[Q] i9300 faulty wifi?
My brother has a problem with wifi signal on his s3. He only gets good signal standing at less than a meter from his home router (the same happens with his work router). If he goes away, say, 5 meters, he totally loses the signal. We compared his phone with my s3 and his wife's s3, and we both get full signal where he gets none at all
His phone had samsung stock 4.3 unrooted rom. We tried, without improvements:
1 - Factory reset
2 - Root and changed kernel (yank555)
3 - Full wipe (with TWRP) and installed 4.3 samsung stock rom again through odin (and then root)
Don't know if I'm missing something, or if it might really be a hardware problem. What do you think guys?
Thanks in advance!
