    I'm running this but not noticing any improvement in Wifi range or GPS lock.

    Which of the previous ROMs, if any, showed any improvement in Wifi range ?.

    Ok, I've played with it a while longer & noticed something weird with wifi. If I'm using the stock browser & have a good wifi range but if I'm using the Facebook or Messenger Apps then I'll have no connection unless I move closer to the router. Weird but somehow the apps must be not optimised for wifi control.

    I've never even had a single satelite lock on the phones GPS so I've given up on that, I've a GPS bluetooth receiver instead & that works well with Google Maps on the phone.


    Everything else seems to be working very well.

      GPS is really a problem, i´ll ry to mod my antenas from wifi and ps and mobile data GSM… this schould help, because some MTL phones with exactly the same chip have a good GPS performance, the problem is just the antena, but i dont understand umi and other manufacturers, this is not that hard to make a good antena for the phone …

    I have one question please – is 3G connectivity fixed in your ROM? that seems to be real problem of factory delivered ROM. (other than poor WiFi range)



    P.S. ready to donate :-)

    Great ROM, I have the ODEXED on my Umi X2 and with Antutu 5, I was able to get over 18000 score points. Plus this ROM never crashed on me. No reboots, it just works. Thanks a lot.

    I have UMI X2 version 1 gig Ram. the big problem I have is the mobile network signal is really weak ( I mean the antenna). can you guide me to choose a good ram to flash my phone? which ram should I use?

      you mean rom ? you need to flash a custom recovery, the TWRP or Carliv from needrom, with a custom recovery you can flash the this ROM, the official firmware which was cleaned by me, no china apps, no bloatware, or the NEXUS ROM, which is very light, this is the fastest rom for the umi x2 right now

    @ Mr-Needrom

    thank you so much for guiding me. yes, I meant rom. I had wrong typing

    the last question, should I only download the NEXUS ROM and install it? by doing this, my problem will solve?
