My HTC Universal says the SIM Card cannot be found or is missing, which of course is not true. I have tried with several SIM-Cards, but none of them work better. The error message appears as follows: Sometimes the phone connects to the network, but then suddenly the connection is cut off.
I bought a second-hand device, but before I jump to any conclusions I would like to rule out whether:
-it could be related to a radio upgrade
-it could be related to the SIM-Lock removal
-it could be related to a ROM-Upgrade
I am using Radio 1.18 and maxstegi's ROM 4.7.
Besides, I would like to know where to fix the device. It was originally a T-Mobile MDA Pro, but now that their software isn't any longer installed, they would probably refuse.
Thanks in advance

I had the same problem with mine. I eventually solved it by playing a hot-air rework blower over the radio chips, It's a bit of a drastic job, but it worked for me.

i had the same problem .. and i tried another solution .. i got a dry magnetic head spray cleaner and i sprayed the whole mother board connectors .. it worked as a start with me and i am waiting if it will remain good or will happen again ..
3 days now and my xda didn't give the sim card message - my problem solved
Great idea. I'll try today!
Sorry..but..for "dry", what do you mean? Is it the isopropyl alcohol based liquid?
i mean dry that it does not leave any traces on sprayed place after a while .. some other magnetic cleaner sprays leaves an oil layer over the sprayed area ..
ask in your location for a magnetic head spray cleaner and i am sure you can found one easily
it is now about 1 week and i had no problems
thanks

I also suffered with sim card problem and got the solutions please check your PMs, sent you the web address to download it, have used it myself, works good.

Hi aym_louis "big mind"!
Yesterday I immediately went to buy the spray "deoxide for contacts" instead of "magnetic heads cleaner". It was not the kind that also protect the contacts, so it doesn't leave the oil layer on them.
Well...I opened the mda pro, sprayed all over the motherboard and waited for 20 mins. I inserted the sim and didn't work....at first!
I tried after some more time, and it worked, and kept working 'till now...thing that never happened before! Maybe it needed more time to deoxidate the mysterious contacts.
Really good idea! You solved a big problem, in a easier and more secure way, compared to the hot hair flow!
Weeel done!
thanks dear .. any time

Yes problem solved
Hey Guys,
I also have this problem for a long time and I'm using another device now..
to summarize:
1. I need a magnetic head cleaner? not contact cleaner?
2. Which chip should I spray? on which side of the MB?
3. Should I go the "hot air blower" route at all?
It's a really annoying problem!
Thanks,
Ariel

I've got the same problem, and I've tried yuor solution but it doesn't work for me.
I've used a dry magnetic head spray cleaner on the motherbord (front and back) but the problem is the same ..Sometimes SIM Card is missing..
I noticed that if the settings of the phone (Band) I force GSM (not Auto) error occurs less frequently..
any Idea?
It worked great!!!
Just tried the dry magnetic head cleaner spray and all I can say is it WORKED GREAT on my Uni, which was displaying that «Invalid or missing SIM card» annoying message!!!
I disassembled the unit completely (this included removing all the inner metallic "shields" fitted to both sides of the mainboard), sprayed the mainboard on both sides repeatedly and quite abundantly and allowed it to dry for an hour.
On the first reboots it kept getting stuck on the 1st splash screen, so I waited for another hour, for it do dry completely.
I then performed a hard reset on the Uni(t).
It simply worked. My SIM card is now recognized again.
I'm on my 4th reboot since I've reassembled it and the OS loads completely, I've reinstalled the software applications I lost after the hard reset and my SIM card keeps being recognized by the Uni and allowing me to make / receive phone calls & text messages.
Thanks a lot for the hint.

Hi Guys,
For what it's worth i have exactly the same problem on my G3 device. I used Servisol Video 40 from www.maplin.co.uk which is a tape head/disc drive cleaner, and it says on the can that it "removes tape oxides and dirt". I removed the shields around all the qualcomm chips and covered the MB, let it dry in sunlight (took 10 mins), reassembled and the problem is still exactly the same, i.e. this method DID NOT work.
For those of you who DID get this to work it would be very useful to know EXACTLY what cleaner you used.
It would also be helpful to know how 'permanent' the fix was, and if anyone else has tried what I have and succeeded or failed?
Many thanks for the helpful posts, if I can get this solution to work it would be awesome. If not then it's onto the rework station and who knows what then.
Cheers,
Appy
I am suffering from the exact same problem; can those of you who fixed this horrendous issue by spraying your motherboards, could you please confirm that your devices are still free of that "missing sim card" error. And what brand of spray did you guys use? If at all it makes a difference.
Thank you.
I cannot find anything in stores remotely similar to "dry magnetic heads cleaner spray" if you guys know the brand name of this product or an alternative, please post your replies.
Your help is greatly appreciated!
found contact/head cleaner at the source; sprayed once then tested, it didn't work. Sprayed second time then tested, it didn't work either but managed to keep the phone alive without loosing the sim for a few hours. I guess will be spraying the third time in a few days...
If anyone has any suggestions please feel free to share.

