Pixel 4a No SIM card detected - Google Pixel 4a Questions & Answers

So, every since I have updated my pixel 4a to the August security patch, it starts giving me an issue with my SIM, it seems to not detect my SIM at random points of the day and I sometimes have to restart it multiple times to get it to detect again. After it gets detected, it will work fine for about 12 - 15 hours before the issue comes back again. When the issue occurs, my mobile network option in the settings will get greyed out. (see attachment below)
Went to my carrier and get a new SIM. Still, the issue persists. Even tried an E-SIM and it still doesn't work
I have contacted Google support and they told me to send my device down for repair and inspection however, even after repairing my device, the issue still persists. Factory reset does not fix it as well. Dig thru Reddit and Google forum as well, tons of others are facing the same exact issue after the August update leading me to deduce that this is not a hardware but a software issue with the update.
I saw that there was the September security update patch yesterday and I went to update it, however, the issue is still there
I then proceeded to contact Google support again and they kept telling me to send it for repair even though I already have?
Does anyone have a clue what to do?

If others are experiencing the same issue after the update, then that highly suggests the problem was caused by the update.
So, unfortunately, ONLY google can fix it with another patch and you will have to wait until google gets around to fixing it.

I have similar problem though I thought it's caused by android 12 beta so I outped out it and everything was fine for few days. I restated my phone after day or two and the problem of no serivce came back. This time even factory reset didn't help.
I can't manually change preffered network type to 2g/3g and everytime I try to make a phonecall it says i need to turn off aeroplane mode off.

Wow, unfortunate for sure. Isn't it possible to roll back to just before the update? Of course google makes the entire firmware available and I believe I've read if you remove the '-w' at the end of the script it doesn't wipe data?
At least if this was possible it would certainly indicate if it was the update or not?
cheers

So my Pixel 4a updated to the October Security Patch this night, and from there on it says "SIM not detected".
But when I go in settings it shows the network name.
I tried switching the SIMs with my Pixel 2 and everything works there, but any SIM I put in my 4a shows "SIM not detected" even though it can detect the network.
Which it probably wouldn't do if the SIM slot were defective, right?
And the timing with the update is too much of a coincidence...

I have similar issue - Pixel 3A, after update with November Security Patch, "No simcard" error appears with mandatory reboot. Tried with different SIM, there was prompt for PIN, verified and then it seems no access to simcard data. Even "emergency call" is no allowed from now. Looks like additional privilidges needed for access SIM card. No clue, how to proceed...

OTA update to Andriod 2.3.5 bug

Hi guys,
It seems that after receiving the new OTA update I ran into some issues.
My problem is that after installing the update my phone started to occasionally refuse to unlock the screen after pressing the power button.
If I connect the charger the screen unlocks but otherwise I have no option to unlock it.
I did a Factory restore (of course I lost every bit of apps I had installed - even tough I had the Backup settings activated-) and it seems that I'm seeing the same problem a few times a day.
Has anyone encountered this issue?
The phone is bought from Vodafone and original software installed.
Haven't rooted or S-off it.
Thanks
if ur phone is s-on and have same issue like s-off phones thats actually good news..seems that HTC messed up something...maybe is good advice for u to give phone to repair service if is s-on and see what thay can say about that.
I actually had that bug BEFORE the update, but not after. Instead of that, HTC Locations stopped working after the update and still is refusing to start even after factory resets and reinstall.
I have tried to contact HTC through their website to ask wheter something can be done about the issue, but the "Email Us" form doesn't seem to be sending anything after pressing submit and the "Chat with Us" form just shows blank white... I tried them on IE, FF and on my phone but they all show the same kind of behaviour.
It's really beginning to get irritating...
Clearly a software issue if it really happened after the OTA.
Wiping your Cache, Dalvik-cache partitions along with your Data (Factory Reset) should be able to refresh your phone as a "brand-new" one. That is if you can.
Stock recovery has an option to wipe Data and Cache.
If these still doesn't work, shove it to HTC's arses.,
Just kidding..
Send it for repair or maybe show it first to them.
some more bug.
-> live wallpaper sometime hang.
Starting yesterday I disabled the new feature "Trace keyboard" and since then the phone unlocked everytime.
Has anyone else kept this option activated and working ok?
2.3.5 OTA suxxxxs
Hi All,
I got OTA 2.3.5 Sense 3.0 on last Friday.
Since I have the screen problem = after a call sometimes I cannot unlock the screen with power button. If connect to the charger it's unlock and after the
power button works again. My phone is S-ON, fully original.
And I have 2 friends, they have Desire S and got this update too,
and after it the problem appear on their phones too.
So I think something wrong with new OTA update.
And I also notice the TTS Service, don't work too, it's always
halted.
(I made a factory reset and my friends too, but we have this problem too)
Any idea?
Everybody "got" this bug with OTA?
Bye,
Istvan from Hungary.
Wait for fix from HTC. They messed up something.
~Swaypovano sa Desire S BRE!~
I was finally able to get in touch with HTC regarding the Locations bug. The service agent said that he has never heard of such a problem before. His advice was that I should try the factory reset once more without the SIM card and without logging in to my Google account. I did that but the Locations still won't work. Only advice after this was to send my phone in for service... I'm really not happy with sending it in just to get an app (that was broken by their own update) to work again. I'm also pretty sure there was something wrong with the update to begin with considering all the new bugs being surfaced all the time.
This is really frustrating...
Would the people that have updated please tell wheter their Locations works perfectly? And if so, where are you from?

