S5 lcd/motherboard - Galaxy S 5 Q&A, Help & Troubleshooting

Hi guys
Iv dissided to repair my s5 as a spare mobile.
I say repair because the screen rotation stopped working a long time ago. I tried all the suggested ideas. Now the charge port has gave up.
So Iv been keeping my eye open for one that works with a smashed lcd, with the intension of using the motherboard from it to rebuild mine. Today I was offered a s5 sm-901f.
My s5 is a sm-900f.
From the spec and pictures Iv seen Iv got a feeling it would work. I'm assuming the motherboard would also fit into my housing, as my phone is still near mint condition.
So basically its putting a 901 motherboard into a 900 housing with a 900 lcd.
At worst it would be putting my 900 lcd on the 901 housing, but the housing is pretty bashed up.
What's your thoughts, will it work?

O2 Atom Pure - Shaky LCD Screen

Hi, I am currently using O2 Atom Pure and I had to replace the old LCD screen because it was shattered into pieces. I bought one from eBay a while ago and managed to get it replaced, however, since the replacement I have realized that the LCD screen keeps on shaking every now and then.
Why is this? and can this be fixed?
Thanks
might be a loose connector to the mainboard
Its not the connector problem...I think the atom is sensitive to some radiation...I live outskirts...Whenever i go to the city this happens...Dont kno why...Same problem....The display viberates...But I dont mind It....It happens for shot period...

New Digitizer doesn't work??

I recieved my new digitizer today and i carefullt opened up the g1 and swapped out the old cracked screen for the new one and connected the ribbon. The dang thing still doesn't work. I tried re-imaging to RC30 and still no luck. I ordered this screen from Hong Kong.
Thanks for any help
they could have sent a defective one, thats gotta be frustrating.
how did you initially test to verify the digitizer was bad? I assume it wasnt just cracked because they usually still work. There is a very good possibility that it is not the digitizer, it could be software or other hardware causing the digitizer to not work. My money is on one of the flex cables.
I got the phone for free from a friend in PA and i lost 30 bucks on the screen so im not out too much. Hey guys thanks for your thoughts
Sounds like it was something other then the digitizer, maybe when that got cracked something else got f'd up. I hate ordering anything from honk kong, I always check the north america box on ebay. Even if it costs me an extra 10-20 I don't mind cuz out of the 8 times I have ordered from HK 5 items have been defective and only 1 of those sellers got back to me and replaced it. Plus your lucky to get someone who is fluent in any language besides there native.
These are notorious for the flex cable between the front and rear housing breaking. It is a terrible design. Try replacing the flex cable and I am sure you will find that it will work again.
Hey! Old thread but I just took apart my phone so I'm prepared when my new housing arrives. Anyways I put my phone back together and my digitizer that Im now typing on didnt work. So I took the phone apart, made sure I had the ribbon for the digitizer on. Put the phone back without the screws. I then turned the phone on. Digitizer worked. Put screws in. Digitizer stopped working. So I loosened the 2 top screws 1/4 turn and BAM.....Digitizer worked again.
Hope this helped.

Samsung Galaxy S6 Teardown

http://www.myfixguide.com/manual/samsung-galaxy-s6-teardown/
Doesn't quite show if the Modem is a separate chip or onboard the 7420.
my 2 cents
Was just about to post this. Thanks!
The battery seems cumbersome to replace. I hate heating things up and removing the glass in fear of cracking it. However, once past that, it looks pretty standard. I'm glad there's no more glue underneath that all.
Being careful, it can be "easy" to change the battery
There is a YouTube video about The Galaxy S6 teardown

Parts list for SM-G920I
I wish it was a little easier to repair, ala the Nexus 4, which was rather simple to take apart. But really, anyone who has taken apart phones before shouldn't find it too difficult to repair this device. But it looks like most everything is soldered to the motherboard. What will happen if the usb port breaks?
Hi. I just broke my S6 display, just the protection glass ,the touch is working flawlessly even where the display is cracked. I was wondering what do you suggest, to change only the glass (Oca glue /gel ?) or to replace the whole display meaning glass and touch? Please help guys. Later today I will post a picture with the display. Thank you.