Problem
My Galaxy S think it is connected to a charger all the time, and as a result of this I cannot see how much battery i have left. Neither can I boot the phone without having it in a charger, and sometimes when I connect to a wall-charger it opens kies on the phone.
While the phone is turned on it does not detect either the USB to PC cable nor the wall charger. I am still able to flash, and I have tried some different roms, but the result is the same so far.
How may i fix this?

SOLUTION
Step 1.
You need a few items to clean the usb port on your Galaxy S devise:
-A needle wich is small enough to fit in the usb port on your device (you need it for wrapping paper around it, so it has to be a thin needle)
-Methylated spirits/denatured alcohol, if you don't know what it is, use google to find a translation (this is needed to remove fat which is stuck in the usb port)
-A tiny brush of some sort, and this is the brush I used (this seemed to remove the dirt, while the other things just loosened it)
-Toilet paper, or some other kind of paper which you can wrap around the needle
if you don't have these items, you may find improvise and find something similar
Click to expand...
Click to collapse
Step 2
###Turn of the phone and remove the battery!###
Step 3
Tear a small piece of paper wrap it around the tip of the needle, and then dip it in the denatured alcohol. Now use carefully clean inside the usb port with the soaked paper and use the needle to move it around. Clean it for a bit, and when you're finished make sure there is no paper left in the usb port.
Step 4
Now clean the usb port with the brush, and be careful. Make sure you don't leave anything (hair, dust etc.) in there.
Step 5
Repeat step 3 and 4 at least one time.
Step 6
Put the battery back in and try to turn on your phone. If the problem is fixed, then congratulations to you If you still have this problem try repeating the process again, as you may not have cleaned the usb port proberly.
If this solution does not work for you after several tries, you're terrible at cleaning! ...or you may have another problem than a dirty usb port.

Frequently Asked Questions
Why did this happen?
You may not have closed the lid on the usb port, and dirt and fat get stuck in there (you may not even see it). Especially fat or liquids may conduct electricity.
The Galaxy S constantly sends small electric charges to the usb, and if the electricity is conducted it will make the device think it is connected. As fat, liquids and other types of dirt may conduct electricity, the Galaxy S is "fooled" into behaving like it is connected.
This did not solve the problem. What to do?
Ask the forums of course! If they can't help you, than send your phone in for repairs. Depending on your country and the source of the problem this may or may not be done free of charge.
In Norway (where I am from) this should be free of charge according to the law, if the cause of the problem is not self inflicted.
Some people may have some kind om insurance which usually can be used in this situation as well.
Other possible problems you should check out
-Your usb port may be damaged and have loose connections (jiggle it a little to see if it works better)
-You may have a software problem with your current rom/kernel/mod (try re-flashing to solve the problem)
I don't have a Galaxy S phone, but I have the same problem
You should try this as well. Many phones connect to chargers or usb cables in the same way as the Galaxy S does.
I don't have any of these items you used to clean the usb port with, what should I do?
You should consider buying these items anyway. You may need them for other uses Anyways, it is worth a try. It may save you time and/or money.
has the phone always been like this since you had it ?? if you have re flashed and tried various solutions, then it could be a hardware fault. possible with the usb/charging port on the phone.. you could try flashing back to stock with all 3 files and pit and re-partition, then if that doesnt work at least you can send it back to samsung with all original firmware on it... and cannot accuse you of doing it by modding the software.

it hasn't always been like that, but for the last week or so. the question is: what is the stock firmware??
I bought the phone in August, in Norway (telenor)
so ur running the stock firmware now ?? that is strange.
why dont you try reflashing the firmware your currently running with the 3 files and pit.
i never heard such thing but il have a look about for some answers now.

oh, sorry! there was a typo, so you may have misunderstood. I have not been running the stock firmware.
I have now flashed with i9000xwjg3, which I think may have been the stock firmware (but I am not really sure). Still the same problem though...
Pit: 512
PDA: CODE_I9000XWJG3
Phone: MODEM_I9000XXJG1.tar
CSC: CSC_I9000XEEJP4 (which i believe is the CSC for norway)
thats really weird. normally after a reflash especially with stock and pit, it restores the phone to like new, so if the problem is still there i can only assume its a hardware fault, and its best to send back to samsung, or where ever u got it from.
Someone correct me if im wrong ???

try scrape any dirt out with a sewing needle, a good lung full of air and a squashed up cotton wool ear bud.
This happened to my device. I eventually had to take it in to be repaired. I asked what they fixed and they told me that they replaced the mother board. Note. My phone may have been a phone with am internal sd problem.

Had this happened to me. It was the usb connection. I put in the plug and jiggle it a bit and eventually it was back to normal. I think one of the connections got loose or something.
Now I'm very careful when I have usb plugged in.
After cleaning the usb-port with alcohol, cotton whool, a special toothpick with a bruhs on it and a sewing needle i managed after several tries to get it working, and imidietly flashed back to darkys rom again without any usb issues....lovely
I can finally use my phone again
Thank you...
PS. I will posr a "how to" later which describes how i cleaned the usb port so that other people may fix the phone themselves if they suddenly bump into the same problem I jusr had

Just had the same problem, thought it was firmware related flashed a couple or roms unsuccessfully then i gave up and sent it to samsung for repair.. the service guy told me that my usb socket was rusted from water contact and they took the phone in for repair.. so i guess thats where the problem lies.. unfortunately just found out about this thread after i sent my phone.

