Broken gold WiFi tab inside of N7 - Nexus 7 Q&A, Help & Troubleshooting

Ive had the 0% battery issue for the past couple of days, so I started reading multiple threads about the battery not charging issue when I came across @winter128 stating he took the back cover off and noticed the batery cable wasnt even plugged in. I did the same and noticed the exact same thing. Evidently the battery cable does not have any locking mechanism, so it works itself out. While I was pushing the battery cable into the slot, I accidently broke one of the (2) gold tabs that are the WiFi. I put the cover back on, powered up the N7, and now my battery says 100%. WiFi seems to be working just fine also.
Any ideas what this additional tab is for?

arm chairing thus one
if it's for wifi it might be for an external antenna hookup
have you tried to see if nfc is working?

mine broke too
the only difference I took out the other side of the wifi contact. My N7 (8gb) is having the "I don't wanna charge if i'm at 4% or less" issue so I crack it open and do a 'hard' power cycle the battery. IDK if it will have issues yet, it's still charging. If it does I'll sell it and get the 16 or 32.

umm.. antennas work in loops. the two contacts are probably the loop around the back cover.

update #1
I RMA'ed it back to Asus. Wifi sig dropped. I need it to work 90 ft from AP (no solid walls) for work, it didn't. At home it'd work only in the room the AP was in. I'll post the results from Asus repair if they deem I need to pay and how much. Just so ppl know what to look forward too. I informed them I had a "spongy" screen too. So, IDK if that will effect my repair bill.

I have just opened up my nexus 7, I got one for Christmas but noticed the wifi signal being very weak. Tried everything on my router but no luck, so brought a plastic pry tool and opened it up tonight and I notice where the two wifi antennas should be both are missing. There was a s/n sticker just above the where the antenna should be and stuck to the sticker is what I presume is one of the antennas so will be arranging a warranty repair tomorrow

Wi-fi suddenly extremely weak / not working

The Wifi of my HD2 is all of the sudden barely working. It only gets a signal if it's about an inch away from a router, so in practice it's not really working.
I tried several roms and radios, run task 29, but nothing has had any effect.
Do you have any ideas what has happened? Do you think it is hardware-related?
Have you checked in the WIFI settings,there is an option for best performance or best battery.
Yeah, it doesn't seem to change anything.
maybe uve bent the phone and the antennas/antennas solder pad disconnected
Interesting.. I have been pushing the sides of the (somewhat recently replaced) digitizer pretty hard in an attempt to make it fit perfectly, because the service-people apparently didn't do so. Could this have loosened or disconnected something?
Another possibility is of course that the service-people did something, but they claim that's not possible.
Anyone?
(yea, this is a bump of sorts)
WiFi signal extremely weak
I have the same problem with my HD2. I tried changing ROM and/or Radio but nothing happens. This is not my first HD2, i buy them and then sell them here in my country so it is probably a hardware issue. However this is the first HD2 i got that is apparently manufactured after June of this year, which I think is a new model.
Here is a comparison between the HD2 and a Pure, side by side in the same room. (The router is about 3 meters from the devices)

Any other one with a problem like this?
yeah, my HD2 has always got weak WiFi signals, while my laptop shows 4 bars, the HD2 only shows 2 bars. But back then, the WiFi is still usable.
but since last week, I kept getting disconnected from the WiFi router when i try to access the internet. No matter how many different ROMs and Radio i try, they are all the same.
I'm starting to wonder if HTC hardware fails after a certain period of usage... hmm...
Phone was prolly damaged during the repair process, take it back and have them replace it

PiPo M9 drop dead =<

Hey!
I had a PiPo M9 (WiFi) now for about 2-3 weeks and everything worked perfectly.
No problems with rooting and installing ROMS ( i fixed that 2-3 days after i bought it)
I was playing some angry birds yesterday, and all of sudden i had VERY low battery, i put it on charge even if i recently took it from it.
Then i noticed that the DC-connection in my tablet is "loose" , i needed to have the cable in a specific position for make it charge.
Battery was fully charged but it said i had about 16 minutes left, and in 1 minute it dropped to 43% and only had 2 minutes of the battery left...
I tried to calibrate the battery after it was fully charged (i let it charge for almost 10 hours) but there was no difference...
Anyways... i played some games later on and forgot about the position of the cable so the tablet died...It had a bootloop about 6 times and i was trying to put the cable correct for make it charge but i failed and the tablet died.
Now it doesnt react at all, and unfortunally i don't know what the EXACTLY position is for the cable so i have been trying around but without success...
When i am connecting the USB to the computer it doens't react either, and i tried to push in RESET while holding the other buttoms as well, without success...
I Don't know what to do , and i don't know what is wrong?
I opened up my tablet carefully to see if i could see the problem but it is hard to do anything without knowledge about it....
I know that it has something to do with the DC-connection but i can also imagine that it has something to do with the batteries..
If i need to change the batteries , what should i buy? And how should i do? I need a guide, walkthrough ,... i have been googling around , also on youtube, without any luck...
Anyone out there who can help me?
I am kinda desperate.. :/
I solded and fixed the DC-contact, it was loose, but there is a component missing and i am unsure what component it is, so i have a picture and hope someone can help me out....
I'm a little unsure of what component that is missing, but it is backside off the mainboard, just below the dc connection.

