I dropped my phone on some tiles and the screen cracked. Phone seemed to be working fine for a few days, but then it got into a reboot loop, as in rebooting again and again within a minute after last reboot. Tried recovery and recovered to another rom just to check, but still same problem. Found out that disabling 3g (only connect to 2g networks, in settings) ended the constant rebooting.
So what I wondered was is there something I can do to fix this? Replacement parts?? Flashing radio? Is there a chance 3g problems is NOT from dropping phone? I have no clue Just not that keen on spending lots of cash on a new phone
Btw, replaced the screen, 3g problem still there. (Knew those probobly werent related, duh )
Well, problem happened after dropping the phone, chances are its hardware. Check the battery cover sinc, and I believe, the antenna is located there and makes contact with that cover.
Sent from a dream.
Phone antenna is down part of cover were is sim and sdcard are. Maybe connectors or antenna or it's hardware problem. If it hardware problem then you maybe have to buy new phone.
I noticed the long antenna to the right of the battery directly above the sd card is torn above the screw all the way threw the tape and antenna. I tried searching to find out witch antenna that is but cannot find anything. The damage pretty much makes the antenna worthless I would imagine. Its only connected from where it is attached to the board to in between the screw and the little rectangle shaped hole above it, so not much use. Im kinda thinking its my WiFi antenna because its been really wonky lately, but could just be my router getting old.
Can I get a replacement, or will Sprint still fix it (I am still paying for the total equipment protection) even though the EVOs are EOL? Since its a hardware issue should I unroot my phone back to stock or will they not mind?
On my HTC Vision/G2, the wifi module seems to be loose inside. If I turn on wifi it just turns itself off after not communicating with the module/antenna. Wrapping the phone on a table seems to fix the problem temporarily. Is there a ribbon cable inside or something that could be breaking down? The wifi module works when it is connected, but after moving the phone it will seemingly lose connection. This is especially annoying because I tether with the phone all the time and usb tethering doesn't work on the android tablet I own (or probably any android device).
If anyone has any ideas, I'd be willing to listen. I don't really want to spend $100 or so to replace this phone right now. Its a little long in the teeth sure, but I'm on the broke side for a few weeks/months here. I was thinking I could take it apart and find what's wrong with it. Just seems to be a bad connection....
I had something simular happen on an old phone and hate to be the bearer of bad news but it ended up being a bad smd part. Maybe try flashing another radio etc and keep your fingers crossed but my experiance was a bad smd chip.
Sent from my G2 running the random rom of the day.
I did a search and most of the Wifi problems seem to describe knox security and bootloader issues.
Here, I wish to describe/discuss what seems to be a hardware problem in my n7100 note 2.
This occurs with stock and dr. ketan rom on 4.4.2 even with wifipatch applied (technically not needed).
OS 4.4.2
boot loader: n7100ZSUFNL1 (I believe this bootloader should be ok - correct me if I'm wrong).
model GT-n7100
ISSUE
- the wifi icon doesn't turn on or wifi drops out when the system is running hot. This happened the first time after I flashed a ROM/upgraded and I thought it was a ROM issue.
- however, more recently, I have managed to keep the wifi signal absolutely stable when i open up the back cover and run a fan blowing on the back/cpu area at the top back of the phone around the camera area.
- with fan cooling => completely stable
- without fan cooling => drops out when system under load or randomly.
for some reason, omega rom had a problem for me where it kept disconnecting irrespective of the heat
I have seen discussions of our phone overheating but this seems to be a hardware problem with the wifi module.
I presume that there may be micro fractures with the wifi chip solder (seems to be a theme in electronics) that may be causing wifi problems with overheating.
This happened with an iphone 4 voice audio processing chip once for me and the "online community" had figured out a fix by taping in a "pressure mount" for the chip.
//blog.lovefone.co.uk/iphone-4-faulty-microphone-audio-chip-problem
Any suggestions on taping in a heatsink or pressure against the wifi module?
