SIM card frequently disconnected - LG G5 Questions & Answers

Hi all,
I have the G5 since May and have the following issue.
Since about a month the phone doesn't "see" the SIM card from time to time and there's nothing I can do beside rebooting, which then recognizes the SIM again. Screenshot attached.
This has been getting worse, to the point where, today, the connection won't last longer than 5 minutes and then I have to reboot
I am unsure if it's more HW or SW, as the reboot normally fixes the issue. I have also tried to extract the sim tray, "clean" the card and re-insert it, which didn't seem to change a lot. Today I haven't tried that yet as I'm on WIFI and the phone is undergoing a system upgrade.
Has anyone had this issue??
Thanks..

Did you tried to contact lg?

I also have this issue, though mine seems to have degenerated at a much faster rate than yours. It started this morning when I think I got some water in it from the shower? Perhaps that is related?

That is definitely related. I hope you dried it out before continuing to use? I know where all guilty of this. But when you take it to bathroom for shower. Put a towel over phone. Away from shower so no moisture or splashed water gets to it.

Phone randomly restarting and not booting up

So i see there are a few other threads but none that i found were quite like this. My phone randomly restarts and goes to the white screen that says stick together and won't load back up, also when i reset or take the battery out unless i have held the phone infront of my AC in my car or put it in the fridge/freezer it will not boot back up, it has heat issues but it's not actually that hot, i used to play playstation games and it would get much hotter and not freeze like this, it randomly started happening a couple of months after I got it.
it will freeze often in any temperature that is not considered cold, even in room temperature it will do it, any time i try to load my playstation emulator or use the internet it has a very high chance or resetting and not booting,
if the phone gets warm at all though it's a garuntee that it is going to happen, it just depends on when, i could just be finishing a call, sending a text etc, it will happen, and the only cure is putting it in the fridge.
i'm going to guess I have a virus of some sort or something really messed up in the ROM, but i've switched ROM's and it still does it,
should i do the SD card hspl back to SPL and try to find a legit original rom copy or is there a better solution for this? i.e deleting all my addons and going with a different ROM?
my rom history is TOUCH XTREME, Miri and Dinik(this is where it started) and now Energy(it is still happening here)
might be a good idea to go back to stock, though you dont need to remove hspl at this stage, just flash your phones original rom over usb, and have a real close look at the battery pins, they can often get bent leading to all kinds of reboot issues.
If its still the same under stock rom, then maybe remove hspl (no need for sd card flashing, can remove it using hspl2/hspl3(for tmous))
one of my pins was actually bent a while back! i bent it back to the shape it's supposed to be and used a safety pin to widen it back up so it looks like the rest, do you think that caused permanent damage? and if so is there something i can do to the pins to make it work right again? and not reset so easily
Well, i reflashed the stock SPL and ROM and yeah it won't even turn back on, just stays on the white stick together screen. it's done, being replaced by tmobile next week.
hmm, could be, perhaps if the pin is cracked a little, affecting power flow. not sure what to suggest.
I got the exact same problem as lllpulselll. I have already done a lot of things but none of them worked for me.
I did an hard reset
Tryed a lot of different rom's
Used the telephone al while without SD-card but still the same problem.
But I read somewhere that ik could also been your Sim-card, is that logic or not?
And by me also one of the pins by the battery is not right so I will that try to.
(Sorry for that bad English)
looks similar to overheating, you could install BattClock (it can monitor batery temperature) to check whether the self-reset happens at the same conditions,
had the same issue, finished with new mainboard (replaced under warranty),
during worst moments before repair I had to put my Leo in the fridge for few minutes before it could restart

That's probably it then, probably bent the metal things connecting to the battery and messed up the flow causing the battery to overheat or think it's overheating somehow. sucks that that is all that's wrong with it and it has to be replaced, wish the prongs could be repaired.

not necesserilly so don't blame yourself - mine had faulty mainboard (not battery) probably from the very beginning, but as it was purchased in winter, the symptoms did not show up until late spring, when outside temps grew

