Hello People
My external screen it does work because when i turn on the phone I see it active and looks good. Once the OS is loaded the external screen doesn't work when I close the hinge and the phone does not lock automatically after folding it either. External screen work perfectly fine if i shoot camera (the smiley feature).
Do you think just as i do that this is a hardware issue?. If so, could you please point where the "inverter like" mechanism is? In case is software, what can i do keeping in mind i already own the newst rom version available.
In the patent the manufacturer talks about "flex sensors" but they said that is optional and they may include them or solve that in a different manner (something classic not involved in the patent)

Has anyone had any success fixing the hardware on these units? As I have mentioned elsewhere on these boards, I dropped mine and now two things have happened: Firstly having successfully upgraded the ROM/firmware to XDA, the touch screen has stopped working almost completely. Occasionally it does respond to the touch, and the bits which respond are uniform but aren't the bits where you have touched!
Secondly some vertical lines have started to appear to the extreme right 2-3mm of the screen, indicating that there is some type of chip at the edge of the screen??? (someone suggested the digitiser but when I tried to ask a question about this, no one seemed to know what or where a digitiser was) In addition, when I press on the casing at where the lines emanate, the lines get worse.
I took the back off and found that it does seem very difficult indeed to get at the screen to replace it. Secondly, there are some difficult-to-identify bits floating around inside it (they may be just retaining pieces for the lower left hand case screw which is missing)
As there has suddenly appeared a job lot of 100 of these (obsolete?) screens floating around New York I was wondering whether it was in practice possible to replace one or is the amount of work involved cost-prohibitive?
It would be kinda nice to get this unit operational again (especially now that I have successfully loaded your ROM and unlocked it) if this could be done at not too great a cost.
The digitiser is also known as the glasstop and it's the pressure sensitive cover over the top of the LCD - it is a seperate unit although attached firmly to the LCD it can be replaced.
Try www.ppctechs.com for a price? It's farly easy to remove the screen if you want to do it yourself - I've seen a few guides on the internet.

