Need help with my G-sensor - Touch Pro, Fuze General

Hey guys/gals, I need someone with hardware knowledge. I've been working with my Fuze for a long time and I pretty much have a handle on everything, well almost. My Fuze had a tragic run in with some rain. I was able to get almost everything to work again after complete disassembly and drying. I know, I was as shocked as you all are! Anyway, as you can see from the title, my g-sensor is the only thing not responding. I'm not afraid to dive into my phone if it's something I can repair, but is it a module on the phone? If so, where? I have the manuals but they state nothing about the g-sensor location. I've tried the calibration, but nothing. Anyone have any ideas? Also, I have a thread in the marketplace, looking for a speaker/ringer for the phone. While reassembling, the wire got pinched. Thanks guys, as always.

same problem with me. gsensor is broken. cheiefs please give some clue on repairing.

The same problem here.., any solution or fix??, why this happend???

lets try to find something common that might be the reason. I will try o write some possible reasons :
1- did you drop the phone recently ?
2- do you use a car phone holder with magnet ?
3- did you left the phone to direct sunlight?

I would guess being submerged in water is what caused it as it says this in the first message.....

Screen damaged...Need to flash ATT SPL!!

I flashed the HTC factory rom a few weeks back, and now (not because of the flashing) my screen is broken. I think I sweat on it and it has caused the connectors to be intermitent. The water damage sticker is luckily still white I have alreay flashed the ATT stock back onto the unit, but without screen viewability, I can't run KAIS-SPL. You can here the ATT swoosh sounds on startup. The screen works about 5% of the time, so do I chance sending it back with HardSPL still on it as they might not be able to verify. The 5% chance scares me. Is it possible to put ATT SPL without having the screen work? Lastly, is there a command line interface to remotely activate KAIS-SPL?
Thanks,
brux2dc
FYI. This unit is still within the 30 days, but i am sure they will check it before issuing a credit.
get it replaced. try in store first since you're within ur 30 days.
if you need to go through warr exchange, have no fear. ive sent back 6 kaisers lol
one had a chunk missing outta the corner. another, the pixels went green and wack. another had a replaced screen and that screen had an "oil" spot and the hinge was all loose. no fees.
the only thing i would worry about is them replacing the screen and seeing salt from your sweat. even water leaves a green residue at times on electronics.
oh, and if you dont wanna do that, you can grab a refurb from ATT or another seller for cheap. all my refurbs were lnib
Yeah, I bought mine over the internet through the FAN site. Unfortunately It would be easy to show the clerk in a store how messed up this phone is. I"ll just send it without worrying about the SPL. I haven't seen the screen all day, so I guess it is FUBAR!
6 phones? Is this phone really that crappy quality wise? Should I get a different phone. Although this phone has everything I could want in a phone (for the time being )
Thanks

This phone is NOT CRAPPY (except the video DRIVERS).
It actually depends on people's use. I personally keep my phones away from all the hazards and on cases (leather, silicone...) If anything happens to it its just BADLUCK.
My opinion is If you are happy with your phone then do not get a different one.
This would work, if you could install it...
There is a program that might help you, SOTI pocket controller pro. It will let you control your phone from the computer... the only problem is installing it. You would need to be able to hit the check box. It might be possible to have it installed automatically with UC, but another, more knowledgeable member would need to give advice for this one.
If you do get the program on your phone, you should be able to revert it to factory. As another post already said, you may be fine anyway as I doubt a new phone under warranty will be heavily scrutinized by ATT.

this is false, when i freshly flash a new device and it dont have soti installed then i just open soti on the computer and hit connect. It then installs the cab with no prompts. SOTI would work very well in this instance!
wow 6 phones, and here i'm getting mad about 4, i'm still waiting for att to send me one that works, i guess my 4 isn't that bad at all.
and at op sogun is correct, SOTI works great used it to take the contacts off my hermes when the screen broke. but i took that phone apart to the mother board and did it that way cause i couldn't remember how to put it back together
thanks for the help.
I'll look into SOTI.

[Q] Is it safe to keep my phone right next to or on top of my computer?

Is it safe to keep my Samsung Vibrant right next to or on top of my computer? it's a pretty convenient location
edit: safe for my phone*
I dont think so, that your computer make a damage if you put your Mobile on the top of your computer. My phone is always on my desk to be controlled if i got sms, phone calls etc.

