My nexus restarts when i take a picture

Well the camera is slow and acting weird, but even more weird is that it started to restart everytime after i take a picture.
I'm with 8GB microSD card from my old htc HD (which i don't know which class is and if it might be slow and that causes the problem? )
Did that happen to anyone? Or at least do you know what's the class of the factory htc hd card and if that could be possibly an issue?
p.s.
i dont have any other cards handy at the moment to test a bit

I've heard that its good to have class 6 and above. Anything less is creating stability problems for the nexus.

That's completely false. Google wouldn't be shipping the phone with a class 2 card if that were true and that's not what's causing the problem. I don't know what is but best bet is to re flash your phone.

the nexus factory card is class 2?
I guess the factory htc HD cars is also class 2? Can someone confirm that, since i can't find info online.
is there another way to format the card from the phone, other than the "Format SD card" option in settings, which considering how fast "formats" i guess it's just erasing the fat table?
And do you think that unproper formatting might be a problem for android? This is card from a windows mobile phone.
That's where i'm coming from too, so excuse me for the dumb questions

Yes, it's a class 2, 4gb SD Card. I should know since I own a Nexus One. My brother had a memory card formatted by a blackberry but used it just fine on his Moto Cliq but your card may be corrupt. You could use Windows to do a full format and then just pop it back in and it will work. Just right click and click format, I believe.
Also there is no other way to format it via your phone and you can find out your card class by looking at the card there should be a small number with or without a circle around it, that's the class.

Have you called support? They have a knowledge DB that might have something about it. If it's not rooted, you can easily request a repair/replacement, they'll send you a new one.

Now it just goes black screen and after a while says that can't connect to the camera. Seems that i have dead camera and doesnt seem like can be fixed by software....
ah and i dont even have a warranty

You have a one year warranty with Google. Call HTC and explain, they'll help.

yeah well im not even in the countries where they sell, and waiting for the phone to go there and back will be at least a month....

[Q] SD Card for newbies

Hi, I recently purchased a Dell Venue Pro and I am going to get it some time this weekend. The main concern I have with this phone is the small amount of storage. 8gb is simply not enough for me. Perhaps I missed something, but I've been reading through this forum and haven't found a very good explanation for newbies on how to replace the SD Card. I have actually seen some posts that say that they managed to exchange their 8gb SD Card for a Sandisk 32GB micro SD card Class 2. However, I would like to have some guidance and instruction from someone experienced doing this; I wouldn't want a bricked Dell Venue Pro.
Therefore, could anyone please instruct me with a step by step guide on how to replace my SD card without crashing my system and which sd cards are compatible? Thank you.

Believe me when I tell you this will not work. What you will end up with is a bricked phone that needs to be replaced.
If you have a device that was shipped between December and now you don't have an engineering sample, those are the only devices that can actually format the sd card to the proper filesystem and lock the card down in way you'd expect it to.
If you'd like to test that theory, simply replace the card while it's off. Perform a hard reset on the device (the CAM + VOL DN combination does not work), shut it down and put the card back in an SD reader. It won't be formatted and won't be locked down.
You might be able to format the card on a Windows CE machine with storage manager, but the most I've been able to do is get the SD card test to show a 114 not ok instead of a 115 not ok.
After that, if you're lucky, you'll be able to simply throw the old card back in the device and proceed with enjoying your phone with the original SD card. If you're unlucky your phone will not boot.
Food for thought:
In the diagnostics application there is a button for "Service Center" which displays two boxes: Zune and Composite.
When you press the CAM key during boot this puts the device into a "restore" mode that Zune is supposed to work with at some point in the future.
I'm guessing if we can figure out a way to flip the mode to Composite (currently requires a password) that the "test/debug" bootloader will allow us to format the cards properly.
It's also entirely possible that the reason the engineering samples work and the retail devices don't is that the eng samples are in this mode already.

Wow thanks a lot for the very thorough answer. Do you think we will see memory expansion as a possibility in the near future?

