First, sorry my english. If anything is incomprehensible, ask me.
Not long ago I dropped the device and fell to a gravel, not defended by the ?Gorilla Glass. It became a spider web. Essentially, the device was working, sensing the touch, and the display was relatively intact in just one spot a little pressed. I ordered a replacement part from here, because the glass also fell and because it couldn't stay. I chose express delivery, stuff arrived within 1 week. I have made it difficult to disassemble the device because the back is glued together. It didn't want to come down, I tried all kinds of plastic tools they had given and what they were, but the glue was so strong that they all broke (I'll be curious to know how to put them together). I had to use a paper cutter, because it is sharp and goes into the gap. Unfortunately, the breakdown at the corner is slightly visible, but it must be as much trouble. Luckily the adhesive came out of the battery. (I will also have to order it from somewhere for rebuilding ). The main panel also came out of the house nicely. If we are already here, I removed the unwanted heat conductor paste and replaced it with quality Grizzly.
The display did not want to come out, it glued to the frame so strongly that it was impossible to remove it. I managed to do it in pieces, and I licked the remainder for half an hour. Worse, there is something new, no matter. Then I realized that the new one had no glue, and that the old one could not be removed because it was not an adhesive, but something like a very thin siloplast. I have injection needles and black silo, so I can make up. No loudspeaker lattice was added. I hope I can take the old one somehow to stay together. And here comes the black soup:
I plugged in the cable and turned the phone on (not screwed up with just a few screws to hold it). I have a picture, I started to calm down. Need to unlock it, but don't works, it don't feel my finger. Nowhere. If I remove the factory foil, either. I looked at the stuff in more detail. The photo already shows that something is wrong in the lower right corner of the display. The original has a large square-shaped Synaptics S3330 chip, the touch panel controller (like Mi 5). However, this is missing from the replacement device, with a much smaller IC of "S20A X705E24". I have no idea what it is, but it is also suspicious that a ribbon cable goes below the original and there is nothing there. But on the site of the seller there is also the ribbon cable in the pictures and it is highlighted as "Multi fingers touch chip". This may be some great big scam. However, if it have a Touch controller IC and something that is supposed to work in principle, then the Synaptics driver (kernel module) is loaded on Android. I suspect that then this IC should get the kernel module somewhere and should be loaded to work with a rooted device. But I also thought that I would try some other rom (AOSP, LineageOS) and see if it would go with it, but chances are that Recovery would not work with a USB mouse + keyboard. Maybe there are different hardware versions of Chinese and global versions? Because it is possible that Chinese (or eu) would work.
I wrote to the seller that the stuff wasn't working, he said I would remove the connectors with an alcoholic cloth (of course he didn't help). Until then, the time was up to 15 days, so I can't start a dispute. He asked me how he could help, I wrote to him that I didn't know but I needed another display in this device. I wrote to him that he might be able to return my money or send another display. He said that if I stood at 75% of the cost then he would send a new one. At first I would have gone into it, but now that I've examined this and it turned out, I wrote it and sent the picture as well. I don't expect anything good.
I found another seller that is already fitted with the frame (minimal more expensive), maybe there shouldn't be any fun with gluing, I could do better if this is not solved this way.
What do you think about this whole thing?
That gold one is dor mix 2,and that black one is for mi mix 2s, right?

Cliq (original) running most recent stock update.
To start, it is not cracked, shattered, or fully unresponsive. Only the right 25% of the screen does not respond. (Making some letters useless, and unable to press "Clear" on status bar among the obvious feature losses.)
While I have not taken it apart to verify that the ribbon is fully seated, (possible cause, along with it is just broken) I figure if I am going to take 3 hours to disassemble, I might as well have a spare digitizer to put into it...
My question is this:
Is there a way to calibrate the screen's display (by app, or ROM) to shrink the screen to where I can actually get to all the keys? [Calibrate the screen edge, as with the old style monitors.]
[I will root/flash ROMs/kernels if there is a viable method. Good with computers, new to Android, but I'm game to risk my $30 to get a working backup!]
I figure take out 25% of the top and right side and then even when the phone shifts I can still touch everything... Would turn the phone into a viable replacement.
The replacement is $25, after 3 hours of dealing with T3+T5 screws... on a phone worth $50-75.
Thanks in advance, new poster for the most part, but I frequently use you all as my Android Rolodex.

[PS. should I feel like worst case this is a few command lines that skip a pixel every a few lines on both output and input. This may be more complicated than I think it is, as there are always bugs when you think of it like that, but feel like this is close to method the fix must use, but perhaps less precise.]

