[Q] weird lines on screen

This is a chinese s4 phone, after dropping it glass broke and screen displayed these lines as shown in pictures. What i want to ask is should i change the glass only or does it need a new digitizer? touch screen responds well, no problem there. just these lines. anyone have any clue if this can be fixed without changing the digitizer?

Change both digitizer and display

It's clearly that both are broken - and the digitizer is glued to the display, so you must change them both.

Thanks for your fast reply So do you know maybe if i can find a cheap chinese digitizer? not worth buying the original one which probably is not compatible, correct?

Look on aliexpress.com they have cheap digitisers and glass

Since this is fake Chinese S4 it's a real miracle to find part which is for your phone and one that works. LCD and Digitizer (glass) are not laminated in your case, so replacing them should be easy.

Don't think there would be a screen from a chinese knock off, and furthermore most of those parts aren't even genuine Samsung parts.

so not worth repairing a fake phone assuming you even can. buy something half decent at a 2nd hand store. hope you looked for malware on that phone before you started using it...

The glass might be glued to the digitizer, but it can also be unglued.
Take a blow dryer, set it on hot air and blow dry the phone. The glue will heat up and become liquid again. Use a guitar pick and try to pry the glass from the screen and slowly pull it off.
I've seen this being done once (on an original S4), so yeah, I'm sure it is possible.
After the glass is off you should see if it still has those lines or not.

[Q] Dust under new glass replacement, how can I remove it?

Just got a few weeks ago my I9505 from a repair centre.. I cracked it's glass and got a replacement for around $40.
I can clearly see a lot of dust under the glass, above home button. I think it also penetrated below back button.
The touch works fine in the rest of the screen, only in the parties mentioned above it doesn't, works hard sometimes.:crying:
My question is: Can I remove the dust without cracking the glass? I don't want to buy a new one..
I heard that you can heat it with a hair dryer and pick just the glass up without cracking with metal tweezers..

Well i suppose you didn't go to the official service of samsung because if you have gone, your service would cost 160$. So it's a second man job. You can go and tell him to restick the glass only or you can search on YouTube for a tutorial to do it by yourself... I prefer the second one. I don't trust anyone, only me!

At first you have to go o your service guy to mention your problem. After that,
if he won't do anything, you should buy a 2 mm double sized tape from eBay. But you must be very careful. The guy who changed your screen isn't the certified one huh?

[Q] HARDWARE Please look at my photo and tell me if my phone can be saved

OK I'm an idiot I destroyed my digitiser when trying to do a screen replacement on my S4. Can someone please have a look at this pic and tell me if (apart from the broken digitiser) I have damaged anything else that would make digitiser replacement no longer viable?
Thx very much for replies

It's not just the digitizer that's toast, but the AMOLED screen as well. Those cracks near the upper right are where the screen itself is broken. With damage to the screen you're going to need to purchase a new midframe with screen and digitizer already attached to it. I don't know how much you spent on your glass, but the midframe and screen are going to cost about US$150.

Thx for reply . Could you just tell me if this is what you meant about what I need to replace the damaged parts?

Thx ever so much for help

That is precisely what I meant. It's the entire screen plus the midframe. You'll need to pull all the sensors and other small bits off the bad screen/midframe and put them on the good one, as the replacement part doesn't include the sensors. iFixit should have a breakdown guide you can use that should be of help.

Oneplus Two Screen replacement

I broke my OPT screen when I dropped the phone. I ordered a replacement screen on ebay and disassembled the OPT using videos I found on the internet. The OPT was relatively easy to take apart.
The replacement screen arrived. When trying to place the replacement screen into the frame, I noticed that it lacks the glue on the edge of the screen to attach to the frame.
Any ideas on how I can attach the replacement screen on to the frame? Is there any glue that I can buy? Or will regular glue like super glue(permanent glue) work? Just don't want to risk damaging the replacement screen.
Any ideas?

