Lags, Freezes and Force Closes after Device Factory Reset - T-Mobile Samsung Galaxy Note 8 Questions & Answers

Ok so I've never attempted to root my Note8 or modify it in any way. It's paid off and was going to sell it since I have a nother one via the BOGO deal with T-Mobile. I did a factory reset to prep the phone for the new onwer. I left it on the setup screen without ever going further. Today the buyer backed out so I decided to give it to my sister. Shes had the phone for only a few hours and hasn't even downloaded an app yet and the phone is acting very odd. It freezes often and backs out of any open app. Apps freeze while using them then force close. Stock apps. Facebook being the worst and it's a system app so I can't so much about it without root.
It lags, skips, freezes and has gotten pretty hot.
I did not modifying at all. No firmware reflash or anything. Just a simple factory reset due to just selling the phone. It had no prior issues before the fact.
Any help would be greatly appreciated. It's a fairly new phone and all I see is battery problems that I have yet to experience on either one of my Note8s.

Do not another factory reset. If that does not help try reimage it.

Just root? Or custom ROM as well? Maybe go back to Stock Unrooted.

My S2 is sometimes jerky/unresponsive

Couldn't see anything about a general jerky S2 here - hope I'm not duplicating something...
I have a T-Mobile UK Galaxy S2. I've had it a week and its my first Android phone so I'm not super experienced with it. I am rooted running:
Android version 2.3.3
Kernel KF3
Build Number BOKF3
About once per day the phone becomes very jerky and unresponsive. If I am navigating the menus or flicking up a long menu screen the motion isn't smooth. Similarly if I am using Swype my swipes often get interrupted by this freezing motion. The phone just doesn't keep up with my finger and in end up with an incomplete word. In the web browser it takes a while to register my finger on the screen and often when I try to scroll, I end up clicking.
The problem goes away if I turn off the phone and restart but I have not been able to find a way to resolve it without doing this.
I have tried: ending all apps; clearing ram; using advanced task killer.
Only a reset seems to make a difference. I can then be OK for the next few hours, but I think I've had this problem at least once per day since I've had the phone.
I've not notice it being triggered by any specific app.
Can anyone help me fix this? Is there anything I can install to see what might be going on? Anyone else had the problem?
Any help really appreciated
Backup all data and factory reset as first step ..
jje
Can you advise what my best way is to do that given my current situation.
I didn't make a backup pre-root. Is this a problem? Is it just a matter of connecting to Kies to do the factory reset? Or do I need to use other tools/locate the original kernel.
There is nothing on the phone that I need to back up (other than a few paid apps which I believe I can use Titanium (free) to backup right?
Thanks
Update: Backed up my apps with "file expert", did the factory reset, downloaded fresh copies of only the apps I really wants and so-far-so-good. Thanks again.
Problem seems to have reappeared. Was using the phone this morning and it became all jerky again. Can anyone suggest other things I can look at?
thanks
If you are still on old KF3 ROM, consider upgrading to KG3 or wait few days KG6 will be released.
I see signs of kg6 in the other forums. is the version I need out now?
Im really keen to gert this shorted as the jerk is driving mr madit seemslike a pylsetjayfreezes the phone. If I am in my contacts list i can flick the screen and make the list scroll fast down.but it stops for a second then continues on its way.normally when it happens it happens s second time just when the scroll is slowed right down. Its like there is something running on the phone causing it every 1.5 seconds.
Im worried my phone is defective as none else seems to have this problem.
Any pointers to three correct kg6 our other solutions much appreciated.
Cheers