p.s how much / where was the job lot of screens?
china
They seem to be originating in China though I had a disastrous time getting hold of some. I got two. not sure if they are the sony originals but will try to install and report back if I can figure out how to get one in.
Where did you see the instructions on taking this thing apart?
Hi there,
as i wrote in the Rainbow Mod for Lumia 800 thread, i'll try to restore DLOAD, update to latest FW, and restore Qualcomm (all with ATF Testpoint) again, that i can give you updated files on Partition 3 of the phone, that the latest rainbow mod build will be working on all phones...
But it seemed that i had a pretty shaky hand, when i was soldering my device, that i "destroyed" a component.
First, it was still fitting, but a little "twistet" as you can see on the pictures attached.
I checked if the phone is still working, and it did, except the "light sensor" which turns off the display when making a call... I can now cancel the call with my ear accidently
I realised an extreme heat and battery consumption when making a call... but maybe it just seems so, because i'm looking for "mistakes" because of the broken component...
Then, because of this, i disassembled my phone again, to check the component... and i just touched it a little bit, and now it fell off...
The component i'm talking about is called "L1605" in the schematics plan, so it should be a "coil" (hope this is correct, as English isn't my native lang...)
Of course, because it "fell off", i don't know how it was placed before. Does a coil have a "polarity", i mean "+" or "-" ? or can i just solder it back onto the mainboard?
i hope you can help me
cheers
hi there,
i searched again and found out, that the "L1605" is an "27nH_0402". In the schematics plan it's part of the "reciever", as you can see in the image attached.
Can you tell me if this coil is important? It "just" goes to GND, so maybe it would be enough to just connect the to pins (were the coil was placed) with some solder ?
It also seems to be part of "FM & GND", so maybe it's just important for FM Radio? I don't use this anyway...
pls help!
i guess it has no polarity...but if u could upload a more detailed picture maybe i can see it clearly..
or search for ( as u can see the black component which has a white sign near the two condensator - it has polarity ) signs, i mean +, or a little colored circle on the component, or some cut-off and if it has one of these it has polarity.
what kind of paste did u use for the soldering? leadless or pb? it does matter.
ps : L means Inductor
It's a simple inductor. You can just solder it back in. It has no polarity.
Do not shorten the contacts. The circuit will probably behave bad.
hi there,
can you recommend me any "special" hardware?
With links would be great!
I only have an ordinary soldering-iron, whrere the tip is 3 times larger then the component
cheers
Here is some of the equipment I use for such a fix:
* Weller WES51 soldering station
* Weller ETU soldering iron fine tip
* curved fine tip tweezers
* straight tip dissection probe
* 20x stereo microscope
* solder
The WES51 soldering iron is available for under US $100 online (Amazon and elsewhere) with a variety of replacement tips available for about US $5 each, and I recommend it if you will be doing much soldering. Otherwise, you can probably find a cheaper one with a fine tip, but without temperature control. When soldering and desoldering small two contact components such as your broken inductor, the best method I've found is to use a second soldering iron so you can melt the solder on both the pads at the same time. Small components are hard to handle, so tweezers and a long sharp needle / dissection tip are very helpful. It's hard to see what you are doing at that scale, so a stereo microscope is almost mandatory. AmScope has some cheap microscopes that are adequate for this purpose, or you can find a fancier used one on eBay. My only complaints with the AmScope microscope I have is that the depth of field is somewhat shallow and I need to get my face closer to the work area than I would like. You can use and lead/tin alloy or lead-free solder designed for electronics use to do a fix like this. Lead / tin alloy solder melts at a lower temperature and is much easier to work with than lead-free solder but may not be as easily available in some countries.
I can't tell for sure without a bill of materials for the phone, but based on what you've said it seems like the replacement part is a 27 nH air core inductor 0402 size such as Murata LQW15AN27NJ00D, which is easily available through Digi-Key and possibly other online electronics component vendors.
I was on the train today in london, england and I happened to see that the man sitting next to me was holding a phone that for the life of me I have been unable to identify. I know of most popular phones and brands but this one has eluded me. The man was of an oriental persuasion and was in his 20's so this may be a phone from an eastern manufacturer that no one has heard of over hear as they are a lot of oriental students in this area?. The first thing that caught my eye was that the phone was running android N 7.0 (I assume one of the developer builds) However he was not on a nexus device. Bear in mind that on the day of this post Android N 7.0 has not yet been released?. If any one can help identify this phone then please reply as this has been bugging me ever since here are all of the phone details I was able to see.
- It had a full metal body
- 2.5D glass screen between 5.5"-5.7"
- Rear mounted circular fingerprint sensor
- Cameras in the top corner of back and front (so not in the middle like a samsung or LG phone more like iphones positioning for camera)
- USB type C port
- Dual speaker grills flanking the USB C port on the bottom which were not machined into the body (like on the HTC 10) but rather had slits cut out for them and they sat slightly recessed into the frame behind a mesh
- On screen navigation keys
- Stock android 7.0 N
- It seemed to have rather apparent chamfers on the metal housing of the phone similar to the HTC 10 (but this was not the HTC 10) and given the rumors of the HTC nexus (sailfish) coming soon I found this design choice interesting?
- The phone also had antena lines in a similar place to those on the nexus 6P but this phone did not have the black visor for the camera module that the 6P has.
- I could not see a logo on the back of the phone as it had a plain black case on it which makes me think that this is unlikely to be an unreleased phone if there are cases for it? unless this is covering a logo perhaps?
And a logo on the bottom of the screen under the glass (where capacitive buttons would be) That I have tried to replicate below as it was not made from the alphabet. (the logo was a lower case t a backwards capital C and a backwards S that was broken in two halves horizontally and was in a very square and srap corner font)
t]2
This was definitely not a nexus device at least none that I know of. It could be a nexus device that has not been released as I cannot find any other devices that run stock android 7.0 as of this date and have this design? however the logo on the bottom of the screen seems to imply otherwise.
Please let me know if you have any ideas of what this phone is. thanks,
Hi @All,
unfortunately there is no attachable keyboard cover for the S9 yet like there was/is for the S8. I know the camera and fingerprint scanner are different. But would it work (or did someone maybe know someone) who actually tried it and modified the keyboard cover so it works with the S9...
Kind regards

Would be interesting to know.
Remember that the cover-part has a (nfc?) chip and a magnet (near the power key). And also the keyboard part has a tiny magnet in the lower left.
I took one for the S6 Edge apart, and I can see that the S8 is quite similar. See this
So it is NOT just a matter of cutting a larger hole in the cover, the phablet has to be prepared for it with the suitable strategically placed magnetic sensors to detect that it is there.
For fun I have tried to use some of the non S8-variants on the S8, and could get an S8 back to react with the print part from the S6 Edge.
I also tried some of the other backs, but could not get them to work with the S8 (not even with the S8 keyboard)
But as it seems they have stopped production for Note 8 and S8, I think they unfortunately are abandoning the whole idea, so we should be damn lucky if the S9 got the correct sensors AND even in the same place as on S8
ADD:
Just had a look at the ifixit tear downs of the S8- and S9-, and it does not look promising for a total fit....
On the S8, the magnet at the back has its centre approximately 32mm from the top, and 10mm from the power-switch side.
So if I can measure correctly, the magnetic switch must be the tiny little component mounted north of the square chip with "C3 559 X791" (north of the orange square) here, but the S9 got no chip at that location AFAICS from this.
BUT the S9 does have a similar looking component closer to the vibrator, so it MIGHT be prepared for a cover...
The magnet on the key-part is about 16mm from the bottom and 13mm from the volume rocker side. Just north of the tip of the 3.5mm plug. And there IS a similar small component on the other side of the small print on both the S8- and S9-...
ADD II
Apart from the above add, note that surprisingly the keyboard with an S8 ALSO works both in Aeroplane mode and with NFC turned off, so the communication with the case must be a dedicated circuitry.
So that has to be there for the S9 too...
ADD: I just verified that the chip is on a small plate, and thus NOT with any antenna in the back plate (updated blog post linked above), so it SHOULD be possible to move that to another location, if the circuitry is placed elsewhere on the S9-
I just tried the s8 keyboard and I could put it on my s9 (snapdragon). It was a very tight and unstable fit, but when I did get it to click the phone recognized it and resized the screen accordingly. Unfortunately the keyboard below wasnt alugned with the buttons, and there was mostly no response. When it did respond I got a key registered from the row below and to the side, e.g. when pressing 't' it would sometimes register as 'f'. Any ideas on how to get this to work properly?

Very interesting that it works that much! Thanks for the info! This at the least proves that the a S9 was designed for a keyboard.
To bad about the slight misalignment though. Do you see the same displacement in all columns? I mean does a W also give an A, and a P an L? (when it does anything)
You COULD try to take the print out and see if a slight move would fix it. But there is no guarantee, as they could have changed the spacing in either direction too (perhaps squeezed in an extra column)
Why SamSung doesn't make for S9?

However, the Samsung Keyboard app, which is responsible for software support of the cover keyboard, does not have a separate kb-cover's layout for the S9 device. This app has layouts for S6, S7, S8, etc. Note 8 is the latest model supported.
Keyboard cover working in exactly the same way as the smart covers. The chip on the back of the case tells the phone the accessory ID, and the magnet on the front signals about the event - the keyboard is connected or the smart cover is closed.
This means that any Samsung smartphone that has version 3 of the Samsung Keyboard app (versions 4 and 5 no longer support cover keyboards) and can detect Samsung accessories, will work with cover keyboards, even those intended for older models. The only problem is shape of the case, I mean geometrical parameters.
1) You connect the keyboard
2) The phone recognize it via back chip + magnet
3) Samsung Keyboard app began to receive signals from it and process them
So no, most likely S9 was not designed for the separate keyboard, but this phone supports keyboard covers from older models.
I have several cover keyboards for S6, S7, S8. I'm thinking of adapting one of them for Note 8 (because it's impossible to find an official overlay keyboard for it!) or another Samsung phone, such as S9 + or Note 9, for which such an accessory was not released at all. Here is my plan:
1) Take a standard protective back cover, glue the chip from the old keyboard cover to it, cut two grooves to snap the front piece with keyboard into place.
2) (most difficult part for me) Design and 3D print a new front part of the keyboard case. Extract the keyboard module and magnet from the old keyboard cover, and fit it into the 3D printed front part.
3) Modify and rebuild the Samsung Keyboard APK to change the XML layout in order to match it the physical layout of the buttons. I may need to get root access to install a modified application, or I may not - IDK, need to try.
I think this should work. At least it looks like it should work.
Unfortunately, I don't have much time for this activity, so I don't know when I'll do it. But maybe it will help someone in his research. Good luck!
Posting this for reference, for folks who might have the same issue.
GPS mostly stopped working on my Xperia X Compact; would work intermittently only about 10% of the time. GPS tools confirmed no GPS reception. Various postings throughout the internet indicated this to generally be a hardware issue, and fixable only via Sony service.
In my case, it turned out the GPS antenna was simply not making contact with the GPS connector on the mainboard. Fix was relatively easy.
The GPS/Cellular/WiFi/BT antennas on this phone are all located on a removable "inner frame". These antennas all "connect" to the mainboard via "contact points". There are no actual "locking connectors" or anything like that. Just pressure between the contact point on the "inner frame" and the corresponding contact points on the main board. Over time, the connection between these contact points can degrade due to dirt, oxidation, belly button lint, pixie dust, whatever.
Fix is to remove back cover, remove 7 screws holding down "inner frame", pop out "inner frame", make sure contact points are all clean, reseat "inner frame", tighten screws. I'm leaving out some minor details here; just watch the youtube Xperia X Compact teardown video for specifics. Note you will need tape and/or glue to keep the back cover on after this procedure; if you use a case it probably isn't an issue.
See attachment. Contact points are circled in blue & red. I don't know which ones are actually for the GPS, vs cell/WiFi/BT.