[Q] Wifi range terrible, does replaced back effect it?

Hi All!
I bought a N4 off ebay that had its back replaced, here is what the listing said, "This phone has a replacement back glass WITHOUT wireless charging or NFC capabilities." which I dont really care about but my WIFI range and GPS is terrible.
I've tried multiple kernels and roms *including complete stock everything*
Its not my setup as my HTC one s, multiple laptops, wii, ipod, ect,ect all work perfect on my Asus Router rt-n66u.
Does anyone have anything I can try?
Also have a thread up for my gps : http://forum.xda-developers.com/showthread.php?t=2365187
Thanks for reading!
Since the replacement back does not support NFC or wireless charging, do you think it was suitable to support any other wireless feature that was designed for the Nexus 4? Does Bluetooth suffer the same reduced sensitivity? If the replacement back is not made of similar materials withsimilar characteristics as the original back it might be absorbing or reflecting signals, interferring with proper wireless recepton.

Well thats my fear,

Looking at this post it looks like whoever replaced this phones cover didn't transfer over the copper attenna's , that would be my guess and would explain my horrible wifi and GPS ... luckily my phone reception is good.
I'll have to open up my back now and take a look... now to have a T5 screwdriver at work..
Unfortunately cant find a t5 here at work , I'll have to wait till I get home.

Looking at this image looks like I should only be missing the top right 2 antennas for Band 5 , GPS, WLAN, BT. I assume I have the other 2 antenna's as my phone reception is good .
Anyone know where I can buy just the antenna's?

Should I try to save my black screen nexus 4?

Hello people.
I need help to decide if I should try to save my nexus 4 or not. It has been dismantled for the past half a year and i recently got it to show signs of life after battling the steady red ring of death. (Was simple by the way, just used a wireless charger for a couple of minutes) But if I turn it on, it vibrates, the screen lights up and that is just about it. So i have no idea if the phone itself is functional. Some of you might tell me not to bother with such an old phone, hell, they aren't even sold anymore. But this phone has stuck by me through thick and thin, and has a sentimental value. I nearly jumped of joy when it showed signs of life after such a long time. I am not a rich man, so i need to manage my finances. Screen replacement would cost me 25 pounds, back housing would be another 10, but what if the phone is still not functional? Is there any way I can find out if I should take the gamble?
Some info -
I am not entirely sure if there is an OS currently installed on the device, as I was experimenting quite a bit before the battery run its coure.
I am also missing one of the connector things that are circled (there is one and a broken spot where another one should be) but i have no idea what it connects to. The little peg itself is safe and sound in my possession, if it can be welded back. It connects to whatever is under the power button on the back housing.

The screen is cracked in three places, but was working the last time I remember. But there have been many (and I mean many) dis and re assemblies since then.
I probably love this phone more than my friends and family. Just want my favourite piece of tech to be my companion again.
Could the red light be due to a dead battery?

Thankls for the reply. The battery is new and the red light issue is sorted. The phone just doesnt do much more other than vibrate and light up the screen. How do i know if it is still worth investing money in is the real question.

Sprint LG V20 - dead GPS after drop onto concrete - any repair/fix suggestions?

Sprint LS997, refurb bought Oct 2017 via Amazon, non-rooted, Android 8.0.0 for a few months now.
Searched other threads for solutions but could not find anything applicable.
Up until a few weeks ago, everything about this phone worked great. But I dropped it onto concrete sidewalk (basic case didn't do much) where the case and back popped off (battery stayed in though). Later that evening I went to use the GPS but was unresponsive. Did some Googling for possible causes and ended up buying a new top cap (LS997) for a few bucks to see if that would fix it - unfortunately it did not. Tried putting on my original factory back cover (current factory back case has magnet attached) but GPS still dead. All other network stuff work just fine (at least BT and WiFi which is all I use).
So I removed the top cap again to see if any of those tiny springs/contacts were goofed up, and noticed that my phone does not exactly match the one shown in this post:
https://forum.xda-developers.com/showpost.php?p=78264829&postcount=11
If you look at the two contacts on the right side of stevejs's H918, my LS997 only has the (EDIT) contact on the right side - the left one is not there. Could it have been knocked loose from the fall, then when I originally took off the top cap to inspect, that one contact fell out without me noticing? Both my endcaps have the same contacts as shown, so nothing appears to have been dislodged from it. Not sure if another LS997 owner can check their phone to confirm...
Besides buying another phone (V20 or otherwise) to have a working GPS again, any suggestions from this community for a possible repair?
I tried to link steve's image below with my note in yellow (link is to my photo via my Google acct), but not sure it'll display correctly - thus my verbal explanation above of the missing contact.

So...no suggestions?
I remember I used to have a ppc6700. That was one of the original smart phones, probably 18 years ago.
Those didn't have built in GPS. However, I was able to get a Bluetooth GPS for it... Relatively cheap.
Imagine those are still available for sale and that would solve your problem on the cheap. Probably mountable in your car.
Thanks for the reply, though probably won't go that route. If a local repair shop can't diagnose or repair, I'll just buy a NOS V20 from ebay and call it a day.