Well a couple of months later I still have the same problem. I'm now running KH3 and the problem is persisting. I've also noticed that the 'jerk' interrupts the filming of video so anything recorded while it is happening ends up with little skips in the video and out of sync audio.
I've also tried an app from the market "fast reboot" but that doesn't solve the problem. I still only get a temporary fix by turning the phone completely off and then back on again.
Does anyone know the process for returning a phone to T-Mobile UK? Am I going to be without a phone for ages? A friend who also has a SGS2 on the T-Mobile network but purchased from Carphone Warehouse is convinced it that it is the fact it is a T-Mobile direct phone that causes the problem... but they can't all be like this???
Otherwise, is there anything else I can try to troubleshoot what might be happening. There must be *something* that starts running on the phone that causes this jerky behavior but I just don't know how to identify it.
Any help much appreciated - thanks!
Well, that's definitely not normal. Sounds like an hardware issue to me. A friend of mine got his SGS2 from T-Mobile Shop Austria (with branding) and he doesn't have this issue.
- Maybe your homescreen is overloaded with widgets. Try to remove some Widgets, like Program Monitor (caused me some jerking).
- Do a factory reset (settings/privacy/factory data reset). don't forget to backup your data.
- Try to flash a different Rom (full wipe) with Odin, like KI3 (2.3.5) or a Custom Rom . I'm personally using CheckRom Revolution and I'm really happy with this Rom. However you'll lose your T- Mobile branding and your warranty, if you root your phone. Don't forget to backup your current Rom and buy / use a USB JIG to get the warranty back, if it doesn't solve your problem.
Well, I personally doubt that any of these methods will help your problem.
If nothing helps, then talk with T-mobile ... maybe they'll instantly replace your GS2 with a new one, if you explain the situation in detail. Try to put some pressure on them^^ Otherwise you have a couple of weeks to wait, because T-Mobile will most likely send your damaged phone to Samsung.
good luck.

Need Help...Note 2 Keeps Freezing

I'm hoping you guys can help. Been a long time lurker here and am going to be buying my Note 2 at the end of the month. But my wife purchased one the day after Christmas, and since the new ota update in January, her N2 has been freezing a lot. Sometimes you can get it to turn back on, but than it freezes and reboots on its own. Most of the time she has to do a battery pull to get it to come back on. It happens about 5 times a day.
Verizon had her factory reset it, but it still has the persistent problem. Best Buy took a look at it and they couldn't figure it out. She is hoping we can figure it out before we have to send it back in, which would suck because she would be without a phone that she needs for work for a week. Not to mention Best Buy and Verizon stated that if it does need to be replaced, that it would be with a refurbished one. Which I am not at all too happy about that. Hoping you guys can help me out.

I'm thinking it's an app she has installed most likely also power saving modes not on is it? Tell her to root it and all her troubles will go away

I tried to get her to root, but this is her first android device, she's had nothing but the Iphones prior and is nervous about doing stuff like that. It started after the last ota update, and the only recent app she downloaded was Unblock Me. Since then all this has been happening, and we already uninstalled Unblock Me suspecting that was the culprit. I have it on my phone with no problems.
yes, she does have power saving mode on

turn it off and see if it helps. that strange behavior is most likely caused by an app. Can you screen shot or list what apps she has on her phone?
Yeah I'm thinking it's power saving mode turn it off see if she can make it through a day without it freezing. You don't need power saving on a note 2 battery life is great without it unless your wife is like most females and always forgets to charge her phones

Here's the list of apps she has downloaded. She hasn't downloaded anything recently except for that Unblock Me and the ota update. She said since yesterday Verizon had her factory reset the phone. She reinstalled all her apps, and it still kept freezing. When in froze this afternoon and it shut down(didn't reboot), she took it strait to Best Buy to have them look at it.
The guy fiddled with it, and it was freezing and rebooting on him as he was messing with settings. He told her it probably needed to be sent in. She doesn't want a refurbished phone if they replace this one, so we are trying to figure it out. But since that visit, the phone has not froze on her. Weird.
Should we uninstall all the apps and install one by one each day to see which may be causing it?
Did you turn power saving off and it still freezing?
Sent from my SCH-I605 using Tapatalk 2
when I checked it, it was already off. I know she had it on, but don't know if the BB guy turned it off or if it was turned off by the factory reset.
If it's still freezing with power save off then I would factory reset it then install the apps that she must have for day to day use. Then give it a day and install the other apps she wants.

This. Factory reset is your last option other than rooting (and flashing a custom OS) or sending it in.

