I was thinking the same before, for me it always seems to be worse when my device dips below 60 percent, triggering the battery saving and then when I charge it and it switches back to optimised, it seemed to slow down more and more.
[Samsung Galaxy Note 10+ Questions & Answers] Kuro Miku:
I've had that setting turned off for a while. The issue was still there. I recently turned it on and the issue is still there, unfortunately.

I was really hoping the February patch would fix it.

Factory resetting would be useless, right?
[Samsung Galaxy Note 10+ Questions & Answers] talexop:
I have attached the graph during the weekend. I do not think the issue is related to adaptive charging. I made a tasker task to stop charging when battery is full (not really but the system thinks it is not charging) . My finding is that during charging there is a small leak but after that now the leak stops even if the phone is still charging.

I think it definitely has to do with memory leak during charging AND when it is fully charged with the cable in. It seems that has nothing to do with AOD, disabled apps...

In the graph you can see also that during fast charging the leak is smaller because the charge is done faster than slow charging!

Let's hope it will fixed in later updates!

Has samsung even acknowledged that this is happening and they're aware of it?
[Samsung Galaxy Note 10+ Questions & Answers] Gary02468:
Apart from mainstream-publicized nightmares such as exploding batteries, disintegrating Folds, and indiscriminate fingerprint sensors, I'm not aware that Samsung has ever officially acknowledged a problem with their phones, especially before it gets fixed.

I have created a new tasker task that disables charging when you plug in the charger. I also replaced Nova launcher with samsung one and enable the new gestures. I also make sure that I won't use the back button. The results are good.

[Samsung Galaxy Note 10+ Questions & Answers] raul6:
So, what is it, charging or 3rd party launcher or both?
[Samsung Galaxy Note 10+ Questions & Answers] p50kombi:
I'm no expert, but if it was Nova, wouldn't you see the memory consumption of Nova increase instead of kernel memory?
[Samsung Galaxy Note 10+ Questions & Answers] talexop:
I do not think it is nova.. But I did this change because I wanted to use the new gestures of android 10, which do not work with nova!

But I do not know if it is the charging or the gestures or related to not pressing back button to exit app!

I will try to figure it out.

Unfortunately it need a lot of time because the problem arises after hours!
[Samsung Galaxy Note 10+ Questions & Answers] dgh1981:
I've been attentively watching this thread as my Galaxy s10+ has had this issue since the Android 10 update. I had to setup a daily 3 am reboot, otherwise the phone lagged so badly it was unusable. Wiped cache partition multiple times as well as factory reset twice--issue still present. I see the same high kernel memory usage and aggressive app closure. I hope there is a patch for this soon as it's very frustrating and the issue didn't happen with Android 9.
[Samsung Galaxy Note 10+ Questions & Answers] freeza:
This is interesting, as my N9750 (Snapdragon) unlocked/rooted does not have memory leak issues
[Samsung Galaxy Note 10+ Questions & Answers] dgh1981:
Could it possibly be a 3rd party app that we all have installed in common? If there was a fundamental issue with the firmware wouldn't it be more widespread? Has anyone with the issue tried to run in safe mode for over 24 hours to see if leak still happens? I haven't tried that yet.
[Samsung Galaxy Note 10+ Questions & Answers] talexop:
My latest finding is that the problem occurs when swap gets full. I compared the swap space with note on Android 9 and it doesn't gets full.

You can check swap usage with memory-swapcheck app. After 24h the swap gets full! And can only be emptied with reboot!

When swap is full then kernel starts leaking. The leak is more during charging! But even when swap is not full and the device charges the kernel memory increases! I

Last night with my task disabled I saw the following behaviour.. the kernel start increasing memory during charging 2G increase. The swap increases 1G. After removing my unit from the charger the kernel memory is transfered to swap! So kernel decrease and swap increase!

Seeing the same behavior after installing the memory check app. When swap gets exhausted the phone will lag badly soon after. So frustrating. Installed February update via Verizon and issue still persists. How can this not be more widespread? Could we possibly have faulty hardware that wasn't exposed until Android 10?
[Samsung Galaxy Note 10+ Questions & Answers] talexop:
The last two days I have different measurements. Kernel mem stays low and swap increase but maybe in normal increase...

First I boot my phone to safe mode. When returned to normal mode I saw that some permissions we're disabled for some apps.

Second I unistalled some apps like ccw, naptimes, greenify

And third I disabled some apps you see in the screenshot...

I am not sure which change improve the leak but for sure it looks very good if you compare it with the previous measurements...

