Back Cover Stain

So I bought a back case for my Galaxy Tab Plus, a leather book case.
I have been noticing a stain at the back cover. It looks like it was absorbed by the battery cover, I don't know how to remove it. Any help?

Any help?

Same thing here, tried wiping it off and didn't work. I opted to place a protector at the back to prevent it from getting worse. Will try to clean it up tho, looks ugly...

I wish someone has found the solution...
Do you think Samsung offers back cover replacement? Of course not free.

Some more information might help.
What does the stain look like? Does it cover the entire back of the tablet or just one spot? Is there an odor coming from the stain? Have you examined the case to see if there is any substance that might be transferring from the leather or lining, such as a dye?
Have you stopped using the case? What brand and model of case?
A picture of the tablet back and of the case would be helpful.

It looked like the stain was stick in the plastic. It's kinda black. I still have the plastic on the back, but the exposed part collected the stain. It's like dye transfer
The texture of the case where teh back cover is placed is smooth. It's like matte. I bought a generic case for p1000.

Lesson learned. Cheap and/or generic accessories designed for another model than the one you have should be avoided in the future. Chuck that case in the garbage and contact Samsung support to see if they can suggest anything that can be used to safely remove the stain without damaging the plastic surface of the tablet.
Good thing you kept the plastic shipping protector on there or it could have been worse. Good luck.

I eMailed Samsung, they told me that the replacement for the Back Cover is 2,512 Pesos (Labor included)... It is equivalent to almost 50$ -.-

Might be cheaper to just get a new case and keep the stain covered up.

The back of mine 7.0 plus is gray not easy to stain, does yours white? What case is the best for 7.0 plus without too expensive? Samsung case is a hard one, I don't like it.

If the back of your Tab is glossy white plastic, the stain actually can be removed without damaging the device. This happened on my OG Galaxy Tab which had a white plastic back. I used an isopropyl alcohol wipe and a bit of elbow grease, although a bit of rubbing alcohol on a cotton ball would do just as well. You'll have to rub a bit, and you'll probably go through a few cotton balls, but it worked for my tab.
A word of caution though. If the finish on your Tab is damaged, (if you have deep scratches or chips,) I wouldn't recommend using alcohol on it as it will do more harm than good. If the finish is in good condition, just stained, go for it with the rubbing alcohol. Good Luck.

the problem is similar to my problem...i am new and I can't post photos of my tab until 8 posts

I have the same problem. It came from the Leather Book Case and it's not getting worst actually. It's just there now. Tried toothpaste and a "cleaner" for tech stuffs and none works.
Here are a few pics.

Sorry the back isn't so clear, flash kinda reflects and it's dark in the place I took these pics. As you can see it follows the pattern of the case, which obviously states that it came from the case. If it was clearer, you would see that only the hole where the camera is placed is the "whiter" side of everything. Lol. Hope someone can help us. It's kind of expensive to change it.
Update: Used the Alcohol method mentioned above. Works well, but does not completely remove the problem.

OMG!! it is my cover and my problem!!
where did you buy the cover?

It's not the same actually. Yours has stitches while mine does not but more or less the same shape and size. Haha. You should try the Alcohol thing, it works great.

HOW TO: replace I727 screen

I didnt see any other threads showing how, just asking how. But i broke my screen monday and thought since I didnt see any I would make a How To.
I take no responsibility if you destroy your phone
I have no ties to this place it just happened to be somewhere in the US that i could buy a screen from in white. http://www.cellphone-repair-shop.com

This is how the screen comes and explains why they are $200 its half the phone
1 remove battery cover , battery, sim card, and sd card if you have one.
2 remove the 7 screws that have red arrows pointing at them, you might keep the order but they seemed to be all the same to me
3.use your finger nail and pick to pull housing apart at the volume rocker and slide down pushing in occasionally to help separate
4. remove all connectors and the 2 black screws with red arrows. also completely remove the little blue wire its the radio antenna wire you will have to reinsert later.
5. slowly and carefully remove the board
6. remove this board with the arrow pointing at it from the arrow side you can use your hands or a pry tool
7 remove the small screw from this board shown with the red arrow and remove the board, just becareful there is adhesive where the yellow arrow is pointing
8. remove the earphone/speaker with your fingers pulling from the earphone jack, it has some adhesive on the earphone jack
9 use a small flat head and pry up the metal part and this will remove it exposing the front camera and proximity sensor
10. use a small flat head screwdriver to carefully pry up the the proximity sensor where the red arrow is this has adhesive holding it down, if it doesnt come up with the adhesive you will want to remove you will have to reuse it
and there ya go. now all your have to do is take your new screen and reverse all the steps and everything should work just fine
also if you are really careful you can remove your IMEI sticker with a razor blade and hairdryer and transfer it to your new screen =)
thanks for looking
chris

Nice writeup. Sticky pls!

good job man, you've got the balls to try it out on such a new phone without many people posting feedback

Wonderful write up! If I was a admin I will definitely make it a sticky....

