hi, anyone know where is the antenna located in the lg v20? TIA!
I had it replaced… It is just as bad. The worst phone ever. I will never buy LG anything again. LG is dead to me. Buy their $@$* at your own risk.
The LG V20 has two antennas placed near small polymer pieces that serve as bumpers. One antenna is located near the top of the phone while the other antenna is along the bottom.
Get it replaced, my v20 has best cell reception ever yours must be defective.
I am on my 2nd LG, a V20. I bought it because the first LG died so it was more of a replacement, not a new purchase. It has never worked inside my home while my wife has an older iPhone which always works. We are on one of the big 3 (I won’t mention who as I refuse to advertise for them). I have an ap that measures the signal strength and the BEST I have ever had inside my home is -110 dB which is basically NO signal as -100 is considered the bare minimum or zero signal. The carrier says it is not their problem and LG says the same thing. The phone works reasonably well outside the house but what good is it if it does not work inside my home? BTW, the 1st LG had the exact problem. One thing for sure is I will NEVER buy another LG phone. For the record, I am NOT working for a competitor or any paid hacker or troll, but a legit phone owner. On a side note, we bought an iPhone off eBay that was advertised “New, in original box” with warranty. After 3 months I had problems where the phone stopped charging so I took it to the Apple retail dealer who plugged it in and much to my surprise found out it was 2 years old! He showed me on his iPad screen the original purchase date along with a repair made in 2017 (it is now Oct 2018). Man was I P/O’d! He said he could not give a copy to me but he could show the eBay fraud dept so we communicated with the seller who dragged their feet so I went to PayPal who finally refunded our money. So buyer beware! So is there a solution that solves the crappy reception on the LG V20?
This is an update to the never ending quest to figure out the antennas on the LG V20, and in my case specifically the H918 (T-Mobile) but the others are probably similar: This is a list of what I know for a fact and have confirmed: — WiFi: 2.4 GHz and 5 GHz antennas are located inside the TOP bumper of the phone ONLY. — Cell Data: There are RX antennas on both the top and bottom bumpers, and the radio is a “diversity” receiver. A diversity receiver has more than one antenna (in this case 2), and it switches from one to another to get the best signal. It is constantly monitoring the signal quality and strength on each at the same time and uses the best of the two for receive. My To Do list: — Test my theory that the TX (Cell Data) mostly uses the bottom bumper. I suspect that one or more bands may use the top one for TX as well. Figure out for each band (2, 4, 12, 66) if the TX is on the bottom or top. — Determine exactly what each spring loaded terminal on the top and bottom of the phone where it connects to the bumpers is used for. Another words, if one of them is for this band, or that band, or if its combined, etc. I will be using a HACKRF SDR and/or a SDR USB dongle in my quest to figure out the transmit stuff. There is a secret menu that can be accessed if you have Android 8.0 on the phone where you can turn bands on and off. All bands are listed, but the phone will only work on the ones that the carrier allows, even if its unlocked. They blow “fuse bits” in the radio to disable bands that they don’t support. That is why you can use an unlocked phone with another carrier if its the same type of service (CDMA or GSM) and then get horrible data speeds. The voice connection will always fall back to GSM instead of LTE - just a fact I learned the hard way. The secret menu can be accessed from the phone dialer with the following code: 277634#*# You cannot brick your phone with those settings, but you can make it not work properly, or at all. A re-flash using LGUP and a KDZ file will always put the secret settings back to factory default, and of course wipe all your data.

Here’s an image
Can an alloy case around the circumference of the LG V20 cause significant degradation of signal?
It is a sticker right above the earpiece connected with 2 gold points. It boggles my mind how much of this phone relies on gold pads on little stickers for sensors and such.
