XDA 2i touchscreen

I bought a replacement digitizer off ebay and they have sent me the generation 1 version.
Before I go and buy the right one can anyone tell me how easy it is to solder the correct one and also if anyone needs a generation 1 version I have a new one here and would be happy to sell it on.
Thanks

its a ***** to do, i just replaced one on my dads xda2, but its the same as the xda2i
after taking a long time to carfuly remove the original without damaging the lcd, i used a safty blade and slid it between the buggered digitizer ad its plastic mount, be VERY carful as u need to apply force and its easy to slip, as i first did and sliced a 2" gash into my thumb... not good. second time i was alot more carful. by putting the screen edge down on a table top and wiggling the blade down all 4 sides, be carful not to cut the lcd ribbon!
i had to cut the 2 side tabs on the touch screens ribbon down by 3-4mm and then seperate all 4 leads, this is due to the design of the gen 2 screen i just followed the way it was originaly soldered on.
you also have to have a low wattage or cool soldering iron, around 10-15watt as it is very easy to damage the contacts i heated the solder on the lcd side and pressed the digitizers ribbon onto it with a small amount of flux, then used a flat screwdriver to quickly cool it down the area, you also have to put slips of paper between the 2 sides leads and the center 2, as it will short out, this was also done originaly.
sounds hard to do but its easy with a little patience, and soldering skills.
i bought it from ebay as well
p.s. do not glue the new digitizer with superglue as you will damage the screen, i just placed it back in the case without sticking it in, been fine for the last few weeks but a few VERY thing strips of double sided tape will do or if your lucky some of the origial sticky stuff will be left over.

does this "digitiser" thing is the faulty part which causing the PDA screen to have so-called Dead area ?
or "missing area"
because I won O2 XDA IIi which can't create straight line at the bottom of the screen.
where and is there any tutorial on how to replace such thing ?
Cheers.

(GUIDE) How to change backcover on Galaxy Tab.

OK. So I bought this Galaxy Tab on a Swedish eBay site. Used.
And I got it for a steal really, but it was because it had a pretty scratched back side. Not a single scratch on the glass thou thanks to a screenprotector.
But I was browsing thru eBay and found my solution.
http://www.ebay.com/itm/11072469800...NX:IT&_trksid=p3984.m1439.l2649#ht_2185wt_922
Today it arrived and I had a pretty fun time replacing it.
So I thought that I would provide a little guide as to how to replace the backcover.
I'm not going to lie, it was pretty hard to crack the damn tab open. And other problems arose too but more of that after the show.
So. First of. You do this on your own. By following this guide you are doing it by yourself. What im trying to say is that:
I TAKE NO RESPONSIBILITY IF YOU BREAK ANYTHING!! PERIOD!!
Tools needed:
Case opener tool x3 or 4 (they are usually blue, and you need about 3 or 4 of them, why? Because the tab is HARD!)
Sucktion cup (Makes grabbing the screen easier)
A tweezer with pointy tip.
Triwing or y screwdriver (if by any chance u don't have one, no sweat, if u have a Philips 00 cross screwdriver you can grind away one of the wings of it with like a nailfile or 4. So if it looks like + grind one of the arms of so it looks like this -| get it? It worked for me. Cheap as I am ;p )
So lets get started!
Watch YouTube video here www.youtube.com/watch?v=urGUKerJOhg one or two times to understand the opening process. If you think you have the hang of it, jump to step 5. You only need to open it. Nothing more.
Step 1: take out the micro SD card and sim card (if u have one)
Step 2: locate the 2 screws mounted on each side of the charger slot. They hare hidden under the 2 round black dots that are on each side of the charger slot. Use the tweezer to remove them. They have an adhesive on so save them for repositioning later.
Step 3: Use the triwing or y screwdriver to unscrew the 2 screws. These are the only ones you will unscrew at all. So far easy.
Step 4: Now here is the hard part. The tab is actually pretty hard to get in to. You will have to use the case opener tool and push it between the glass and plastic covering that goes around the phone. And at the same time use the suction cup to pull the screen upward while prying the corners open carfully with the case opener tool.
Now its open happy feeling. While your at it you can see the batterie and check if its from china or Taiwan. If its china, you should get a Taiwan one as the china galaxy tab batteries had a batch that was bad and had some issues with battery reporting either to high or to low percentage. Mentioned in this thread:
http://forum.xda-developers.com/showthread.php?t=986067
Step 5: You have to remove the frame attatched to the backcover. Its easily done with care with a case opener tool. It has some adhesive but not much under so u can easily be a bit brutal to it. Besides, the backcover is the thing you want to change.
Step 6: Now that you have removed the frame you see that the new backcover doesn't have that fancy metallic covering inside, or the camera lens and led plastic. So first remove the camera lens from your old backcover to the new one, it has some adhesive on it but no hard one. Easy to remove. To the same with the led plastic.
Step 7: Now remove all the strips and other glued materials from the old cover and transfer them to the new. When that is done, press the black frame over the new cover.
BE OBSERVANT AND CAREFULL WHEN DOING THIS!!
or else you will break some of the plastic hooks that keeps the cover mounted on the frame.
Once the plastic frame and the new backcover is assembled and you feel that it looks damn good its just to close it up again... oh and put those two round black dots back over the screws when you are done.
Easy done
I must say that mine looks like a completely new tab! My wife thought I bought a new tab
Thanks for reading and if you found this usefully don't hesitate to press the "Thanks" button.
Over and out!

