Question Z Fold 3 constantly reboots - Samsung Galaxy Z Fold3

Hello, guys
first sorry for my bad english
I will try to describe my problem
so my fold 3 keeps rebooting, but only when I'm not using it, only when it's locked and nothing is running in the background. So far, the only way it works is to turn on the app from the local radio and the volume to 0 ☺☺☺ so it has to work in the background and if I put it on pause it reboots... please help
I tried everything I found on the internet:
- put official android 13
- factory reset
- after factory reset, tried without installing new apps
- battery device care > auto reset OFF
- deleted wipe cache
- safe mode > reset anyway
- test using Samsung Members > everything ok
I have no more ideas

try these:
remove sim card and see if reboots
plug in charger and see if reboots
put in the fridge and see if reboots
let me know if it worked

So i put wife sim old sim butt same operater and it reboots after 3min
I will try sim with different operater

ok so i have news
i try with different sim new one from tcom and same problem. after 5min it reboot himself
i go to my operater for new sim same problem it restarts
then i got mad and do factory reset butt this time without logging on google account or Samsung acc
and now it past 2h and he didn't restart
please guys help !!!!! don't know what to do

So after that, restarts with only insert sim card to device even new one for me looking like unfortunetly hardware issue and need send to service.
Esim in my opinion didn't resolve problem or only in half because device will be full working especially with sim card which enables fundamental function of phone like connectivity.

1. Try changing radio.
2. Get a new phone. It seems to me that something broke in hardware.

[HELP] Sudden problem with both SIM Cards not being recognized on any ROM

Good day! I just want to ask if anyone has an idea of how to solve a weird and sudden problem that happened to my phone a few days ago.
I was running Cyanogenmod R16 with Xcelerate kernel.
I use two SIM cards on my phone, but I do not use the first slot all the time, so when I'm not using it, I regularly disable it through the SIM card settings, and enable it only when I need it.
What happened is, when I tried to enable it, suddenly both my SIM card slots could not be recognized (The SIM card settings could not be accessed; and error says: "SIM card info not available. Menu cannot be accessed"). In the lockscreen, it says: "INVALID CARD." for both SIMs.
I tried both restoring a backup and going back to stock MIUI, but still, the problem was there; none of the SIMs could be recognized (I tried using other SIM cards too.)
My IMEI's for both SIM slots are fine.
I've looked up on other forums, but I haven't found any others with a similar problem on the Redmi 1S.
If anyone knows what I need to do to fix this, I need your help. Thank you very much.
Have you tried both sim in other phone..?
If yes,and both working then should be problem with your imei!

Yes, I've tried both SIM's on another phone, and they work fine.
Since my phone still shows both IMEI's when I look for it, I assumed that there's no problem with them. What are possible problems that concern IMEI's? So that I can look up on general IMEI problems.
Thank you very much!
May be this can help friend

Thanks for the reference. Backed up my IMEI and Restored it right after, but still no change. Still, thanks!
EDIT: I've already tried two newly bought SIM cards, and the problem is still present.
Was this solved? Happening to me right now..
Happening to me too... Unsolved
For me just blowing in the sim slot & reboot fixed after few times..
if you have TWRP backup your modem & efs partition, just restore it via twrp. it worked for me
Hello,
I have a similar problem.
SIM2 is not recognized at all. I can use SIM1 only.
Tried to switch the SIM cards and still SIM2 is not recognized.
Both SIM cards are working great on other phones.
Is it OS related issue?
I've got same problem. Try to clean the sim metal contacts carefully and gently with an alcohol and qtip or tissue. It solved my problem.

Sim card(1) "Sim card not detected"

hi
I have a very annoying problem whit the sim slot 1 (i currently test the slot 2)
Very often, the phone tell me "Sim card not detected", and i have to open the phone, dismount the card and put in again.. until the next time.. like i said, it's occurs very often, 10-15 a day..
Even when the phone is on the table without touching it..
I have rooting it and thats it.. 2.19.40.22
I would like to know if someone have similar problems before i try to reflash whit older stock rom??!
It happened to me briefly- After flashing my first full back -up back to the fone --then i did a factory reset and this fixed the sim slot problem

Hi, I think i have the same problem after testing the Cyanogen build for ZE551ML. Have you did a factory reset from recovery (wipe data, cache and dalvik) or a full stock rom flash ?
Thanks
Above, I was referring to the full 5gb asus ROM back up I made immediately after unlocking bootloader installing twrp and rooting, I installed svn ROM and backed that up too..stripped svn ROM further..backed that up too. Then went about trying my Asus full original...sim 2 was only detected..so did a factory reset and sim came back.
To get sim recognised in CM,I had to wipe usual..install..set up...and factory reset it...hope that clears it up a bit lol

Oh,try a reboot after factory reset..I forgot to put in description above
Guys can you check your sim holder lock . I mean when you put the sim in holder check if it is properly fitted. Issue is some SIM cards are thinner than normal and sim holder unable to grip it. I faced same issue.
Also recommend using ASUS ZenUI app called ASUS Support. There are several helpful tips with basic troubleshooting techniques for your device including including SIM card troubleshooting. Please go to Apps/ASUS Support/Assistance/SIM Card/Sim card not detected

Sim Card not detected
Hey guys,
I am having a similar issue. I have 2 Sims, AT&T and GCI (local carrier). AT&T Sim works in both Slot 1 & 2, and GCI Sim works in slot 2 only. The AT&T sim is a standard MicroSim and the GCI sim is a Tri-Cut sim, so basically a NanoSim in a Micro Adapter.
Sometimes when the GCI Sim is in slot 1, it will recognize for a couple seconds then go gray..