Thanks for your reply. Anything in particular that you recommend? A link will help me.
If I order online its going to take alteast a week to ship and receive it. There is some urgency to fix my phone. I need to fix it up before an upcoming trip on this Sunday.
What will happen if I use superglue to attach the screen to the frame? Will it damage the screen?

I'm sure what kind to look for but they are all over eBay and for superglu I'm not sure what will happen but I'm sure there a reason why they don't use it in the first place

Hello all, I went to a local store that repairs phones. I asked to if they would sell double sided tape and offered to pay a nominal fee. They were kind enough to give me a few and at no charge. With this I have put back my phone in working order.

In how much did you got your replacement screen???, I also broke my opt, it's easy

Sorry, have not been on xda in a while. I paid about 25 USD on ebay.
Its pretty easy to replace. Takes a lot of patience.

Since the thread has been revived already, I'll drop in my $0.05 since I just replaced my screen last week
* The assembly/disassembly is fairly easy following video tutorials, it's not even necessary to remove all parts if you're careful with the heat.
* Remember to move the fingerprint sensor, the glued-on touch buttons and the phone speaker cover on top to the new screen.
* As always, you need to be patient when heating and ungluing the old screen from the frame (luckily it's glued only on the borders).
* I got my screen from aliexpress just under $20. Couldn't find any difference between it and the original one.
* As previous posters said, do not use any cyanoacrylate glues (superglue, etc), they leave white stains on the glass.
* I was also surprised by no glue on the frame I didn't have time to order adhesive strips, used a really thin layer of silicone adhesive, worked well and there are no gluing signs.

Glass with the LCD. I think replacing only the glass would be very hard, if even possible without proffessional tools.

It certainly looks the same, both internally and running on the phone, compared to my gf's OP2 which still has the original screen.
I bought this one, but I guess all the aliexpress screens are the same

I dropped my phone too sadly. Contacted the local repair centre and they said I do need to replace outer screen and the digitizer. And the process is more than $100 if I convert it.
In Alixpress just about $5 for the outer screen. Do I need to replace both or just the outer screen?

I don't think changing just the glass is a good idea, I think there was video of a guy trying and braking everything. Just like the guy before said buy a screen for $20 and follow a guide. I also broke mine, but ordered a screen + frame for $50 because I thought it would be easier to just move the hardware.

Adhesive for screen. I've changed my screen twice.. Mr. Sloppy hands -.-

Broken screen

Unfortunately my screen broke, the LCD is working fine, and recognizes touches.
Is it possible to change only the glass and digitizer? Eg
I'm afraid of LCD panels from eBay. The service said that warranty is void at all events (even if they repair it).

I'm currently in the same situation. Any update on your phone's screen?
A local repair shop can't fix it unless I buy a panel myself and let them fix it for me. I want to know what I need if the glass is broken, but touches and LCD are fine: just glass or a complete screen replacement, like this one: https://www.aliexpress.com/item/Rau...Panel-Replacement-for-Xiaomi/32835465822.html .

I will order a complete LCD panel with frame and try to replace myself. But I don't know if they are the same quality as original.

Let us know when you do! Please also specify which replacement you bought. It's a good idea to document these things, because in the coming years many more people will break their screens, unfortunately, but we can help them finding out what screens are worth buying.
I'm especially interested in touch performance and LCD similarity to the original. If you could pay attention to those properties and comment on them when you know, that would be really helpful.

Never try replacing one yourself, no matter how tempting and easy it looks on youtube videos, without proper gears and experience, you will end up damaging the whole panel. I know because I tried and failed myself and ended up buying the whole front panel with the LCD.
It will be much cheaper to buy it off ebay and let a experienced guy do it.

Did you tried with LCD+frame kit? It looks much easier that way. What happened exactly?