good post. but i will not be trying to open mine.
but thanks for the instructions. i am pretty sure i will come in handy for the future.
cheers!!!

Yeah. Maybe I should ad that putting some degree of glue on the new case and frame would be good.
Cuz now I can open my tab by just pulling the case off ... Wich is good I guess if you want to get in there for a reason. Switching batteries?
| MIUI Powered Galaxy Tab | Tapatalk |

How did you find the quality of the replacement?

Same as original. Only difference is that it doesn't have some metallic coating that the original has. But with it gone i actually got better reception!
Other difference is that obviously it doesn't have the imei number or serial number (duuuuhh) printed on it
Still strongly recommended!
| MIUI Powered Galaxy Tab | Tapatalk |

interesting, mine has some scuffs too, and doesn't seem that hard on the process

It is a easy process and its a cheap way to make the phone look completely new

Galaxy Note II Case with Stand Photo Review

Hi initial photo review of this case. Will write a full review later tonight.
In a nutshell it is well made and light. Fits very well in trouser pocket. Does not feel bulky.
Price about £10.
You will find them on ebay in various colours.
If these photos help you decide. Feel free to hit the old Thanks button.
Glad to be of service.

That case looks great. I love how it protects the edged of the phone, unlike the official Samsung flip case. Does the flap stay closed using magnets?

Yes it does. I will write a detailed review sometime today. Central heating pump failed and looking after a newborn has kept us busy. Lol

Thanks for the pics. A link or two to the ebay sellers would be nice, though...
Edit: Is this the same seller?
Also, does the magnet cause any issues with the s-pen?

Tried one out and found that I had to take the back cover off to fit the phone snugly.
Since the cover doesn't have an NFC chip, you will lose that functionality. The case doesn't fit on the phone with the back cover on unless the one I saw was a duplicate. Moreover the magnetic closure is flimsy too.
Just my 2 cents.

The NFC antenna is embedded in the Note 2's back cover.

For the record. The handset clicked into case. Nothing had to be removed. Grips it fine. Must be a different case if you have to remove covers.
So far only really annoying thing is using it one handed. The folding cover is in the way of fingers.
There is a similar case that has a rotating cover. That would resolve this issue. Also enables a portrait stand.
Also as suspected. The home button is being pressed by the cover due to no recess (think thats the correct word) in the cover. This is activating the voice assistant. Disabled it as it is rubbish. But will mod cover at later date.

Another little update, these stand cases are really good for watching iplayer etc. But I think I am going to buy a leather sleeve/pouch type case. Ive always used them with htc handsets, due to most usage is one handed. And save the stand case for movie time.

I bought the Original Samsung Note 2 flip case instead. Although it was expensive £30 .... but I think it looks really nice and still have NFC function.

The biggest flaw with the original Note 2 flip case is that the corners/edges are completely unprotected. If you drop the Note 2 and it lands on the corner it might shatter the whole screen.
Not enough protection for my taste...