Hello guys, my touchscreen going crazy whenever I'm charging the phone.
Doesn't receive input half of the time. No matter which charger / rom / kernel I try with, problem still there.
The weird thing is, it doesn't happens whenever I'm in TWRP.
Anybody knows the problem? making me charge the phone only at night...

I'm betting that your digitizer is going bad - mine did similar things, then parts of the touch screen stopped responding - had to reset the touch screen several times (cat /sys/devices/virtual/input/lge_touch/f54 seemed to work for some duration of time). I eventually (as of yesterday) replaced the LCD/digitizer and it now works correctly (apart from the fact that I screwed up the new screen, that is).
I would try to open back cover and attach digitizer connector cable properly (next to Jack connector). This worked for me, when I had same problem

Do you have a tutorial? how does it looks? (the digitzer connector). If not, can you shoot one for me? it would be great, because i'm not an expert

Ive attached the image. on the black shield, i added extra tape to hold digitizer connector in place. Firstly make sure that connector is pressed in place properly.
I also glued down the left end of mainboard, so it couldnt wiggle anymore. Hope this helps... Id did for me!
well..... tried it... didn't help :/ but... here's one thing that looks weird to me: when i'm on jb - no problems. when i'm up to kitkat - the problem is back

So after weeks of trying to figure this out I've found what's causing the problem. Not sure how to fix it. When the phone stays on the charger the rotate will stay on. If your rotating stopped before plugging your phone or the charger then simply plug in ur charger and then restart and once ur charger stays plugged in then it should auto rotate some people my need to restart more than once. So in my view I'm thinking there is some electrical problem or lack of power or some how it's linked to the USB port. Please try it and report if u get the same result. Hopefully this will lead to someone finding a solution. Maybe someone can change their USB port and let us know if that solved the problem.

most of auto rotation become malfunction is because lib file missing. especially if u're in custom rom or stock but doing some debloat.
check in your system/lib folder for file libgnustl_shared.so.
if missing, then auto rotate will not work. but in your case maybe hardware/sensor related problem.

It would seem like hardware because the file is there.

Ok. So I can say for sure my rotation issue is related to the usb port. At the begining when I plugged in the usb cable and restarted my phone the rotation would continue working until I removed the usb cable and even for a few minutes after removing it would still work
So what I did was get a very small piece of paper and made it into a little ball and push it under the contact of the usb port right up to the back so that the usb cable could still fit properly. The paper is just to brace the usb connection upwards a little and in doing do so my phone even charging better seeing I had charging issues so I guess it's part of the issue. Now I have normal rotation for weeks.
If rotation stops it's because the usb cable has crushed the paper too small so I just replace the paper but so far it's all good. I just dnt have the interest to do a usb port change but I think that would be a more permanent solve. Hope this helps. Just sharing my experience to those of you who have the same issue and can't find a fix.

OK guys sad to say I'm bk on this because after awhile my rotation stopped again. I don't know if the replacement USB port is going bad again as it was a Used USB port or its something else but I have found another fix which seems to be working a few days now.
So this fix will require disassembling your phone again.
What I did was disassemble my device and when I reached to the main board I used a little screw driver to pry off the shine piece of covering that covers some of the chips which includes the gyroscope chip. U guys can google to see where the chip that controls the gyroscope is on your s5.
Then I folded a piece of tape and placed it on top of the gyroscope chip just thick enough so the metal covering when place back on it will squeeze the tape down on the chip. After all that is done reassemble ur device and try it out.
On a side not my proximity sensor was not working properly either and I did the same thing. Folded a piece of tape and place it behind the proximity sensor it will be tight again when phone is reassembled. So far its been working for me so I hope this helps.
I know its an old device and most of u might not see the need to fix a device this old but for those of you who like tinkering with ur device like myself u should try and let me know if it works for u.
HAPPY NEW YEAR.

i have samsung SM-G906S. lately i have been facing the problems with auto rotation, proximity sensor and auto brightness adjustment. All these have stopped working. These problems are not with hardware because they vanish when i factory reset the phone of reinstall OS using samsung smart switch. but these problems occur again after some time (a month or two). seems like some problem with samsung firmware. too bad the official support from samsung has stopped for this phone.
Hello!
I have problem with moisture detected info since 2 months all the time, I tried to clean port, charge when phone is off, Restore factory settings, but nothing helps.
Change usb socket is almost impossible in home, so I'm looking for some rom/mod with software bypass for this issue. Maybe You know something about it Guys? I need Your help really cause wireless charging is tiring..
The only thing that maybe possible is NFC charging......

Try to use rubbing alcohol to clean the port. I got the same issue just by visiting a beach ⛱
I Tried clean port many times (everyday I'm trying) but nothing changed, so if it's impossible to disable this sh** by root/software so i need to reinstall usb port in service :/ Very disappointed by samsung..
Put the phone in a rice bucket for a day. It will dry out any moisture inside