Ok, without trying to insult anyone, 'm gonna call Bullshxt. I now have 3 VP's in my possession. Ok....1 I dropped and it doesn't start any more. But that still leaves 2. On both of them I have removed the SD card, replaced hte card with bigger and smaller SD cards and have even left the SD card slot empty. I have NEVER bricked my phone.
Let's leave performance behind first...and not consider it. Lets just talk about changing cards.
The key to changing cards is process. Take the card out and restart your device, it won't boot. there is no external keys for hard reset. Place that same card back in your device, it will start.
To change out a card, do this:
1. Hard reset your device
2. On the reboot portion, remove the battery and then remove the card
3. Put the battery back in and let the device start up
4. Walk through startup and your phone is ready to use.
Keep this same process each time. You cannot remove a card, without first going through the hard reset process. You cannot add a card with out first going through the hard reset process. The hard reset process initializes the card to the device.
I've done this at least a dozen times, with cards ranging from 2,4, 8 and 16g. I've done it with cards pulled out of Google phones and an HD2. I've done it with cards that have never been used before. Its 1, 2, 3, 4. No matter what combination of removal and add....1,2, 3, 4. Remove a card, its 1,2 ,3, 4. Add a card, 1,2,3,4. Simple.
Now...if you want to talk about Performance....thats another conversation....
Again....no insult intended with the BS call.

Sorry...forgot to add 1 thing.....this has been described on this forum several weeks ago...so...what I'm saying is not a huge discovery from me...but rather from the guy that posted this around christmas.....I just repeated it is all !!!

Oh OK, sweet thanks for the thorough step by step guide! This is exactly what I needed.
A few questions though.
On step 2. you mention a reboot portion. What does that mean? After hard resetting what is my "queue" to remomving my battery and SD Card
Also, you never state in the 4 step process when exactly I put my alternative SD Card in. Would I put it in step 3 when I put my battery in?
Finally, you say Performance is a different story. Are you saying that replacing SD Cards will make the phone slower or more prone to crashing or working less stably?
Thank you.

I think once the phone is ready to use again, you then start the process over again at Step 1, except instead of removing the SD card in Step 2, you put the new one in.
What I want to know is, if taking out the provided SD card voids the warranty, how do you get a new phone without paying for it? Or does the warranty not cover that specification?

none taken, but your claim about the device not booting if you remove the card is false.
It will boot, sans card, with ~15mb of free storage space with no customizations. It's also likely though that if your device does boot into this state, you will never be able to get another SD card to work in it ever again.
Even if it boots into the "no storage" state it's still possible to put in the old card (in most cases) and have it work. I'm just saying that has not been the case for everyone.

Looks like I've found quite a good amount of posts from people stating that they have swapped SD cards succcessfully so might try this if I feel like I require more storage. Would anyone happen to know if there are certain types of SD Cards I should use to make this work? Also, alodar1, you have stated something about performance being another story? Would I be sacrificing performance by swapping cards? What kinds of issues would I be having?

1) Open settings-> about menu in phone
2) Press "reset"
3) Press "yes" twice. The phone will start to reboot.
4) Wait until the phone shuts down and begins to reboot, and take the battery out. NOTE: If you take out the battery too early, it will not work correctly. I waited until I first saw the Dell logo pop up and then pulled the battery, and that worked.
5) Remove the old SD card (I used a very small eyeglass screwdriver to gently pry it out since it isn't spring loaded)
6) Put in new card, replace battery, restart phone
7) Go through the setup process
That should do it. My phone hasn't crashed since I replaced the card on Sunday, so its been a success for me. I have not had any performance issues with my new card - but I suppose that really depends on your card. Granted, I actually downgraded - I went to a Sandisk Class 4 8GB card. Soon enough I'll be getting a 32GB card and trying that one out.

Ah things are much clearer now thank you very much, will try this. I'll pray my phone doesn't go bad... gulp.
Also, are you saying you were a victim of the crashes and replacing the SD Card fixed it?

OK so I'm going to buy an SD Card, a 16gb, so should I go for a class 2 or class 4? What's the difference between the two and is any one of those two incompatible with the venue pro?

Yes - my phone crashed very frequently with the 16GB card. Many times a day. I've now gone a full week without a crash with the new card.

Mine is class 4. The problem here is that there is no official specification. The class rating refers to data transfer speed - but the requirement for Windows Phone 7 is random access speed, which the card manufacturers don't advertise. Early reports actually showed that higher class (6+ cards) actually perform worse in WP7.

I don't have the DVP yet. Will the warranty be void when the SD card is replaced/removed? Thanks.

Yes, the black tape shows "VOID" after you remove it. A prior warning would be nice, since the tape doesn't say that on the outside.

Does it really say "VOID"? I removed the tape but I can't discern any letters left on the device. However, I can see an "O" on the tape.

yep, it says VOID and the black VOID letters are left behind when you remove the sticker.