I bought this case yesterday in a shop and was massively disappointed. If you fold the cover behind the phone to use it the phone is hard to handle and doesn't sit ergonomically in your hand.
BUT BIGGEST FLAW: The little magnet on the right side interferes with the wacom digitizer. Try pulling out the S Pen and draw a straight line along the right edge, and the line curves outward around the magnet.
I was about to return the phone when I realized the error was next to the magnet. Pulled it out of the case and problem gone. I could reproduce this problem anywhere on the screen by holding the magnet part next to it.
There are tons of reports if you google "wacom magnet s pen" about interference, so I would avoid using this case. There is apparently even a note about this in the manual somewhere.

This happens because wacom digitizers use magnets to work (partially, there's more to it) - the pen is a magnet. Crash course: A magnet creates a magnetic field around it. Whenever you're moving the pen, you're moving this field - any given point in space near the magnet experiences a change in this magnetic field (this creates an electric potential and a potential difference between points affected by the field). A really cool thing about moving magnets near wires is we create what's called an induced EMF - the change in magnetic fields causes electrons to move because of changes in relative potential difference between nearby points.
A static magnet (in relation to a point) will have a static field, but a field none the less - the magnet on the casing. When you bring two magnetic fields together, they interact to form a resultant field at any point in time.
The pen is still working as intended, but the other magnet has changed the potential you produce near that magnet via movements of the pen - thus, different and incorrect readings. It's relative to the position of the case magnet, so you get a different effect at different distances from the magnetic source.
The result is that the same motions of the pen near that magnet are causing different currents to be read than the wacom digitizer expects for that motion.
While it's great to hear through some empirical data that physics still works, I was already actively avoiding this case for this reason.
In contrast, previous smartphone cases with phones that use capacitive touch don't have as much an issue because it's basically a field of current that your touch (finger, capacitive stylus, etc) redirects some of that flow across. While a magnet could indeed affect this field, the magnet isn't moving so it's not as much an issue (it's still an issue because, depending on field strength, orientation, and relative locations, the electrons are still moving with respect to the magnet, and are repelled/attracted by the field in this manner to different degrees. However, the difference is constant and like is accounted for because digitizer system can't guarantee constant currents necessarily, so there is variation allowed for. With the Wacom pen magnet, it's weak enough to be noticeable.
TL;DR - Anyone with a course in EMF and an understanding of induction would be able to tell you this right off once they found out the pen uses a magnet. Incidentally, the magnet is also why you can do the hovering stuff so accurately. Other forms of non-touch gestures have many ways they could work too, but one way is your body affecting a field around the digitizer enough (whole hand swipe across without touching) that is is measurable.
It's also how inductive chargers (ones where you don't plug in the device) work. Changes in current flowing through wires creates a magnetic filed which, by orientating the wires, using loop/solenoid type configurations, this field changes (an AC signal). When your device is in the field, a similar configuration in the device is subjected to this changing field, and, more simply put, energy is exchanged via magnetic fields.
This is really cool because you've taken a changing current, which creates an electromagnetic field across other wires, which causes a flow of current.
Anyways, yeah avoid having magnets near devices depending upon EMF induction to work

In response. Regarding the case and holding it. I agree, does my head in sometimes. Hence why i may get a sleeve instead for when at work and use it one handedly most of the time. Regarding nfc, i aint convinced it would be affected until i get to test it. Regarding magnet, never noticed it until tested. Only effects 5mm of right side of screen and 15mm vertically, not the end of the world.
Just tested a piece of tin foil placed between handset and case at the point of the magnet. Didn't make any difference. Shame it cant be shielded.
Gotta say. The mobli is very well protected and the white case and mobile has yet to look dirty. Day job, hands get mucky.
Anyone got the case that the stand rotates? Does it make holding it less annoying?

So, can the magnet cause any permanent damage to the gyroscope, compass and wacom bundle? I did notice that the compass is off by 10 degrees with the case on versus off.
I've used the phone for a few days without the case and it gets greasy too fast. So its back into the case again. It is pretty sturdy, just wonder if its possible to extract the magnet somehow! Maybe lodge a knife in there or something.

Anything that works by sensing the Earth's magnetic field, such as a compass, will be screwed up by a magnet in a case. It's really not worth buying a case that has a magnetic clasp...