Try to disable the "Trace keyboard" feature. I did that and it seems that for the last ~18 hours I didn't encountered the unlock bug once.
Trace keyboard...
My "Trace keyboard" was off and the problem also present.
I tried to switch on, it hasn't any effect to the problem.
I hope the HTC will soon cede to this OTA full with bugs...
But as I known them, they not soo fast.....
Since the OTA update my Desire S crashes about once a day, and after it reboots it tells me it has recoverd from an error and asks me if i want to send the report to HTC. Seeing as how it reboots without any problems, and it works perfectly except the crash once a day, i suspect it has something to do with the flashing to 2.3.5.
Should i try a factory reset, or could there be another solution (seeing as how i really want to avoid a factory reset).
Oh and I have not rooted or S-OFF'ed my DS before the OTA update, so it's totally stock (as it has been since I got it)
I was able to fix the bug with Locations not starting up by changing my phone's language to English, then starting Locations, then changing the language back to Finnish again and voilá, it worked. One less problem for me.
I think that the Locations bug is limited to Nordic language versions (or even only to Finnish versions).
Hello
After update i have also the issue with the screen impossible to re-activate by power button after call is ended.
howto reproduce the issue: it happens only when screen is locked by security lock (PIN) and I receive a call. I pick up the call, screen is automatically turned off during call. After the call is finished, I'm unable to get the screen active again by pressing the power button!
Only working workaround is to attach phone to charger or connect to USB. Then the screen is activated and I can unlock it by PIN and working normally...
I need to have security lock enabled to be able to sync corporate email ( this is the security policy enforced by corporate Exchange server).

This new OTA update looks more like a beta testing for many users still haven't got it and those who got it are complaining about bugs.
Some are affected by power button bug and others experience difficulties unlocking their phones.
What makes the situation even more strange is HTC not announcing the update.

I'm sure you're right. HTC must have got a whole load of their people committed on new phones, others working on the recent security issues, so updates to our DS must be fairly low-priority. It smacks of the way that Microsoft beta-tested new OSes (perhaps still do) - Deploy many different public beta versions, don't bother actually reading the feedback but just simply measure how many complaints come in on each version. Finally, make official the version that got the fewest complaints.
I wouldn't be surprised if it goes quiet again for a week or so now.
The reply from HTC regarding the power bug:
Thank you very much for your cooperation and please be informed that we will get into this issue and we will try to determine what could cause these problems and what can be the solution. Please be patient with us because the investigation process itself it may take between 2 weeks and 4 weeks.
Have a nice day!
Disappointing
Hello,
After investigating further on my issue about "unable to resume screen by power button after call is finished" I described in my previous post I found it is most probably not related to OTA update but to HW problem...
I found my Proximity sensor is possibly dead. How the phone behaves (regarding screen on/off) during making or pick-up the phone is non standard. I also tried several android apps that are checking all sensors available on the phone and I see activity from all sensors except Proximity .
Talked also with HTC support... I'm going to sent my DS to HTC service center
Wish all getting the OTA update to enjoy it - I will certainly do so after I get my phone is repaired.
cheers
Ferro.
Pressing the power button during call or afterwards should light up the display.
At least that's what happened with the previous software version.
I'm still convinced HTC messed something in the update.
I have the exact same issue.
Has there been any work arounds how to fix this problem.
Mine's is on O2, never been rooted. Just stock.
If all fail looks like I will have to wipe phone and start again

