yes, those materials works as well (all aluminum materials works)
I have watched kenzo teardown video on youtube.
It means wifi , bluetooth and gps antennas are on the top either left and right side. Dont know which one is left or right.
But 4g and 3g antennas wire is connected from mainboard to charging board on left of battery. And both 4g and 3g antennas are located at bottom near micro usb . so what happens if we apply aluminium foil along bottom edge? Did anyone tried and tested for any network improvement?

yes, you can try to stick the aluminium foil directly on the wifi circuit or may be you can follow us to stick it on the case.

Can i use foil from pharmacy tablet or capsules.
What about network antenaa. Which side it is located ?
network antenna work perfectly for me, not sure about pharmacy tablet.

Top right are wifi, bluetooth and gps.
Top left is diversity rx antenna. Rx mean receiving signal. And bottom is tx antennas for transmitting signal for 4g and 3g.
that's right, but i can't find the tx antenna on the bottom, can you give me the full picture? the picture above is cropped.

i tried with silver foil and aluminium foil with which the food is packed and delivered :p. i didnt stick it to the case or the board, but i just kept the silver foil over the board and locked the case leaving few millimeter of the silver foil outside. My wifi never breaks now, i think my network reception also has improved with silver foil. People can try with silver foil than aluminium and give feedback, so that it might help others. For me silver foil works better than aluminium foil.

thanks

Solution I found

My wifi did not work at all, and finally I was able to solve the problem and relive my Redmi Note 3 PRO - RN3P Kenzo.

I opened the back cover, removed the screws from the top, and removed the part (that protective plastic). With a multimeter I measured the continuity between the points, and I noticed that the left part was not giving continuity between the points.

So the step by step is as follows:

1- Remove the back cover
2- Remove the screws from the top and remove the plastic part
3- Place 2 small sheets of aluminum on top of the contact metals
4- Place the plastic part without moving the aluminum foils
5- Close the back cover.

If anyone has any questions, send me a PM. I can not send images, but if you send a image to me I can help you.

The steps above didn't work for me too, your solution work perfectly for me...

* Redmi Note 3 Snapdragon : wifi circuit is on the right side
* Do not open the screws, it will broke your warranty!!
* Take a small aluminium foil, attach it to the left side of your phone case (i use a thin double tape)
(When you attach the case to your phone, the aluminium foil will stick to your phone's wifi circuit)
* It works like magic :)

I have the image, but I'm new here, i can't post image.
Not able to upload it here :(
can you be kind to share it also to me,

thanks in advance

My Wi-Fi is suddenly disconnected! This disconnect is performed several times a day, and it interrupts and reconnects for a few seconds each (approximately 30 seconds) Doing this will fix my problem and my Wi-Fi will be permanently connected?
