S9 Plus freezing and rebooting (SM-G9650) - Samsung Galaxy S9+ Questions & Answers

Hi guys, how are you? I'm having a problem with my S9+. I'm from Brazil and have the SM-G9650 model. My phone was working fine, but since last days, it randomly started freezing and rebooting. There isn't any specific task that I do when this happen, might open Spotify or Netflix and the phone freezes or be just scrolling through the home screen and this happen. Even with the phone locked on my desk, sometimes it reboot itself.
Already hard reset the phone, worked for maybe half a hour before started crashing again.
Any tips for what can I do? I was thinking to download the firmware on sammobile, but is it worth? The download is painfully slow.

I had the same problem and I'm on Tmobile in the US . My messages was freezing non stop. I had to do a hard reset and now all is fine . When my upgrade is available I will be switching to OnePlus because I'm getting tired of NO root on Samsung . OnePlus 6T has root !!

SGS3 keeps rebooting randomly

My SGS3 works just fine for 2 weeks, until now.
Suddenly, it keeps randomly crashing and reboot into samsung s3 logo screen.
Oh, I have tried different roms (and stock rom also) but the crash still happen.
I also have tried wiping cache, dalvik, clean install, removing external sdcard, and restore factory setting. But none was effective.
Any ideas?
I had a similar issue with my Atrix and it turned out to be the SIM Card. Had it replaced and no more random reboots. I figured this out by checking the panic dumps...maybe there is a similar way to check this on the SGS3

Thanks for the response.. I tried it just a moment ago without sim card, and it still got the random reboot..
Any other people who got the same problem?
Is the phone unusually warm? The phone will automatically reboot if it overheats, but that wouldn't normally happen unless it's been left in the sun or overclocked.
I can get mine to go into a reboot loop if I play Asphalt 6 while outdoors, but the problem goes away as soon as I let it cool off for a minute or two.

yes, the phone (when i use it) is usually warm, but my phone also crashed while not in warm state.
but this crashing-reboot problem just show up after 2 weeks of normal (and not any crash experience) usage.
this crashing problem show up after i played temple run btw (not sure is relevant)

Sorry to hear that man. Had a SGS with same issues. maybe Samsung has hurried releasing galaxy S3
I'd factory reset and only put on the important apps you use. Depending how long it takes for you to normally get a reboot you can slowly add new apps back to narrow it down. I had the same problem last year and thought I had a bad sgs2. But it turned out to be dolphin hd browser at the time that caused it and haven't had a reboot in a year. It could be something similar in your case. Hopefully its software related and not hardware

i just tried flashing normal ROM, after booting to "get started" page, approximately 3~10 seconds, my sgs just rebooted over and over again, until it show only black screen with battery icon on it (i think it may be charging animation while the phone is turned off).
ahhhh this is driving me insane!!
update : i just flashed hypergalaxy ROM and currently it is stable and not experienced crashing (yet ).
i'll give further report later today

Have you tried reinstalling FW with Odin? If yes does it still reboot after a factory reset with nothing installed?
yes, i have tried flashing stock rom using odin a few hours ago, but the crashing still happen.
my sgs3 now stuck at boot-standby5sec-crash-reboot loop.
so, i decided to bring my sgs3 to samsung service center tomorrow. hope they will replace it with a new unit
UPDATE : Samsung replaced my new SGS3 with a new hardware (not sure new device though, the flash counter reset to zero )
the problem seems to be hardware related
thanks for all your reply to my problem

I am having the same issue, I've had my phone since Saturday (6/23/12) and it crashes, reboots, apps crash, internet crashes, email crashes, etc. I can udnerstand a lot of apps may not be updated to ICS.. but no matter what I do.. everything crashes.. It's a bit ridiculous. I am a prior iPhone 4S user and am probably going to return this phone. I can't do much without it crashing or the screen freezing.. not being able to do anything for 2-3 minutes, etc. And they couldn't port any of my numbers from my prior phone because they didn't have the software update to do so yet. So overall, bad experience with the Galaxy.. and maybe I should have waited longer before buying this phone to work all the problems.

I'm very sorry that u have these problems.but there will always manufacturing faults when making so many units.only one thing to do,return it and get a replacement.when u get a fully functional galaxy u won't regreat it,it's a awesome phone.Samsung usually replaces the phone,so I think they will do the same in your case.anyway best of luck
After all the problem I've been through, finally I send my phone back to samsung service center.. they tried to reinstall stock rom several times, and in the end, they change the IC board to a new one.. and it does solve my probs..

[Q] Phone Freezes Randomly

I was using unrooted phone and official firmware for almost 6 months.
After upgrading from 4.1.1 to 4.1.2 OTA Update, Phone started randomly freezing while using and I had to hard restart it every time or pull out the battery, it usually happened when i was in Gallery at first but then just randomly any application or even homescreen. This kept happening for almost 2 days and I was so annoyed by it, I decided to root my phone, I have tried various ROMS, Freezing is of course less frequent but still it does freezes once in a while.
Can anyone help?
Thanks in advance.