Turning off

I just purchased my HTC Amaze five days ago and it is randomly turning off. It hasn't happened while using it, but it seems like every day now it has turned off while I haven't been using it. I push the lock button to unlock the phone and it is simply off. When I turn it back on everything is fine, but it is getting really old having to turn it back on so often. At first I thought maybe I was holding the lock button too long and accidentally turning it off, but that is not the case and the phone has been sitting on a table most times it has turned off without a case so the button isn't being pressed accidentally. The battery has more than half of the charge left so that shouldn't be the problem either. The phone just has the standard tmobile apps that came with it so that shouldn't be causing a problem.
Is this common? Is there a setting on the phone that turns it off automatically after awhile or at a certain time? If there isn't a setting is there a way for me to fix the phone or is it simply defective? I didn't buy the extra warranty, but I am within the 14 days to return the phone but it says on the box there is a 50 dollar restocking fee.
I bet there would be no function called automatic turn-off on this phone...and personally I have never faced this issue so far, during my half month period of daily use. Even there is a charge (which I never know), I would still suggest go for exchange. Random turn-off may relates to hardware defect, and is difficult to fix through software change. Try another one and hopefully that would take your headache away. Good luck.

Exactly what I think.
OP: If you are within the grace period, you can exchange the phone without restocking fee, especially if your device is defective.
Good luck!
Two other things I thought might be completely unrelated is that whenever I turn the phone on it says no sim card and then recognizes that there is a sim card and gets a signal and starts working immediately after that.
The other thing is that it says new voice mail whenever I turn the phone on, but when I check the voice mail there is none.
I took the sim card and battery out and put them back in. The no sim card message on start up is gone for now at least. The odd thing I noticed when I put the sim card in is it seems to slide in too easy. On my old phones I am used to a little bit of resistance when putting the sim in, but on this phone it goes in really easy, almost too easy. It seems like it could be easily jarred or even vibrated loose.
Is it supposed to be so easy to slide? Would the phone turn off if it stopped recognizing the sim card?
Thanks for the replies, I haven't ignored them, I am just trying to avoid having to go all the way back to the store, but I will if it shuts down again.

A loose sim card causing shutdowns? Hard to imagine how.
I just checked mine, and the metal restrainer is keeping my sim card pretty tight. It is not supposed to be moving around as you guessed.
My sim card sits pretty tight too. The "no sim card" message also pops up every time I turn on the phone. Guess the phone needs a short period to detect whether the sim card is there. For the voice mail I have no clue yet, check with your carrier maybe. Within the grace period I guess you could use this loose problem to support your demand and hopefully the store would not charge you any.
For the random reboot issue, try to do a master reset and that should help. I had that same problem the first few days i used it but after the reset it went away. It wouldnt hurt to try. Just remember all the free apps you downloaded because they will go away.

For the ghost v-mail...use a different phone or have someone call you and leave you a v-mail...as soon as you delete it the ghost voice mail will be gone too. I used to get these all the time on my HD2 and when I called T-Mobile that is what they told me to do...works everytime, until it pops up again. It was explained to me that it happens because you HAD a v-mail at one time and it got stuck in limbo when you deleted it, thus a ghost v-mail.
Thank you for all the help. The factory reset fixed the phone. It hasn't turned off once since I reset it several days ago and it was doing it every day before. Leaving a voicemail also fixed the voicemail that wouldn't go away.

wet s2

I recently got my galaxy s2 wet in the rain while running around in very stormy weather (people in Brisbane, Australia will know what I'm talking about). I dried my phone out quite well, with no problems but one. Sometimes when I call people, or they call me, the phone will completely turn off. This never happened before and is really quite annoying. The amount of time it takes for the phone to shut down varies, some times it takes 2 seconds and sometimes it takes 30 seconds.
What I want to know is if this problem will persist forever, or is there is anything that I can do. I'm leaving my phone overnight without the battery in in rice for the next few nights to see if anything will help.
If it helps - due to my idiocy - I left my phone on when it was wet and decided to also charge it (where moisture most likely got into the charging port). It had small problems before such as thinking it was still charging when the charger was not in, and that the voltage was too high when I was charging it, but all those problems have disappeared, and the only problem now is the infrequent and annoying phone shut downs when I'm in a call.