Help would be appreciated. Just adding to the knowledgebase in the community.
When Samsung adopted RoHS some range of devices plagued with badly soldered BroadCom chips. I personally know one S3 and two Note 2 (one is mine own) with all the same problem: no WiFi from time to time and likely no BT too.
I paid ~100 euros to change the main board with BC chip guaranteed working about half a year ago.
Thanks for the quick reply and confirmation.
After ordering a new midframe; playing around with screws and disassembling it a few times; it does feel like a solder joint/connection issue.
I haven't heard much feedback from the net on this problem which is why i raised it.
Others on the net have mentioned loosening the screws securing the motherboard down. I will try that as well but I presume that with a loose solder joint; overtightened screws may warp the motherboard just enough for the connection to flake out.
THanks again.
PS - if anyone else has the same problem/suspicion; please chime in.
So, in follow up.
Adding aluminum tape to the wifi chip didn't seem to work. I took it off and reseated the midframe where the antenna is located.
Still was getting dropped wifi.
Disassembled; took a small screwdriver and gently lifted the wifi contacts from the motherboard up so that it makes better contact with the midframe.
Seemed to help.
It's definitely hardware. Whether it's a problem with the WIFI chip or with the antenna; i don't know but it's somewhere along that line.

Hey guys,
I have a problem with my OP3. I dropped it and it had a big dent on the back. So I decided to open it an try to press the dent back into shape.
After reassembling my Wifi and bluetooth are broken. I can get connections but the range is realy bad, about 5m for Wifi till it disconnects and about 5cm for Bluetooth.
I opened it a second time to take a look if i missed a connector or something and i saw a clip (those small things that connect to the back of the phone) was broken so i ordered a sparepart (it was the headphonejack circuit board) and changed it but its still not working.
Does anyone know where the bluetooth and wifi antenna are positioned ?
Have i just broke my phone or can i change something to get it back to work ? Everything else is working fine.
Thanks in advanced
Dennis
Same problem here! After I replaced the screen I lost my WiFi and bluetooth connections as well. WiFi is working in a range within 2m.
Is changing the coax antenna cable a solution?
Many thanks in advance from me as wel
Ken
Glad I'm not the only one, so maybe we get more help when more people have the same problem.
I changed the backplate cause of the dent and because the antenna is built in there but didn't change anything.
I have ordered a coax cable and will replace it when it arrives, could be today. Will post afterwards if this helped, but I'm not realy confident in that because i haven't done anything with this cable while repairing.
Maybe someone knows more about this, i just don't get why it is working but has no range, makes no sense to me ...
I have opened my phone several times now, but nothing seems to work.
Do you have an update on the coax cable yet? I hope it works, or the one plus 5 has to hurry ?
Hey there, same for me, opened it up to 10 times now but nothing helped, coax cable was a failure too. I realy don't know what it could be.
I'm about to wait for the OP5 or get a used 3(T) depending on what the . Was thinking about getting one with cracked screen and change everything but not sure if i should try it.
I have the same problem now. Any updates?
Hi guys! Yesterday I changed the camera of my OnePlus 3 because it wasn't focusing anymore, after reassembling my phone I noticed it wasn't connecting to the wifi anymore, tried Bluetooth and it was the same problem... I had to be really close for it to connect
Did any of you had any luck solving this problem? Did changing the board in the bottom of the phone not solve it? It seems that's where the WiFi is... Or maybe changing the backplate
Thanks in advance!

i also have same problem , need fix
Anyone found a solution? I had the same problem when I replaced the fingerprint sensor + the battery
I've been without wifi for 4 months now... Any help is appreciated
Hi, guys. I have the same problem. Did anyone find a solution?
I replaced my rear camera and the loudspeaker, at reboot wifi was not working. I noticed that if I'm near the access point network is detected but with very poor signal strength. Thanks.
Hi, maybe I could have found a possible reason to our lack of wifi and bluetooth signal.
Please look at this thread and give me your opinion. Probably your mainboard shows the same problem.