Sell it fast before it dies, and get a 32GB one, that sounds like is getting a SDS soon.

GT-I9300 UI stucks randomly

Hi Everyone,
Recently my phone got crazy!
I used it as stock for a long time, until 3 weeks ago when it started being slow (a few weeks after updating from 4.0.4 to 4.1.2), crashing and getting stuck a lot.
I did a factory reset, not before I rooted it and backed it up with Titanium Backup. That's where things took a turn for the worse.
The factory reset didn't solve anything. Phone kept on crashing.
Next I tried to install a custom ROM (Samsung JB based) and a custom kernel. UI responsiveness got much better, of course, but it didn't prevent the phone from crashing. Tried different kernels and still, nothing.
Yesterday I did a full NAND wipe using ODIN and reinstalled everything using HydRx-D ROM. Things actually got a little better, and the phone UI gets stuck much less frequently.
Still, this is very frustrating, and I can't find a solution anywhere.
I'm attaching a logcat from this morning. The phone worked perfectly for 2 hours straight. Read a few articles, made a few phone call - nothing out of the ordinary. Then it got stuck right after a phone call ended.
Now you probably ask why do I always say that the UI stucks. Well, it always starts with being very laggy for a few seconds and then the foreground app gets stuck, but then I can still swipe down from above to see the notification panel and it always gets stuck on the way down. Also, it mostly gets stuck after a phone call. There was this funny case where I had a phone call using my bluetooth headset, and the phone actually got to BOOT SCREEN while I was still talking. When I finished talking, I had to hard reset the phone to get it work.
I'm really lost about this. If it was my PC I'd definitely know what to do about it, but my experience with Android ends with this phone, my TF101 and a couple of other phones/tablets I got to play with.
Thanks in advance for everyone who's willing to help.
Re: GT-I9300 IU stucks randomly
This unfortunately sounds like the kind of thing that happens before the sds strikes.
Will have a look at the log but I'm no expert in these matters,I suggest you read the sds thread and compare symptoms

Help: Galaxy S7 Edge freezing and shutting down randomly.

Hi I have a galaxy S7 Edge (SM-G935FD), I have been using it for 2 months now, phone was fine in the beginning but couple of weeks ago it has started freezing and shutting down randomly and it wont restart until I press power, home and volume down buttons simultaneously. I have cleared the cache partition and factory reset the phone but to no avail, even installed the factory firmware from smart switch. Please help if there is a solution to that. Please.
If you've done all of those steps and still not working, then you might look into making a warranty claim.
The problem is that phone runs fine most of the time but shuts down randomly, got it checked through the warranty company but they say everything is fine. Don't know what the problem is, it was fine in the beginning.

I would try a different / earlier version of the firmware then. Smart Switch can't do that, but you can use Odin.
ok, i will do that asap and will let you know, thank you so much for the help btw can you pls guide me which firmware is the cleanest and most efficient of them all, if you would know?

LG G2 Mini (D620) lagging and stuck in LG logo after several flash attempts

Hi, I'm new in this but I'm also desperate for help. For starters, I live in Venezuela so it's a bit troublesome to visit a proper tech service and stuff. Well, as I said in the title, the problem with my phone is that it keeps getting stuck in the LG logo. I've already flash it several times, but this solution only seems to work for a few days. I'll explain the problems in a chronological order
1) I dropped my phone in january and the screen broke, so I bought a new one along with a new touch screen. At that time, the only problem that I had was that, even though I had a SIM card in my phone, it didn't have any mobile network signal. I tried many things but gave up on that and the problem's still with me
2) In an attempt to fix that issue, I factory reseted my phone and since that time I got the feeling that something was off with my device but I dind't pay attention to it cos my phone was working appareantly fine
3)After that my device started to get laggy and I tought it was the battery because sometimes it was at 87% and when you turn it off and turn it on again, the battery was at 67% in an instant. It wasn't that bad so I kept using it like that
4) Sometime around last month my phone reboot itself (it was usual that when my device got reaaally laggy it reboots itself). The problem was that it got stuck in the LG logo so I look for solutions and end up flashing it.
5) It worked for a few weeks but the cycle started again. Laggy and then stuck in LG logo. I bought a new battery (wich works fine) thinking that this would solve the problem so I did a factory reset, flash it and then turn it on but the problem still didn't go away.
I'm desperate for help cos I need my phone to work and since I live in Venezuela, I really need the money and obviosuly, I can't afford to buy a new device. Could someone help me?
A little note here. I tried upgrading the software using "LG Mobile Support Tool 2014" but the app shuts down before downloading the upgrade. I don't know if it's due to my laptop being really old (Acer Aspire 5920). I know I have A LOT of troubles but I'm in need of a friendly help!
