Me too. Random reboot with Dolphin.

I'm absolutely sure it's Dolphin the cause. I've done many many tests about this, since v.5.

It happens even using another app but after browsing.

And without it, no reboot at all.

I really wait for their fix!

Same here. I'm using Dolphin hd and until for a few days ago I got at least one random reboot every day. Thought my problems was facebook, and decided not to install it. Well as soon as I get reboots again I try to uninstall this app and see what's going to happen.

A little input in case it helps. I was running stock Gingerbread 2.3.3 KF4 (rooted) with Dolphin HD for several weeks since I bought the phone without a single reboot. Yesterday I upgraded to stock 2.3.4 KI4, downloaded from the Samsung website, and I got my first ever reboot. I am still running Dolphin HD. The reboot happened shortly after I enabled data and briefly checked connectivity using Opera Mini.

Last night I was looking for a browser that allows me to enter a such specific php/secure page that opera and stock browser simply didn't allow me to open.

So I installed DolphinHD from market (first all-time on this phone). Surfed a little bit (like 5 minutes) then BOOM!!! Reboot...

Uninstalled DolphinHD and didn't get a reboot since...

Cognition 1.5.1
[Galaxy S II Q&A, Help & Troubleshooting] pedestre:
Yesterday I installed dolphin HD and I had a reboot a couple of hours later. Today a new reboot. I've never had a reboot before installing dolphing, so for me it is clear.
[Galaxy S II Q&A, Help & Troubleshooting] cooza:
Ive been using DHD for a while ,2.2.1,.2.2.3(vodafone) then with orange KG5,KG6,KH3,KI3 and now KI4 with OMEGA XT v.3.0 and never had 1 single problem.Id just like to suggest one thing though.Im my case my phone is rooted.After a firmware flash i always boot to CWM recovery and wipe "cache partition" and "dalvik cache".Also in DHD settings i have set clear cookies,cache,history automatically on exit.

meun(on phone)-more-settings-dolphin settings-exit settings.Select all options and press OK.

Never had any problems.Quite possible that the cause could be in "cache partition" as this is the cache which is mainly linked to the market and can give market conection errors also.
[Galaxy S II Q&A, Help & Troubleshooting] geriguy33:
Hey, Thanks for your answers!

-I always used clear cache / history on exit (I cleared all of the other data in the browser settings once a day)

-I tried cache on sd / cache on phone

no solution...

My phone is not rooted, so I can't go to recovery :)

So I think it is Dolphin's turn :)

I'm waiting for a solution, because it is the best browser (for me).

Using LASTPASS without Dolphin is a pain...
[Galaxy S II Q&A, Help & Troubleshooting] cooza:
Although your phone isnt rooted you still have recovery but just dont have the extra options that CWM brings to a rooted device.If you hold at the same "home+power+volume up" it will take you to stock unrooted recovery although it has very few options.If you flash a CF-Root kernel you get root and CWM installed all at once.you could do that,wipe the problem caches(probably "cache partition") and then flash back the official one.
[Galaxy S II Q&A, Help & Troubleshooting] geriguy33:
Thank you for the additional info!

I made a factory reset after my 3. reboot. I think the factory reset also clear the cache partition. It wasn't enough. After installed back (manually! no backup from google) dolphin, the reboot issue started again.

But It was rare! once every 4th-5th day! And not always when browsing.

I think Dolphin stucked at the memory as a service, and used all of the cpu power. It caused kernel panic and reboot...

(I got aproximetly 10 reboots in 3 month - 6 while browsing, 4 after I closed the browser - sometimes after 5 hours. Closed browser -> sleep -> 5h -> wake up -> reboot)

Additional info: I use pure news widget, it has a built in browser for the news feeds. Once the phone rebooted while browsing with this built in browser.

When I uninstalled Dolphin, I disabled this built in browser also, and I use only the stock. No reboot at all after that . It was dolphin for sure!!!

At the Hungarian (I am Hungarian) Samsung Galaxy s2 forum 4 users use Dolphin. Me and an other have problem, the two others have zero problem! We use stock 2.3.4 rom, they use 2.3.5 modded rom

Damn!

I dropped mine onto the concrete floor from about 3ft and I was thankful for my Momax case and screen protector for not having any external damage :(
[Galaxy S II Q&A, Help & Troubleshooting] cooza:
Factory resets only clear user information and not cache partitions but you are correct about the kernel.What usually causes random reboots is a corrupt kernel and its possible that the DHD app has a problem with the kernel for your 2.3.4 stock firmware in your country.If this is true then the next Keis update or hopefully DHD app update should fix it.If you cant wait that long then you can always root your phone which changes your kernel.The 2 that dont have problems are on a different firmware and modded so the problem must be 2.3.4 stock(possibly kernel).
[Galaxy S II Q&A, Help & Troubleshooting] venkatusa:
Hi Guys,

I had the similiar problem. I had it cleared by not moving apps to SD.

SD card is the culprit here. As long as u dont move apps to SD the reboot problem won't occur. Try removing ur SD card and check if u still face problem.

