Phone reboots during calls

I have a similar,though not identical issue. Phone keeps rebooting,seemingly at random,every other day or so. During a call, listening to spotify,idle on the desk...i have an untampered with original Os on the phone.
Cheers,

Hi, I just registered to say I'm having the same problem. If you check the Amazon UK reviews too there are several people with this rebooting problem.

So far I have:

- uninstalled all additional apps I installed
- tried it with wifi and data off
- tried the other SIM slot
- done a factory reset

and it still reboots during calls. After the factory reset things appeared to work better in general (alarms now worked properly, and there were more options available, eg in the power button menu), but it rebooted 5 seconds into a phone call, which is a record. It's usually a few minutes into it.

The factory reset didn't actually delete my data (photos, files, etc), so I am going to do a reinstall via Fastboot now; firstly because I'll have to do that I guess if I want to send it back, and secondly to see if it finally fixes it.

I personally think the update process has screwed something up. It did an update as soon as it was powered on for the first time (it to 12.1), then a couple of weeks ago did another update to 12.1.1. It was rebooting before 12.1.1, so it is either 12.1 or earlier where the problem exists.

If it still reboots after a Fastboot reinstall then it's getting send back, and I probably won't ask for another. It's a nice phone, and a nice idea but I can't have a phone that reboots during >50% of calls. That's useless.

Pretty sure you can discount the update process too! I have also had this issue on cyanogenmod nightlies, I honestly thought I had inadvertently pushed the power button..but, NO

*edit* CM13 nightlies

That's strange as I have had no such problem with mine (bought in October) and mine is rooted with the unofficial builds of CM13... Maybe it is a manufacturing error and only on some devices...

Have you tried contacting Wileyfox?

I have not experienced this yet on the Swift when making or taking calls on it.

i'm on the latest cm13 nightly for crackling. each and every time the phone is called, whichever sim, the phone reboots. what a waste...

I have the same issue of spontaneous reboots, mostly during calls but also at other times. Spoke to Wileyfox who weren't very helpful. Has anyone found a solution for this?

Hi, I'm having the very same issue (appears a few are on other forums). Has anyone found a solution? I'm about to factory reset if it continues

Hi guys, so i returned my phone for repair, and they gave me a new phone. Must have been a hardware fault I assume

Hi thanks for the update, I've just factory reset, if problem persists I'll try to get a replacement too! Was it quite a quick replacement process?