Please if you have a fix let me know. reply here, or email me at bupbup777 at gmail.

I subscribe to the "theory" that some SIM cards are thinner than others and they drop out of slot 1.
In fact, I have 3 SIM cards and they range in thickness by around 0.5mm according to my cheap chinese mircometer. I don't believe that it is coincidence that the thinner ones lose SIM detection more than the thicker ones.
Also it is no coincidence that slot 2 doesn't lose detection becuase the SIMs don't slide upwards out of slot 2, but they do slide downwards out of slot 1.
Do this experiment: Put a SIM in each slot, now place a 3rd SIM in the space between the two. You will notice that it sits easily in the gap between the two installed SIMs with a bit of free play. Put the back cover back on and use the phone normally for a while (a day or two). Now take off the phone back and tip the phone over, does the "third" SIM fall on the floor, or has it been gripped by the SIM in slot 1 as it has gradually slid out of its slot?
Since I put one layer of sellotape on the back of all my SIMs, I have not had one single "SIM not installed" message. I used to get them all the time, especially with one of the thinner SIMs in slot 1 and above all when using the phone in the car (the fully vertical position and the vibrations seemed to have accelerated the SIM slipping out of its slot).
By the way, I never had the SIM slide completely out, but they certainly are not gripped sufficiently in place and slip enough to disconnect.
I had same "sim card 1 not detected" issue.
It worked back when i did soft reboot,.
And no more issue after factory reset
Re @ leftrand earlier on page 1.....
Sorry not been here in a while , but I think this was related to an earlier twrp we used , fixed with the later one I think. So it was a matter of restoring full original bk up,then factory reset then set up again and do another bk up. Keeping original bk up just in case . That was a while back now and should be fixed
facing same problem... only after updating ota. always.. sim 1 is not detected...

That no way to have a sim 1 working thru TWRP back up after flashing the CM13. What I did was doing a clean flash with SuperZen - 2.20.40.156 Full.
The problem was solve. then I flash back my back up TWRP. The phone now work like a charm.

I got it fixed bro! the phone does not like the Nano sim cards in the adapter. I happend to find an old GCI micro sim and had them activate it. works great now.
ok i found a solution. i read a earlier reply saying you cannot assess sim 1 whilst using a recovery back up flashed. i was currently using cm13 nightlys and this morning i flashed paranoid 5.1 or so.... i wanted to go back and compare the two but what i did was restore it from a backup.... so what you should do is when wanting to change roms, KEEP THE ZIP FILES THAT YOU USE TO FLASH THE ROMS WITH!!!!!!!!!!!! im still asking you to back up roms (preferably system before you flash) just so you dont hard brick it.
bottom line is back up rom, but keep zip files for when you want to change between roms. hope i can help
I have this problem, compounded by the fact that it seems all Android 6.0 (or possibly all CM based ROMs for the ZenFone?) have an issue where losing cell signal in a dead zone permanently breaks the radio until the device is rebooted. Even if the SIM is recognized, after going through a no signal area, the signal never gets acquired again and the SIM information lines remain blank or unknown. Trying to refresh the networks or providers list throws an error toast.

no sim error tmobile version ..

I have a Moto z2 TMobile version .. received it to try and fix it but it beyond my knowledge ... When u pull sim card it say no sim.when u reinsert it still says no sim card...
When u restart the phone it says nothing about missing sim or no sim at .. I have attached screen shots I have my imei and baseband not sure what else is missing that would work ...

Obviously, make sure you have a valid sim. You can try going to settings > Networks & Internet, click the 3dots in the right corner and reset your networks. In the same settings, you can go to Mobile network > access point names, hit the 3dot menu and reset to default. I'm not on stock, but I believe there is a setting in system settings to update carrier info, try that as well. If all else fails you might need to factory reset the phone. Have you tried another sim to see if you get any messages about sim? Again, these suggestions assume that the sim you have is good.
Happened to me on sprint moto z2 force. My fix? Extract the sim, put it again..

What did the tmo store say? If nothing is happening it seems like the slot itself has a problem. Can you see down in the slot? Is there anything jammed in there or anything messed up?

That's odd and it seems like a bad sim slot, defective hardware. The only other thing I can think of to try and it's a long shot is to DL the tmo app, sign in, and verify your sim number and imei on your account. I know it's active and working on the other phone, so maybe there's a glitch or discrepancy between the sim and your z2. You can dial *#06# to view your imei and the sim will have the numbers you need on the sim.

SIM card autodetect

Hi, I have installed Pie update on my Mi A2 Lite however due to amount of the bugs I got back to Oreo V9.6.10.0.ODLMIFF. Since that time my SIM cards got swapped - SIM tray 1 is visible in settings as SIM 2 and vice versa. What is more annoying whenever I insert new card while phone is on, it does not auto detect that SIM has been just inserted and need to reboot phone each time I replace SIM in order to get connected to network. Can anyone help me with fixing this so the SIM ordering is corrected in software and auto detection is back on? Already tried reflashing rom and getting back to Pie but no improvements.
