New Redmi Note 3g Wcdma Have Big Problem..

[zulkarneyn]

I have a Redmi Note 3G WCDMA. On the first release of v8, there was a 3g problem. 2g was fine but i couldn't be able to open 3g. On the next release, 3g connection was provided but network signal reduced around 60 percent. Even in the open field, i couldn't be able to get 50 percent signal. Later releases weren't fixed that problem. When i enter a building, i lose the signal completely. I have to use v7, there is no problem on that.