It is truly a painless process. Broke mine on Dec 12th, and just fixed it Wednesday. 7 minutes and it was done. The hardest part is actually getting the new screen. Most online stores stay back ordered. But I am so glad to have it back again.

200$ still seemes awefully expensive for that, i've never seen such a high price for a lcd/digitizer assembly. I guess i'll have to take extra care of it

Wow! You could teach this to Samsung techs!

thanks. yeah alot of the places i found that had them on ebay was in china and i didnt feel like waiting 3 weeks for something that may or may not be OEM. i came across that place via a google search and called them to make sure they had it in stock. as far as it being 200 its a little more then just digitizer and lcd its like half of the phone. i know i saw one post where someone was compairing it to the $10 3g/s iphone screens.
but i agree the tear down wasnt that hard by any means just takes some care removing the parts with adhesive .I just like helping people with something that i come across

I got mine for $169.99. Shortly after, they raised it to $199.99. It is due to the limited availibility of the part I would guess. Took forever for me to get one in.

Great, can you share from where you bought it... i want to buy white LCD Screen

Also be advised- Depending where you get it from, you may have less work to do. The one I got already had the USB connection/ charger board and the proximity sensor and front facing camera installed. I only had to add the main board and antenna assembly. Pretty cool, as I now have extras of those things. Never hurts to have spares!

Thanks for the high quality images. I replaced my broken screen last night...everything works great. The new screen I ordered from dealrepairs came unattached to the plastic front adding a step. I had to pry off the old broken glass and lcd piece by piece with a razor blade since it's glued in. Have to be careful at the bottom where the home button sensors are attached. The new screen had three pieces of plastic over the adhesive back including a small red piece that had to be removed before setting back into the plastic base.

As he said, that plastic base has to be peeled off the screen. Most screens come that way without the plastic bezel. So expect some fun guys.
Hairdryer helps loosen the double sided glue. It looks easy (and is) with a whole screen, when cracked though... OMG /wrist.
Be careful with a razor to peel the tape off the glass for the button sensors. The glass and the razor can damage the filament and/or the LED solder joint.

Most places I see on eBay show a picture like this:
What's up with that? Can we actually remove all this stuff? Or do the boards come like on the OP's picture?

My glass broke, but digitizer and lcd are fine. I just received the glass only from ebay yesterday. blkkouki, how hard do you think it would be to separate the glass from lcd and digitizer and glue the new glass to old lcd/digitizer? I know I will need a heat gun. Thanks.

