Help Does your samsung S2 shut down by itself?

I had the same issue for a little while. Turns out it was a bad battery.

This makes me wonder how many other flaky or mildly annoying other issues could possibly be caused by my (suspected bad) battery...

Buttons at bottom not working intermittently?
Turn on delay?
Weird performance issues once in a while?

Tempted to pick up a new one just to troubleshoot.
 
Ok i finally fixed the shit phone i had. It used to shut down by itself, random reboots, wifi problems. Yesterday was the last straw, i was on a phone call and it rebooted, i was pissed. So i decided to take it back to stock, not a factory reset but a new stock flash.
I used this stock image:
androidforums.com/galaxy-s2-boost-mobile-all-things-root/621393-tutorial-return-boost-stock.html
After flashing this, the phone was showing fg31 modem, but then it said there was a system update. I applied the system update, it did it again two more times. Now I'm back to fl24 modem, stock, phone hasn't shut off once all day, wifi connects every single time. I wish i had done this a long time ago. If you are having the same problems, i suggest follow the same steps. Good luck. :)
 
Yes i did. I don't know if the yellow triangle is there or not. Since i have flashed it stock, the phone hasn't shut down once, but the wifi not connecting problem has started up again once in a while.
 
I just posted this in the other thread about this issue:

I had been running FI22 until I reflashed FG31 about a day ago and then updated past FI22 to the latest, FL24. Since then I've experienced this really irritating error several times, and I almost never had that on FI22. So I highly suspect this issue is exclusive to the FL24 build.

Your thoughts?
 
Ok so, I had been running FI22 and never experienced this problem, then I flashed FG31 and updated to FL24 and experienced it several times the first day, then I flashed back to FG31 again and accidentally updated back to FL24 again and the problem popped back up within a couple hours. So now I have flashed back to FG31 once again and updated to FI22 (and no further), and I will let you know if the problem returns.

Long story short, I'm running FI22 again and I don't expect to have to keep rebooting my phone by removing the battery. I believe this problem is exclusive to FL24, then again I've been wrong before.

Hello and welcome to the forums, Dannynica.

Yes, that issue is cropping up here and there with various Galaxy S devices. So far we've not seen a remedy, but several tries seem to give success:

- The battery pull

- The "wipe cache" in recovery menu

- The factory data reset

- The installation of a 3rd party launcher, such as Nova or GoEX, etc.

Good luck. And please remain a member of our community.. post back if you try something. :)

I have tried all this - and it still shuts down or to sleep and you can't wake it up without pulling the battery.
I have had my phone since March 7th and VM has replaced it twice for me - it seems to be an issue that is common - I'll see supposed to have my replacement in a day or two -
They guarantee the phone for one year just call and tell them the problem is there and you want a replacement. They will replace it.

I really like this phone reception is great my previous phone was the Triumph - and reception was poor in my lower floor office - this phone is really great to repeat myself - voice quality wonderful.
 
So you're on your third S2 in as many weeks? I wonder if FL24 et al. is putting the Sprint-based carriers in panic mode - since usually there's nothing wrong with the phone, it's the firmware that's the problem. I wonder if they're sending Samsung back boxes of S2's that work just fine on the factory stock rom. Or perhaps the carriers are instructing the customers to send their phones directly to Samsung immediately after purchase. Maybe they will have to release a further ICS update OTA? Unless you have the Kies app on your computer you're probably not updating to JB - leaving most everybody still on ICS with faulty firmware. Borked right out of the box. I'm sure the carriers have experienced a dramatic increase in defective S2 phones ever since FL24 (and its non-Boost cousins) came out as the final OTA update.
 
The final update is to blame. It makes the phone get "Stuck" and then it powers itself down. Either that or it won't wake up and you have to do a battery pull instead. It's really annoying but I think once they fixed that Exynos exploit, it broke something else.

I've had a lot of customers come to me complaining about this issue and have even experienced it myself too. =[

are you referring to FL24?

I know those exploits are fixed in the GB27 and GC01 and I never have that issue.
 
