K8 Note repeated sudden switch off. - Lenovo K8 Note Questions & Answers

I have the K8 Note phone with Android 8 and security path level : 5 March 2019
My phone is switching off unexpectedly and when I switch it on, it boots up to the lock screen and then switch off immediately. This is repeating at different times for different actions and I cant identify a pattern to replicate it. If I keep the phone connected to the charger then this issue doesn't happen. When I remove it from the charger it will switch off when I try to open some app or sometimes when receiving calls or making calls. It also happens when I open the app drawer. I have done a factory reset and also booted to safe mode,but still the issue is there. All these switch offs happened when the phone was not connected to the charger and the battery charge is more the 50%. I am not sure if the phone is showing the correct battery levels. Also I am not sure if any of the google apps is causing this issue. Can someone help me solve this issue?

So nobody has this problem ? or no one wants to reply?

i also have this problem & many users too after the last oreo update
i try every thing to solve it hard rest , downgrade & custom roms and every thing but does not work !

I didnt try any custom rom. I cannot find any official response from Lenovo about this issue. I will never buy Lenovo products again, and actively discourage people from buying.

I had exact same issue. Replacing the battery solved the issue. If you go to Lenovo Service Center, they will tell you that, it is a motherboard issue. But in reality it is a battery issue.

Yes, if your phone doesn't switch off when connected to charger and switches off suddenly as soon as you unplug or after a few minutes. Then probably the battery is at fault and needs to be replaced.

p5200 Random shutdowns

Hi all,
I own the p5200 (Tab3 10.1) for a few weeks.
Recently I noticed that the device sometimes randomly shuts down by itself, and I have to power it on again by myself.
It mostly happens when I don't use it (and than come back to use it and it's dead) - but it also happened once when I used it.
Did any of you guys experience that weird behavior ?
I don't believe it is a hardware defect, rather then a software/kernel issue (maybe even the previous generation's SOD problem?)
Appreciate any help!

The problem seems to be getting worse, now it happens a few times a day,
I read some and thought it may have to do with the Sleep of Death.
If anyone knows anything about it I would be more than happy to know,
Thanks,

Thanks for the reply,
I'm running stock unrooted/modified XXUBMI5 firmware.
Hi,
same/similar problem on my P5200/10", stock not rooted firmware 4.2.2 - after cca a month of using random switch-off started, after another few weeks it was more and more frequent and the tab was usable only very hardly. my quess was some HW error like bad battery concact, as it happened mostly during tab movement/shaking/turn arounds etc.
Sent back to vendor to reclaim, back after a month with factory reset and message "problem not reproducible". and really, it was not happening(!)
Another week or two has passed since then - and random switch offs are again back, now also when there is no movement (i.e. overnigth). I am planning to try to save some logs to find why it happens (some bad application?) or at least to prove to vendor it really happens. then I will try also another factory reset (however, I do not like to setup it again and again and backup/restore might not work, if it is caused by some app ).
When this happened to me on a previous device, it turned out to be SD card related. The SD card would unmount and that would apparently freeze my tab, usually shutting it down. Then again I was using a swapfile and had most of my apps installed to the SD card. But I figured I'd mention.

thanks, but I have no external SD card inside, there is just the internal one, which is not removable.

Hi,
Same here - no SD card involved.
I can update that "somehow" those random shutdowns did not occur in the past few days (where before it happened a few good times a day)
I can also say that when the device is connected to a charger no shutdowns whatsoever.
Also, in the past few days battery is draining much faster than before.
Personally I think it is the battery, October's bad battery batch of the S4/S3 reminded me that this could be the issue here as well.
Tried to look online for a battery replacement to buy, but without any luck so far.
alfi_ , if you have any new info I would very much like to know