So for those who have replaced their cards, how is the phone holding up? Able to use wifi and the marketplace and IE with no crashes?

sorry for the delay in replying. No, not necessarily. Personally I believe there is an issue with the specific cards Dell used. But what do I know for sure. I swapped to another 16g card...nothing fancy...just directly out of the HD2.....it worked and performance was better. A couple of friends of mine did a similar swap, looking at specific R/W speeds, class types, etc. They had mixed results. So, my guess is, there is something else that is a trigger that no one has hit on yet. I know my 16g performance is not as good as the 8g performance....in smoothness of card access. If I swap down to an 8g card...or even a 4g card....I can see the difference.....the performance is smoother.
Now, this doesn't say that those people with the 32g cards are NOT seeing that smoothness. I'm saying that I tried this as a test because I had cards laying around....and noticed a difference. The difference strongly indicates the shipped 16g cards are not what they should be. But, this does not mean the 32g cards on the market right now are the answer.

HELP !!!
I tried changing my 8GB SD card to a 16GB SD card. it booted up fine everything seemed ok, but when I restart the phone it loses all settings. So I put the original card back in, followed the same steps. Now my phone only sees 16 MEGABYTES of storage, I've tried multiple factory resets, after a reset it doesnt even go through the normal setup process. All it does is go back to the homescreen with only the normal tiles accept all the newsroom, tmobile family room and stuff isn't there either. If I pin an app to the start screen then restart the phone the pinned app is gone from the start up screen can someone PLEASE help, I'd be happy just to get it back to normal, with the original SD card in it

help!...weird wp7 issues

Hello everyone ,flashed magldr 1.13 and a wp7 rom and my phone reboots and freezes along with when my phone goes into sleep mode and I press a key to wake it up,it usually doesn't respond or just reboots....any suggestions ?

Sounds like you're using an incompatible sd card... WP7 is very picky with what SD cards work with it. You need one with good random access speed (which has nothing to do with class... in fact higher class cards tend to have lower random access speeds).

Confirmation
I agree with you, the symptoms are exactly like what I used to have with my first attempts with WP7 using the originally supplied sdcard (T-Mobile HD2). Believe it or not, I exchanged my sdcard with my brother's (from his omnia1) which was the same make, size, and class; voila, no more problems.
Later on, I purchased an 8 GB class 4 and tried it with WP7 and the same problems returned... so, it REALLY is picky about sdcards.
I hope this helps - as a confirmation.

Good info guys,using the mobile 16gig that came with phone...also bought a 8gig class 4 sd card yesterday and still same problem ...gonna buy another 16gig class 2 when I get home later ....do I have to flash rom again when I change sd card?????

WP7 doesn't support swapping of SDcards, so its going to reset immediately anyhow! For the sake of thoroughness, turn your phone off, put in the new SD, goto magldr's USB Flasher mode, and flash the DFT WP7 ROM.
Enjoy
Note: check out the thread on compatible sdcards before buying your new one. Cheers

no you don't, follow the steps from this site
http://www.techienote.com/tag/technology
you will get your information back with the old system, but but!!! if you didn't get a stable wp7 i mean if you didn't use it for a good time more than 5 days.
it would be better to flash new wp7 on ur new SD card.

In simple terms you can't.
One of the reasons most WinPhone 7 manufactures hid there SD cards deep inside the units was because MS have some very specific requirements for the performance and specification of SD(HC) cards that the OS will use to combine with the on device NAND storage.
This mostly comes down to the speed of 4k block read/writes (so it seems) but also seems to require some card features that not all cards have (so there is some definite 'blacklisting/testing' going on during that 1st boot it would seem).
In simple terms, if after installing your SD card and doing a reset of the phone (via settings, about, reset or holding VolUp and VolDown during and after the 1234 GO GO... from Magldr) you don't see the SD card as usable space it is safe to say that it does not meet the requirements laid down in the WinPhone 7 SD driver and is not going to work, go and try another card .
If your card IS recognised but the device seems exceptionally 'laggy' (hanging on the installing apps screen for a long time after the 1st reset is a big clue) then the chances are your card is no where near quick enough in the 4k read/writes to be used correctly by the OS (even though it detects it), again, time to try another card.
There is anecdotal suggestions that removing all existing partitions and on the card before you install it in a WinPhone 7 device helps with it being detected but then even if that is the case those same cards seem to then exhibit the very poor performance as above and that tends to imply they got blacklisted for a good reason .

