[Possible fix] OnePlus 7T & 7T Pro "Phone keeps stopping" issue after recent OxygenOS 10.3.6 update already being looked into

New updates are being added at the bottom of this story…….

Original story (published on November 05, 2020) follows:

OnePlus 7T and OnePlus 7T Pro users are reporting about an issue where the pre-installed Phone app keeps stopping following the recent OxygenOS 10.3.6 update.

Those who have been around the tech world long enough will know that it is not completely unusual for new software updates to tag along unwanted guests.

In fact, this is the very reason we keep track of various bugs and issues affecting not just OxygenOS 11, but also the likes of MIUI 12, Android 11 in general, and even some individual devices like OnePlus 8T and Poco F1.

OnePlus 8T is still new, but not perfect

That said, it was never going to be an easy sail for OnePlus 7T and 7T Pro owners. In addition to being subjected to long periods of waiting for OxygenOS 11 update, 7T series owners are now dealing with a broken Phone app.

I updated my OnePlus 7T to latest OTA last night and it probably messed Phone app. I cannot access dialer. Phone is now on 10.3.6.HD65AA. What to do? Cleared cache for app, already used “Wipe cache” from boot options

Phone app keeps getting closed, after the recent update OnePlus 7t. Tried to clear cache and storage without any luck. No voice apps installed as well.

Hiii since I updated the latest version my phone app is crashing and I am not able to call anyone through phone app, my OS update version is 10.3.6.HD65AA PLEASE need solution urgently thanks…

As you may already know, the primary function of any mobile phone is to communicate mainly through phone calls. But for some reason, the OnePlus 7T Phone app keeps stopping whenever it is launched.

Below is a screenshot of the error message the app returns after the recent update:


This hasn’t been the case for long, rather, affected users say the issue started showing up after the most recent OxygenOS 10.3.6 update that brought the October 2020 security patch.

It is unclear what exactly went wrong with the new software, but it is indeed clear that OxygenOS 10.3.6 update is the culprit. Granted, a newer update should address this issue.

Considering how important the Phone app is, we expect that OnePlus will be swift to address this matter, something a staff member does confirm, as seen below.

We would like to inform you that the issue is taken care by the developer and the issue will be fixed in the upcoming OTA updates.


While we would like to believe the next OTA update will resolve this issue, only OnePlus makes the decisions on this, so we have to wait and see what the immediate future holds for affected 7T and 7T Pro users.

You can also keep an eye on our OxygenOS 11 update tracker to know when your OnePlus device bags the update, both beta and stable versions.