Hi,
so far nothing special - as it does not happen while on charger, also log via USB is useless. and the log via TCP is empty.
what I have seen in discussions / heard from more experienced people, incl. the branded service partner, it can be often caused by some additional application (for me its hard to believe. and if the same happens to PC computer, it will definitely be a reason to return the device). but anyway I would suggest you to make a backup and try the factory reset too. then test it for some time without any new installed application.
for my one it looks little better after reset (weird behaviour), but it still randomly shuts down. then I am going to visit a service center personally to present there the behaviour, but it may take some time..
Hi,
the problem was reproducible also in the service center with factory setting without any other application installed, so after a month the tab is back with replaced mainboard (part gh82-07643a) - and so far no problem. hopefully it will not repeat anymore
I've been experimenting the same issue. Sm t311, stock unrooted rom.
It happens when the device is sleeping, it just fails to come back.
I've seen it happen with and without sd card, with and without power cord attached. It doesn't seem to be related with the sleeping timespan either.
Enviado desde mi SM-T311 mediante Tapatalk
one, maybe useful info when this happens, which I was not aware of - androids v4.1 and newer have the possibility to boot into "safe mode", where all additional installed applications are disabled. so before you try factory reset and reinstall/reconfigure all applications, you can try also this. (I am wondering this option was not told me by the service). on tab 3 10" you can reach it while booting and the logo is shown, press and hold both volume keys.
battery terminal
I seen a post somewhere that samsung forgot to secure the battery terminal, on some tabs. I have the pics of the teardown, in case I ever needed them. I'll post a link. https://www.dropbox.com/sh/rg53ls0004rgdjr/ARJ-ecv2NA/teardown (1)

After troubleshooting this issue and discarding possible causes such as charching problem, smart cover side effect, defective sd, etc etc, I had given up on my T311 and decided to start experimenting with some custom roms (after all, it's painless to brick a defective tablet). Somehow, after flashing FastDream the issue disappeared.
It has run for 27 hrs straight without turning itself off.

Hi, I have problem with my Galaxy Tab 3 10.1 gt p 5200.
Tablet without noticeable reason began randomly shut down by itself.
Sometimes in an hour goes off 5-6 times, and sometimes working 5-6 hours without turning off.
Tablet can not be sent to the service because it was purchased abroad.
On it is the original untouched Android 4.2.2.
I tried a factory reset and re-flash with the latest android from sammobile.com , but it didn't help.
Does anyone has a similar problem or solution.
Thanks in advance

Lg g3 endless bootloop with new battery

Hi, my phone suffered from bootloop and according to the tremendous posts about this problem the answer was always laying in buying a new original battery, which i did but still the bootloop continues, may open for a few hours then bootlop again,
if anyone could help that would be appreciated because i'm giving on the phone now
mines doing the same thing with the original battery..
interested in the answer before i outlay for a v20.
---------- Post added at 11:24 PM ---------- Previous post was at 10:33 PM ----------
I had a bit of a hunt around and i noted that the phone has an issue with the WiFi.. so i disabled the WiFi and Bluetooth in the settings
as a precaution i ran some tape over the NFC and Qi battery charging connectors, blocking these connections.
if this solves the problems.. ill be outlaying for a new phone soon.. ill wait for the G6 to come out before considering the v20
ill post back in a week if i experience the same issues.
looks like this did not fix the issue.. i will try a custom ROM tonight to see if it fixes the issue..
i am wondering if the battery is the key here, it is possible that the software is seeing the battery voltage and when it drops below a certain volt the OS automatically shuts down the phone to protect itself..
as i only see the boot loop when i am launching particular heavy load apps. and i don't see this happening when the battery is at 100%

some interesting points here.
Do you have a reboot (phone restart) or a bootloop (phone try to restart but it never pass the boot screen)?
Have you noticed temperature issues?
If you have already tried return to stock and the problem continue it probably is a hardware failure.

before with the old battery it started to freeze and restart then it got worse, it closes and bunch of bootloops then open then 2 minutes and bootloop again, until it permanently bootlooped ,so i bought new original battery from lg store and the phone opened first time then 5 mins later it restarted then bootlooped once again, thing is, by the new battery it opens sits for an half an hour or less then bootloop, with the old battery it never passes the lg logo.