This just ensures the phones grave is big enough to be buried it.
Phone might have worked fine if you kept it in rice for few days immediately after it getting drenched. But now..oh well

Damn are you serious dude? The thing is though everything about my phone works perfectly now apart from the random shut downs when i"m in a call. I was thinking maybe it was a problem with my battery or sometihng being lose or the connections not being so great anymore. It charges perfectly now as well.
It's not in every call that the phone shut downs either, it's only in some calls. I've had phone calls where the phone will not shut down either.
Do you expect someone to wave a magic wand and your phone will be alright on every call.Your dealing with water and sensitive electronic equipment.A guy on here went swimming for 15 mins with his phone in his pocket,and he dried it out properly and reported no ill effects.
Other guys report slight moisture around usb port and phone acts worse than yours.
At the very least,you should be changing the battery and usb port.Any damage to the mb makes the phone a dead loss,and the phone wont have warranty as samsung checks for water damage.
If I was you I would sell it,but keep it if your not bothered about the calls problem and you cant afford about a £100 swaparound.

Only you know the extent of the damage, if you've wrecked your phone you've wrecked your phone, no point asking here.
However, the S II is pretty good when it comes to water if you take proper pre/postcautions. I've had some lonely nights with my S II where it got very wet and I can report it still works as good as the day I got it (I did have a lot of tissue paper on hand though).

First time I ever got my phone wet so everything slipped my mind. Will get a new battery and look into replacing the USB port. Just was wondering if there was anything I could do with my call problem, but I guess not anymore.
Any recommended batteries worth purchasing? I've heard that there are ones that are better than most out there but just not specifics.
Cheers for the input. I'm not too bothered with the calls problem as it works more often than not I've found.
Youll be hoping nothing else crops up or it fails if you need it in an emergency......thats how Id get rid of it.
You could maybe sell it to some unsuspecting mug.

[Q] ATT Mega overheating issues?

Hello, just wanted to post here and see if anyone else was having similar experiences with their phone.
So I have the ATT Mega, and it has been working fine for a little over a month now from when I first got it, love the phone. Last week or so, I noticed the battery would seem to drain much faster then usual and the back top part of the phone, where the camera lens is, would heat up very badly even when not using it.
I tried killing apps, restarting, nothing seemed to work. I checked the app manager and the battery stats, nothing out of the ordinary but the drain was there and the heat was so bad you really didnt want to hold it.
I contacted ATT and they sent me a replacement which I received last night. I turned it on and was trying it out and within minutes that phone started heating up in the same spot too.
They didnt send me a new battery because oddly enough the battery or that entire area in the back would not get hot at all, only the top half.
I contact them again today and they said they would send me a battery to try but I am scared it will not work again.
I also have a 64gb SD card that I use, but it is the same one I have used in my Note 2 and now this phone with no problem. I am currently using a Note 3 with the same SD and have no issues.
I would love to go back to my Mega though, I actually prefer it to my Note 3 but I am worried about this issue reoccuring or not getting fixed in the first place. Anyone else have anything similar to this with their Mega??
Mike
I have noticed it gets warm, but only when streaming videos. Just browsing the web or listening to music/iheartradio, nothing gets uncomfortable. I just notice the warmth after many minutes of streaming. Not uncomfortable either. Now I do have a case on it, so maybe that's why it doesn't seem as bad.
I have an i9205, but it's basically identical hardware. I've never had any overheating issues of any kind. Recently I've been running the "performance" CPU governor too, which locks the CPU at 1.7ghz constantly and yet I've never been able to make the phone throttle itself back.
Thanks for the responses! I am having ATT ship me a replacement battery to try that, hopefully it arrives today. I just dont understand why it would heat up so badly on both my original phone and their replacement one for me. I would think it has to be the battery or the SD card, but the card has no issues in my Note 3 and it didnt have problems in my original Mega for a month.
Crossing my fingers that it is just the battery so I can go back to using my Mega, I miss it -.-
I noticed my Mega getting warm in the same location last night, but didn't have battery drain. This is a replacement Mega since I bricked my pervious one, but never had that problem with that phone. Today, after being fully charged and not used while at work, I checked my phone and it was 15% and warm. So I turned off WiFi, GPS, and Bluetooth and plugged it in a 1 amp charger, 13% and still warm after a few minutes. Airplane mode, 12% and still warm after a few minutes. Turned the phone off and charging for an hour, phone is cool and 37% (makes since). Phone has been on, charging, and WiFi, GPS, and Bluetooth turned off for 43 minutes, phone is cool and 56%. Now I'm turning WiFi, GPS, and Bluetooth on individually to see if it repeats. I'll keep you posted on my results.
Thanks! I will wait to see your results!
Ive no issue with mine...
Well, sorry to say, it's been almost a month of me playing with this phone trying to duplicate my one time overheating with no luck. I've WiFi streamed for hours, transfered huge files over BT, viewed videos, and anything else I can think of with nothing. Maybe it was a fluke...who knows.