Penny WiFi Fix for AT&T HTC One X PJ83100

I will start off by saying I had a picture. I know I took it with an old phone but when I started it up again a little bit ago it was not there. Don't know how I managed that. I have to open it again in a few days when my new power button shows up so I will take photos then and add them. For now you get the crappy paint diagram.
I Performed this on an AT&T HOX released back in May Model PJ83100.
This fix gained me FULL or near full WiFi signal in places I was getting ZERO signal before. I could not get WiFi at the back of my house on the inside, now I get connected in my back yard. I really thought this was going to be a waste of time but boy was I surprised at the signal strength after.
I TAKE NO RESPONSIBILITY IF YOU BREAK YOUR PHONE DOING THIS OR IF SOMETHING HAPPENS IN THE FUTURE. YOU ARE TAKING THE SAME RISK I AM IN TRYING THIS!
Basically I popped the phone open with a thin guitar pick run along both sides from bottom to top pretty much like every video shows. (DO NOT USE A HOOKED OBJECT, you will be sorry!!!)
On the inside of the back of the case on the left edge just below the usb port hole are two gold contacts. They are the pair closest to the edge of the left side. I saw the letters BT with some numbers before/after them printed on it.
Starting with the lower of the two contact points (farthest from USB hole):
I got out some tinfoil and used an exacto knife to cut a 2 - 3mm wide strip. At one end I made it the same width as the gold contact but twice as long and then folded it over on to itself over that wide section to make it twice as thick at the contact point and the same size as the contact. I took a 3 inch strip of some scotch tape and attached it to some clear plastic. In my case the address "window" on a piece of junk mail. I then used the exacto to cut the strip of tape in to thin strips about 6mm wide. I took the foil piece and laid the wide end over the contact point and let the thin 2-3mm "tail" run along the black cover over the real antenna towards the bottom of the phone. Basically from the contact point straight towards the bottom. I had to dry fit it and trim the thin part (the tail I mentioned earlier) to length so its just as long as the black material under it that covers the actual antenna. I then used a small strip of the tape I trimmed to completely cover thin part of the strip except for the wide part at on top at the contact point.
The Second contact Point (closest to the USB hole):
On this one I did something similar but instead of it being straight it was more ad upside-down "L" shape. The hook in the bottom of the L was the part I put over the contact point and again made it double thick and the same size as the contact point but a bit longer. I then cut the longer "leg" of the L at 2-3mm thickness same as the first piece of foil. There is a space between the BT/WiFi antenna's black insulating cover and a big black square covering nearer the middle of the phone that matches up with it being behind the battery and the NFC antenna just above that. It is the actual polycarbonate of the phone. In other words there are no antenna or anything else there its a white spot on my white phone. I laid the 2-3mm leg in that area directly against the back of the phone and used another thin strip of tape that I had cut similarly to above to cover it. This piece of tape I let run a little longer above and below but not over the part of foil on top of the contact point.
Finally I took a full width piece of tape and went across both foil legs up to the contact point of the first, smaller piece of foil. Again making sure to keep the contact point uncovered. Over the rest of the L shaped piece I used a smaller thin strip of tape above the wider piece to cover the rest of that one a second time.
Bottom line you DO NOT want either piece of foil touching the other and you DO NOT want any of the foil except the area on top of the contact points exposed where some part of the electronics of the phone could touch it and fry your phone. I used scotch tape if you want to, use electrical tape. I wanted something that would come off easily leaving behind little to no residue or doing damage coming off.
If you have done this correctly you should have something that looks like this:

Adding:
I have seen others talk about using foil or solder to fix this. I am not reposting someone else's idea. I haven't seen anyone do anything with foil other than cover the contact point area to make it thicker and reach the gold prongs on the board.
I'm also adding that there was no real science or theory behind this other than the foil would increase the antenna surface area and the double thick part at the contact point would make a better connection with the phone electronics.

Might try this if I replace the battery with the X+ one.
Sent from my One X using xda premium

Not sure what the inside of the X+ looks like.
I have seen many disassemble videos and only one actually looked like my phone on the inside.
I should add that my Bluetooth worked but was awfully short range when compared to an other phone I have owned. With this change Bluetooth was connecting and staying connected much farther away. Can't say if the quality was good when connected, just noted it was connecting where it wouldn't.

Photo added now. If you note the foil on the upper contact point shifted. I repositioned it closer to the area the prong contacts the back before re-installing. Didn't hurt or help wifi reception anymore than it already has.
I will also add that the power button ribbon cable with attached upper mic replacement was a bit harry. In the videos you can see online it is obvious that the people shooting them don't give a crap about the prongs on the board or putting it back together. They just blow through ripping it apart. When you are worried about it actually working when done you are much more cautious/nervous!
Also, tip for anyone who cares. The screens power comes from two contacts at the top of the board that touch prongs on the top, back of the screen. If you try to turn it on (like I did for testing) and don't get a picture and you didn't screw it down that is why!

SmartWatch 2 - Inside (PHOTOS)

Have you ever wondered what's inside your SmartWatch 2 ? No need to google, you won't find. Here is what's inside. After a day from swiming pool some water got inside, no idea how , so I opened it to dry it because I couldn't turn it on. Now rests in dry rice, I will come back with and update if I could make it work again, also I need to find a way to glue the screen to the bottom / motherboard part ( 1st pic ) to make it waterproof again. I will keep you guys posted.

I had one break from diving in the ocean. The USB port is not a very good seal. Things like chlorine change the surface tension of water and may allow it to penetrate more than tap water.
I'm gonna be opening mine soon too. (I made a QI charging mod) but I want to see if I can put a coil on the inside, instead of the outside.

Well, that can be true, the port doesn't supports the pressure more than 1 meter.
Now seems it is working again! I glued the screen with a black silicone, looks like new.

While I don't think swimming with the watch was the best idea... I am truly impressed by your repairs and getting the watch to work again. Congrats, and thanks for posting the pictures!