*desperate* sudden Airplane Mode lock / zero radio

N5 purchased direct from Google in early spring, has been used as daily driver since then with little issue. In official hard silicon case since day 1.
stock 4.4.4, unlocked + root. Rather innocuous app list (TiBU, F-Droid / AdAway, etc)
Recently after a reset to attempt ridding of some minor issue (funky reception or something), upon finishing boot, phone didn't ask for SIM pin, as always prior.
Quickly revealed because phone does not even detect SIM. Different SIM from another carrier attempted. No difference. Original SIM also attempted in a different N5, still works. So problem appears to be with phone.
Nothing of note to precipitate this happening. Power menu shows Airplane mode is ON, but cannot be toggled. Quick Settings Airplane Mode can be toggled on and off and icon does change (so sometimes contrasting what power menu reports), but SIM never detected / activated / used, ZERO radio available. Attempts to make calls say "first disable Airplane mode". Many attempted combinations of SIM in / out, Airplane Mode in quicksettings toggled, resets, etc. No dice.
Everything else works with the phone, this came on suddenly.
Tried reflashing same radio. No dice. Tried flashing 4.4.3 radio. No dice. Tried factory reset and also re-flashing entire phone to 4.4.4. No dice.
After all that I am led to believe this must be a hardware issue, but I wanted to know if you guys had any suggestions before forced to send back in to Google.
Googling reveals some other instances of this happening to people, but no real solutions provided. Why would the hardware suddenly just die, and why would it present itself the way it does?
Side note, if it DOES go back to Google, does anyone know how to avoid getting refurb in return? That is all they are offering and will not budge. Yet less than a year ago I had to replace an N4, and received a new replacement, without even making a particular request for it.
Sounds like your radio hardware has gone bad you have done everything to troubleshoot software issues RMA it to google

[Q] No SIM card - Emergency calls only

Hi, everyone, sorry to bother you, but I'm in a bit of a pinch.
My unrooted stock Nexus 5 was running smoothly with then latest OTA update 5.0.1 until I got No SIM card error. I eliminated SIM card as problem source, removed SIM, discharged it completely and after few days turned it on and it was working. But problem returned soon and same method didn't show result. So things I already did:
- check my card in other phone: works
- check other cards in my phone: doesn't work either
- left it off without SIM for a few days
- erase cache
- upgrade to OTA 5.1.0
- factory reset
- unplug battery from motherboard for some time
- flash stock 4.4.4 from developers google com
- put some tape on card to make contact better
in this order. My next move would be to check if SIM card case pins are broken. Warranty expired month ago so there's that. Do you have any advice to give me? Is there any part of the phone that could've stayed not wiped during 4.4.4 stock flash and that's the reason problem remained?
You have a weather widget, clock, GPS location app that is causing the issue. Try uninstalling one at a time until you find the culprit. For me it was transparent weather clock widget that was causing this. Something about the way the app polls the GPS location causes problems.
I flashed stock 4.4.4 and only stock apps are present. I can either uninstall upgrades or root and delete gapps for good. What say you? I think phone somehow got "stupid" hard and I have to reset certain part that wasn't affected during flashing because it haven't once worked throughout process.
My nexus 5 is doing the exact same thing, exactly as you described, since the update. I'm losing my mind
Seeing as we both have the issue I don't think its a problem with your phone in specific. If anyone knows please help! I've tried uninstalling every app, going on safe mode, swapping sims etc