Maybe you can check if you have any apps like me and try the above...

[Samsung Galaxy Note 10+ Questions & Answers] jateruy:
I have Greenify too. I will be checking if that is the culprit by uninstalling it and give it a few charge cycles.
[Samsung Galaxy Note 10+ Questions & Answers] p50kombi:
I don't have any app like nap time or greenify. So I doubt it's any of those. sorry.
[Samsung Galaxy Note 10+ Questions & Answers] dgh1981:
Trying something similar. I just disabled almost all of of the 3rd party apps I have installed using package disabler pro. Rebooted and cleared cache partition. Will know if this helps by the morning. Didn't want to do complete safe mode with having so much disabled I figured this would at least be a good way to see if something I installed is doing it. Let you know in am.
[Samsung Galaxy Note 10+ Questions & Answers] talexop:
The leak seems to be random... Sometimes it begins after hours some times after days...

When swap got full kernel jumped from 1G to 3G!! I have attached 3 days log..

[Samsung Galaxy Note 10+ Questions & Answers] dgh1981:
Still no luck with disabling a bunch of apps like safe mode. The leak still happened. Today I decided to factory reset for the 3rd time, but this time I decided to use Odin and flash the latest Verizon build of the firmware. Phone is back up and running and kernel memory is around 700 MB...fingers crossed.
[Samsung Galaxy Note 10+ Questions & Answers] zjhao:
hello

what software do you use for the second picture?

It looks a lot like Adhell3

but Samsung has modified the policy and does not open key acquisition

Thank you
[Samsung Galaxy Note 10+ Questions & Answers] dgh1981:
Okay everyone, big news. I now have 24 hours of uptime since I flashes my s10+ with Odin. Everything is working perfectly. Kernel memory is steady with around 700 MB used and I have no aggressive app switching. Running processes in dev options is properly caching memory.

My best guess is that the OTA update to Android 10 somehow corrupted something on the phone. Doing a regular factory reset didn't fix since the base firmware had corruption. A reflash with the image with Odin corrected. I'll let you all know if something changes but so far so good.

[Samsung Galaxy Note 10+ Questions & Answers] jateruy:
So, not too sure if that was the firmware which fixed the leak. My Canadian unlocked Note 10 haven't got the Feb patch yet but recently a wave of Galaxy Store app updates got my phone into the first 50 hours (that's two and a half charge cycle done) in its lifetime with cached background RAM high up around 3GB (Honestly even fresh reboot haven't seen that high before). Don't know if this is pure luck or the fix were actually introduced in one of the system app update (Galaxy Store has no way to see recent updates after dismissed notification). Anyways, things are looking better than ever.
[Samsung Galaxy Note 10+ Questions & Answers] Kuro Miku:
Same here. After receiving a ton of updates for samsung apps it seems like my phone doesn't slow down at all (S10 Canadian Variant)

Edit: Nvm. I spoke too soon. Still have occasional but less frequent lag. I have issues with ram, it wont remember where I am if I task switch.

This issue is still present in the latest Korean firmware (which is what my phone requires) posted on 08/03. Although the firmware was built on 17/02 so it was not that surprising.
[Samsung Galaxy Note 10+ Questions & Answers] chantoine:
Hi,

i just had this answer from Samsung recently. In french, saying the solution is coming.
[Samsung Galaxy Note 10+ Questions & Answers] razen_kain:
Guys i read the whole thread. I've been facing this same problem with my SD S10. I've updated to the current March security update and can confirm that the issue is still there.

However, i have figured out the issue with my phone through trial and error...

I use better battery stats and gsam battery monitor pro on my phone. Since I'm not rooted i use the adb commands to allow usage stats, dump, etc. For some reason this causes the issue for me. I've tried it 4 different times now. I can use these apps just fine as long as the adb permissions are not set. Phone will go for many days with no problem. Within 8 hours of seetting permissions via ADB, like clockwork, phone starts going haywire. Slow/crashing camera is the first symptom, within an hour it will become useless, and finally reboot itself if left long enough.

I updated to March security update last night and enabled permissions. When i woke up this morning, the phone was hot and nearly useless. I couldn't even get my keyboard to work. After rebooting i uninstalled the two previously mentioned apps, then reinstalled without permissions and everything is still working just fine.