Cheers :)
[Galaxy S II Q&A, Help & Troubleshooting] Mesquire:
that's bad

my HTC Desire never reboots by itself with all possible apps moved to SD card
[Galaxy S II Q&A, Help & Troubleshooting] dikai_yang:
I thought it only happens to me. To replicate the issue: open dolphin, go to settings and delete all data, long press back and exit. Relaunched dolphin, and repeat the above steps. Within several times your phone should reboot.

Mine typically happens when I clear all data.
[Galaxy S II Q&A, Help & Troubleshooting] LocutusEstBorg:
Yes Dolphin HD causes reboots when quitting the browser on SGS2. I find the stock brower to be the fastest since it's HW accelerated on SGS2.
[Galaxy S II Q&A, Help & Troubleshooting] geriguy33:
I don't use sd card, nor app-sd.

All of my apps are in the internal mem.
[Galaxy S II Q&A, Help & Troubleshooting] Mesquire:
Tried it 20 times and no reboot.

Uninstalled it anyway just to see if it was causing my earlier reboots.
[Galaxy S II Q&A, Help & Troubleshooting] 7gismo:
Just to add my 2 cents...Unfortunately I reckon it could be the android 2.3.5 in general which is causing constant reboots of my SGS2. Why? Because once I remove the external SD card - where I had only a few apps moved to - phone stops restarting immediately. Now I have like over 300 apps installed in my phone;) In my case it wasn't DHD related since even after removing this app rebooting didn't stop, but removing SD card did.

Now with the amount of apps I have on my phone, there's no way to keep them on the internal memory only! So I wonder, will moving those apps (that can be moved) stop restarting the phone if I moved them to the internal SD card (11.5GB free once clear).

Just to be clear enough, moving apps to external SD card (32GB class 10) was no problem at all while I was at android 2.3.4.

Again, for me 2.3.5/2.3.7 seems to be the issue here:mad:
[Galaxy S II Q&A, Help & Troubleshooting] arifbsantoso:
300 apps? WOW.......!
[Galaxy S II Q&A, Help & Troubleshooting] r8zer:
I have Dolphon HD and never had a single reboot from having it installed.
[Galaxy S II Q&A, Help & Troubleshooting] 7gismo:
Crazy huh? 80% of them are free market apps, rest bought off market. But seriously I should start reducing them, many of them are alternatives ya know:D

Anyways, I use the external SD for videos, music and personal documents, pity I just can't use it for movable market apps:rolleyes:

I had a week of not using Dolphin, and had no reboots. I then did a few minutes of surfing yesterday on Dolphin and 5 minutes after I finished it rebooted. I'm running stock 2.3.4
[Galaxy S II Q&A, Help & Troubleshooting] geriguy33:
Surfing on xda, I saw that it is a prooved problem of the s2. Many of the users who use app2sd suffer from the random reboot issue... Someone uses the sd only for data storage, but they also get reboot. (Less frequently, but also...)

Dolphin caused reboot is an other problem!

I think the problem is somehow the cahche and data clear when closing the browser.
[Galaxy S II Q&A, Help & Troubleshooting] geriguy33:
Yes, it is Dolphin for sure. But why???

Do you clear cache and data on exit?
[Galaxy S II Q&A, Help & Troubleshooting] 7gismo:
Well, I have no reason not to believe in your case it seems to be DHD causing reboots...however I don't have any problems with it, it's the "apps to be moved to external SD issue" in my case. At the moment I'm in a middle of reinstalling the apps to the internal SD, so let's see what happens next...
[Galaxy S II Q&A, Help & Troubleshooting] itm:
I didn't exit - I just hit the home button
[Galaxy S II Q&A, Help & Troubleshooting] pedestre:
It doesn't matter either you clear de data and cache or not. I've used both options and the reboot has happenned. I've checked that the random reboot always happens if I open a specific application (a spanish sport newspaper application "MARCA") right after closing Dolphin HD.

I hope they can solve this problem because it's the fastest browsing

Edit: If you wait a couple or three seconds before opening the other application, reboot doesn't happen. At least in my tests :)

Still no update from Dolphin :(((
[Galaxy S II Q&A, Help & Troubleshooting] Aincalandorn:
I had the same problem when I had DHD installed, but it still "reboots" (it's more like everything is killed and then restarted. I don't usually see the boot animation.) even after uninstalling DHD.

Could it be ADW Launcher Ex? I can't stand the lack of listing the apps (I don't want my phone to be almost identical to the iPhone). I've had ADW since I pretty much got it, and it's been rebooting.