If it happened immediately or just after update try flashing stock KitKat.
Got the same trouble
The problems begun 1 week ago with interruptions with the radio, i have to restart the phone with Stockrom 5.1 self flashed and uber-kernel to get any connection. Switch the airplane mode often to get any radio signals. I ask my provider o2-germany for some trouble in their radio stations - and there was, just a few hours it worked. In a few days ago I traveled across germany, from the south to the north and back, got while traveling no good receptions, only gprs and edge. And now I switched from stock-rom 5.1 to OptiPop 5.1 the trouble begins with no-simcard ...
I will try xTraSmooth 5, when this ist not working i try an older image...
Edit:
OptiPop working now without flashing UBER Kernel. Now Issues so far!
Mine is absolutely stock on 5.1, not seen it once in 18 months and now it has done it twice in 12 hours.
I've always been completely stock and my phone started doing this every time I reboot it. Any more word on this? It also does seem my GPS looses lock on a lot too. This seems to have started since the last OTA update a few weeks back or so.
after i flash latest factory image mmb29v I got No SIM card error. There is an error in Safe Mode and SIM card not detected .pleas help me

Wifi / Bluetooth / Sim Card Issues Since Last Two OTA Updates

I received an OTA Update in early to mid May. I am now forgetting which version I received at that time. ( I forget as I have done so many downgrades/upgrades/factory resets in my troubleshooting the last month!) Up until these issues, I've never rooted or flashed a ROM, or unlocked boot loader or anything. My N5 had always been completely stock.
First Issue
It all started with just the sim card. I get "no sim card" message, even though it was in there. This was my original SIM card and I had never ejected it since I bought it new. I found I could turn it off, pop it out and back in, and boot it again. Sometimes it will see the sim card again. It may take 20 times, but finally work.
I naturally got a new sim card, as well as confirmed said sim cards worked in other phones. My wifi and bluetooth were working fine at first. Working with google support, they recommended a factory reset to fix the sim card issue. Immediately after the factory reset, my bluetooth would no longer turn on nor show a MAC address. At this point, my wifi was fine.
Second Issue
In addition to the sim card slot issue, now my Bluetooth no longer works! Around this time, I received another OTA update, this time it was 5.1.1 LMY48B. I had hoped it would fix the issues, but no dice! I start reading up on the XDA forums as I am determined to start rolling back to see if this will fix anything. I unlocked the boot loaded, rooted, etc following the threads on XDA
Third Issue
I do all sorts of flashing to hammerhead-krt16m_4.4 to hammerhead-ktu84p_4.4.4 to hammerhead-lrx21o_5.0 to hammerhead-lmy48b_5.1.1 . On the final flash back to 5.1.1 my wifi now no longer works!!!!!!!!!!! It is stuck at wifi turning on and no MAC address shows. It also seems my cell data is very very slow now!
After many calls to google, I think I finally succeeded in getting a “ticket routed up”. My phone is from the play store around 10/31/2013. They keep pushing I am out of warranty. I attempt to ask for a refurb N5 without luck so far. I am not very confident anything will come from google. This being my only handset now, it is just not an option to send this to LG. My current state is my voice/txt and cell data are working. Data seems a little slow but usable. Wifi and bluetooth won't turn on. I also still have the sim car slot issue upon rebooting. After a bunch of reboots it will eventually see sim card.
What else can I try? Is there a better way to attempt to repair/reload my radio drivers? Perhaps there is corruption of sorts? I have not tried a custom ROM or radio or kernel…… I did take to a local tech. They looked at everything literally under a microscope and did not see any issues that way. I am in the USA and have a lgd820. Although we are quick to assume a hardware issue, I am wondering if there is some sort of incompatibility with the first run of N5 and lollipop….. who knows!
I’ve read all sorts of threads on the internet. It seems I am not the only one. We are very quick to assume it must be a bad motherboard, it just seems too coincidental to me!

Hi,
This link was actually what i was going to suggest. It seems you've tried pretty much everything in the book except that.
I think its worth a try. Same as any other learning process, take your time and read the whole thing once or twice until you feel comfortable with the process. Then go for it.
Darn it, I should have downloaded those programs BEFORE rooting my phone again. Now I a struggloing to get my SIM card detected again to get data to DL them! whooops!
How would I go about attempting to read my files first to see if they are accessible and potentially write down my old MACs first?
EDIT: I found this but not sure how to get that working? I have Windows 7 and CMD prompt at this point. what program is that using?