Hi , I have the exact same problem and i thought changing battery is the solution but i got my new battery today and everything was fine at the begining but later when the phone tried to update some apps again it turned off .
I had this issue suddenly few days ago after install some apps or some updates .. I am hoping it is because of software issues and can be fixed after factory reset.
(phone able to start when it is colder , so i tried to put it 2 min in freezer and it started but just tried one time , i dont know just coincidence )
I tried to update my firmware to 6.0 MM , so nothing change.
Looks like nobody able to solve this problem. Now my phone is just garbage

I noticed the same thing, it works fine when it's cold or normal then lag and restart when it's hot (38C+), today i tried to disable heating lag and the thermal mitigation thing but still doing the same..

It is even better now because I opened up my phone and heatsinked the cpu .. I am still using lower cpu freq but even works without cpu adjustment after heat sink .. Now using 1.5 ghz just for incase.
(Still sometimes turning off itself when charging) Would be even better with heat sink pad i guess
I had heard that adding a 0.5mm thermal pad to the SOC makes its run a little cooler, but i do seem to think the battery is the main culprit, the main problem with getting a replacement battery which operates within the same tolerances.
downclocking the cpu to 2.0-2.2ghz with a fresh battery and adding a thermal pad on the SOC seems like the best solution..
I have since upgraded to a v20.. so hopefully it doesn't happen with that phone..
Some old original baterries have an issue that swollen a bit and the phone starts rebooting itself. But I don't remember from which year the good ones are manufactured.
Try testing with a generic battery (as I do) to see if that's the issue.
If you still have the battery's warranty, claim it.
I got a new battery, then charged it fully, then added an empty SD card to back up the data. Connected to a fast charger., otherwise it is not enough power to keep it on, causing a bootloop. The phone must be cool, not powered on for some time (overnight, in my situation).
I was able to back up the data., my main goal. I have heard others being able to fix it, and it works for some time, but soon enough this trick no longer works.

Device stuck in loop.. "Mi Logo" then battery icon.. this keeps repeating.

Friends,
My redmi note 5 pro was 50% battery and it suddenly turned off. After that when power connected no response. Connect via USB and Mi Logo appears first, then the battery icon with a flash symbol in middle. This repeats continuously. Some help, please ?
The phone is not rooted. Still in warranty period. No recent update. The last update was 1 month ago. No glitches after that.

Woh.. its been a long time, though I am still using the same phone. ?
Try a hard reset first, if it doesn't help run to the service center. Don't worry about your data, service technician can easily recover it.
Back then My phone came into contact with sweat moisture and it fried few chips on the mother board.
Fluid damage is not covered under warranty, yet they gave me 50% discount. ?
All the data was restored afterwards and the phone still working fine.?
Hope you will find a solution soon. ?
Hey, it might be a bit late but i found a solution: i charged my phone for a few hours in fastboot mode (volume down + power button). Then turn it off and on again.

I was also facing the similar issue yesterday.

Phone keeps rebooting randomly without power connection

I'm sorry if this has been asked before, but I couldn't find a definite answer anywhere. So my Lenovo Z2 plus which is rooted and was flashed with Flyme OS. I was playing pubg and halfway through the game, my phone rebooted. I thought maybe my battery drained but I tried to reboot anyway thinking that atleast it will boot up to show 0% battery, but it didn't. After plugging it in, it would work again for sometime then randomly reboot. And when I would reboot it myself, it stops right after the logo.it only moves further if I plug in the charger. So if it's a battery problem, why does it always reboot at that precise moment. And when it reboots randomly, it's not even hot - the screen, the back, anything. Sometimes it works for hours and would suddenly stop, sometimes it works only for a few minute after unplugging. There's no specific app that triggers this. I even changed the ROM to AEX 5.8, and the problem persists. Is it genuinely a battery problem or is it related to bootloader or anything. Because it does not reboot while in twrp. Any help would be appreciated

Now if I use my camera also I can't click a single picture, it just starts rebooting again and again.

