Nothing Phone (3a) Series - Connectivity & Network Issues

RayyanAzeem · 2025-03-26T09:45:11+00:00

Dear Nothing Phone Support Team, I hope this message finds you well. I am writing to report a persistent connectivity issue I’ve been facing with my Nothing Phone 3A, which I purchased two weeks ago. Despite having excellent 5G coverage in my area, I am experiencing significant issues with my internet connection on this device. To provide more details: Device and SIM Information: I am using an Airtel 5G SIM card in Slot 1. Games and Applications: I have installed BGMI, Call of Duty, and a few other games. The issue persists while gaming, as well as during general internet usage like browsing or watching YouTube. Symptoms: 1\. The internet signal randomly drops and after 15-20 seconds, it returns to normal. 2\. While gaming, my ping fluctuates significantly, even though I have fast 5G data with unlimited usage. 3\. While watching YouTube or browsing, videos start buffering or loading intermittently. 4\. I frequently see a "!" symbol next to the signal bar, indicating connectivity issues, which was not present on my previous device (Realme GT) where I had no such problems. Troubleshooting Steps Taken: 1\. I have tried removing and reinserting the Airtel SIM card multiple times. 2\. I have reset the access point settings. 3\. I tested the phone with a BSNL SIM card, but the same issue occurred. 4\. I have ensured that the phone is updated to the latest software version. Despite these attempts, the problem remains unresolved, and the connectivity issues are ongoing. This situation is particularly frustrating given that I have access to strong 5G coverage in my area and had no such issues with my previous phone. I would greatly appreciate any guidance or solutions you can provide to help resolve this issue. Additionally, if this is a known problem, I kindly request that you assist me in reaching out to the Nothing support team for further investigation or a software update that may address this connectivity issue. Thank you in advance for your attention to this matter. I look forward to your prompt response and assistance in resolving this issue. Best regards, Rayyan I am from india

Anonymous978 The Nothing team seems to have reduced the network performance after the Nothing OS 3.1 update. Since then, the internet speed and connectivity have become unstable — it often pauses for a few seconds randomly. This issue can only be fixed through a future software update from Nothing.

anjanyadavby I don't think it's an issue with the phone software as my 3a bought in August with NOS 3.2 has never given me data issues. Very rarely I get drops in Wi-Fi

Hi Nothing Support Team,

I am facing multiple issues with my Nothing Phone (3a Pro). After disconnecting a call, when I try to call again, the call does not get connected. I have checked with my service provider, and they confirmed that the issue is not from their side but from the phone itself.

Additionally, I am experiencing performance problems — the phone frequently gets stuck or lags, especially while using the camera or taking photos. This affects the overall user experience.

As Nothing is known for addressing customer concerns and providing quality updates, I request you to kindly look into these issues and provide a software update or solution to fix them at the earliest.

Thank you for your support and understanding.

I have just bought my NOTHING PHONE 3A in june, Bought a 5g sim, activated all settings, but 5g never connected (I'm using VI and when I put my VI 5g sim in a realme phone it started working correctly).

I have nothing OS 3.2 on my Nothing Phone 3a and in the last few days I haven't been able to use my device hotspot. Whenever I try to activate it in the settings after 2 sec it automatically turns off. Has anybody encountered the same issues? Any ideas for a possibile solution?

Hi Nothing Community,

I would like to share a serious network issue I am facing with my Nothing Phone (3a), mainly to check if other users are experiencing the same problem and to create visibility for the engineering team.

📱 Device & Network Details

Device: Nothing Phone (3a)
Country: Bangladesh
Carrier: Grameenphone (GP)
SIM: Single SIM
Nothing OS: Latest available update

❗ Issue Description

4G/LTE data works perfectly
But calls fail completely
When the phone tries to:
- fallback from 4G to 2G/3G (GSM/WCDMA) for calls, it fails
Incoming and outgoing calls do not work

The same SIM works perfectly on other phones, so this is not a SIM or carrier-side issue.

—

🔍 Technical Findings (Important)

From diagnostics and logs:

IMS status:
- IMS registered: ❌ Not registered
- VoLTE: ❌ Unavailable
- VoWiFi: ❌ Unavailable
- UT interface: ✅ Available

This means:

IMS registration is failing
VoLTE is not working
Phone tries CS fallback to 2G/3G for calls
But 2G/3G attach fails

👉 This strongly points to a modem / radio (baseband) firmware issue, likely:

Regional band mismatch for legacy networks, or
Incomplete carrier profile for Grameenphone Bangladesh

—

🛠️ Troubleshooting Already Done

Network reset
SIM slot change
Manual network selection
VoLTE ON/OFF testing
##4636## radio tests
Full modem & network logs captured and shared with Nothing Support

Nothing Support has confirmed they are investigating this with the relevant team.

❓ Purpose of This Post

I’m posting to:

Check if other Nothing Phone (3a) users (especially in Bangladesh or similar regions) are facing:
- 2G/3G fallback failure
- VoLTE / IMS not registered issue
Increase visibility so this can be addressed via:
- OTA modem / carrier profile update, or
- Official resolution guidance

—

📝 Summary (One Line)

LTE works, but calls fail because VoLTE is unavailable and 2G/3G fallback does not attach — indicating a modem firmware / carrier profile issue.

If any other users are facing similar issues, please comment and share your experience.

Thanks 🙏

RayyanAzeem The only thing that worked was factory resetting the phone.

After updation of nothing os 4.0 I face wifi connectivity issue. Some time wifi disconnects randomly.

It took 20-40 seconds to reconnect the network and this issue can be solved by an updation

This is my first nothing device and I am really tired of it.Do something immediately!!!!!