Granted this is sped up and all, but the process will not take 3 hours. I did this ony my hero cdma (essentially the same process) and it only took me ten minutes (i was being very slow and cautious). I'd say just go for it because it is worth it. My screen was not cracked, i only took it apart because i am painting it....not done yet but definitely getting there. I also noticed that after taking apart the phone and putting everything back the phone was actually more responsive. I guess over time of use, things start to move ever so slightly and this tends to make parts of the screen unresponsive. I'd try taking apart the phone then putting it back together and see if that helps (sorta like recalibrating it) and if not well then buy your screen and put it in. Hope this helps

But yes... OK will I will look for my microscopic set and see if I can't knock it out before bed. (My deconstruction experience is usually limited to replacing springs in Nerf guns!)
[Edit:]
Meh, my dad's set has disappeared (but smallest was T4 anyways). Tried the melted BIC pen that worked for the tri-tip, but T3 has too much detail. I ordered the tips I need from China. I'll update with my results in a few weeks.
I had a problem with my touchscreen in my Motorola Milestone xt720. I found it out becouse few areas of screen didnt respond. So i bought the Isopropanol and i washed every single part carefully. After drying and putting parts together it still was the same, additionally I noticed, that when pushing the screen near the ear speaker the touchscreen behaves otherwise, or works as it should. Than i took the parts off again and watched the tape. It was torn (or broken). Than i ordered new digitizer on Ebay. After replacing the digitizer and connecting parts again it doesnt power on, and even do not enter in bootlaoder mode. I think the LCD or any single part isnt connected wrong, becouse phone should vibrate and give sound while staring. What can i do with home remedies? Thank you in advance for the answers
If you were the one who did the assembly yourself, you should be aware of ESD. Have you tried reconnecting the old digitizer? And this time, ensure that you are shielded if you weren't (ESD straps). ESD can turn your unit into one real brick, so be careful.
i think you have bought a different digitizer that is not compatible with xt720,
there are similar digitizer with milestone xt720, like;
motoroi xt720 - looks the same but different hardware.
moto xt711 - looks the same but different hardware.
moto xt701 - looks the same but different hardware.
or maybe you have bought a damage digitizer. :-(
@Similya: I dont think so that digitizer is wrong, becouse it looks not the same at the visual point of the front but 100% the same from the back while watching the touch paths, and the tape with connector. Anyway there is not any other looking like my stock on ebay (mirror effect, and other button icons on the top), and the seller got ~99% positive grades with comments reffering to the "Milestone XT720 Digitizer Auction" as "It fits well and works great", "A++ Grade. Fits fine and working.", etc. So i think i have chosen the good one.
@pakpaker: I dont know what is it but i will google about the ESD, i hope it isnt too late ;/
And i cannot connect the old diditizer couse i threw it to the trash after comparison to the new one. Should it start when i just disconnect it and run?
edit: ok i know what ESD straps are, but i was replacing some parts in phones without it and everyone works fine ;/ and the digitizer looks more like the 701 / 711 one but everyone who is selling them says that fits to 720 and customers who buy it gives positive opinion and comment like "it works well". So what is going on? If it is not the proper one, shouldnt it start but just digitizer does not work?
just to make it sure, just bring your phone to a cellphone technician for a better check up. just avoid touching the chips and board. it might catch an ESD from your body. ESD can damage the cpu, ram and all CMOS chips.
by the way, what rom you are using.?
I was using stock rom 2.1 + root and some mods
Ok i will try to find someone but just cant believe that ESD may cause any damage. It has very high voltage, but extremaly low current, so that charge may not pass over any integrated circuit. I think it is only balancing the charge between item and hand, and those ESD straps protects technician against high current from other items which are working atm ;]
Picked up this phone from CL. The person was claiming that part of the screen is not responding to touch.
I have seen it when I picked it up, but I thought that I will deal with it when I get home.
I was keep playing with the phone almost everything it's working on it except the volume buttons and that horizontal line where the #456 is on the dial pad.
I have removed the battery and noticed that the white sticker it was pink, water damage.
Now I don't know what could be the damage here? There is a shadow across the screen also, but it's not a crack.
I have seen this before on a digital camera, it was the aluminum sheet metal under the LCD, had a smudge across on that aluminum finish too.
Couldn't remove it though. Replaced the screen on the camera and it was as new.
Not sure what could be the problem with the phone?
Should I replace the digitizer, since the LCD shows everything correctly? It could be something shorted internally? I have the phone apart, but I don't see anything wrong. Cleaned all the contact with electronic cleaner, no change.
Any help would be appreciated.
Please post all questions in the Q & A section. Thanks! Thread moved.

