Could you please write some more about your attempt of replacing  rome's genuine battery with hammer's one? Does it fit to rome's body without problems? Can the back cover be shut on place? Can the phone stay longer on power between charging? I'm very interested in your experience.

The antennas problems with Umi is commom to all versions, included GPS, 4G and WI FI. The problem is very simple to solve. The problem is that the WI fi , 4G and GPL antennas that are on the internal mother board plastic cover inside Umi, are not enought pulled up to touch on the other part of the Umi specific hardware in motherboard once you close this plastic cover. Solution is open it and pull up a little bit each of this pieces of metal atachhed to the motherboard antennas plastic cover.

May be Umi factory employees are not real Umi employees, they are sub contracted factorys to lower the production prices at Umi levels. And you know this guys maybe give bonus if an employee surpass a certain productivity, and they dont bother to loose time pulling up a little bit more each antenns because it will take more time... ;0(

You need to remove 1st cover, then this cover and you will see pieces of metal that are not enought up to touch the hardware connections of wi fi, 4g and Gps in the mother board, so once you close this cover you will see this pieces of metal dont touch it or stay only very close to it.

With an precision knife like X-act or other you need to pull this pieces of metal a little up on a way that they touch the hardware once you close it.

After this my GPs started worked more faster and accuratly then ever and 4G internet speed and ping goes to the roof . Amazing !

I have here some you tube videos explain how to open this cellphones and solving the antenna problem as well in a Umi model . In the side of the hardware motherboard it is written Gps . . .
