[Q] Any problems with the Magnets? - Shield Tablet Q&A, Help & Troubleshooting

I know the magnets on the device are pretty strong, I was able to stick my tablet to my stainless steel cooker hood using the magnets, so I could watch the Formula 1 qualifying whilst preparing food.
I am just a bit nervous about shoving it in a coat pocket next to my wallet, or in my bag with my laptop, for fear of wiping any of the magnetic media, eg. Credit card strips, Disk drives, SD cards.
Has anyone had a problem with accidentally wiping anything, or am I just being unduly nervous?
Cheers!

If your laptop is off, you don't have to worry, but if its on and in the same pocket and Credit Cards with a Magnetic strips are not covered, they will be damaged over time.
If you'll be on the safe side, get a Leather-cover for the Tablet. There is still a possibility of conflicts, but you're much safer.
Hope i helped you.

My SD card crapped out

The packaging fell apart. It's like the plastic case was made very poorly. This means the read only switch fell out and it doesn't want to go back in. My question is
1. Is there any way I can solder something onto the SD card chip, like jump a few pins and force it to be read/write all the time?
2. If not, is there any SD card that DOES NOT have a switch to lock the card in case the packaging fails and it falls out?
It sounds like a really lousy card. Usualy the chip will fail long before the plastic becomes damaged.
If I were you I would get a new card, and not risk loosing my data.
MMC cards come without the switch as a standard and so do miniSD cards which are usually sold whith an SD adapter.
Sorry, can't help you on the soldering part.
The card still works, although it is read only, and a bit tricky to insert/remove because the plastic is falling apart. The quality of the plastic is really bad, it's quite brittle. I believe that the adhesive that held together the 2 halves of the outside shell caused the failure.
Thanks for the reccomendation on the miniSD and MMC cards, I'll look into some of those.
Just as a FYI only, what brand of card did you have that fell apart?? I'd like to know so I can avoid it if/when I buy another one.

Can magnetic-closure cases harm devices?

I've heard that magnetic fields can influence the semiconductors' operations and electricity as a whole. What do you think, can cases with magnetic closures harm phones?
No, there is negligible if any effect on phones. If that was the case, why would RIM provide magnetic cases for their own devices? There is no magnetic media and all of the solid state components will be unharmed by normal magnetism.
They will not harm the phone, but as some of them contain quite powerful magnets, I would keep the phone well away from your credit cards when it's in its case. That's if you have to rely on the magnetic strip at ATM machines or point of sale terminals.
Magnetic fields does not affect the operation of your device. (Always referred to normal magnets not super strong ones capable to mechanically damage the components). At the other hand static electricity may affect the flash memory ("rom") of your device. I had this problem several years ago with my m515 Palm. I was storing it in my car, under the driver seat. I was lucky it hasn't permanently damaged.
About the static electricity - can a case with microfiber inner lining damage the phone, because the microfiber acumulates static electricity?
And watch out for gremlins and leprechauns and the boogey-man. Seriously, you are a little too paranoid. Phones are just like any other electronic device. Handle with care and keep away from liquids and don't drop it.
The probability that you will accumulate static electricity, and that you will discharge it into the phone, and that it will pass through the battery cover, jump the lining to the metal pieces, and then jump over the plastic inner shell to the internal electronics is EXTREMELY small. Besides if you have a cloth case it won't build up static electricity anyway unless you continuously pull it in and out of the case (like 20+ times per minute).
The potential for damage comes from handled exposed electronic parts while being ungrounded, and the only way you should experience that is if you open up the housing of your phone, which for you I would say you should not attempt since it is only for more experienced users.
i've never had any issues with magnetic cases. in fact, thats the only thing i use.

Nexus One Car Dock Suction Cup

My mount looses suction after about 3 minutes and everything falls 'glass first' toward the stick shift! It forces me to put my life and car at risk trying to catch this thing to save my precious phone. And yes, I know how to use the twist lock feature and the accompanying disk. Am I missing a step? I know a long time ago it was suggested to use petroleum jelly with suction cups, but I thought those days were past.
Any (good) suggestions on making this stick long enough for a decent drive?

