[Updated] OnePlus 6 users around the world reporting call drop issues

Update (June 09):

New update has arrived. Let us know in comments if it fixes the problem for you.

Original story:

Already off to a slightly shaky start, it appears the latest OnePlus flagship has another nasty surprise. The problem is a big one, as it inhibits the device’s basic calling functionality. Specifically, random call drops is the new headache for some OnePlus 6 users.

For over a week now, a significant number of OP6 early adopters have been chiming (1,2) about calls dropping after a few minutes of conversation, irrespective of their carriers. Reportedly, the problem occurs mostly for calls through the second SIM.

Call drop issues here too. Not when going to speakerphone mode, but just simply speaking on the phone. I can (mostly) hear the other side but they can’t hear me. Canceling the call then dialing again solves it. But only for some minutes then here we go again.

Couple of days now I have been getting call drops. when I am on the phone for say 10 mins the call can drop then I ring person back and can drop again after 5 mins.

No issues when you are using only one SIM. Call drops occur when you are using data on SIM 1 and calling through SIM 2.

Same here. Incoming calls inaudible from caller’s end. Call drops after 5-6 secs of being inaudible. Happens in 2nd SIM (Airtel). What’s wrong OnePlus ??

In addition to the help forums, some of the complainants even took to Twitter (1,2,3,4) to bring the matter to light.

The call drop matter, despite being reported by users around the world, hasn’t received any official acknowledgement from the company yet. FWIW, the company’s Twitter account is asking affected users to submit a bug report.

We hope OnePlus comes up with an official statement to address the issue.

Note: The call drop issue should not be confused with the already acknowledged ‘call sound disappearing in speaker mode‘ bug, as that is a separate problem.

Other call/network issues

It’s worth mentioning that users have also been complaining (1,2) about call/network issues in general. While not directly mentioning call drops, one of the complainants who managed to get a replacement unit over call quality issues said:

My replacement is arriving today. There technical team has visited me and den dey hv confirmed that the issue is with the device.

So looks like OnePlus is already aware of these call-related glitches. Anyway, coming back to the replaced unit, nothing changed.

I got my replacement device and same issue on this one too. I’m using Jio on sim 1 and Vodafone on sim 2. When connected to data on sim 1, network drops on sim 2, but you’ll get network on sim 2 when you are connected to WiFi. No trouble shooting works. Seriously hoping this is only a software issue.

Company confirms LTE/4G network bug

Remember the network connectivity glitch reported by European buyers of OP6, wherein the device fails to detect LTE/4G network for SIM in slot 1? OnePlus recently acknowledged the problem, with someone from their bug hunters team saying the upcoming update will fix what’s broken.

About this issue, it will be fixed in next update, please pay attention to it and verify it by that time.

Another potentially big issue

A serious call-related problem (currently being reported by a couple of OnePlus 6 users on XDA) has caught our sight. Users complain that despite hanging up/disconnecting the call, they continue to hear the other party. The only way to stop hearing the conversation going on at the other end of the call is to reboot the device.

Here’s how the complainant explained the glitch:

Yesterday I was on a call with a coworker and hung up… the problem it even though it said it hung up I could hear him and his wife talking for about 10 minutes (I was working on something with my hands and wasn’t at a stopping point yet). The only way I could break the connection was to reboot the phone… Clearly this can be horrible, people who I talked on the phone with may be able to hear me after I close the connection? Can get me in a lot of trouble.

We know that currently there is paucity of complaints regarding this problem. But in case reports pile up, this problem may attract a lot of bad press due to privacy concerns. We hope the company looks into the matter, and fixes up the vulnerability (if there is any).

Rest assured, we are keeping a tab on all the related developments and will update as and when anything newsworthy comes up.