Yup that was not a good idea, it's good to take a shower it it, not for swimming at all. Yeah, thank you, that was a challenge to open it and dry it. First I tought I completely lost it ... but seems it wasn't like that.

So, the screen is glued to the front glass I'm figuring. I broke mine and I'm guessing I need to replace the whole screen.

Yup, you are right, the front glass is glued to the screen / display. The only way will be to completely replace the front part (front glass and screen). Contact SONY Service and ask for a screen replacement, they will help you as long as you won't find replacement parts on eBay ... .
It would be great if you will keep us posted to see how you fix it.

I fixed it, purchased the LG G Watch
Perhaps at a future point in time I will find a cheap screen, cause at the current price of the watch it will cost me almost the same to repair it here in Romania (plus the time and frustration as the Sony service is out of town).

Just dropped it of the table (1.2m height) onto ceramic tiles, impact was on the side, picked it up and said "wow, it didn't break". 30 seconds later first cracks started to appear. 2 min later it looked like that.

Badly swollen Galaxy battery - safe to handle?

I've recently found my old Galaxy S6 in a drawer, where it's been sitting for the last ~1.5 years. In that time, the battery has swollen very badly, pictures below:

I need to so something about the phone, I think it might be a fire hazard to keep this at home especially when I'm not present during the day.
Obviously I'm not going to attempt to charge the battery or turn the phone on in this state.
I'd like to try and remove the battery and take it to a recycling/ewaste collection point. I'd make sure to take precautions when removing the battery to avoid puncturing it or applying pressure, but with this level of swelling, is just handling the phone/battery dangerous? If so, I could instead take it to a technician to remove the battery or just recycle the entire phone - but I'd still need to carry the phone there, obviously, so some risk would remain.
Is there a risk of a sudden explosion or fire without warning?

Absolutely there is. Being an avid RC modeler for many years I have seen first hand what LiPo / Lithium ion batteries can do in that state. Not to panic you or anything, but just be extra careful when you remove it, and don't puncture the shielding wrap. Once you get it out, then I do as this YT video suggests to discharge and disable what capacity the battery has left.
Best of luck my friend, and just be careful.

Yep, my plan is to unscrew the board cover and hope I can simply lift the battery out, it's probably unglued itself by bulging outwards so much. I just wanted to know if I have to worry about it exploding just from being disturbed, and with enough force to deprive me of a few fingers.

It's actually funny that you say that. However, this is not from a LiPo battery, but rather an error that occurred in 1975
As long as you don't forcefully puncture the battery, you should be fine.
Spoiler: OUCH!!

If there's no charge on it, it's no big deal ie no stored energy. They got a fruity smelling solvent in them, not particularly toxicity. I've taken them apart before, they are quit flimsy. Read up on it.
If you're keeping the phone use small amounts of anhydrous isopropyl to soften the double sided adhesive fastening strips. The biggest danger is damaging the display, take your time.
It will eventually pry out, pinhole puncture the bag on the top if it helps. You can then bend the hell out of it if fully discharged and if this helps in removal. The display is what you need to be worried about.
The plastic containment bag is fairly thick, if does leak soak it up with tissue paper, keep it out of the phone. Keep any fluid anyway from contacts and the mobo.
Wash hands afterwards.
It may have already damaged the display by the pressure of the swelling.

Mission success - the battery is out of the phone and all my fingers are still attached. The screen looks fine, seems like the battery bulged it outwards and the adhesive gave before the screen could crack - but I'll see when I connect the new battery.
For anyone else with this problem, I just followed the normal battery replacement guides, but without heating the phone, and I was very careful to not crush or puncture the battery. To remove it, use (liberal amounts of) isopropyl alcohol to weaken its adhesive, then a credit card to very carefully and slowly try to cut through the adhesive.
Thanks for your help, guys.

Yay!
Dissect the old battery, it's interesting... and flimsy. If you throw it in a fire, not much happens... yeah, I recycle
Word of warning with using isopropyl alcohol... NEVER get it or other solvents near a LCD display as it will poison it and destroy it. LCDs are vented to the atmosphere on the sides and are not completely sealed.
On AMOLED phones anhydrous isopropyl can also be used as a drying agent for water contamination.
Use your best judgment as if it gets in between the display and glass it will leave a residue marks. Use at least 96% pure isopropyl, never use methanol alcohol, other solvents or rubbing alcohol (too much water).
Allow assemblies to dry completely after use.

The battery is fine to handle so long as you don't puncture it. It's full of toxic gas. The metals are long dissolved so there's no chance it holds a charge for more than a few seconds.
