Check your updater, B330 is available.

Previous version we can set certain password or fingerprint for guest which we can choose which app or contact can be hidden from their view.now it's no more

1) download the file from here

2) extract the file.

3) insert the file onto storage. (i insert into my internal storage, but i think you can insert it into sd card too)

4) i) either update through updater app (i did this way first, it showed error but it did updated my phone to MM)

or

4 ii) shut down phone, then turn it on by pressing 3 buttons together - volume up, volume down and power button. but be warned, you lose everything inside your phone, so do backup first. (i did it this way, successful update without any error)

note: do at own risk, will not be responsible for anything.

already august, no OTA yet. 

Report in again after 12 hours see still got the problem or not

i dont have that option.

Which version you using now?

Mines is 2.16.259 from Google Play Store

so far B350 is treating me well, nothing special but no notification delay, so all is good.

Have you tried all other options?