I totally agree. :good:
Phones normally only freeze when the ram runs out. Is there any app misbehaving and sucking up all the ram?
I had some what i thought were random reboots the first few months with my N2. These I discovered were caused by carry the N2 in my back pocket of my jeans! Every time I bent down to pick something up or to tie my laces it would reboot!! I would just hear the start up noise comming from my pocket. Make sure she doesn't put it in her skinny-jeans back pocket.
Thanks for the suggestions guys! It froze again this morning, so we are going to factory reset and install apps one by one each day to see who the culprit is. Hopefully its an app doing this.
I have been experiencing EXACTLY that and hqve tried most of the remedies. However this only seems to happen at work which makes it somewhat difficult to actuwlly sot down and diagnose the problem.

I have been reading about this issue from a lot of people with the s3 & note 2 on forums. I honestly think Samsung/Verizon sent out a bad OTA due to rushing to close the security loopholes. I refused the ota and found a way to permanently defer the update and have not experienced any reboots or freezing.
From my previous/recent experience Verizon will absolutely not help you at all, they are worthless 99% of the time. All they are able to do is tell you to factory reset it(if they know how) and have no actual clue how to fix the devices. They will even 'call' the software support for you but will still tell you to either factory reset or do a return. I am disgruntled after they destroyed 3 phones (Droid Incredible) in my family after pushing out horribly bugged OTAs that left the devices useless. I confronted them and they flat out refused to take ownership of their own software that they pushed out. I still feel like they should be sued over what happened.
Good Luck!

Yeah leave it to VZW to fix one thing and introduce a worst bug. I had a Motorola bionic that kept losing signal every 20 minutes or so then version sent out an update damn phone would drop signal every 30 seconds or not even connect to data. Basically rendering the phone useless. Worst part was Motorola had the bootloader locked down so tight there was no good development. At least we have good development for our note 2

Users should legitimately have a lawsuit case against Verizon. They are essentially forcing you to purchase a new device because of something they did. When I confronted them they straight up told me to buy a new device. Devices should work indefinitely theoretically and they are causing irreparable damage.
My note 2 was having major battery drain issues so I got my self back to pure stock like day 1 and I went ahead and updated with the ota so I will see if the random freezing / reboots pick up or not. I already noticed a keyboard bug where it pulls up a numerical only keyboard and wont allow me to type letters unless I reboot.
Did anyone solve this? I'm in the UK and very recently got my ota update. Since then I've been getting multiple daily resets and freezes. Can't say whether it's due to the ota update or some software I've been using, but the crashes are certainly pretty new and very annoying.

Convinced now its the update.
Anyone know how to reflash to 4.1.1

Mega I527

Hey Guys,
I just switched to the Mega from Note and love yet but I have a small problem! I rooted my phone a month a go and never had a problem. Two days ago, I could not send out text messages but I could receive them and make all my calls. I did a factory reset and everything went back to normal. Well it happen again last night so once again I did a factory reset. It's working now BUT all the bloatware is not on my phone. Can anybody tell me why?
After I did the first factory reset, bloatware is there and after the second factory reset, bloatware is gone. Is that normal? Not really complaining about it, it just seem strange. Any tips or any replies, I greatly appericate it. Thanks

When you erase stock\branded carrier apps they are gone forever. thats why you should back them up just in case. I deleted an essential stock carrier app without backing it up and found out later that i needed that app to enable wifi calling on my phone. i couldent find a downloadable replacement so I screwed myself on that one. be careful erasing stuff.

