[Galaxy S II Q&A, Help & Troubleshooting] Thozi:
I'm positive that the Dolphin HD and SD Card issues are not related to each other.

- Bought my SGS2 in July 2011 with 2.3.3

- Dolphin HD never caused any problem's (because system ran stable)

- i also have and had ~300 Apps installed

- Device is not rooted, not has it been flashed with a custom firmware

- I use a Toshiba 32GB Class 4

- I use a second (1800mah) accu pack, which i carry in my pocket and swap multiple times a day, whenever power goes below 15%

That's the facts so far... until last week, after swapping the accupack - i encountered severe problems while rebooting - and i mean severe

.

Basically the device kept popping up massive notifications, informing me that

pretty much every single process kept crashing. I wasnt able to click them

away as fast as they were coming. Without giving me a chance to do anything

but clicking away notifications, the device then completely stalled and rebooted

into the SIM unlock prompt. Over end over.

Not having done a backup for many month, i then updated kies - and after

many manual resets, including removing the battery many times.. the system

finally came to a somewhat "stable" position, where it allowed me to backup my

data.

I THEN updated to 2.3.5 via KIES (Baseband KI4, Kernel 2.6.35.7-I9100XWKJ1-CL647431 root@DELL150 #2, Build XWKJ1).

I really hoped this would "fix" the device. Since the crashed and rebooting

occured BEFORE upgrading to 2.3.5 - i can't blame the FW for the rebooting.

However, the Update didn't fix the problem. The SGS2 then rebooted anywhere

from "right away" to some 20 Minutes of buggy operation. I began my google

search and it brought me here.

Dolphin was my favourite Browser, but after reading all your posts, i was

convinced that there might be something to it... so uninstalled my beloved

Dolphin HD, took my device and visited a friend (was stable for 4 hrs).

Back@Home, i changed the battery (which wasnt neccessary, cause it was still

at 69%, but since the rebooting usually occured right after swapping the

battery pack, i thought it's a good idea to verify the idea, that Dolphin was

causing the issues.

But swapping the batterypack brought up another crash & rebooting sequence!

So to me, Dolphin can't be blamed.

I took out the SD Card (before i read about it in here) and violá - the System

booted flawlessly. The Batteryswap is performed without a problem. System is

running stable and everything is fine... except i fell from 48Gigs back to 16...

which is unacceptable of course ;)

I put the SD into my notebook to check the SD-Card for any bad sectors... any

test came up "clean"... so no errors here.

It makes sense to me that app2SD may cause the problem here. I don't mind

sharing the Info of which programs are outsourced to my SD Card:

another folder on the card "only" holds the gameloft gamedata (about 3Gig)

The 32GB Card still has 7GB free. The rest is Video and Audio only.

(my) Conclusion:

Removing the SD Card fixed the rebooting, even with Dolphin HD installed(!)

However, I now need to experiment on WHY the SD Card causes the massive

crashing of processes... maybe i can upload a video of the processes crashing

to youtube and follow up in here.

For any suggestions on how to "fix" my SD Card to work properly in my Device again,

I'd be thankful.

I hope my post also helps somebody with similar issues.

Appendix:

(Still hope ICS 4.0.x will solve all of these problems... but i'm doubtful)