If it helps, I've got 2.3.3 from Bell Canada. I've also tried with and without the SD Card in, doesn't make a difference. I also don't have any apps whatsoever installed on the SD Card (Or internal storage), it's all on the internal app memory.
[Galaxy S II Q&A, Help & Troubleshooting] Mesquire:
Since my last reply to this thread I have:

1. removed DHD

2. moved all apps to phone memory

3. switched from Go Launcher EX to Launcher 7

it's still rebooting, usually in standby mode. Am considering a factory reset at the end of the month (to coincide with my data billing)
[Galaxy S II Q&A, Help & Troubleshooting] geriguy33:
Sorry about your phone :(
[Galaxy S II Q&A, Help & Troubleshooting] Cintra2:
More than one reason

There is surely more than one cause for these reboots..

I was surprised to find my GS2 waiting at the unlock screen for a sim code a couple of times in the past few days. I am not running Dolphin.. the phone is 10 days old.

I'll get back with an update if I find a clear reason.

Mvh

PS I have the latest standard version 2.3.5 XXKI4
[Galaxy S II Q&A, Help & Troubleshooting] geriguy33:
Thanks!

I know two reasons for the reboot:

-Dolphin HD

-Apps on sd card (sometimes the sd card is enugh for a reboot...)
[Galaxy S II Q&A, Help & Troubleshooting] 7gismo:
Just to add my story in short, my SGS2 stopped rebooting after I uninstalled like 50 apps (most of them were games), atm I have around 250 of them left in total (125 movable still in phone memory, 25 largest ones moved to SD card and the rest cannot be moved to SD card).

I use DHD all the time (I clear cache here and there, nothing regular though) and not a single reboot appeared so far:p

Currently I'm on SensatioN 1.9 and Syiah kernel 2.1.1.
[Galaxy S II Q&A, Help & Troubleshooting] Aincalandorn:
I might have a possible solution: Update to a 2.3.5 rom (I did an unofficial update last night). Dad took my phone today, so I can't confirm if 2.3.3 is the problem for me or not. I've got DHD reinstalled after the update, so I can try to confirm 2.3.3 being the root problem or not.

If the reboots stop over the next couple days, I'll let you know.
[Galaxy S II Q&A, Help & Troubleshooting] pedestre:
Updated. No reboots after installing the new version. We'll see if it is definitive.

Edit: I think it isn't, I had a reboot following the same sequence. I closed the dolphin and very quickly I openned other app: reboot. Of course I was testing the new version and I had to do it just a few times.

is it the same in your cases, guys?
[Galaxy S II Q&A, Help & Troubleshooting] geriguy33:
Yes, rebooted once while browsing, and rebooted once half an hour after closing the browser (the 30 min was sleep time).

It is Dolphin for sure!!!

Installed later version of Dolphin HD last evening after experiencing issues with random reboots. Phone just rebooted, uninstalled Dolphin again, it's the only factor that I have been able to correlate as related to this issue.
[Galaxy S II Q&A, Help & Troubleshooting] mrabcx:
I've had issues with reboots and I even sent in my phone back to a service center as I got so fed up with them. Initially, when I first got the phone it was all fine but gradually it started to reboot randomly. So what did the service center do ? They upgraded to XWKI4 (which I actually already had installed myself), a complete factory reset and a phone functional test (which the phone must have passed) as I got it back.

After getting it back I only rooted it (keeping myself to the stock version) and re-installed all the apps (including Dolphin HD) and .... it worked flawlessly for several weeks. I did have a few reboots but I could trace them to apps (such as Market) and Dolphin (once, on a very demanding page). So overall things were good.

Then later on, I upgraded the firmware a couple of times, tried a few different ROMs and .... voila ... the random reboots gradually came back.

Instead of sending it back once again, I did a complete factory reset myself and re-installed the same non-stock ROM where I was now getting reboots (with CF-root kernel) just to give the ROM another try. And what do I get ? The phone just ran perfectly for more than a week without a single crash (including a lot of Dolphin HD usage) before I myself had to shut it down.

Now, when I have upgraded firmware (I've often used stock ROMs with CF-root kernel) or tried different ROMs (occasionally) I've always cleared the cache and dalvik cache. But to me -and now from my experience- it really looks like that this is not sufficient. Before installing or upgrading (I use Odin) one should probably perform a complete factory reset and format the internal storage.

That seems to be the case for my phone at least as it has worked quite well after factory resets.

Now of course, if some of you guys are getting random reboots and you have not upgraded firmware or installed other ROMs then there must be some other reason for these random crashes ..... bad memory (?) ... but I doubt it's Dolphin unless it crashes when one is using it.
[Galaxy S II Q&A, Help & Troubleshooting] geriguy33:
I don't know how, but dolphin causes the reboots, believe me! I restarted my phone manually yesterday after 550h uptime (dolphin uninstalled)

For those people having Reboot problems with Dolphin HD, please state your ROM and which Kernel you are using.

ROM: Stock XXKI8

KERNEL: Speedmod K2-18-TEST3

Something like that would be easier to understand, then talking about how many times you have to reboot or the frequency of it rebooting.

Those people who are using Stock Kernel, or other Kernels, does you phone freeze when you play a game? My phone used to freeze when I play almost any games. If you are experiencing this problem as well, please try flashing to Speedmod K2-16 and then try to see if Dolphin HD reboots.