I only had mine for 5 days, dropped it, and cracked the glass.... a week later, dropped it again, and cracked it even more! I can't believe how slippery the G6 is. Anyhow, I ordered a good case the same day I got the phone, but it's stuck at friggen customs for over a month now... Soon as I get it, going to get er fixed. It's $210 locally rite now to get the glass replaced, or $150 for an insurance replacement. Regardless, going to stick with the messed up screen til I get the case, still works great.
Hi. I found to replace the glass and touch together with 150 . Replacing just the screen I think it's cheaper but I didn't hear good things about this procedure (high possibility to crack the touch or the gluing of the touch and glass it's very hard to get like new). Where are you from? http://www.amazon.co.uk/gp/aw/d/B00...y+s6+parts&dpPl=1&dpID=51nFR7qIK9L&ref=plSrch
I bought a Samsung Galaxy S6. The other day, I happened to break the front glass. The LCD is still fine and the phone works, but the glass is all cracked and a little sharp. So I got a Samsung Galaxy S6 replacement and then followed the video guide to fix it. Now the phone just like a brand new phone.

[Q] Galaxy S4 i337m switch digitizer with a clone?

I've ordered a used Galaxy S4 on Ebay and received a cheap clone that i'd never used has my own device. It's one from Mediatek and i was wondering if i can at least use it's lcd/digitizer with a legit S4 i337m because i have one with the screen broken so i would at least not be losing everything on this? If not i'll just ask for a full refund and send it back to the seller.
no you cant the flex cables wont even be the same and i mean flex clabes as they are two different cables when the original s4 only uses one that connects to the logic board. the digitizer es integrated into the lcd screen and the flex is connected directly to the lcd screen on the back. It would have been alot better if you would have bought an lcd display for you model. and if you dont know how to take it apart you could buy one with the bezel for your model number. They sold me an lcd screen for 400 pesos and i replaced the glass using uv glue and it works perfect. and was a cheap fix. maybe you have a friend with a dead logic board and working screen or cracked glass where the lcd digitizer still work you should ask around may be cheaper with money on hand

It depends on if the clone uses a digitizer with the same connections, but most likely not. You could open them up and check if the frames and connections are the same, but each model S4 has the digitizer connections in a slightly different place

[Q] Question doing full glass and LCD replacement on ATT S4

I purchased a replacement LCD and glass + housing for my broken s4.
http://www.amazon.com/gp/product/B00JB0YX58?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00
I went to work disconnecting the old connectors, MB and parts. When i was done the old phone and new phone looked exactly the same, except the old one was shattered. i installed all the parts and snapped it together, and it would seem i was done.
When i booted it up there is no display on the screen, although led lights turn on and i feel the vibration. No sound, and no picture on the screen. but i think the phone is on although when i make a call to it i could not tell if it was ringing. I feel the vibration kick in when i hit the down volume a few times.
Any help be greatly appreciated!
I`ve done glass screens on more Samsung galaxy phones than I can count, but not an LCD as the digitizer is not connected to the glass and does not need to be replaced unless it is also damaged. I can offer this, however (and hope it helps); I did an LG G Pro a while back, and their digitizers are built into the glass (therefore connected to the MB). It was an AT&T specific device, and the replacement glass was a universal replacement. The fit was perfect, but because the digitizer ID didn`t match what the processor was expecting it wouldn`t come on. The drivers aren`t compatible. I later learned that many AT&T devices have similar trouble with aftermarket parts. I have since repaired that same LG several times (not the most durable device I`ve owned) with AT&T compatible products and it`s been fine. If you`re just replacing broken glass, you can do it without replacing the LCD. It`s a time consuming PITA but once you`ve done it once it`s pretty swift from there on.
Again, it may not be the problem, but hoping my experiences will help.
