I have OnePlus One 64 GB Indian version. I'm on official CM12S, without Root.
Now my OPO working fine with the My Airtel SIM card till yesterday night, due to low charge my OPO is switched off and today's morning when started charging and switch on the OPO, my OPO face suddenly unstable SIM network. Get No Service and After 2minutes it Get Signal to Airtel. This loop continues till I put my OPO to 2G (Settings >> Mobile Network >> Preferred Network >> 3G to 2G - No Manual choice of network or LTE Network Selection helps both of them face same loop ).
I have self cut Airtel Micro SIM, Which working fine from Last 5 months on OPO from First Day.
1) What should I done to fix?
2) Is anyone face same problem?
3) Is any idea where the problem might be, In SIM card or OPO?
Hi,
I initially started with a OnePlus One and it came to a point where I would lose reception (Both data and mobile) maybe once an hour. The only fix was to restart the phone. I got fed up with it so I ended up getting a new phone, the Samsung Galaxy S7. It's been 3 days and I haven't found any problems, however, this morning I found my phone to have no reception. I restarted it and it started working again.
Could this be a SIM card problem? WiFi works fine.
Thanks
Not sure about the OPO but i had this happen to me where i lost reception for no more than 30s.
For you to restart the phone to get a reception is news to me and honestly have no idea.
I don't know how easy it is for you but with my operator it is very easy to just pick up a new sim card and ether have the shop to register the new card or do it by myself online. If the card is the same as the one you used with the OPO a new card would be the first thing to test. I have heard of lost reception problems were a sim card has been the culprit.

Is it the same SIM card from both phones?
Something has to be the same between them, either the SIM, or if it is a different SIM, then your location / surroundings / interference

Same SIM card. My location and surroundings don't affect when I lose reception. It just seems to be random. Both me and my girlfriend have the same carrier (Kodoo). I'd be sitting by my desk for a couple hours and have full bars and suddenly lose reception. Then restart my phone and I get reception back.

I'd request a SIM replacement, see if that fixes it, unlikely to be the phone if you have two with the same problem using the same SIM
Hi!
A few weeks ago i lost my signal on my Z5. I decided to order a new antenna and changed it and the antenna-cable. The signal came back for a short while, but disappeared a few hours later. So I tried to flash new rom since the phone is rooted. I have tried UK/DE/SE/Global, but none is working.
No signal, and the sim detection is very slow e.g it takes like 5 minutes after restart to detect sim card. Xperia-software from PC not working since bootloader is unlocked.
Can someone help me?
Best regards

Hallo all!
I recently bought for my wife poco X3 nfc and we have this issue. At random times although it shows it has signal it doesn't and she cannot make or receive calls. It needs to be restarted and then it's ok. The signal from our provider is fine when this happens because at the same time my signal is fine. I replaced the sim card with a new one but the issue still exists. Any thoughts on that please?

I think this is a problem when the phone is connected to the LTE network. Try to force your phone to use only a 3G network and see if the problem continues.
In the global Xiaomi forum there are many people complaining about problems related to the LTe connection
This phone looks like it has a lot of bugs
Well that is no solution but man that we force our phone on 3g..at the age of 4g and 5g phones..I had the same issue and only after restart yesterday did it get fine just hoping that it does not come back again
This problem happened on my phone right now. I realized that the cell phone has lost the SIM Card signal several times and now the cell phone has a Sim Card signal but does not make or receive a call. In addition to the problem of receiving and originating calls, it is also not connecting to the data network. I do not know what happened. This problem had never happened and even restarting the phone the problem was not solved.
Note: I'm inside my company's office. Other business friends use SIM cards from the same provider and are not experiencing this problem.
I don't know if it has something to do with the signal level of the provider.
Right now the phone is losing and recovering the SIM card signal for many times and is not connecting to the data network.
First of all thanks for the reply!
I will give it a try with your solution. Do you think it is a software or a hardware problem? I am asking this because if it is hardware, i cannot bare the fact of having a phone at 2021 with 3g as a solution and i will turn it back.