Also, i do not charge my phone overnight and i do not ever charge to one hundred percent (supposed to prolong battery capacity). I only charge it to 80-85% ever.
[Samsung Galaxy Note 10+ Questions & Answers] Nico_2812:
I have read all the thread. I have galaxy a40 updated just today to UI 2.0 and is too laggy, seems that closed apps dont stay in cache. So this apps are laggy every time i open it. With Pie the phone runned smooth. I wiped cache partition as well. I think there are the same issues on the other samsung phones. Ah, the build version on my phone is BTB8 with March patches.

Edit: during the charging, the phone gets hot... It was not happening yesterday with Pie. Obv with fast charging disabled
[Samsung Galaxy Note 10+ Questions & Answers] jateruy:
Confirmed problem solved after uninstalling Gsam and BBS. You sir, are an absolute saviour.
[Samsung Galaxy Note 10+ Questions & Answers] fnf:
I can confirm that uninstalling BBS appears to have worked around the issue. The swap memory usage has been only several hundreds MiB after 3 days of uptime. It still remains to be seen if this issue can be triggered by any other app but it has been a marked improvement (normally my Note 10+'s swap usage would raise to the limit of 2.5GiB in about a day).

That would explain the relatively small number of users who have seen this issue as most people don't use BBS.
[Samsung Galaxy Note 10+ Questions & Answers] Nastrahl:
All battery stats app never worked on my phone.

The first time when applying permissions it's working a bit, then shows nothing like I never set the right ADB permissions.
[Samsung Galaxy Note 10+ Questions & Answers] razen_kain:
Now the question is: why? Why do granting battery stats via ADB cause such memory issues?

---------- Post added at 05:58 PM ---------- Previous post was at 05:56 PM ----------

I don't think it's just BBS. I think it's any app you give those permissions to via ADB commands
[Samsung Galaxy Note 10+ Questions & Answers] fnf:
The memory allocated for the battery stats usage might be the reason for the leakage i.e., every time the app requests usage stats it would consume a bit more memory. This memory would have normally been released once the application frees it, or until the application is terminated but it wasn't.

If what Samsung said earlier in [MENTION=4078157]chantoine[/MENTION] 's quote was true then the issue was: https://android-review.googlesource.com/c/platform/frameworks/base/+/1092357 . However it seems unlikely to be the cause for these reasons:

- The PFD would eventually be collected by the garbage collector.

- The fix was merged in 09/2019, it would have been strange that it didn't make it to the current version of Android 10 considering there have been multiple releases since. However Samsung could have a reason for not keep rebasing AOSP often.

That's correct. In my case the phone was rooted so I didn't do it via ADB. Besides, I'd expect that the issue has only been worked around and the memory usage might still increase slowly if the root cause originated from a common kernel/AOSP service (that happens to be used by battery usage stats but which might not be the only thing that uses it).
[Samsung Galaxy Note 10+ Questions & Answers] razen_kain:
I don't think it's just BBS. I think it's any app you give those permissions to via ADB commands

Sorry!
[Samsung Galaxy Note 10+ Questions & Answers] chamonix:
I can not talk about how GSAM has implemented S10 support but I sure can tell for BBS: the S10 has a bug that prevents access to the internal statistics. Therefore I have implemented a workaround, using the "old" method of accessing theses stats. You can see if the workaround is active by going to "Settings - Advanced - App Permissions". If you see "BATTERY_STATS granted (fallback)" there it means that Samsung has not fixed the bug yet.

Now how granting permissions induces a memory leak in Samsung's code is something that I unfortunately can not tell. I have no information whether this is a general issue or if it is specific to certain models so we can only hope that Samsung get their sh** together and fix the original bug. BBS' code is defensive in that area so if the "original" way starts working the workaround will not get called anymore, showing by the lack of "(fallback)".

Sorry for not having a better answer at the moment, will try to get hands on an S10 again for some testing

---------- Post added at 02:12 PM ---------- Previous post was at 02:05 PM ----------

That is pretty interesting and S10 users should have an eyes on this: https://android-review.googlesource.com/c/platform/frameworks/base/+/1092357

The fix seems to be related to garbage collection in the handling of parcels: these are data structures use in android-land to pass data between processes. Now guess what? Parcels are the structures that are used to pass the battery stats along. Interesting is that this fix has been merge into the source tree in last September so it seems that Samsung does not update their codebase that often.
[Samsung Galaxy Note 10+ Questions & Answers] razen_kain:
Thank you for taking the time to weigh in on this. I can assure you that this will be my last Samsung phone if Samsung does not fix this. I've never had a phone that i couldn't use BBS on. This is ridiculous.

