Okay, since many people are having this problem lately, i will show the solution that worked for me and for others around the web. My wifi range suddenly was reduced and I still don't know why. If you are having the same problem, you should try this procedure. I dont have a Mediatek(KATE) version to test, so if someone can do the procedure and report back, I would appreciate. On XDA I saw bar4's guide:
Consider we are looking the smartphone from the back. The problem I had with bar4's guide was that he glued the aluminum to the right side contacts, while he should have glued it to the left side.
Other possibilities are that the continuity between contacts was broken(in my case, on the left side) by a fall or something. Before doing the procedure, check the continuity between each pair of contacts on the top pieces. If the current is not going through, you've found the problem. Maybe bar4 had the right side broken. I created this thread because there is almost no info about this procedure in the web.
Spread it out.
But in the pictures, he glues the aluminum foil to the wrong side of the piece. The correct was to do the following:
- Open the back cover;
- Remove the 4 screws on the top piece shown in the pictures;
- Cut some aluminum paper or foil in a size that cover the two grey contacts and place it above them with a dot of scholar glue; (Pay attention to the side of the piece)
- Put the top piece back on its place and insert the screws.
- Do some testing