Zero issues here
Its been 2 weeks since I got mine and I noticed the phone getting hot around the camera but it suddenly started being normal with no heating. Will try for few more weeks to see what is the temperature level

My friend kind of had the similar situation... in his case he changed the phone
My Samsung Galaxy 6.3 is getting hot on the ear piece and the back of the phone where the camera lense is. What's the problem? I need to know if I need a new battery or if it's the Motherboard I need to replace and will the phone blow up in my face till I fix this problem?

HELP no sim or SD detected

I was on evox everything was fine and i thought id try the new Havok, i clean flashed as normal and (this happened before but only for alittle and format fixed it) now my SD or my SIM arent being recognized, not even in TWRP.
I tried reflashing vendor/firmware, format, wiped everything still SD wasnt being detected but it did show up on PC and i saved all my data. I then formated SD and still no detection.
I reflashed EVO and all worked except sim and SD, so i went and did a full miui flash with mi tool.
Im now at miui setup page and its asking me for sim when its in there, tested my sim in my friend iphone and it works.
Is my phone burned?
well in the end after a hard shake of my phone the sim and sd it started working again, for how long? who knows.
phone repair guy said it would cost probably 300-400-500shekelw to solder, the phone was bought for 1000 so fk it.
question if anyone knows this is the phone signal graph from gsam, it used to never go below 40,, does this mean im losing connection during the day?

Yes. If you travel with the phone, this may be normal. If the phone is in one place the whole time, then either you have an issue or your mobile tower/provider has.

I was completely static sitting at work when these readings were taken, thing is same type of graph happens at home also . Previously the graph would be always between 40 to 80 and no sharp ups or downs all just normal(fromnexactly same locations) and this erratic signal only started after i lost my sd and sim connection for like 12 hours (shaking the phone brought it back which leads me to think it hardware).
My gf once shoved in a pin to eject the sd and i think she did it too far or something and nicked some solder point since shortly after the sim and sd stopped working, but everything went back to normal after a while. This second time it happened again that i lost sim and sd and now i have this erratic graph where it says my signal is at 0 but i still got a call.
Jsut to try i switched from evox to crdroid and i observed the same type of signal graph so its not a rom thing.
these readings are from when i switched roms to test and its the same.

I had problems with download speeds, i was getting like half normal.
I FIXED it though with a bushfix, i put like 4 layers of cellophane tape on my sim card and now it seems it presses it in better, my stats are now steady between 40-80 depending if im indoors or out, no drop offs at all.
I hope this lasts! if not looking into mi 9 or K20 pro.

I'm having the same bs with mine (losing SIM and sd card access periodically). I have the added ballache of random shutdowns for hours at a time.
After noticing one side of the SIM tray was slightly worn down and wondering if it wasn't pressing the cards onto the terminals sufficiently firmly, I tried adding tape. One layer didn't do the trick and I was reluctant to use more and get it stuck inside the phone.
I've ordered a new SIM tray from Ali express - hope this will do the trick

Really grinds my gears having this stuff happen, at first i thought the connectors were broken, im not sure if its the tray though cuz i took my girls poco sim tray with her sd an last time it dint detect hers either.
Try what i did first to see if it helps, 3/4 layers of the clear tape, put it on the sd n cut to size.