Okay, so guys - I am using POCO F1, Started having this same issue yesterday, on the internet, I found - this is a hardware issue, and the solution is to get a new battery,
So I went to the Xiaomi Service center, Their engineer said the same, this is a dead battery issue. So I bought a new battery - and the phone is working fine.
so Final Solution = Get New Battery

A505FDDU2ASJ2 completely messed up anything USB / Charging-related

Hi guys! I'm posting here because I'm a little bit lost. I got a new software update today on my A505F (A505FDDU2ASJ2 - it's the 2nd update for October, the phone was already on Oct. 1st security level before this update) and I installed it right away.
Now the problem is albeit the phone does feel significantly smoother after this update, the charging algorithm is a complete mess (it was already buggy enough after the August update, which claimed it "improved the charging algorithm") and it's even worse after this update, it's now causing weird issues:
- The flashlight doesn't work anymore unless the phone is plugged and charging, what a weird bug!. If I try to turn on the flashlight without the charger plugged in, it simply doesn't turn on (Google Assistant can't turn it on either). The camera seems to be able to turn on the LED flash but it's completely bugged out, the flash keeps turning on and off and sometimes even stays on after leaving the camera (phone unplugged from the charger).
- The phone keeps throwing error messages telling me to "check the cable connection" when it's plugged in.
- The phone also takes more than 10 seconds to detect the charger (and keeps saying it's charging more than 15 seconds after unplugging the charger).
- The fast charging toggle on the Device Care\Battery Settings simply does not work, the phone will keep using fast charging even if the toggle is set to disable.
- If I turn off the phone, it keeps showing a battery with an exclamation mark and It's hard to get it to turn on, I have to find the right timing after the battery icon disappears to turn it on.
- My PC does not detect the phone anymore (it still charges it, though).
As you can see, there's something really wrong with that charging algorithm or whatever piece of software is in charge of the charging.
-PS: It's the 128 GB storage / 6 GB RAM version of the A505F.
-PS2: My friend's A50 exhibits the same behavior after the update while my brother's doesn't, any idea?
-PS3: I can't afford to soft-reset the phone right now, I really can't!
Thank you for reading, some feedback would be really appreciated if you do install this update.
EDIT: A soft reset didn't fix the issue. Bummers -_-
I have same version of phone as you and all problems after last update. Is there any official Samsung forum so we can report these bugs?
same as my mother's galaxy a50 after 2 updates(the first one is 400mb and the second is 200mb) when we connect the charge it doesn't charge. The error prompt is "connect charger" even it is connected.
We try to charge the phone while its off but there is battery icon with exclamation point.
We cannot charge the phone until now. pls help

I have managed to charge it like 35% in 6hours, only samsung can help us now. You can report bug in Samsung members app.
I am so relieved to hear that the issue is more widespread than I thought, it might mean that Samsung will have to take it seriously, I hope they'll publish an update soon
Also, a soft-reset (from the phone settings) + a factory reset (from recovery mode) did not fix the issue, don't bother trying if you were thinking about it.
I rolled back to August patch with Odin same thing happens i guess its hardware related...:crying:

Nice! So that means that it's a software issue?

Glad to hear that, I'll try to get in touch with Sammobile, they might help us raise this issue to Samsung. Thank you for confirming, It would be really nice if we could get other people with this issue to show up in this thread
I also can't charge properly which is a pain. Was working 100% before I updated the firmware
No idea if they gonna fix this soon, there is a way to roll back with Odin. It's safe I didn't had any problems.
I have a same issue with this weird update. I want to roll back the updates but how and where to download the previous updates manually. :'(
You can see instructions on sammobile or here on XDA.
According to a user on Reddit, he/she can't find the update (said they were still on A505FDDU2ASJ1, and the culprit update is A505FDDU2ASJ2), it appears that Samsung has pulled it out from the servers, this must mean that they're aware that it's causing issues!
That's nice to hear