Attach the suction cup directly to the windscreen glass instead of to the disc, which I assume you have stuck to the dash. Mine has not budged in the 2 months I have had it.
if the disk or the cup are even the slightest dirty, you will lose suction.
Did you use the cleaning pad that came with it and made super sure it was clean?
Also attach it with the pull off tab facing up.
Its usually humidity changes that effect its suction, so I would probably re-attach it each morning and afternoon.
Breath a bit of moisture onto it. Also get a cleaning wipe and make sure both surfaces are clean.

[SOLVED] microSD Won't Stay In [PART FOUND]

A sad day -- My microSD won't stay in the slot. It seems to "click" in, but there isn't enough to hold it and the spring ejects it. It seems to have been getting worse over the last few weeks, but I originally thought it was a specific microSD. Now it is all.
Is there a spring or something I can try to bend that will help it retain the card?
Not sure if some cardboard would work or not. I've never taken one down far enough to see how the mechanism works for the sd card slots, so not sure what holds it in or not.
Looks like a $10-15 part if you are willing to mail-order, $30-45 here locally near San Francisco.
Apparently it is a no-solder install.
I did get some very strange looks holding my microSD in with one hand with great intensity as I was restoring a backup!

OEM Samsung Galaxy S 4G SGH-T959V SIM Card and SD Card PCB Board - Replacement Part
I picked one off eBay for $15, claimed to be new
Good Stuff
I purchased the part through eBay seller cellfixrepairs. They shipped same day and it part was, as far as I could tell, new. It had masking film on the top and the needed adhesive on the rear. It arrived USPS within two days (shipped from Los Angeles area to San Francisco).
Total time for the repair was under an hour. A #00 Phillips screwdriver is essential, and something that you can use to pry the case away is recommended; plastic is nice. It was a little scary prying off the old board, but it did come off without bending anything else.
The ifixit teardown is very nice to have available.

A guitar pick works good to pry open the case if you don't have the plastic pry tool.

[Q] used an ice pack to cool my note pro 12.2 condensation on outside maybe inside..

I wish I read these forums before i attempted to put an ice pack under my tablet.
what i did was under my note pro 12.2 i wrapped an ice pack in 2 plastic bags and put it under my tablet, it immediately kept the temperature to only 21C i was really happy but i noticed on the back of the tablet (it has a faux leather back that might be porous) there was condensation building up where the ice pack rested (water vapour in the air drawn to that spot) i immediately wiped it off and then put the icepack back on the back of the tablet, again after couple mins there was condensation so i wiped it off.
only after speakign to a friend did i realise that might be a bad move because the water condensation could potentially go to the underside of where the tablet had the ice pack (which is more plastic i saw a video of my tablet being taken apart so i know what the insides look like)
what are the chances that water vapour has gotten inside into the important components? there's no vents the tablet is almost air tight bar the micro usb charging slot on the right and the 3.55mm headphone jack on the left, the micro sd card slot is sealed, those are the only entry points i imagine water vapour could get in.
i did this inside my bedroom, not sure how humid it is relatively it was cold today around 8C but with southerly wind so felt more like 13C.. is it possible for condensation to get inside the tablet given what i've described?
there's no breeze, im indoors however i did see condensation on the OUTSIDE where the ice pack rested so i just assumed the bit inside it behind the back cover also was cooled down and naturally air moisture woudl be drawn to it.. that leads to the question how much air moisture is inside the tablet in the first place and is there any viable way for it to enter via either the 3.55mm jack or the micro usb port 3.0 on the right?
you said that condensation goes down not up but is it possible i may have condensation inside the tablet? surely naturally if there is any it would go to the metal parts of the device inside IF there is any, as a precaution i put it in a box of rice but read that silica is better so got a few of those and some instant noodles which apparently is better than rice to get moisture out.
my thinking is if it's sealed up as in like most tablets are.. how is the moisture going to get out via the micro usb or 3.55mm jack ports? surely the silica and instant noodles dont have enough sucktion power to draw all the moisture that's inside a sealed tablet?? or maybe i'm underestimating the power of it.
surely people with iphones or ipads can relate, the device is completely sealed just a headphone jack and a charging port.. people have dunked theirs in water and put it in rice and voila it's fine.. howerver if it was sealed to begin with only a small amoutn of water realistically is going to get in via the charging port or the headphone jack right>? unless it's submersed.
what i cant figure out is if there is condensation inside for whatever reason.. how is it going to get out?? there's only a micro usb port and headphone jack .. which might indicate that not much woudl get in way of condensation in the first place? i dont really udnestand the physics of it but i know cold surfaces attract condensation.. that proved it by the outside of the tablet but what about the inside??
i put it in rice as a precaution adn i really dont want to take it apart as im still under my 28 day return thing (ideally i'd return it but the colour i want has been discontinued) so i cant guarantee if there's moisture inside.. but let's assume there is.. how is it going to get out? this isn't normal water in cracks and in a phone which i can open up take the battery out and dunk in rice so the rice can be close to the areas of water.. this is just water vapour which may be attached to the underside of the back cover.. so obviously it'll heat up again because the insides get hot and evaporate.. but how does it get out??
I used ice packs to cool old phones when using as hot spots and they lasted many years. I doubt much if any moisture is inside but you can pop the back off relatively easy with a pry tool(pick basically) if you want to check.
If you left it there for many hours I might be concerned. Now I use a usb fan designed to cool tablets or small laptops I picked up for under ten bucks.