Soo you are saying that sometimes your simcard would randomly die with no reason, and even after getting out and putting back didn't 100% fixed it?
Also that your phone suddenly died for like 2 hour and you couldn't start it no matter what?
Cuz i had these 2 problems.

Yup, that's what has been happening. Sometimes popping out the SIM and reinserting it helps, but often it doesn't. I've found it happens less when the SIM is in the SIM 1 slot rather than SIM 2, meaning I can't use an SD card. Makes me wonder though if it's mechanical, hence whether a new SIM tray might help
Random shutdowns are a PITA. They've lasted days before now
I returned it to Xiaomi for repair. They found it started up and returned it insisting it is fine. Despite videos showing the problem. Waste of time!
Did you manage to get yours over this or is it still happening?

It didn't happend after 3 shut downs. And neither the sim issues. Just to be sure i CLEAN FLASHED AND LOCKED BOOTLOADER than unlocked again and clean flashed latest xiaomi eu. Since then i didn't had any of those problems (but i got another one, maybe because of malakas kernel, rarely my screen would get stuck and only reboot could fix it(or touch sensor, not the OS)

I've done factory resets, without any improvement, but haven't relocked my bootloader
Might try that if I can summon the resolve
I've half convinced myself that it's a mechanical thing though with the positioning of the SIM card seeming to make a difference...

I had the same, couldn't fix it and i got mad and put it in slot 2,whitout sdcsrd, than it worked, i was afraid that i bricked sim 1 (its sim 0 in reality but doesn't matter), than i put it back and never had problems since than. I recommend you to:
Clean Flash back 9.6.27 beta with miflash (while relock bootloader)
Unlock bootloader, install twrp, CLEAN FLASH (well i didn't wiped system cuz some people said that on the forum, and tbh doesn't affected me) latest xiaomi eu (again, whitout wiping system but wiping all), install malakas kernel and latest magisk (13 or even 14) and if you want install FDE.Ai.
If you have problems even after all of this, than it's maybe damaged hardware, which is very unlikely.
my sim has been with stable signal strength since i put acouple layers of tape on the top.
flashing things ddidn't help me at all. I was considering mi9 to replace but developpement on K20pro looks like it will b way better.
so dar everything works so ill wait a couple months before buying a new phone.

Unlock bootloader, install twrp, CLEAN FLASH (well i didn't wiped system cuz some people said that on the forum, and tbh doesn't affected me) latest xiaomi eu (again, whitout wiping system but wiping all), install malakas kernel and latest magisk (13 or even 14) and if you want install FDE.Ai.
If you have problems even after all of this, than it's maybe damaged hardware, which is very unlikely.

I've just been on holiday for a week, during which time I had no shutdowns at all. Could be total coincidence, but a few days before I went I moved the SIM from slot 2 to slot 1. I've done this previously and still had random shutdowns, but strangely this time it seems to be behaving currently. Most odd

I never had problems agaon, BUT like 2 days my sdcard disconnected and could never put it back, even if it worked in another phone...
Solution?
Recap: since my F1 was about 3 months old I've been getting apparently random shutdowns lasting moments to months, also similarly sporadic signal loss and disconnection of the SD card. Have returned it to the manufacturer who took a bunch of cash from me, found it worked when they turned it on and returned it to me. A couple of days after receiving it back it shut down and continued to do so, exactly as before I sent it off. I started putting the SIM in the other slot and it worked reliably for about a month, then it all went to rat **** again.
About 2 weeks ago it shut down and wouldn't restart since. Pissed off with it and content that the warranty has no value, I took the back off last night and found that the antenna connection was loose. I pushed it in firmly (along with all the other connections to the motherboard - battery, screen etc) and fastened down the black motherboard bracket / plate / cover a bit more securely than previously, put it all back together and....
When I pressed the power button it sprang into life!
First time in 2 weeks and it's been steady as a rock since
I hope I'm not posting this prematurely - that the problem won't recur now I've tempted fate, but the initial signs seem promising
Kind of wish I'd got my screwdriver out 7 months ago and saved myself all the fannying about!
Btw, this teardown was helpful in case anyone wants to take the plunge https://youtu.be/LlubcWbsSQk