I was trying the glass with digitizer which was pretty much cheap, which needs to be removed with proper gears and lot of patience with a heat gun(I have seen local shop guys doing it without them with ease), It was an old samsung s3 which I kept to experiment on, ended up buying the whole front assembly which I did installed successfully(made me feel a lot better). That looks easy and there is less of chance of any breaking, unless you are very careful in removing all the tiniest sensors and wire and put them accordingly, but then you have to carefully pick the whole assembly there are plenty of low quality ones around, where you might get one that gives issues. for instance on Samsung s3 it was an original amoled display. but I got one that was an LCD panel display and there were issues where brightness sensor didn't worked at all.
Your best bet would be an original LCD+frame kit, I don't know if you really can get one off ebay.
So my three advices.
1. try to get only the glass with digitizer off ebay(If your Display works), then let a local expert change it. much cheaper and let you avoid getting a low quality LCD panel.
2. If it's your first time, I would suggest doing it on a cheaper phone to test your skills, I wouldn't recommend doing it for first timers who have no experience of doing it. there is high possibility that you might break a sensor or a wire.
3. if you want to go ahead with a whole new kit from ebay, make sure you check it without removing any sticker, and connect that display with the motherboard and see if the display is really good and make sure you check the brightness and touch. only if you are satisfied then go ahead, or return the product.

Thank you for the advices!
I couldn't find anybody, who can replace only the glass and digitizer.
The screen and digitizer work fine, only the glass is broken.

I saw MiA1 LCD panel, Touchscreen and digitizer which is around $39-$46 on ebay, while I couldn't find just the glass with Digitizer. I think the best bet right now would be with the full kit with LCD. as they aren't selling without the LCD at the moment.
Although I would suggest you keep the original LCD panel with broken glass,(don't try to remove it yet, let the glue wear off itself until then) in case they do start to sell in future the glass with digitizer only. There could be a next time(who knows? or you can just sell that to someone), where you will at least have an original LCD, these things break very easily. be sure to keep them safe, and if you feel confident enough, you can try it yourself, just be careful with the glue, and the pins. go gentle, it's a surgery. best of luck!

I love advices like that.U r smart.

I've also cracked my screen.... happened yesterday when I accidentally dropped it on concrete. Touch is working fine, only glass is broken.
So would be buying only the digitizer like this one: goo.gl/ZDPoFd do its job if I let it do at the local repair shop or buy the whole LCD as mentioned above?

You're going to need to ask your local repair shop. Some shops will be able to replace the digitzers, others only do the full LCD assembly. Again others will not even accept repairs where you bring in the parts, they'll source the parts themselves.

I've contacted a local repair shop and said they couldn't do only the digitizer, but they can do the whole LCD repair which will cost me 25 euro. Now I have to find the right one..... as you have so much variant on Ebay and Alie. U have a suggestion on which one to choose?

My MI A1 display is craked .but display is working and phone functions are working .just I ask you if I using the craked display for long time is it problem come.phone sold 3 days ago so I cannot want to repair the lcd. .Plz advice

I bought this one: https://www.aliexpress.com/item/Ori...izer-Display-For-Xiaomi-MiA1/32831902856.html
I let a local phone repair shop do the repair for me. They did a great job. The screen itself is also great. I think it could be an original, as I can't tell any difference. The colours seem the same, it measures up to 10 simultaneous touches (like the original), the performance feels identical. I recommend this screen! I've also left a review with pictures on Ali Express, but it's still being processed.
I ordered a white screen for my black Mi A1, so now I have a stormtrooper! (or panda, whatever you want...)
Screen plus repair in total about €60, well worth it IMO. It's quite a fraction of the original purchase price, but hey, I shouldn't have dropped the phone after a month. I've also ordered a plain black back cover to help me better grip the device.

I didn't know that! It wouldn't have been bad, because I don't like the button backlight at all: it's on for too short, it's too bright, it's not like I can't find the buttons and it's not like I don't know what functions the buttons have... I hope we can turn it down or off in the stock ROM in the future!