Any chance you could link us to the latest most stable version of bbs that should work correctly?

There's a lot of versions out there, the xda version, pstore version and psbeta version.

Thanks mate
[Samsung Galaxy Note 10+ Questions & Answers] fnf:
The aforementioned issue was in AOSP. It won't be possible for an app to bundle the fix so we'll have to wait for Samsung to merge this fix. As they said that they were aware of it fingers crossed we'll see it in the next release.
[Samsung Galaxy Note 10+ Questions & Answers] SPfuns:
this is not only happen Samsung. My mate 20 pro have same problem(android 10).
[Samsung Galaxy Note 10+ Questions & Answers] Nastrahl:
Of course, if it's an AOSP issue there's a great chance that any Android got it too, and it's unrelated to Samsung.
[Samsung Galaxy Note 10+ Questions & Answers] p50kombi:
I meant which version of bbs we can best use of course.
[Samsung Galaxy Note 10+ Questions & Answers] razen_kain:
I think what they're saying is it won't matter which version you use. They will all trigger the leak because the problem is in the AOSP sc. And apparently the fix has already been written but had not been merged into Samsung... Or could be any Android 10 phone that hasn't merged the fix.

... If my understanding is correct that is

I wanted to ask if you have news about this issue being solved in the recent updates?

Thanks.

The issue was actually solved by me by re-imaging the phone using the ODIN methods. In the Android 10 update there must have been something that got corrupt. When I did a normal factory reset, the issue came back. Doing a full flash with Odin solved it.
[Android Q&A, Help & Troubleshooting] unknownuser2:
Hi guys,

i hope some of you can help me.

I want to connect an OBDII cable to my phone. Its a ENET Cable, so I need an OTG/Ethernet Adapter. I have ordered the Rankie USB 3.0 Netzwerkadapter in black. I cant post links, but if you put this in the search in amazon its the first.

But the S7 Edge doesnt support ethernet, or? I cant find ethernet settings. So I flashed the kali nethunter kernel and opened the terminal emulator. With lsusb my ethernet adapter doesnt appear. Can someone help me? I think if the ethernet adapter appear, I can connect it to my car.

edit: Now I used an other third otg micro-usb to usb adapter and now my ethernet adapter appears, its a RTL8153 from Realtek. But how can I use it? I have no ethernet settings.

thanks in advance
[Android Q&A, Help & Troubleshooting] unknownuser2:
Does nobody know an ethernet app or the shell command to get the ethernet working?
[Android Q&A, Help & Troubleshooting] unknownuser2:
Ok, I dont think that here aren't users who know a solution. What I have done yet:

I got the adapter working, but only in terminal emulator. When I type lsusb it recognizes my adapter. Its a realtek RTL8153.

Then I connect my network cable and type: dhclient eth0

for test: ping -n 3 <address>

I get answers, e.g. from google. So the connection built up. But when I go to the browser or google play, it says no connection? I think, the phone and apps depends on 4G or wlan0. How can I force eth0? I need the decisive command.

For the static ip I would use: ifconfig eth0 <ip> netmask 255.255.255.0 gw <gw_ip>
[Samsung Galaxy Tab S6 Accessories] dagrim1:
I have the Tab S6 including official keyboard cover since october, while I also ordered a screenprotector back then it never arrived and I've been using it without in the meantime... I kinda forgot about it, but noticed I have quite a few scratches on my screen now. Most being where the keys at the folding part touch the screen.

The tablet is coming with me to and from work in the bag, otherwise just used at home. Do other ppl have experienced something similar? I''m afraid they gonna blame it on sand (perhaps rightfully so) but it does suck.

I now received my newly ordered screenprotector (plastic and glass) where I put the plastic on for now, not sure what I want to do with the screen in the meantime. Which leads me to, how the hell do you get rid of all the dust. I applied it in the bathroom now, after running the hot shower for a while. Cleaning it with the supplied materials, but still specs of dust...Any tips>?!
[Samsung Galaxy Tab S6 Accessories] nicholb:
I've had the keyboard cover on since release with no screen protector. I also keep it in a laptop sleeve area of my backpack when traveling to/from work. I just took a close look and can't see any scratches. You are probably right to suspect some sand or something got trapped between the keyboard and screen.
[Samsung Galaxy Tab S6 Accessories] dagrim1:
Thanks for the response, yeah... guess that's it indeed. Teaches me for slacking and not putting a protector on it I guess ;)

Put the glass one on anyways and it actually hides the scratches it seems so all is ok for now.
