie shooter.