OK, I went through those steps. everything appeared to go through correctly. Still no wifi nor bluetooth
EDIT: I rebooted a second time. WHen it first boot up, wifi was on and connected to my works AP. I quickly went in and snagged a screen shot of MAC address. Oddly enough, it did not match what I had input via hex editor. Within a few moments the wifi stopped working. It is back to the turning wifi on issue..... bluetooth still not working as well.
Very interesting.....
EDIT2: I get access denied when attempting to read either files within their corresponding folders under persist.
I was able to copy my stock files into my sdcard download folder and read them there without issue. Thus seeing my default addresses for both!
Perhaps it is normal, but I am never able to edit the old or new files under persist. I basically renamed original folders to bluetoothold and wifiold. I could delete them perhaps.
Note that I put my phone into airplane mode before doing anything noted in the steps.
Any other ideas? Given that it is showing my original MAC address the one time it worked, this makes me think that it is not reading the files .macaddr at all
I have the same problem. Funny thing is, the phone is just over 2 years old and the motherboard was replaced just 9 months ago (so, brand new one).
In my case, I received and Android update 2 days before I found the phone burning hot and restarting on it's own. Then the same chain of events you describe started to unleash. Now I can't be sure if this is software related, hardware related or both.
Can't seem to find a solution to the issue either.

I'm facing the same issues and I tried all the possible steps I could find on internet trying to repair the problem.
Actually, since the latest updates I was encountering some issues with the WiFi only: not turning on either off and not showing properly the MAC addres. So I decided to factory reset, even SDcard and since yesterday I have tried all the possibile guide I found to internet to fix the MAC address not showing and the WiFi not turning on/off but nothing worked. I tried even to flash again the old factory images, such as KitKat, Lollipop, etc., to lock the bootloader again and to dismantle the phone in order to clean the motherboard, but nothing worked. Phone still gives me MAC address 02:00:00:00:00:00 alternatively with the correct one, I can't figure out on what it depends because sometime it seems to work: it shows the correct MAC, it connects to wifi network; suddenly it doesn't!
I'm really going crazy to understand what's wrong.
You'll have to dig up my final posts on this , but in a nutshell, send into LG for repair, select cheapest option they offer. Receive mint phone. My cost was $45 and about one month... I picked up a cheap $20 phone to get me by.
In other news.... I now have a 6p!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Strange and significant reset and camera problems after latest update

I've got some very strange issues happening since the latest T-Mobile update to baseband G930TUVU2APC8.
The phone is a T-Mobile Galaxy S7 with a Sandisk 200GB micro SD card installed
Whenever I'm on a phone call through a my Jawbone Era (and charging; I haven't tried it unplugged) the phone will behave as if it did a reboot, without actually rebooting, every few minutes. The phone will stop responding for about 20 seconds, then show just the wallpaper for about 5 seconds, then go back to the lock screen. At this lock screen it requires me to enter my password instead of using fingerprint as if it had just powered up. The phone call does not drop through all of this.
The next issue is that some pictures taken from the quick launch are sometimes not saved. I'm not 100% sure that this only happens after the reboot issue above, but I think it does. I have secure startup disabled .
I tried a factory reset which did not fix the issue, contacted t-mobile and was sent a replacement device that still has the problem. None of this was happening prior to the latest update.
Has anyone else experienced these issues? Also, is it possible to downgrade the firmware version?
Thank you,
Matthew

The problem started in PB8 firmware, PC8 firmware has constant wifi dropout issues, you might find even that at 3G connection performing better than fiber optic wifi internet.
Easiest is to update facebook to latest version and see how many "can not connect right now" errors.
Random reboots is normal never mind how many times your factory reset or do a full firmware PB8 flash.
T Mo is not the brightest tools in the shed, it takes 5 visits to their T Mo offices to get the accounts and products purchased + refunds for items payed in cash or freebies refunded etc etc etc.....
