More stable than MIUI. NEVER THOUGHT A CUSTOM ROM WOULD BEAT A STOCK ROM'S PREFORMANCE. But I think USB OTG is not detectable in my device. Is it unsupported?

Real good ROM must try if you want real stability

Pros :
Real lightweight feels very smooth
No complications in venom configurations
Solid battery life stays for 4 hrs on continuous YouTube 720p videos
Camera quality is the best in all customs I've tried

Cons :
Just lack of customization and that is not intended.

Do try this for extreme stabilty. Highly recommended. No **** Real good experience.

Well, i want to give a short review about this rom,
First, im using 1GB variant, and its working well. but there is a couple problem with Magisk and internet speed download.
i can't launch Magisk from settings, its always force close,
and the internet speed is so worse, i have 15mbps , but i just get around 200kbps.
i have try to restart my phone and my wifi. but its still giving me about 200kbps.

    Kinda review

    I've been using this ROM since two days. Today is the third day. I won't tell anything about the ROM, what I felt on the day on which I installed the ROM. So this review is based on the usage on the SECOND and the THIRD day.
    Talking about the SECOND DAY
    Didn't play any game. Only surfing the web, watching videos, music over wired headphones and earphones for hours, multi-tasking between the social media apps [I used Facebook, Whatsapp, Twitter, Instagram, Messenger], used these apps for the whole time the phone was on, didn't used any battery saver app, greenify, the native android battery saver, and managed to get a screen on time of 4 hours and 27 mins.

    Talking about the THIRD DAY
    What all I did was my daily routine so I did all that on the THIRD day as well but on this day I added two more apps. These apps were actually games. So I added Vertigo Racing (78 MB game) and Asphalt 8 (45MB app+ 1345MB data). I unplugged my device at 7'o clock in the morning (IST), did all my social networking and stuff, also downloaded and played these games, played Vertigo Racing for 15 mins and Asphalt 8 for 15-20 mins. Also downloaded them on the THIRD day only after unplugging. Vertigo Racing was downloaded very fast since I have a decent internet connection and the size was not that humongous. When I downloaded Asphalt 8, I turned the screen off and still saw 4-6% battery drop when the download finished. And as that 4-6% battery can change the battery life of a day (not very much but yes it can) so don't get mistaken by seeing the battery life. I'm dropping the links to the screenshots of the battery stats and the screen on time. It is just for the THIRD DAY!


    Talking about the camera
    The camera is good, I never used the MIUI ROM so I cannot compare but yea, the camera is good.

    Talking about the features
    It is having nice customization options but what really lacks for me is the Lava Pulse in the navigation bar. Other than that, ROM is really fast and fluid, multi-tasking was not an issue.
    If you want to see a dedicated video of the review of this ROM tell me ;) I'll be happy to help.

    Talking about the GAMING PERFORMANCE
    The phone along with this ROM ran Vertigo Racing smooth, no issues.
    Asphalt 8 was smooth on the medium settings, it was not the smoothest but yes it was smooth, the game didn't crash which I liked the most! When playing the game on the highest settings, the game was sluggish but was playable.

    As of now, this is the best ROM I have used on my Redmi 2 Prime.
    :good: to the developer.

    If this post helped you then don't forget to hit the THUMBS UP BUTTONNN!!!
    Wtf is wrong with u developers u give an update to make improvements or stop basic functionality ? This time the music doesn't play with earphones this is disgusting! Seriously you're not worthy of calling your ROM stable if this kinda **** happens plaza fix this I use my phone as Daily driver
    Who the hell you are for being rude like this , seriously , are you paying him his hard work or what,
    If u don't like his rom then u don't have to use it and stick with crappy miui rom...
    U guys demand features and one bug and everyone looses there mind. ?
