Nokia 8 Randomly Restarts and Sound Problem

-automatic restart when battery percentage falls

- automatic restart if opening any or most camera apps

- sound from speaker is stuttering on full volume

- automatic restart if charger is removed

- auto restart if turning on wifi

- auto restart on doing full brightness

Even I'm facing the same issue with my nokia 8, it's on its own mood now

Same problem... But I used nokia 8 2years with no problem... I think sometimes hardware problem, because recently my phone dropped in my hand after that i noticed it

FYI: I had battery replacement on the last June at an authorized center. Now my phone is starting to show similar symptoms. So it's your choice of keep replacing battery or not.

If somebody did the replacement with 3rd-party batteries please inform me if your phone still facing the same problems? Just want to make sure this problem stems from battery or just defects from phone design.

To HMD Global, with regard to customer respects, you guys should disclose the root of problem, neither battery defects or poor circuits. So that the phone owners can choose whether or not to keep using phone.

The Chat Support said that it should be check and repaired by an authorized service center.

I do factory reset..... to and used new google account.

Nothing has changed.

I turned off Adaptive Battery in system settings. So far, no weird symptoms appear. You guys might give it a try to protect your phone, before things get worse.

Will give further updates.

Same here. My Nokia 8 suddenly restarts after I open the camera, some games like mobile legends, and some other time after I unlocked it thru fingerprint. Its warranty ended last January 2020. I observed too that, though the condition of the battery indicated in the setting is good, the charging stops even though there is a sign of charging shown in the upper right of the screen if I use while connected in the electrical outlet. Maybe it is the battery? Or anything else inside then component? Also the tab key does not light up.

Auto restart and unable to restore factory reset.

Try keeping power saving mode on. Works for me.

I had the same problem this is why I arrived to this site, did any one replaced the battery and did it solve that issues? It seem quite logical that this is the reason.

I been using my nokia 8 for nearly a year and one day i left my phone charging overnight i was a issue with my phone it doesn't say 100% charged it will keep on charging. Now my phone's charging is damaged i think so it takes too long to charge and it restarts randomly.I don't know whether its a battery issue or motherboard issue so if any of you guys knew about could you please help me out with this.

It's for very sure, this is not a hardware issue, if everyone facing it together at the same time. This looks like a business strategy to fool around people and get the hardware replaced. Why would everyone's Nokia 8 having same symptom and why would everyone's hardware fail at the same moment? Is this some kind of COVID-19 to Nokia 8, just kidding?

-automatic restart when battery percentage falls

- automatic restart if opening any or most camera apps

- sound from speaker is stuttering on full volume

- automatic restart if charger is removed

- auto restart if turning on wifi

- auto restart on doing full brightness

These above symptoms are common to all.

Nokia is doing this every now and then. Earlier they did similar things with Nokia 1020 where they failed to provide updates to the phone and stop supporting latest apps. Still we preferred Nokia phone but now this reboot issues. Its giving bad name to Nokia and they should do something.

I just tried that Hoàng, perhaps all my troubles will float off into space?

@martin.fd they just put a long comment of mine to "review" list. I am too lazy to retype all of it so just going to sum up in these lines:

- Battery is not a problem, the phone is. Because the OEM Scud Fujian also makes batteries for other phone vendors

- Most likely cause of premature battery death is heat. Shown in teardown video, this phone has a large heatpipe running from SoC directly to battery compartment. And stupid as it is, both battery and heatpipe lie on a single thin middle frame, therefore it could reach extreme temp quite easily. A hot battery cannot live long.

- So the solution is to try not using fast charger. At my place, the stock fast charger could heat the battery up to 42 centigrade. If you are able to open up your phone, wipe off all thermal paste (gum like pate) on the SoC to insulate it with mid frame. Together with avoiding deplete and full charge states as much as possible, solution by @Hugh Matthews. My proposed solution above, turn off adaptive battery could delay, but eventually the battery will die. I have done 2 battery replacements in the last 2 years.

- If those do not work. There is an ultimate solution: get rid of this phone, lol.

My mobile Nokia 8 not getting charge.

Decreaseing battery percentage randomly

Nokia care not receiving my phone

What is the reason?