That's a shame, people are buying the S2, updating it OTA to FL24 without knowing either that GC01 exists or how to flash it (there isn't an update notification in FL24 to get Kies and update to GC01 is there?), then thinking their phone is defective and trying to return it. This will be interesting to see if they push an ICS patch OTA just to stop having to deal with all these suddenly malfunctioning phones, or if they'll be biting a big fat bullet on this one.

Thank you very much for this very useful post. I installed go ex launcher and it fixed my problem. My phone was shutting down 5 to 6 times a day earlier. After installing go ex launcher, not one shutdown!
 
When my customers come in to return their S2, I do the update through the Samsung update tool. Then tell them to give it 24 hours. I have had no returns after that. =]
 
ive been watching mine... S2 TITANIUM GREY (3days old)

seems, when its in 3G mode, it searches for 4G, then it starts to load 4G and dump 3G, but it craps out instead..

i think the MILLISECONDS its need to stop 3g and goto 4g is too slow

ill be in 3G area, then for a SPLIT second it will see 4G and try to lock onto it...
but by then its gone, no more 4G towers, so it trys to fall back on 3G...but its off and stuck in limbo mode.

so its definitely the 3G/4G causing issues.
sure taking the battery out will stop its looping...


theres got to be a fix in the build prop for it.

shut down connections optimizer and keep 4g off and control it manually. You do not need 4g unless you are streaming video, and this will save power on the phone. There is no need to waste power with 4g when you know you aren't in a 4g area.
 
If you've downloaded the software update tool from Samsung, it'll install GC01 (I think that's it).

Anyways, a lot of my customers are no longer having that trouble. I think the Jellybean update fixed it.

thats all well and good...but i cant get that far,lol

it reboots, i unlock it, it frozen...sometimes 1st try other times, like now 5th time and nothing yet.

i had Fl24, ran kies, it said there was an update GC01, so i did it. then rooted it.
stock rom and all..

But i might try GO LAUNCHER, had it for my prevail before.


....maybe its an app running in background that gets the data connection stuck, and frozen...

my apps:

Lookout
google stuff
boost zone (might remove that for good)
a bunch of apps...but i used Android Assistant to STOP apps from starting up with the phone...user apps- not system apps
its recently new phone, so it cant be the battery
but like any other battery i fully charge it and fully discharge it...
 
I used to use Go launcher until it caught the train to bloatville. I would start by seeing if you have the issues with the phone stock with no user apps installed. (rooted is fine). I do recommend removing or at least freezing connections optimizer. I also recommend using Titanium backup to remove the Sprint phone info app (it is an ugly app with nasty permissions, that has no business being on a privately owned phone).

Update - It's back to shutting down 7 times a day despite go ex launcher. God, it's frustrating !!

i saw that sprint info thing, on the other ROM, AOSP or whatever it is...it had issues with my boost Sg2 so i just went back to stock with agat kernel

theres a app...let me find it..
either, https://play.google.com/store/apps/details?id=ccc71.at.free

or

https://play.google.com/store/apps/details?id=net.igio90.androidtweaker.free

both are good...but one has an option to STOP connections made by any app so no spying:)

ive just started playing with since i found it couple hours ago

Unfortunately the Sprint phone info gets set as a device administrator so it can override things, and it would not let me uncheck the administrator setting. Thus is why I removed it all together. It is not a needed app (none of the leaked JB builds had it). According to what I have found on it (Sprint not very forthcoming on it), it is supposedly for things like corporate control of company cellphones. As such, I do firmly believe this has no business being on anyone's privately owned device.

hello everyone, i am new to this site, greetings to all


I would like to know if you samsung S2 shuts down by itself sometimes?

Ahhhhhh, and it is annoying because i have to pull out the battery in order to get it back on!

just pressing the power bottom will not come on

Mine does it. sometimes when i see my phone, it has being shut by itself, i just have this phone for about 3 weeks.

I love the phone besides that issue

Thanks

Yes, that happens to me alot, I sometimes think my phone is haunted....lol Sometimes, it will respond very slow, I try to dial a number, and it takes forever to respond. Also takes longer than I think it should when I pull my face away from the phone to get the dial screen back up. I dont understand any of the info that refers to ''tethering'', ''rooting'' and launchers

Other than that, I love my phone and shudder to think of possible having to do a factory reset. Everything is on my phone!!

Thanks for the forum