I dont think so
I don't think there's any problems with it, unless your phone has some crazy vibrations lol
There doesn't seem to be any evidence either way, which should mean there can't be a problem with it (because if there was a problem with it, it would have been noticed by now, and studied or at least posted on a site somewhere)
I've had my phones on my PC for a long time, and had no troubles with it. It doesn't cause any heat because it's near the top, and the vibration barely moves it. Only problem is if I drop it or hit it from the PC myself
Edit: Forgot to mention, while looking I found this interesting link

Im nervous about getting mine to close to the router with wifi on. I don't like the antennas that close together. At the power levels were talking about I'm sure I'm just being paranoid but when I was running a bunch of ham radios I learned about something called front end overload. This is when a strong transmitter being to close to a receiver overloads the receiver's circuitry. Keep in mind I have never heard of this being a problem for anyone and maybe I'm thinking too much.
The links was funny, biological virus?

Hi!
If you are reading this now, you are probably one of the unlucky fellows who's WiFi (and Bluetooth) stopped functioning, and if so, you are probably deperately searching for a solution/fix. I might have something for you, but first:
*** DISCLAIMER/WARNING ***
You yourself are exclusively responsible for whatever may (or may not) happen to your mobile device, to yourself or others. I am only giving hints/advices here that *MAY* help, but I will not take any responsability, nor will I provide any support, in absolutely *ANY CASE*, including, but not limited to: your problem not being solved or/and your mobile device becoming partially or completely broken. Let me be very clear: If you do anything to your device rendering it useless, destroying it, seriously or fataly injuring you or others, and then come blaming me or/and cry for help, I will point my index finger at you and laugh at you. Period.
If you are a impatient person and want to get straight to the point, jump right to section 6.

0. Foreword
Two or three months ago, one fine morning, the WiFi/BT of my LG G2 suddenly stopped working. Initially I thought this would be only one stupid annoying minor thingy, that I’d be able to solve it fast. I was wrong.
1. Description of the problem
When turning on the WiFi, it would just stay in "Turning on..." forever. Similar thing for Bluetooth: It would stay on for a few seconds and then turn itself off again after. (But then, who needs Bluetooth anyway, WiFi ist probably 100 times more important...). I have thoroughly searched the internet, and I found quite some videos with exactly the same problem (remove the two blanks from the links to watch):

