Thanks for photos! My horisontal rows are at the same place as yours. Furthermore, this situation is very and very common, many people have rows at the same positions.

If it is not hard to remove the screen, we can replace them ourselves: my idea is to order new screen from China, it costs about 60 USD there (at AliExpress).

The bad thing is that the new screen can be also defective.

Please explain how you removed the grille at the bottom of the device.
[YotaPhone] keeeper:
it's simply glued, all you need is to get some pincers and pull carefully. You can follow this guide:

To your mind, is it possible to change only the display without replacing the glass? Now it is very easy to buy used phone with a broken rear glass, but the working e-inc display.
[YotaPhone] keeeper:
the epd screen is embedded in the plastic case below the glass, if I wanted to disassemble it I'd have to rip the poor thing apart
[YotaPhone] Rastignak:
Hello everyone,

Just to let you know that a recent french buyer (that's me) of an YD201 discovered after 3 days of use 3 lines out of order... the very same place...

I'm dealing with the seller efoxtienda.com to get a solution. I paid with Paypal in order to benefit from protection...

For now on, the lines are 1 pixel wide... so that's not a real matter... but I don't want to wait till it gets worse.

I will share the issue of the negociations.

Enjoy.
[YotaPhone] TheArt.:
I ordered one from GearBest (Y201) and I really hope that it is without hardware issues.
[YotaPhone] George white:
Dont forget to make a video of unpacking...
[YotaPhone] keeeper:
Because of the EPD, my phone is getting worse:

-it very rarely refreshes itself, and if it does then looks like above..

-the battery drain is terrible (50% loss in about 2 hours, mostly screen off)

-the heat of the previously mentioned capacitors gets scary

-phone reboots itself once a while

I've decided to disconnect the EPD (almost) completely and see what happens:

Digitizer (1) and EPD (2) are disconnected now, but there's some link at (3) and can't be unplugged. Not sure what it does.

Beside physical changes, I used Titanium Backup to freeze all EPD apps I've found (altogether was 39 apps) - especially Organizer and Counters were stopping themselves just after the reboot, very annoying. Will give you info about how it works in several days, as for now the only difference is around 2sec delay* between pressing the power button and turning on/off the screen.

PS. The good news is that, now I don't care about destroying the EPD, so perhaps after new year will have some fun with capacitor replacement :)

(*)EDIT: It's good now, just don't freeze Back Screen Manager app
[YotaPhone] George white:
I do not understand about (3)...

How can I change the screen if (3) can not be unplugged?

PS How much time has passed since the first row appeared?
[YotaPhone] keeeper:
Sorry, my bad - I took another look at the Y2 disassembly video - (3) can be disconnected, although it looks like soldered to the mainboard. Didn't try.

I bought my phone in the middle of September, first line appeared few days after.
[YotaPhone] TheArt.:
Sure, but why?
[YotaPhone] George white:
Sometimes the devices, which are sent from China, are already defective. There are several such cases..
[YotaPhone] George white:
To your mind, is it possible to stick the grille back to the same glue?
[YotaPhone] keeeper:
yes, if you do it carefully then after sticking it back you'll see no difference
[YotaPhone] George white:
Third stripe appeared about an hour ago
[YotaPhone] George white:
Hi guys!

I want to describe how I solved my problem with a defective EPD-screen.

First, I bought a used smartphone with broken front screen, but the EPD in perfect condition (about 1.5 month in use).

Then I changed the EPD screens myself. I put the normal screen to my device, and put my defective screen to broken device.

Finally, I sold the donor smartphone for parts.

In this case, new EPD-screen cost me about $ 25.
[YotaPhone] Tippfehler:
Is this the same hardware problem?
[YotaPhone] George white:
Yeah, it is!
[YotaPhone] sonof:
I also have the same problem and in the exact same part of the screen as in the picute in post #26. Mine is two months old YD206.

Looks like post #9 has it also in the same part of the screen so it seems to be a design/manufacturing problem.
[YotaPhone] Tippfehler:
Ghosting? The lines have changed, new picture.

