Another thing, did the back cover stay attached perfectly after you've re-assembled it? I mean using the heat gun on it didn't make it permanently loose?

What about water-proofing?


Hi. Finally it's working and yes the cable was loose. It's really easy to open the phone. It's the cable on right it's grey and silver ( like on picture) You can buy new original adhesive tape on ebay for £5. I don't know about waterproofness after. I will try when I will get new phone. Hopefully ultra2

I'm surprised you'd even want a new one after dealing with that. Hopefully I don't need the original receipt to get warranty service. I hate the idea of opening up a new phone to solve a problem with a home remedy. As you can tell I am suffering from the same issue.

3G and 4G can have poor reception indoors. See if switching to 2G only helps, even if you don't have mobile data enabled.

It was the only way to normally use the phone. It took 5-10 min and now it's working perfect. Try with Sony service centre, I hope they will do it for you. It's best phone ever, I hope they will make ultra 2.

P.s : nexus 4 has full signal on wcdma but xperia has no signal/poor signal even on edge/gprs ...

As you can see in the picture, every phone tested with that sim has full signal in the same place. But not the xperia ... I think it's "blessed" ...

Smile a weird solution that worked for me
Hi guys I had the same issue and solved it finally
First I tried your method and checked the antenna cable mine was already in place and fine so I was depressed and closed the phone back.I tried every thing else rebooting,repairing through companion,updating the rom, changing sim, changing network and every thing else. Finally I took phone into service they returned it without the issue and I was pleased too much, but same issue returned after 2 weeks
So I tried a stupid thing that worked like a charm I put 2 pieces of paper under the sim and above the sim metal holder and inserted the sim back then the issue was solved and network is like any other phone finally
It worked for me and I think it may worse a try

I Just bought my New Z ultra Last month. At beginning i thought that my Z ultra poor signal were normal (90-110 dbm) until I compare to my friend's Z ultra. I realized there's something wrong! I was hopeless till I found this thread. Thanks to Al3xxxinho it worked! The antennA were loose also. Easy to open and I didnt see it Will break the warranty seal if you open, and the back cover still fit perfectly. Now I enjoy full signal bar.