There was definite moisture on the back of the tablet I wiped it of. Which makes me think that inside the cover there must be too however is that moisture from the hote air already inside the tablet that just exists? Or is it new air which is drawn to the cold surface, the question is if I'm inside my room with just the normal air surrounding me maybe humid slightly can it get in via the headphone jack or the micro usb port?
Remember basic physics moisture and water vapour is drawn to cold surfaces and if there was definite moisture on the outside of the tablet where the ice pack was surely the inside behind the cover will have some too, how much I do not know however I cannot ptry the back open as I'm still under warranty and it'll invalidate it so I can't check
If thee is much air actually inside the tablet that definitelytinto water vapour condensation and stuck to the surface temporarily however when it heats up again it'll evaporate back into the air I presume but first as a liquid. Then. Back as a gas floating in the air inside, I doubt there was much if inside.
My worry is simple physics would state that even if the air from otside didn't get into tthe device the air inside already contains some moisture, the ice pack on outside would make the condensation occur and thus go to the back of the inside back cove rand surrounding metal parts which are colder, when I remove the ice pack ats up turning that replaced condensation into liquid (on the back of the inside of the cover) which when heated up enough should go back into the air as normal assuming 100% transder, it seems that all the moisture inside the tablet that's floating inside the hot air will be drawn to the ice pack spot inswhere the battery is. The danger part is when u remove the pack and the condensation then then turns back into liquid that's when it can get into important parts and corrode I won't know this for at least a year without opening itplus it may rust. When it turns b ack into a gas and stays in the air inside the tablet is that sufficient for it not to do any damage or is the damage done already?
I have to assume that when the condensation turns into liquid before it then is reabsorbed by the gas in the air inside the tablet it'll have done some damage. I'm not really sure how. Long that will be.
Does anyone know physics better and able to give me a better understanding ould have occurred inside the tablet?
You basically have the answer right. As the device is used the heating and cooling of the components will expand and contract the air molecules inside the device causing air to be drawn in/out of it. This allows a relative equilibrium between inside and outside air in terms of humidity so that's how moist air is in there to begin with.

I don't seem to have a problem with the temperature. Mine has the Samsung cover on it, so there is an air gap between the back of the tablet and the table.
I've had the P900 since September and use it 4 to 5 hours a day. OK the temperature here in Bahrain / Saudi is not in the 40°C yet, but it doesn't feel hot to the touch with use.