As expected, this does not help.
[YotaPhone] Tippfehler:
Last Picture, now it´s on the way back to yota devices.
[YotaPhone] vc926:
quite satisfied with eInk and yota apps, but a dead row arrived just 24 hours on hand :eek:
[YotaPhone] Tippfehler:
Is there a difference between YD206 and YD201? (e-ink display)
[YotaPhone] Leeeborg:
Yes, LTE frequencies.

201 - B3/B7/B20

206 - B1/B3
[YotaPhone] Tippfehler:
Thanks, I know, but I mean: Is there a difference with the e-ink display?

If I look at the ebay auctions with broken yotaphones, I think, all yotaphone 2 have the same risk for a defective e-ink display.
[YotaPhone] Leeeborg:
I bought both YD201 and YD206. The e-ink screen is the same.

There was only one difference - YD206 has older version of android (4). It means there was older version of applications for e-ink too . For example the font in ebook reader was not good antialiased as in android 5.

But you can flash phone with newer version (5.0) by using official tool. I did it and it works well ;)
[YotaPhone] Tippfehler:
I bought also two YD206 and one YD201 until now and have installed 6.0 and 5.0 on all of them and changed the radio firmware to cn, if needed. I know the differences, but maybe one version has an e-ink display from a different manufactorer or maybe a different voltage, maybe the motherboard is a little bit different.

(Earlier I have had same HTC smartphones with different displays (Acer or Sharp).
[YotaPhone] TheArt.:
Really the motherboard is different between 201 and 206? I always thought they had exactly the same HW. Can you prove that?
[YotaPhone] Tippfehler:
Different LTE Bands, same hardware?
[YotaPhone] TheArt.:
LTE bands are integrated into the SoC, and can be activated and deactivated with special software. As the SoC is the same, some people suppose that the two models are identical.
[YotaPhone] keeeper:
So finally I found the matching capacitors, looking only at its size due to lack of information:

[IMG="3.2mm x 1.6mm - got 100uF, 6.3V"]https://dl.dropboxusercontent.com/u/62881295/Temp/size.JPG[/IMG]

Changed old to the new one (soldering wasn't smooth - it's so tiny!)..

[IMG="Maybe not so neat but should work.."]https://dl.dropboxusercontent.com/u/62881295/Temp/after.JPG[/IMG]

And in that point I stop, as I did a HUGE mistake earlier. Remember this photo?

Turned out (3) IS somehow attached to the mainboard. Thought it was just glue, pulled a little bit too hard and broke the cable..

That makes me thinking even changing the EPD screen to the very new may be impossible. For your consideration.

PS. firstly hoped it's not essential for the EPD funcionality, but looks like without it the second screen isn't discovered by the phone. :(
[YotaPhone] spinecki:
I think you're right with the temperature damaging the screen. I was contstantly flashing firmware, from one to another and device got pretty hot. After that some dead lines appeared.
[YotaPhone] zertyz:
Tomorrow I'll put my hands on my long awaited yotaphone 2 ordered from gearbest. I was just reading the manual when I found: "Temperatures lower than 0°C or higher than 50°C affect the performance of the EPD. Do not use your device in high or low temperatures."

Did someone observed this relationship?

... and did you try to do a hardware reset to see if it is recoverable? Hardware resets are accomplished by removing the electric source and giving time (a couple of minutes, maybe) for components to discharge and loose their state information. Disconnecting the battery is one way of doing this; letting the battery drain until the phone dies and waiting one or two days before charging may be another. Although, for what I've read here, I guess nobody who disconnected the battery had the EPD back... right?
[YotaPhone] JabbaEPD:
Hi everyone,

I'm now on a second YD201, the first one was returned because of blank row on the middle of the EPD screen that appeared after one month of use. Now the second one is also showing a blank row with only one week of use, it also gets a lot warmer than the first one (apparently when WIFI is enabled). Upgrading to RU 1.134 helped a little bit with the heat since WIFI radio and other stuffed is now turned off when not in use. But as soon as one starts to browse the web, etc. the excessive heat and battery drain is imediately noticeable.