h ttps://w ww.youtube.com/watch?v=4W8YJMDFM88
h ttp://w ww.dailymotion.com/video/x2cuyjt_nexus-5-turning-wifi-on-frozen-problem_tech
2. Urgent advice
I want to prevent you from wasting countless hours searching for a solution - I wasted so much of my time already, no need for you to repeat that. Therefore: *Please* be aware that there is a VERY HIGH PROBABILITY that this issue is being caused by a hardware defect. I can not speak for all devices of course, but keep in mind that the main reason I wasted so much time, was me beliving it was some software issue! See the next section for a glimpse of stuff I have tried without any success:
3. Things that *DIDN'T* work
01. Restarting WiFi/Bluetooth several times
02. Rebooting the phone
03. Turning airplane mode on/off several times
04. Slapping/hitting the phone (this was indeed suggested in a forum)
05. Using WiFi-Fixer apps
06. Resetting to factory settings
07. Upgrading to newest Android version
08. Fully drained the battery and left it uncharged for several hours
(Rooted the phone)
09. Deleting the /data/misc/wifi/wpa_supplicant.conf
10. Deleting the whole /data/misc/wifi folder
11. Creating a file named ".bdaddr" in /persist/bluetooth containing a MAC-Address in hexadecimal format
12. Creating a file named ".macaddr" in /persist/wifi containing a MAC-Address in hexadecimal format
13. Flashing several custom ROMs to it (CyanogenMod, ParanoidAndroid, ...)
14. Going back to stock ROM
15. etc. etc. etc.
16. Several combinations and permutations of the above
4. There is little hope
Again, as the cause of the problem is most likely a hardware issue, I don't recommend going through all the steps as described in the previous section; however, though none of the steps worked for me, this doesn't mean that none won't work for you neither; you might be luckier than I was. In that case, enjoy your restored WiFi and be happy.
5. My most obvious advice
You need to replace the motherboard (main board) of your device.
Honestly, if you can afford it and it doesn't cause too many inconveniences to you, you'll be better off by simply buying a new device. If you don't want to buy a new device, send it in for repairs. If you don't want to do that as well, you'll have to fallback to a DIY solution:
I. Buy a new main board for your device. Be careful to get exactly the right component for your specific model. If you dont find any shop selling those, there are plenty of individuals out there that own devices with broken displays. You dont need the displays, you need the motherboard. Buy one such broken device, and you'll have your main board replacement.
II. Replace your main board or let someone else do it for you
Continues below.
continuation
6. LET'S GET SERIOUS!
If you are reading this, you either didn't read or you decided not to follow my most obvious advice in section 5. So be it. If you want to carry on from here, be sure to re-read my disclaimer at the top of my post.
There are 3 DIY possible fixes for the WiFi problem - none is guaranteed. I will describe them from the most harmless to the most kamikaze/deadliest. All of them will require you to open your device; if you are not careful and damage any of the components inside, you will end up with a worse device than before - but hey, don't say I didn't warn you.
At this point we assume that the cause of the problem is a faulty solder joint of your WiFi IC. The goal is to try to restore that solder joint. To do that, you will have to:
I. Open your device
II. Find your main board and separate it from all connected plugs
III. Find / identify the WiFi IC chip on the main board. I recommend searching for a service manual for your device, or/and searching for a disassembly video for your device; you need to know which one of the chips on the main board is the WiFi one.
Once you have identified your WiFi chip, you have 3 options, which you may combine with each other, but I recommend to try them out one-by-one as follows:
6.a Sellotape / Scotch tape
You need to make sure that your WiFi chip is pressed against the main board (ideally, this ensures the broken contacts touch each other, solving the problem). The best way to achieve this, is to attach a series of tape strips on the top of the WiFi chip, causing it to be pressed against the main board by the surrounding cover/hull once you reassemble/close the device. The tape strips are just a suggestion, do whatever you find convenient as long as you ensure that the chip is pushed against the board at all times.
This method may solve the WiFi problem already. When you turn your device back on, give it some time (5-10 minutes) and reboot it a few times if the problem still persists. My own WiFi didn't function right away, but after a while it finally recovered - hurray!
6.b Refrigerator / Freezer
Instead of using the tape as described in 6.a, you may first try to put your motherboard in a fridge for a few hours/days. But make sure to put it there in a plastic bag, and avoid moisture as much as you can, specially when taking it out of the fridge. Make sure its completely dry before reassembling your device!
By the way, try the refrigerator option BEFORE you try the freezer option!
6.c Oven
If everything else fails, the oven might be your last chance. This is not a joke, but as you probably can assume, it is "All-In" i.e. highly risky. The theory behind this is that high temperature will cause defective solder joints to reflow, reconnecting and thus fixing the problem.
You should only try this as a matter of last ressort. Be warned that you may fully destroy your main board, and there is a high chance that you will. Also, you may cause serious injury to yourself or others. Make sure you make backups of your data first. DO NOT BAKE THE WHOLE DEVICE, ONLY THE MAIN BOARD. DO NOT BAKE THE BATTERY!!
If you are still reading:
I. pre-heat your oven to 385° Fahrenheit (196° Celsius)
II. put your main board in the oven, bake it there for 7 minutes
III. remove from the oven, let it cool down until every component of the board has room temperature
Finally, here is a video of a guy doing a similar thing, but with a heat gun:

Ok, this is all, I hope I could help you.
Good luck!
Summary
Hello all,
first of all, I want to thank brysclar and xbing6 for their valuable feedback! Thanks a lot guys! :good:
Now, in an effort to update this thread and in an effort of trying to summarize it in fewer words (my disclaimer above applies!):
- The described problem seems to affect mainly (all kinds of) LG devices
- The issue seems to be caused by a defective soldering of the Wi-Fi chip on the main board
- The defect seems to be induced by dropping or/and overheating the device; recharging the battery, big/long app or android updates or the flashing of custom roms could cause excessive heating
- brysclar pointed out that replacing the battery might solve the problem (I haven't tried this out myself, so I can neither deny nor confirm this)
- My recommended solution is 6.a - applying pressure on the Wi-Fi chip, pushing it against the main board, using tape stripes
- There is a video of a brasilean guy doing some similar, but using pieces of an old credit card instead of tape strips: https://www.youtube.com/watch?v=OJkdva2iOag BUT PLEASE NOTE THAT HE IS APPLYING THE PRESSURE ON A RANDOM SPOT, NOT DIRECTLY TO THE WIFI CHIP! It *may* work for you, but if it doesn't, find/identify your Wi-Fi chip and apply the pressure there
- If everything else fails, and only as a matter of last ressort, you may try what I have written in 6.c
So... this thread has over 500 views, but not one single reply.
Guys... what has your experience been? Have you tried anything out from the posts above, and if so, what was the result? Did it help you? Do you recommend anything? Has something else, not written here, worked for you?
There are a lot of people out there having the same problem. It would be great if you could give any feedback, share anything that helps the community.

I honestly didn't see this post before. You really covered every detail very well. So far, returning my G3 to stock and replacing the battery has fixed it for me. Weird. I know. I did try 90% of the things on your "things that don't work" list and you are correct. They don't work.
wlanmac 02/00/00/00/00, Bluetooth is OK
Hey, i just got an LG LS990 with same Wifi issue and i'm ready to try so WITNESS ME!
Thanks for an amazing and detailed post lml
Simply awesome.
I have similar issue with my Nexus 5x. It is QCA6174 hw 3.2 chip, lspci does not detect this chip any more. I am going to do a little bit investigation from device driver (cnss) perspective. It enables one GPIO to provide power to this WiFi chip, I will try read back this GPIO status to see if it is enabled. I do not have the schematics, I do not know how to check if power is supplied to this wifi chip.
lspci used to show below:
$ ./lspci
00:00.0 PCI bridge: Airgo Networks Inc Device 0300 (rev ff)
01:00.0 Network controller: Atheros Communications Inc. Device 003e (rev ff) (this is qca6174)
If kernel driver investigation does not reveal anything helpful, I will ask other guys to replace the chip.
I thought it is because of vendor partition is accidentally wiped out, maybe it is unlikely.
---------- Post added at 08:49 PM ---------- Previous post was at 08:40 PM ----------
As Bluetooth can not be turned either, I am tending to think this is hardware related as well. As described previously, I will see if I can check that gpio status.

Hi xbing, and thank you for your feedback! :good:
I am really curious and looking forward to hear the results of your investigation! I believe that in your case, too, the Wi-Fi/BT chip is not being supplied correctly due to a defective soldering. Note that I don't think that the chip itself is defective, only the contacts between the chip and the main board. So, before replacing the chip, I'd recommend to first try what I've written in 6.a (or check my update/summary above).
Keep us posted about everything you find out!
Sprint declined to fix my LS990 due to "water damage" being the reason for it not working, and wanted to charge me a $150 deductible for a $100 phone. Shimming the WiFi chip against the metal covering with some thermal pad I had lying around and adding a bit of sticky foam on top of the ribbon cable for the camera worked great! Much thanks!

Hi NavHur,
since the problem is mostly caused by a loose Wi-Fi chip, respectively a defective solder joint, using thermal paste or grease is unlikely to help; again, what you need to do is to have your Wi-Fi chip pushed against your main board. You can use your imagination on how to accomplish this; what Tomcat5 described he did ultimately led to exactly having his chip being pressed against the board.
Of course you are free to try whatever you want - if you find new solutions please post some feedback.
Good luck.

Thanks you so much, I placed a small piece of plastic above the wifi chip and one next to the camera lens. Now the wifi works fine. However my screen was pushed up so it bended a little. The faulty thing was my battery, not the added plastic. I compared mine with the one of a friend, mine was 1 mm bigger. (also with the battery of my friend's g3 the screen was fine)
I'll be changing it soon.
same problem as u but sometimes wifi works(mainly fully charged) and sometimes dont

Hi Pratap94,
nobody, neither here in this forum nor elsewhere in the internet, will be able to give you a reliable answer without having a *physical* look at your phone. Nobody.
However, I can give you my opinion, based on the stuff you wrote: The fact that it works normally sometimes, specially while charging (probably it heats up in the process?), indeed seems to indicate a hardware issue. I believe you have a loose Wi-Fi chip i.e. a defective solder joint, like I had on my LG G2 D802 as well. I solved my problem by doing the stuff I described in 6.a.
Good luck.
Thank you so much

Hi Olzhas18,
that might be an indication that your WiFi chip is still a bit loose and is not sitting tight enough on the main board. On LG G2, it is difficult to push the chip against the board because it's covered by a metal cover...
Also, did you check out this video: https://www.youtube.com/watch?v=OJkdva2iOag ?