I lodged a kitchen knife in between the magnet and the case and jerked around. It broke up into several pieces and came out attached to the knife. Since its either in my pocket or on a table the flap stays closed and no more magnetic issues.

On the SIII, the NFC -ANTENNA- is in the battery... The chip is on the phone motherboard. In the Note II, the antenna is in the back cover. Are you blind? Have you never taken your back cover off?

don't be so harsh.
some of us ex galaxy nexus owners had NFC built-in batteries..

Stuck with a Rhinoshield

Hi guys,
I have been gifted a Rhinoshield bumper case this Xmas..
But I'm facing a problem now : HOW TO REMOVE THIS THING ^^?
It's hard to put on, hard to remove and a bit too loose on th side..
Envoyé de mon ONEPLUS A3003 en utilisant Tapatalk

I have one too. Too take it off i simply apply pressure to the top right corner upwards so that the phone comes out face first. After that its downhill.

I have one too. For me it seems to really depend on temperature. If you warm up the rubber part on the front, it will become softer. Apply pressure to the back of the phone on either of the top corners and the phone should come out easily after one of the corners are out.

Which tempered glass goes well with rhino shield bumper?

OK, after hurting my fingers and popping my screen half way out i found a solution. Okay the screen doesnt came off but I did can pop it back in a little bit.
I used a hairdryer and heated the bumber up a lot!
After it I did take it off!

Same thing here, this bumper really is too tight in my opinion.
I also heard several cracking noises when I tried to take it off, I did it exactly like they show it in their video tutorials...

i see the problem when people having a difficult to open this case is they are using thier fingers.
i just use towel or any cloth to cover up top right corner, then apply a little by little pressure by the bottom of your hand (not fingers). i use the skin around palm.
it will just flap opened. no heat or anything else. needed
And for those who terrified the screen will break, it will not.

Lol I did Not try this Out. Maybe next time
**** grammar correction (german) try to write words in caps

I want to couple my rhinoshield with either of these two:
1. Gadgetshieldz screen protector with front and back covered
2. Gadgetshieldz screen protector on front and a dbrands on back.
http://www.gadgetshieldz.com/oneplus-3-screen-protectors-covers-cases.html in case gadgetshieldz is a new name to you
Also I haven't still bought the rhinoshield bumper but my planning to do so and I want to fully cover my phone so has to prevent it from further debts or scratches

so far the best method to take off the RhinoShield! Thanks

Broken front glass (& usb port) - replacement?

Hi guys,
has anyone of you tried changing the front glass without digitizer and display?
In disassembly videos I can only see people changing the whole thing.
Also, do you think I can manage to repair the front glas as well as the USB port with just an iron instead of a hot air blower (and the usual tools made of plastic)?
Thanks in advance!

I haven't done the front glass on mine yet, but my understanding is that in general you're really better off replacing front glass as an entire unit with digitizer and display. An iron on pretty low through a cloth/towel might well work. It's not just glue that melts, it's a thin strip of rubber gasket material with adhesive (okay, maybe it's thick glue, but it looked pre-formed to me) holding the glass back cover on.
Heating probably helps a bit with softening the stuff, but after the first time you peel it up you won't really need to do that again. I'd recommend picking a corner (say, bottom left as you're looking at the back) and just plan on prying from there every time, so you only have one spot where the plastic gets marred.
Don't spend too much time heating, worry more about having a suction cup tool that you can lift with while you try to work a guitar pick or hobby knife or something in under the corner. Have at least two ready, so you can wedge one in, and work your way around without it just dropping back down on you. You'll probably tear the material a bit but that's okay, just spread it back out evenly around the edge on the glass before you put the cover back on. Also, you definitely should be using a case to make sure it doesn't just fall off in your pocket once you've opened it up a couple times.
USB cable replacement isn't awful, just time consuming. The biggest gotcha is to keep all three of the little gold clips on the plastic "mid frame" ring (that's the first thing you remove that requires screws after getting the back glass up) from fallling and getting lost.
You can PM me if you have any questions about this, I've replaced my USB cable/port assembly a couple times (first replacement was defective). And I'm about to attempt replacing the screen as a whole unit with glass & digitizer on my wife's Z2 Plus, so I'll let you know how that goes.
