  1. Hello Gogi,

    I did not getting this update in my phone.
    Can you please answer me about this update & how to get it ?

  2. Worst ever update from OnePlus. It has bought in many new features but enabling VoLTE has screwed the phone. There is frequent network drops and battery life is very poor due to it. Especially the network drops has effect only with people who use Jio sims and another sim.

  3. After update of Oxygen OS 3.5.5 Facing network problem if mobile data is on but network problem is automatically getting resolved if using wifi or switching off mobile data

  4. Can Letv Max also be made to use Volte by using any custom ROM gogi ji? Since Oneplus-2 was also not having Volte feature before the update.

    1. Any 4G phone will support VoLTE, depends if brand provides update to enable that if not already enabled.

        1. In that case, my Letv Max and Oneplus-2 both have almost the same hardware. That’s y trying to find a way in which Volte cab be enabled by using custom ROM. Currently using Jio4gvoice app for calling.

    1. I am also facing network drop issue and also draining battery fast, more heating also observed.
