S7 Homebutton/Fingerprint sensor issue - Samsung Galaxy S7 Questions and Answers

Hi Guys,
Recently i dropped my phone which caused some cracks in the top layer of glass ( pfew!:fingers-crossed
Offcourse i wanted to keep my phone in a decent state so i decided to look for a replacement screen which i found fortunately for a very sharp price including the frame, battery etc.
So; first things first, the screen came in - everything looked nice but it was clearly refurbished as i could see but lets be reasonable ; < 100€ for a refurb screen with frame, battery and homebutton isnt much right?
Ok, so i mounted all without any issue, yes i'm experienced, and the phone started up without any hassle :victory::victory:
But then i found out the fingerprint wasnt working....
I checked cabling, cleared cache, reinstalled my Rom - no avail ... :crying:
Supplier told me that probably i had to replace the original one and reset but i'm not buying it..
I removed the old one from my old screen and it works flawlessly...
With the installed homebutton i keep getting the error message that fingerprint isnt working, i should reset etc..
Is there anything i could try or would fix this WITHOUT putting back the original homebutton and risking to damage my lcd?
Thanks in advance :fingers-crossed:
S7 Exynos
Superman Rom 1.4.0

Sounds like the replacement might have come from a demo unit S7 which does not have a fingerprint sensor in the home button

Cracked Screen on my Touch Pro

I dropped my touch pro and cracked the screen in a few places. I think it works normally except for the screen, as it receives calls fine...
A new phone isn't in my budget right now. Does anyone know of a good place (hopefully in DC, MD or VA) that will supply or install a replacement touch screen?
(btw, no recent threads came up when I searched.)
Ebay!
Just looked, $30 including postage for a screen & digitiser if you are able to do it yourself.
How hard is it to replace a screen if it has surface damage? Is there anywhere i could find a walkthrough or help?
Shame man, its a tragedy of what happened to your phone...
Luckily its not too bad, and you may just be able to fix it. You can download the service manual for the phone here: http://htcwinmobile.blogspot.com/2009/03/htc-raphaeltouch-pro-service-manual.html
Just a note though, make sure you DO USE tweezers or something to get the speaker wires out of the way before snapping the enclosure back into position... I had to reopen the phone again, after powering it, to rejoin one of the little wires thats like a tenth of a millimeter thick DO NOT IGNORE ANYTHING THEY TELL YOU IN THE MANUAL. Oh, and what works well for the "plastic removal tool" is a cut out piece of plastic ice cream container. AGIAN, do not ignore anything in there... You are voiding the warranty permanently when you do it yourself (which you unfortunately have to).
Anyways, good luck!
I drop my phone also, but the screen didn't actually cracked! but I do have is problems with the screen in other ways! Sometimes I get a black screen when I turn on the phone and sometimes not, but when the screen turns on, it flickers a lot and have lines thru it. What suprises me is that sometimes I get perfect images on the screen (Which makes me think that the screen it's not damaged).
Any suggestion would be apreciated. Thanks!
3 days and still no answer from anyone! I would like someone to throw me ligth on this issue. I'm waiting for this to know exactly what I need to buy, before I start assuming things.
Thanks in advance!

Sounds like the LCD connector may have come unseated. You could open up the phone and make sure all connectors are firmly seated if you feel confident in your abilities.

Thanks for the advice! I was thinking on that also and wanted to take my chances opening the phone (oh god!).
BTW, I saw the $30 LCD Screen+Digitizer combo on ebay that Beeble referred to, but I'm not sure if it fits on the fuze (my model). What have come to my mind it's to buy also the front camera of the phone (like a thread on the kaiser) to mod the cell, in case I need to buy the screen+digitizer. I've search all threads about this issue but nobody has done it because it was too expensive for the result; I believe with this price it's worth it right now!
solved

I used Diamod (!) LCD and Touch Pro digitiser. Works perfect.
Much more cheaper
If your screen works fine sometimes, you most likely don't need to replace it. there's probably just a loose connection somewhere. If you really want to replace it though, there's an ebay seller with a really good deal. $20 for the screen and digitizer already glued into a new front body piece: http://cgi.ebay.com/OEM-HTC-FUZE-LC...wItemQQptZPDA_Accessories?hash=item3ef8817bf6 That one's for the fuze, but I think the seller has other models too. I'd definitely get the LCD and digitizer together or else you might end up like I did on my first attempt: http://forum.xda-developers.com/showthread.php?t=584050

WOW! What a long way to get to the screen. Good luck for everyone who tries to dismount and mount the Raphael.

Thanks for the advise maxh,
I just wanted to let you know that a miracle just happened! my cellphone started to work just fine without even opening the phone! it has more than a week on this situation so I believe that it's exactly what you stated (the LCD conector became unseated or loose). Since it's still working, I have no need to open it! so I'll just wait until it becomes defective again and at that point just open it and tight up the LCD connector!
Anyway, I would love if somebody could make the mod that I was refereing to before (changing the screen of the fuze by the touch pro one) and see if it's possible to attach the front camera on the fuze.
Once again, thanks everybody for your opinions.
I got my new display+ digitizer on Ebay (65$) and replaced it, using the russian link mentioned above ( follow the exact procedure) , it took me 2 hours to do it, and after lot of patience it worked! My problem was the digitizer never worked fine, and after replaced it it worked like never before. If You are not familiar with repairs, it will be a mistake and waste of money to buy a display without digitizer. NOW, I have a small problem, my display has a NEW color, it's like color temp is WARM for this display, and COLD for my old display, AND COLOR level is lower, and the result is display without vivid colors, black like gray. Is there any way to change the DISPLAY color settings?

navigation button are not working

Hey
few days ago my HOX ATT fall down. all the buttons were ok but after some days they had stopped working. i have tried to do factory reset but it didnt helped. all the touch screen works but the buttons not. i sent the HOX to Repair shop and they told me they have not seen thing like this before that only part of the touch digitizer working.
can you help me solve the problem?
Thanks.
The fact that the repair shop has never seen it before, does that mean they won't even try to fix it?
He said that he need to order this part to fix it and he even not sure that it will work.
is this hardware problem?

Since you dropped the phone recently, I'd be inclined to say yes.
I'd try to RUU, and if the problem persists, its probably a hardware failure caused by the drop.

Please search the forums regarding LCD changing. It's not an easy task.
http://forum.xda-developers.com/showthread.php?t=1720900
You must buy the entire LCD - Digitizer -light guides bundle . It's almost impossible to separe the screen from the LCD, so buying the digitizer is a waste of time if you dont have the LCD.

the same thing for me, i have tryed everithing and not fixed yet, in a few weeks you will see how other parts in the touch screen will not work too.
As javierarenas has said, Purchasing the digitizer alone is a bad idea. Nearly impossible is an understatement. even with a heat gun and an unlimited amount of patience you would be lucky to separate the digitizer from the LCD.
As Redpoint said, if RUU doesn't fix it, you will need a new screen.
Take the phone apart prior to buying the screen. Check the colors of the ribbon cable and try to find the EXACT same screen. This will save you a lot of trouble. Make sure to keep the old screen in case you need to sync the new screen otherwise you are totally screwed.
Good luck.
I tried taking apart my phone and it was not an easy task.....AT ALL! MAKE SURE TO BE PATIENT!

Funny thing is I never had to take mine apart. But did have to reattach the screen, sat down with phone in back pocket and when I pulled it out it had separated the screen from body and had to use some iPhone screen double sided tape to glue back down.

One Plus One Touchscreen

Hey guys, I want to buy a "defective" OPO for 100$. The sellers told me that a part of the touchscreen (about 13%) is not working. He says it works every once in a while but it is really rare. I was wondering if I would be able to fix this trough a Kernel or a ROM update (he runs CM12S) or if I need to change the screen completely. The guy says he had the phone for 2 months and he hasn't try to fix it because he has an iPhone (LOL)
Thanks for your answers!

Don't think how low u have to pay for opo but must think is it usable
Nearly 20% users complaining about touch issues like
1)ghost touch
2)unresponsive screen etc
http://forum.xda-developers.com/oneplus-one/help/ghost-touches-invisible-finger-t2832822
OPO tried to solve this by firmware updates but they still not fully able to manage it
New firmware with improved kernel solved lot more touch issues but draining battery a lot for most people's
So its u r decision buy or not to buy but three possibilities are
1) buy if u don't care about u r money if problem not got solved
2)buy if screen problem is not due to any hardware issues because if yes u have to replace whole screen which cost 200$
3)if its software problem then u should know most of android rooting/ flashing /custom roms/custom kernels to recover problems
If its software problem then these are some solution

I bought an oneplus one with a broken screen on ebay.
Bought an replacement display with frame and some cheap tools for 50€ on aliexpress.
Replaced the broken screen + frame withing one hour. It was my first attempt to open up a smartphone ever.
Only problematic part was the earpiece, which I almost destroyed.
And also the lower antenna (which is fixed with double sided adhesive tape) bent a little bit.
But besides that it was very easy to dismantle the Oneplus One and to replace the screen/frame combo.
Compared to my other One the new screen looks absolutely identical. Only the earpiece grille is slightly different.
So. My conclusion. If your are able to unscrew a smartphone and are not completely lacking fine motoric skills, you can have a cheap Oneplus One. Watch the tutorials vids on youtube and the photos on ifixit.
cheers!
Edit:
Ah and yes. With my One the screen was shattered and not working.
So I have to agree to my previous speaker. It could also be some other part of the hardware not working. It's always a risk. But I assume, that by replacing the whole screen/frame, probably the digitizer problems should be solved.

I also wanted to mention that I also experienced ghost touch issues with my first Oneplus One.
Thats why I orderd a replacement screen in the first place. Then, in the meantime, until the display arrived, Oneplus released a firmware update and my ghost touch issues vanished.
But. I never had parts completely not responding on my screen. It was "only" a ghost touch issue.
i have it
Hey guys, i finally bought thé phone and the u, thé j and the n keys works 1 out of 10 times. Si it is not completely broke. How tout dix that?
Download YAMTT from play store. Test if you can paint everywhere on the screen.

no I can't there is a small bar on the right that is not working
Probably a broken digitizer. I.'ve never read of anybody fixing this with a Software update. On the other hand, I'm not an expert...

Fingerprint module disassembly

Hey guys!
Unfortunately, my Honor 8 battery cover broke a few weeks ago. Now I've received my replacement part.
There are a lot of dissassebly-guides around, but none of them shows how to remove this module from the battery cover.
Can anybody tell me how the fingerprint sensor is connected to the battery cover?
According to this picture it seems that it is fixed just by adhesive:
http://www.myfixguide.com/manual/wp-content/uploads/2016/08/Huawei-Honor-8-Teardown-10.jpg
So I am not sure how easy it will be to get it out (and in again).
Any guide or ideas on that? Maybe anyone of you already had to deal with it.
Thank you.

if u r not sure , dont do it ur self , u might brick something . give to pro of service center .
Thank you for your answers.
Well, I understand your advices, but this is not the first device I repair. I have experience in fixing broken displays, ect.
Anyhow, before I start, I always want to get an insight of what to expect. For honor 8 it seems quite easy to remote or change the battery cover, the only uncertain factor is how to swap the fingerprint sensor, because I've never dealed with something like that before.
So I appreciate any information on getting the fingerprint module from one battery cover to the other. If there are high chances to brick it while removing, I would buy a replacement module beforehand just to be save.
Thanks.

S3 frontier bezel

Hi.
So yesterday I got my watch back from an authorised repair shop that changed my battery, cost me about 80$ and they manage the lose my watch and return someone else's.
Got my in the end but someone over there manage to do something to it and I don't want to send it back to them.
My bezel seems to react but only change one screen, and then change back to the previous screen when I keep rotating it. If I use my finger it will change between all windows on the watch with no problems.
No strange sounds and feels the same.
I Googled it and took apart the bezel, cleaned it and put it back together, but problem persist.
All 4 balls and pins where there and the watch is clean to.
Tried to hard reset it but problem still persist.
About the watch:
Sm-r760
One ui 1.0
Tizen 4.0.0.4
Software r760xxu2esf2
Hope someone got a good idea.
Never tried... no idea yet...
Only you allready checked Videos on Youtube?

The bezel includes 8 magnets to work like a quadrature incremental encoder.
The magnets may be got demagnetized somehow. Say, the previous owner was put into a MRI scannrer with the watches or lived for a long time in a transformer box.
There's nothing you can do about it, just replace the bezel. Or the magnets, if you manage to.