It bypassed the att bloatware install package which can happen when doing that. Actually can happen with kies the exact same way which is why I dont recommend using kies for firmware related issues. Someone in another thread had similar issue where they did firmware reinitialization and then tried to do ota update which caused bootloops due to kies bypassing att package then device didnt know what it was doing. I would be cautious running the device like that because at any moment its possible to bootloop.
As far as the general issue with the device it sounds connected to the issue of bloatware disappering. I would guess you may have a bad file somewhere causing infrequent issues. If possible I would highly recommend download stock tar.md5 file and run it in odin to get a fresh run. It wont delete any of your information or apps.
ALSO NOTE BY DOING SO YOU WILL NEED TO RE-ROOT. Even if it says it is root again.
*used att as just an example, all carriers have their own "package"*

Help for a laggy phone

What do you suggest to fix the lag in this phone? I updated my wife and daughter from a S3 to a S5, but honestly I can't say that this phone performs any quicker than the S3 did. I've rooted the phones and Titanium'd some bloatware but I'm still and ends for getting this phone to respond quickly to actions. Bringing up the camera is slow. Sometimes just getting it to respond to a touch takes several seconds.
I don't want to get anything quirky that my wife won't understand, but I'm frustrated watching her trying to get it to respond quicker. Should I be rebooting it daily? Is there something running that should be deleted? Should I just go to another firmware? Should I get another phone?
Thanks for suggestions.
Try a factory reset and wipe both caches.

S21 crashing/rebooting 1-2 times/day. Any tips on troubleshooting?

I have as SM-G991U (256 GB S21 US version, stock everything but using Nova Launcher) that is randomly freezing/crashing then rebooting on me 1-2 times/day. Does android have any kind of crash log I could look at to try and figure out what's causing the problem? On the samsung forums, their support reps suggest running in Safe Mode, which I have, but it's not very useful because I can't reproduce the problem on demand and it usually happens 1-2/day, but sometimes less, so unless I just ran in safe mode all the time, that wouldn't tell me much. Plus, it would only tell me it's an issue caused by one of a hundred or so apps which, again, is not helpful.
So I'm hoping there is a crash log or something somewhere because I have no idea what triggers the crashes. The other night, it was sitting on a wireless charger, the screen wasn't on, then all the sudden it rebooted. It's not specific to any app or anything I'm doing. If there are no crash logs (which would be frustrating and disappointing), any other troubleshooting ideas are welcome!
Look for a memory leak. Typically a poorly written 3rd party apk.
Try clearing system cache.
Make sure auto restart isn't enabled...

Hi mate
For logs info check here and here
You can always flash firmware , using home_csc , to avoid factory reset the phone , if the problem is system related it will help
If is app related
Try booting in safe mode to see if problem goes away...

Thanks! I'll definitely try these out. I tried safe mode, the trouble is it's not really great as a diagnostic because the phone will go from 4-24 hrs between resets during normal operation, and since a phone in safe mode isn't terribly useful, it's hard to keep it in safe mode for long enough to see if that fixed the issue, if that makes sense. And then, if it did fix the issue, it just narrows it down to 1 out of a hundred apps! But maybe I'm missing something. Is there additional information I can find if I run in safe mode that would help suss out the problem?

Is not easy , you just need to be methodic
See if you can find anything useful in the logs first
Reflash firmware , use home-csc , see if it help
Have you notice if the phone fails under any specific circumstances?
If that does not help and if you can really relate the problem with any specific app you may try to freeze or uninstall suspicious app and let it run for a day , Package disabler app is a good option , it is easy to enable or disable app but is not free, you could try this one , is a debloater tool , it allow you to disable app... may be easy that having to uninstall / install by hand
I'm also having the same problem. Had the phone since June, it didn't start to occur until late August, which leads me to suspect it is an update related issue.

I'm glad you posted today, I've been meaning to post again here because I tried troubleshooting and am still having issues. In fact, it crashed twice today when I was trying to send a text message.
I installed one of the log applications (can't remember which one at the moment) but it wasn't really helpful. They didn't seem to catch any information related to a crash even though they were logging data at least twice when it crashed.
Then I tried reflashing using home-csc using ODIN and that ended up soft-bricking my phone (and yes, I followed all the instructions and used home-csc) so I had to reflash everything and do a full factory reset. That seemed to help, reducing the crashes from once/day to once/2-3 days for a few weeks, but now it's back to ~once a day (sometimes more, sometimes less).
So if anyone has any other idea, I'm all ears. When I was reflashing and stuff, I noticed in the recovery mode (or whatever it's called) options that you can look at logs. Does anyone know if one of those logs would have crash-related data or any other ideas of what to try? This is incredibly frustrating, especially that it's persisting after a factory reset. Argh!

