    Its 3rd day and and i am going to review this rom

    1. smooth ui and stable ROM
    2. Battery backup is far better than stock rom and yu open os ROM.
    3. Many handy features included like colour engine and privacy guard
    4. No heating or lagging problem

    1. Slow charging (approx taking 4 to 5 hours to 100% charging )
    2. phone vibration is not working anywhere.
    3. Gallery app is not working properly

    Please fix that issues॥

    Some Suggestions -
    Please include some features in new updates...

    1. Auto Call Recorder (like ASUS dialer )
    2. In built Root Access option (like cyanogen)
    3. Font changer (like Samsung Phones)
    4. Make the colour engine applicable on app drawer and main menu too..

    Final ratings- 4.8/5

    Thanks to developer team for hard work..

    Don't expect More from the 5k device
    I can't do any thing regarding your suggestion.
    Cz iam not the source maintainer for ViperOS Project to add them in the source.

    Demand to viperos team.
    Suggest Them.
    Your suggestions are like a cocktail..
    All Roms have some unique features u can't get all those in a one Rom.

    Better u make your own source with that features :)

    Gallery is working fine.
    Use hyper kernel for charging issue .
    Once calibrate it.

    Thanks for your review.<3
    ya sure!!!

    Looks good...
    Hope it will be updated by Dev.

    BTW I think this thread is in wrong section. It must be in ROMS, KERNEL etc section.

    dont have enough thanks to post in roms section!! soon i will push:eek:
