Apple Watch Series 2: Apple Watch Series 3 screen replacement

Tue, 26 May 2020 06:08:14 -0700

Hello people from ifixit,

I need to know if the complete screen from Apple Watch Series 3 is the same as Series 2 and can be replace one for the other or need to remove some flex or IC from one to put in the other. Some people tell me that need to change the NFC IC.

Thank you

Hello Dan, and thank you for you're quickly answer.

Really what I need is a technical opinion and not about warranty coverage because I have many Series 2 from many customers with crack screens that need to be replaced.

But no one has big quantity of Series 2 complete screen on the market to buy. For this reason I posted the question. My supplier in China who I did buy many Series 1 complete screens (hyper-trustable) tell me that the LCD & Touchscreen module is compatible.

But, need to replace a flat ribbon cable with some component that are glued on the back side of this module, they call it the NFC IC but I don't know really if is trueIy inclusive in the Series 3 teardown description the IFIXIT team wrote this info: "Spec-wise, the display is unchanged from the Series 2, with one key difference - it now functions as a multifrequency (LTE?) antenna. We'll be testing compatibility to see if the displays really are interchangeable."

Based in this info I believe that both are compatible.

Thanks

Samsung Gear S3: HR sensor not working

Mon, 13 Sep 2021 13:49:02 -0700

As per title, HR sensor not working at all, tried soft/hard reset, re-pair doesn't help as well.

Wake-up gesture not working too, the watch seems to be not able to detect my wrist without HR sensor, no matter how hard i swing my arm the watch just won't turn on itself. Sleep monitor stopped working too (probably due to HR sensor not functioning)

what could be the cause? device was connected to samsung note 8, thanks in advance.

Purchased watch but turned out to be a demo watch.

The retail mode app is there. 5444 gets you in but when you select off for the retail mode it goes to the Home Screen and does not turn off.

There is another factory reset screen in the Retail mode app but it prompts for a password when you try and reset.

Apple Watch Series 3: Apple Watch series 3 no touch after screen replacement

Tue, 03 Dec 2024 02:43:29 -0700

I recently replaced the screen on my Apple Watch series 3 Nike + edition. The screen comes on and the buttons work but there is no reaction from the device when I touch the screen. I have tried force restarting it dozens of times and it has changed nothing. The old broken screen does not work at all so I believe that trying to use the old digitizer will not work. Anyone have any ideas?

Samsung Gear Fit2: Replacement Charging Pins Badly Needed!

Tue, 10 Mar 2020 18:22:43 -0700

I need to replace the badly corroded charging pins on my Gear Fit 2.

It was a gift for pre-ordering the Samsung Galaxy Note 7 (That I still have), and I'm pretty sure that Sammy (Samsung) will not replace, or fix the device without me first returning my Note 7 (which I have no intention of doing so).

Is there somewhere (Amazon, Newegg, E-Bay) where I can purchase a replacement?

I'm an IT professional who has no problem tearing this thing apart and rebuilding it myself, but I just need to have the correct replacement parts on hand before doing so.

If anyone can provide me a Part Number, or the correct name of the circutboard that I'm replacing; that'd be most helpful.

Thank you in advance.

Apple Watch: Will the Apple Watch sapphire digitizer work on apple watch sport?

Fri, 01 Nov 2019 21:16:54 -0700

Greetings!

I work as a repair technician and I am now looking into Apple Watch repairs.

One thing came to my mind: I'm sure people would, if they had the option, rather have their broken Apple Watch Sport Ion-X glass screens replaced with a sapphire glass instead of the Ion-X glass.

But.. Will the Apple Watch digitizer work on Apple Watch Sport?
