Dear experienced people,

What could be wrong?

I formatted my phone after changing the screen some days ago, since then I have been having difficulties browsing.

Whenever I am outside my living room - inside the fence and beyond it will work but immediately I enter into living room down to the kitchen and the room, it will stop browsing.

What could be wrong?

Note: My brother's phone is browsing inside the room.

Maybe the network receptor has develop fault, I would have said it's from your network provider but you said your brothers phone is working perfectly fine so I advise you take it to a repair center like carlcare to have it checked out. What brand is it btw?

Maybe while changing your screen, technician don tamper with something that has to do with maybe signal or antenna .