Thank you this tip and this whole thread. I have seen this video, but still the same effect. 5-10 minutes, I can rean some news and back to flashing. I'm going to buy Huawei Honor 8 soon, it was the last chance to recover my G4. I doubt I will purchase any other phone from LG.

But bluetooth working
In cm roms also wifi tethring can be onn
But u cnt turn onn wifi
I had the same issue, can't turn on Wifi after factory reset.
I turn off my device off after one hour and reboot wifi was OK but when I want to upgrade some apps iwifi turn of again and my phone reboot with no SIM card.

I have a problem with my flip camera on ZenFone 6, anyone kindly look into this and

The more frustrating issue im facing is, sometimes, (not all thr time) camera's reverse rotation is not fully occuring and stops still little out side the housing at the same time the camera module is loose enough to go inside the housing and comes out little bit when the phone faced downwards in the air.
If anyone has the same problem, please let me know
EDIT: my phone is running on latest firmware
There is a calibration tool in Settings. It may fix your problem.

No problem here.
Check if your Flip Camera and its metal dock is clean.
Calibrate Flip Camera and check functionality.
Service it.
I also have a problem
The camera thinks something is blocking it when i try a fast flip even if nothing is there and says impossible to flip. Sometimes it works.
I cannot calibrate it because of this problem
And it seems clean.
If i drive the camera manually it works but i can see the beginning of switch is a bit hard.
Retracting camera always works well.
All ideas are good to try

Go to system settings>display, see if you have a setting called "Accidental Touch Protection" and if it is enabled. That feature could be activating and then freezing the screen when you try to turn it back on.

Hi there! What was the answer or Solution by technicians? Did they solved the problem?
Hi all there! As I see this issue is the same that A52 has. It's a typical factory problem that could be solved charging the main flex. That's the definitive Solution !
I have the same problem with my A72 (A725f)XID
Any solutions
I tried downgrading it didn't help
Changing the screen of flex also doesn't help
So it's a software problem
But any solutions???
I have the same problem. It seems that all A72 series are affected by this problem. The flex cable appears to be problematic. Almost every Samsung product I purchased had issues. So, never again Samsung.
Sorry for late reply for all questions above. My A72 was not even a year old it was sended to numerous shops from Samsung to the cheap Pakistani shops and it is Un repairable they said that there might Me a chance to repair it if I replace the main board but to find one is very scarce and a new one is almost the price of a new device.
To me personally I will never get a Samsung again my next upgrade will be Huawei,Google pixel or a Xiaomi or anything else I do think that the better devices like Samsung galaxy S22,S21FE and Z fold won't have problems like the A72 or A52 or there was just a big bach of manufacturing that went wrong.
But do let me know if you guys got it fixed in any way maybe I can have a try to fix mine then but to replace part for part and hope that it will be fixed is a expensive route to go.
No just make sure your next samsung is from the European or North /South american market
Then you won't have no issues
I use The A53 & A52s 5G now & i don't have problems

I ordered a new main flat cable, and it was supposed to be delivered yesterday, but stupid NordPost in Norway did not deliver it in time. So, I must wait until Monday or Tuesday to get it. Basically, my phone has been opened and lying since Wednesday. I will update you, when I replace the cable. In any case, original main cable in Norway is very inexpensive. It cost me 110 nok or 11 euros.

My A72 is from Europe. It seems it doesn't matter where it's from. All A72 models are effected with this problem.

You are lucky it is not expensive here in South Africa every thing is expensive if I take a guess it will be around R400, my phone acted actually weird because it started to have unresponsive screen restarted the device then will work for a few seconds then will have the same problem, sometimes my network signal will totally disappear and there will be two round sircles, sometimes when I charge my device it will show the phone is overheating even though the device was not even on for a while other times it will show the charging port is wet I can't think that the flex cable will cause all that problems