Where can I get this SD card blacklist for HD2 WP7?

Click to expand...

There isnt a blacklist as such
if any portion of your card doesnt match the required random access speeds then you can expect several outcomes
firstly it doesnt work
or you might get it working but with Wifi issues, lagging issues, unresponsive screen, random resets.
or you might find that only a portion of the card doesnt work, forinstance, mine was fine, then i slapped some music on it and it started this reset business, so i slapped some more music on it and it went away, take the second bunch of music off and it starts again, all portions of the card are in good working order but for whatever reason it didnt like using a small portion of the card for system uses.

Correct me if I'm wrong but it also sounds like he is installing WP7 and then inserting the SD card afterwards.
The SD card should be inserted before installing WP7, so it can partition the SD card correctly and see it as "Total Storage" because WP7 doesn't support removable storage to begin with.

I think your Sdcard does not match to Wp7.
Change another sdcard and try again
I am using Sandisk 8m that for your reference.

I have 2 cards thay are both sandisc one is 16 gb the other is 4 gb i think thay are both class2 but am unsure thare is a logo that says c2 in the top right of the cards
however I dont think thats what the probulm is!
but am unsure.
I realy hope someone will help me figure this out.

Are you having this problem with BOTH SD cards, or just one?
The SD card, WP7, HD2 combination is very finicky. My Kingston 8GB c2 seemed to be functioning perfectly fine, with the exception of 6-7 hours battery life w/ little to no usage. I also noticed that it took a while for apps to install at the last step of a hard reset on 7720.
Thinking that Kingston was good, I upgraded to 16GB c4. The device wouldn't even boot past the splash screen after leaving magldr. So, I changed to a PNY 16gb c4 and got to see just how badly my 8GB had been performing. The apps that took a while to install at the last step of hard resetting Mango were installed in an instant. And my battery life tripled. I don't have to worry about my phone dying anymore.
So, it's very likely that your SD card can be causing the random reboots. Use dev_storagelock to unlock the card you currently have installed. Perform a hard reset. Stop the process when magldr starts and swap cards. Allow the new card to be integrated into WP7 and see if the reboot problem persists.

It's probably not the ROM and most likely the SD card. That's what WP7 does. It's super picky.

i did a haed reset and cleard all crc data the problum still ocurs
the only diffrence to both of the sd cards a i have is size
so unless i was to go buy a higher class im gessing buying another would be pointless
the weard thang is this didnt alwase happen
i used bttfv1 no problums
had bttfv2 then all sorts of problums started happening first time i flashed most of the updates with zune
then was forced to start from scrach agin after i messed up my registry with advanced config
second time i upgraded to bttfv2 i used the one shot method and im not exactly sure but i think thats when i started haveing the issue.

You allready know what's wrong, it's the SD cards you've been using. Keep trying with class 2\4\6 Sandisk cards.

what was that a sarcastic remark? & no i dont know whats wrong because as i stated before i didnt have this problum before my previous installation.
i am useing sandisk class2 16gb i am useing the card that came with the phone i realy dont understand why that would be the issue?
whats the best card to get then?

Your SD card would be the issue if the card or some sectors on the card lacks the required random read\access speed. This could very well create problems on one installation while working seemingly fine on another.
I've already said what cards I believe gives you the highest chance of working, you'll just have to keep trying with those. Theoretically you could also try reinstalling the whole thing and hope that no critical files ends up on the lower speed sectors of the card, but I don't know what chance that would have of working.

The only marketable difference between the cards may be size, but WP7 doesn't really care about that. When I we say that it's picky, we really mean it. You can have great success with one card, and then put another in of the same brand different class and WP7 will no longer boot. SD cards affect battery life and everything.
By an SD card from Fry's, if there's one around. They've got a 15 day return policy w/o restock fee. I only went through 2 cards finding the right one to upgrade to, but was prepared to go through their entire selection and the sales girl even told me to not feel bad about doing it.

Hi,
probably you must calibrate battery or yours SD card not works correctly...

I had the same issue bu not due to Sd card
I have a Kingston 16GB calss2 works perfect
The issue was that the original rom was American English
if i istall like it is everything works good and since i/m greek i can use also the buld in greek keypad with no problem
BUT when i change to my language the full functions of the phone , then it keeps
restarting byitself ....
For me no problem to work with the english menu at all , so i keep the device in english and works.
