Intermittent Internet Connection - CMF phone 1

RajeshSundararajan

Hi all! I recently purchased CMF phone 1. It has a strange connectivity issue. Data speed drops to 0 kbps randomly. This happens on WiFi as well as mobile networks. The network signals are strong, and the other devices connected to the same networks are working just fine. Any help would be highly appreciated. It’s quite annoying because everything else with the phone is good. I am not sure whether it is a one off issue with my device or other people are also facing the same. I did troubleshoot like turning the networks off & on, restarting the device, resetting network settings etc. Issue isn’t solved yet. Please help. Thank you in advance.

RajeshSundararajan Hello there , it’s not clear exactly the issue you’re describing, what are you doing on your device with the data speed drops to 0 kbps?

Can I assume you’re using the internet speed indicator in the status bar?

If you believe there is an issue with your device - I recommend getting in touch with the support team, they should be able to help further.

Hi even I wa

facing same problem found solution turn off smart 5g option your data speed will be normal

Hi @Rob ⚡️ Yes, I’m using the speed indicator in the status bar to check. I’ll tell you a scenario, maybe that would explain the issue better.

I’m using my mobile for streaming video, no buffering and it plays smoothly. The speed indicator shows a good 2 MBps speed. Suddenly, the buffering begins and the speed reads 0.25 to 3 kbps. I’ve to close the app, reopen it, and open a video (basically I’ve to re-trigger data usage 3 to 4 times) before the connection gains the necessary speed.

This is not an issue related to any specific app. Whatsapp texts sometimes don’t get sent for several seconds. Banking apps pause for seconds before becoming functional. Etc.

I’d tried contacting the support team through a call. They gave me troubleshooting tips which weren’t helpful. So, before visiting the service centre, I thought I’d talk here to you people.

RajeshSundararajan Thanks for sharing this and good that you already tried support, what troubleshooting did they suggest out of interest?

- Have you ever had a similar experience with another device in our area/with your ISP?
- Do you use a VPN?

I’ve not read about this from other users here on community so perhaps others can chime in 🙂

I do have the same issue, My WIFI internet become very slow and when i check the "Receive link Speed: is is only 1MBPS.. But when I check the Internet speed on my MAC, Other Samsung phone, iPhone SE all are working fine…

I have reset network, restarted , nothing changes.. plz advise.. Just bough this phone yesterday from flip cart,, and unable to use the phone due to this…

I agree with you

Sometimes it felt the same, sometimes even though wifi is connected it automatically switched to mobile data and then again quickly switched to wifi

It happens multiple times a day for me

I have been facing the same issue since i bought the phone. Its just been a couple of days and the issue persists from first day. I have tried network reset and other troubleshooting but it has not helped. May be a software update could fix this issue.

RajeshSundararajan

@AKSTYLES issue isn’t resolved yet. And I visited the service centre. To my horror, they did a factory reset without confirming with me. I told them that I had already tried resetting the phone. But still, it’s like they know only one solution for every problem “factory reset”. Anyways, the issue wasn’t solved. It still isn’t.

I was hopeful about the September security patch. That didn’t fix the issue as well. Nothing OS 3.0 is around the corner. But I’m not sure whether anyone has taken note of our problem. Still hopeful.

RajeshSundararajan I mailed them multiple times and they just tell me to go to nearby service centre or they will arrange a pickup, but the problem is I don’t have much time for it as i have to go abroad is few days , along with this issue i am facing a weird issue that when i remove my phone from my pocket , it’s touch sometimes doesn’t work properly with my right hand for few seconds to maybe a minute and with my left hand it works perfectly fine . Same happens with the fingerprint sensor it doesn’t register my right thumb and always show dirt detected , while with my left thumb it works normal . I don’t know is there a bug in the phone or problem in my right hand but it happens for few seconds some time. Do you have any idea .

RajeshSundararajan

AKSTYLES I’ve the right thumb-left thumb problem too. It’s funny coz it seems like the sensor is biased. But i believe the recent update has reduced the frequency of misreadings by the sensor (it could be my imagination). Only we 3 people are talking about the connectivity issue. Are we the chosen ones? I’m not sure. All i see is the hardware is very much capable of smooth operation, occasionally it shows how brilliant it can function. I wish the dev team take a note of your mail & this discussion and sort out the annoying things.. btw, i don’t face any issue with display responses when taking out of the pocket.

RajeshSundararajan the phone is a beast in this price segment, the hardware and especially the software are too good . Well the problem is in our luck that we are facing these issues , otherwise people are really impressed with the network nothing phones generally give . Talking about this sensor issue it work perfectly well with my left thumb but it works worse with my right thumb , like while setting my right thumb in the fingerprint it takes a lot of time and always shows dirt detected for no reason.

But i must say overall the phone is too good in this price segment, keeping our issues aside..

And one important thing when i put this phone alongside with different phones and tablet and do speedtest it always lags behind, while it works ok ok when i use it alone. When i did the side by side speedtest with my realme device, the speed realme attained was around 60 mbps and cmf was struggling to even reach 10 mbps , maybe it has compatibility issues with our wifi or something ( I’m guessing) .

RajeshSundararajan

AKSTYLES I’ve no probs with the internet speed (when it works well). If it doesn’t drop to 0 to 10 kbps occasionally, it runs reasonably fast.

All points agreed, this phone is one of a kind, the display, battery, OS & processor are all great. Like i said, the issues we face are annoyance. They’re not deal-breakers, but sure as h*ll annoying sometimes. Since only our devices seem to be affected, I’m gonna try claiming a replacement. I’d suggest you to check the same & see if it’s possible to get the replacement before you take off.

AKSTYLES

RajeshSundararajan yes i agree, think we should try .

RajeshSundararajan did the replacement work out for you

I bought this phone yesterday and I am struggling with wifi speed and connection issue

Adi123

I am facing the exact same issues mentioned by the other people
networking issues in general, and very easily reproducible issues with wifi hotspot
Just use it and your connection will be dropped (but only after your screen turns off)
I have turned off the sleep and auto hotspot turn off optimizations both and yet there is an issue
I think there is an issue with improperly applied optimizations, maybe they should disable all optimizations while using hotspot etc, give an option to turn it off ourselves
This seems like a issue with newer CMFs mostly?
seems like the hardware used might be different now
I just hope it can be fixed via software.

Yea even I feel drops randomly when using YouTube shorts,

It’s annoying sometimes 😕 sometimes reminds me to keep the phone away 😂 good in a way NGL hopefully this a software problem and not hardware cuz I just got this phone