Man that sucks too I'll just try calling someone randomly to check if the bug is there or is not..further than that also the increased smoothness of the UI after restart vanishes after some days..why is that so..sd732g behaving like 660
Hi everyone! I have a problem with my Poco x3 Pro and I wanted to see if the same thing happened to someone, or ask for advice to find out where the problem comes from.
I bought a Poco x3 Pro 6 / 128gb 3 months ago, and last month, the wifi began to lose the internet signal since it is still connected to the wifi network but it is as if the signal was cut off, and it is enough to turn off and quickly turn the wifi back on on the phone to regain the signal.
It seems like something that can be quickly corrected, but when I'm playing online, it is quite annoying since suddenly without apparent cause, the Internet is cut off (with Wi-Fi and the network connected).
As additional data, it came with MIUI version 12.0.6 and although I updated to 12.5.2 (I also did a factory reset) the problem continued to occur.
Has anyone happened to you or advise me how can I find out the source of the problem? Since it could be my wifi (I really do not think so, I have a Redmi Note 9 Pro, Redmi Note 8 and Redmi Note 6 Pro and this does not happen, the signal is quite stable) or the same phone.
Thank you and sorry for my english haha
Firstly, 'forget' the WiFi connection on the phone and then turn off your router for a couple of minutes. Boot the router back up and once it's settled down re-connect your phone.
You don't say how often or quickly this occurs but if it does still happen then can you test elsewhere? Either a public WiFi connection or a friends or family members home maybe?
I get similar problem, usually after a night. Phone shows WiFi active, but no Internet connection and no ping to any local device. Other phones have no problems with the same WiFi network. It is enough to turn off WiFi on phone for a moment to get it working again.
My POCO is V12.5.1.0.RJUEUXM.
i have the same problem with my poco x3 pro 8/256, but only with wifi sign 5GHz, with 2G it working nomaly. i use Asus wireless Router RT-AX 55. i think it's isusse update new version, when i update 12.5.2 stable Offical
Since i inserted the SIM card, the problem seems to have stopped, but I don't see a direct relationship.. I will evaluate these weeks.
Maybe it switches to LTE? I have SIM inserted but disabled data and still notice problems.

Did these problems come to you from the beginning?
Yes for me. I didn't use this phone much, while waiting for bootloader unlock. It updated itself to MIUI V12.5.1.0.RJUEUXM at first boot and since then I observed WiFi loosing connection after nearly each night. But I noticed no breaks, while actively using the phone.

It is strange, in my case it will be necessary to test it with another WiFi..
PD: I update, it keeps happening to me, I will only use 4G to play games ..
I switched to ArrowOS and noticed one instance of WiFi failure. Then I disabled random MAC on phone and it seems to work OK now, but is to early to draw any conclusion. I don't remember if random MAC was active in MIUI.
While rare, problem still exist. Effect is that WiFi connection is broken an system cant find AP. But WiFiAnalyzer work OK and shows available AP. Turning WiFi off and on restores connection.
I have disabled protocol 802.11r on my network and for some days I have no more WiFi failures.

Okey bro, let me know if you have the problem again please, thanks.
I believe my problem is solved or rather circumvented and WiFi works OK. I'm using routers with openwrt. Maybe it doesn't cooperate well with Xiaomi.
Have the same problem, unmark "IPV6" and "QoS" in the router settings and problem solved.

Don't connect to 5G wifi on your router, , , Poco X3 pro 4G only that's why you disconnect.

5Ghz works perfectly for me. I presume you mean 2.4Ghz, not 4G?
Edit: or did I miss a 'joke'?

As described by Qualcomm's website the Snapdragon 860 supports 5G and WiFi 6 connections, but the Poco X3 Pro doesn't. Try to switch 2.4G

You've lost me, I connect via 5Ghz and don't have any issues, why would I drop to 2.4Ghz?

I think you are right, I separated the 2.4 and 5 GHz connections inside the router and I connect with the Poco x3 Pro only to the 2.4 and it has been perfect so far.
I will update the thread if there are problems.
Thx.