I think I would replace the LCD and digitizer as a unit. The slightly higher cost would be easier to accept than having to do it more than once, which would probably end up costing more. Either way is a gamble, though, because that might not be the issue.
Volume buttons are notorious on this phone. I have not known or read about someone fixing them. You can get around the problem for the most part by using software to control the volume, using roms that will restart to recovery or boot loader, and the occasional use of ADB commands, but some bootloop situations require the hardware to work.
Good luck with your project and let us know how it works out.
Not just a pretty Pickle.
I'm thinking of buying the whole LCD as a unit, but that is why I'm asking that maybe somebody could tell me if it's the LCD or other hardware.
The volume button it's together with the upper camera board and I guess it has to be replaced together.
My sister just broke her moto x pure.
The display works, however the digitizer do not works correctly. Cannot post pictures because the wallpaper is containing private information and i cannot change it.
She cannot use the entire screen.
For example on the lockscreen, she cannot use the 8. And the other digits works very badly. So she cannot unlock her phone.
What should I replace (screen, digitizer...) and where should I find the replacement part ?
Thank for your help
You'll need to replace both the digitizer + display as they come together. If you are good at repairing phones, you can get the display from eBay or else send your phone to service center if you don't. I would suggest you to send it to the service center.
You could use a USB OTG cable to connect a mouse and thus regain control of the device in order to clear any sensitive information prior to having someone fix it. I have bought and fixed several Moto X pure edition phones with cracked screens for family members. Most of them did alright, but one phone had the screen replaced, then a cow stepped on it. Although it didn't crack, after a while parts of the screen stopped responding to touch. The screen I replaced it with has not been damaged at all, but parts of it have stopped responding to touch as well. Sometimes I wonder if these phones don't have a particularly weak and easily damaged screen. I sometimes get my replacement screens from GadgetFix. If you fix it yourself make absolutely sure that you get a screen+frame assembly. It's just a few dollars more, and totally worth it. And be careful when you transfer the speaker grill trim to the new screen that you don't press hard enough to crack the screen.
Thanks you, I think I will change the screen and the frame.

Is this what I should buy ?
The screen that you posted does not include the frame. I briefly looked on eBay; you might find one with the frame included for a few dollars less than gadget fix, but for simplicity I just linked this one. On the back side of the display you will notice the screw inserts. That is what you need to look for.

Thanks !
Could you point me to a tutorial or a video explaining how to change the screen
I believe that Ifixit has a whole teardown tutorial for this phone. If not just search YouTube for (phone model) screen replacement, watch it a time or two, and then pause it while you do each individual step. If the first video you watch doesn't explain things in an understandable manner just watch another one. It's been a while since I searched for one, but I think there are at least a few good ones.
Hey everyone,
It's been a while since I last posted on here, and in attempting to avoid a pessimistic undertone, the G7 Power is actually a really good phone: the battery really does last for ages (I charge it once every two days, and it has never been below 40%), and it is surprisingly loud (everywhere). I am a pretty casual user now, rarely playing games or other media, but I am impressed with the difference compared to upgrading from a Moto G4. Some apps which appear as though they were designed for more premium screens - logos, icons, widgets - definitely lose some fidelity around the edges and these can look a bit poor on the 720p screen, but I have become oblivious (or distracted from) a lot of the finer details already.
And now the question: where, and how, would I be able to repair a cracked screen?
It feels like a pretty silly question; but the screen has 'developed' a crack from the bottom-right corner of the new notch, to about 2cm underneath the power button.
I say develop, as the phone is always within eyesight or kept in a pocket. It has never been dropped onto a surface harder than a pillow, and the case/screen protectors are still yet to arrive. It has been in my possession for about 12 days, and it lasted for 6/7 of those. I still have no clue when or why the crack appeared.
The question is a combination of where/when/how, I have contacted Motorola Technical Support, and explained the situation leading up to the cracked screen. The response was (exactly): "we do not process repair of the screen, what we offer is replacement of the whole device", they also said that this service will cost a fee (shipping + device) depending on the IMEI information. A single crack on the screen resulting in the replacement of a whole device seems pretty excessive, and the support member did not acknowledge that it is a brand new phone, or that it is* under warranty.
This is the first cracked screen from all previous handsets, so I am not sure what to do: is there any way to avoid replacing the whole device? How does this effect any warranty? What if I/whomever repairs the device creates other issues? When would services and replacement parts become available? XDA always has a someone whom is knowledgeable in these areas, and it would be great to hear some helpful advice from the community on how to proceed,
Thanks all,
MrSpuddy
(Also - the phone was bought directly from the Lenovo website - and I was hopeful that the "one free screen replacement" still worked)

Please see the teardown video here: https://forums.androidcentral.com/m...-power-xt1955-disassembly-teardown-video.html
I repair a lot of phones as a hobby. And phone that are assembled front to back are hard as hell to fix. You have to remove pretty much everything to get to the screen. Contrast that with something like the Pixel phone where the screen is connected last. You just have to pry up the screen and unplug the cable. Fixing the screen on the Moto G7 may not be worth it.
My recommendation is to use your phone as long as you can and then buy a new one. Hopefully by then it will not be as expensive as it is now. I know, it is not much of a solution...

The solution provided by the company was just to buy a new phone; which was not very helpful at all. My collection of screen protectors arrived, and the one on the phone is a lot more robust than the original screen.
Thank you for providing the video.
These screens are very easy to replace... Multiple times...
I have the moto g7 and I have replaced the screen four times, and I'm getting another screen in the mail this weekend, because this *[email protected]_-HJN' SUCKS DONKEY WHATEVER. I like the phone, but for some reason, the screen doesn't like to stay in one piece. All you need is a hair dryer and a new screen. Amazon has them. But you have to watch out; there are counterfeits out there. Buy from two different vendors, and return the counterfeit. Here's how to tell: make sure the printing on the ribbon cable is the same as the one you're replacing. Make sure that the printing on the back plate is the same as the original. You won't know until you take the screen off, which replacement is legit. But it's just one connector and some glue. Way easy, or mail it to me and I'll fix it.