So what I tried to do is roll back all the default google app updates. Ex: Android system webview, Google app itself, etc etc. I factory reset it without backing up any apps (but pictures and messages etc), It was working for a few days and then it happened again. Which further reinforces my thinking that my problem is software based.

So I'm curious why you think that means it's a software issue. If this isn't a widespread issue with the S21 and after we've both done a factory reset and still have the issue, that makes me think it could be a hardware issue. Of course, there could be some software incompatibility with an app that most people don't have installed or a bluetooth connection or something, which is why I really want to find a useful crash log (and find it rather absurb how hard it is to find a useful crash log on android, come on guys, it's a mature OS, some kind of crash log seems pretty basic!), because otherwise, it could be a ton of issues and I can't reproduce it. Ugh.
The reason is that the "few days" after the reset and restoring pictures, messages (but not apps) from backup, where there were no crashes at all (where previously it would happen at least 2 times per day).

After the most recent monthly update, my phone has gone from rebooting multiple times/day to once every 2-3 days, which is more manageable but still super annoying. It is incredibly frustrating to me that there are no good tools to troubleshoot a crash (at least that I've ben able to find). Honestly, it's driven me to consider an iPhone for the first time in my life .
My trouble is back... I will be scheduling a fix with samsung soon so I can RMA it
Check the below link. This seems to be a hardware problem which got solved after Samsung replaced the motherboard.
Samsung Restart problem
So I bought this phone for my wife. Since I received the phone, after a day the phone started crashing whatever app she was on and then take you back to lock screen without having to go through a full restart process but it was definitely a restart as you would need to enter your pin again as opposed to fingerprints.
Since it was within 15 days of purchase I returned and reordered another one from Samsung, and to my surprise exact same issue. What are the odds of having two brand new phones having exact same issues.
This leads me to believe it must be a software issue. I just received this 2nd new phone last Friday.
Yeah, I think what I was experiencing was a hardware issue (it definitely went through the full restart process, not what is described in the previous post). And from the link posted by sandystays above, it looks pretty common. I contacted Samsung support and was not impressed at all. They walked me through a number of troubleshooting steps that weren't helpful then had me take my phone to UBreakIFix. I did, they ran a diagnostic and their tools couldn't find anything wrong so they said Samsung should replace it.
Contacted Samsung, told them I had taken it in. They said I needed to take it to a technician (again, right after telling them I just had). They then said, oh, you'll have to mail it to us and you'll get your phone back in 7-10 business days. Their suggestion for what to do for a phone in the meantime? Buy a prepaid phone then return it when I get my phone back (which a) is unethical and b) wouldn't work anyways since they're locked). Ridiculous. They also admitted that this is a very common problem, so I asked why they just won't send me a replacement device if it's so common to which they had no real answer, just "that's our policy".
Eventually, I contacted T-mobile (my carrier) and was very pleasantly surprised. After me telling them the issue and the steps I'd taken to troubleshoot it, they sent me a replacement phone (recertified, but still) that arrived in 2 days. WAAAYYYY better than Samsung. The entire process made me a bit jealous of my wife's iPhone. If she had had a similar issue, we could have taken it to an apple store and not had the whole "our policy is that you have no phone for 7-10 business days" nonsense from Samsung AND the backup and restore process is still way better on iPhones than on any android I've ever owned. How there is no easy and reliable backup/restore mechanism on android after so long is beyond me.
Bottome line: if you have a similar issue, it's very likely a hardware problem (my replacement phone has been fine for 3 days now). And avoid Samsung support if you can!

On the second phone I still have the 2wk window to return. I am contemplating if I should just return altogether. I had bought an s21 Ultra as well and that seem to be working OK.
Two s21+ phones with same issue, what are the odds of hardware problem? But what if it is the entire batch that is bad.

Your issue sounds different to me. Mine definitely fully rebooted, I have no idea what is going on with yours, it sounds like your crashes are locking the phone or something, that could definitely be software. Good luck!
