Cherry Mobile Flare S3 Power was one of their many devices that they promised to have a Lollipop OTA update. If you are planning to buy one and you're quite into the newest OS possible then this is a good timing for you.
From this picture from Jeriane Sanchez of Cherry Mobile Flare S3 Power FB group, she got a chance to buy a Cherry Mobile Flare S3 Power with Android 5.1 Lollipop out of the box which is great. She bought it via Lazada Philippines.
Before I had this blog post, I went back to Lazada Philippines website but kinda confusing that their specs are still in Android Kitkat. If I were you, better to verify it first on Lazada PH's hotline. Another good thing, it is now at Php 3,999 from it's intro SRP of Php 4,999.