Don't know what to do, I use the EPD screen alot! I hate to have to return this one also..

Cheers,
[YotaPhone] Hiratechi:
Where to buy?

i want to buy this EPD but i can't find it, can you tell me the link at aliexpress?

thank you

https://pt.aliexpress.com/item/100-...lgo_pvid=3fc53aaf-e1fd-44aa-9c6a-4534e6103658

here, nearly the price of a new one sadly...

Any updates on this? My screen is showing an horizontal white row and I have it for one week. I was using it normally then it just appeared. Did anyone tried fix the capacitors?
[YotaPhone] zuoyejing:
I have also broken EPD screen by too much of rewriting firmwares and backups.

I didn't realize it's extremely fragile by heating.

Just 3 weeks after the smartphone arrived... very sad.

Now I am going to try to purchase EPD assembly parts.

It seems to be selling around 300 CNY (44 USD) excluding shipping fee.
[YotaPhone] wilver:
where? Can you please post the link?
[YotaPhone] zuoyejing:
This shop deal with EPD screen assembly parts.

ttps://world.taobao.com/item/527841676256.htm

"黑白墨水屏总成（白色）" means "Monochrome EPD assembly (White)": 290 CNY (42.09 USD)

"黑白墨水屏总成（黑色）" means "Monochrome EPD assembly (Black)": 245 CNY (35.56 USD)

But it's relatively hard to purchase directly if you don't understand Chinese.

I also don't confirm they can ship to out of China or not yet.

Wait for me, I will contact the seller.
[YotaPhone] zuoyejing:
Unfortunately, the seller won't ship to foreign country.

So I consider to buy it through proxy purchase trader.

Additional cost maybe 90 CNY (13.06 USD) to my country, Japan.

If there are some "taobao proxy trading service" in your country, I recommend you contact them.

If there's no trader around there and you want to buy the screen seriously, I can buy yours, after then I send to you.

Delivery charge (Under 500g, International e packet service from Japan to the other country, not EMS) may be....

to Asia: 980 JPY (8.95 USD),

to North/Middle America, Europe, Oceania: 1,235 JPY (11.28 USD),

to South America and entire Africa: 1,525 JPY (13.93 USD)

...Umm...there's just a slight cost advantage than AliExpress...but considering the other risks, not good way...
[YotaPhone] Pak07:
Several days ago the same ago happened to my 206, after only 1 month using it. It is going to be fun to deal with the chinese store.
[YotaPhone] Tippfehler:
On my new YD201 are also three gray lines in the status row and one short grey line appeared. The lines and the area are different from the others.

---Edit 7.5.17---

Unfortunately after three weeks, more lines and rows are appeared.

My Yotaphone is since weeks in Moscow and cannot pass the border (Uncontrollable Clearance Delay). I hope, I will see it again.
[YotaPhone] zuoyejing:
Hey you guys,

66 USD EPD screen (black) appeared on AliExpress.

According to my survey, no shop has white one.
[YotaPhone] Estrada88:
Sorry for my english, but I have one white line, it is on the edge of the screen (it is fully usable) and I would like to know if once starts more lines will appear, because if not I will keep the phone, but the paypal's protection is running out and if it is more than probable that more lines will appear I will open dispute and I will start to find a new phone.
[YotaPhone] sonof:
More lines will probably start to appear to your phone. You should opt for buyer's protection.

Do you people think using wireless charging increases the likelihood of getting white lines? Wireless charging generates more heat.
[YotaPhone] veggiedelicious:
What I read in this thread and in other threads is that it seems the white Yotaphone 2 has more problems with the default E-ink screen than the black YotaPhone 2. This might be because of a default assembly line in the source .. The chinese plant where the YotaPhone 2 is made. Default materials.
[YotaPhone] Tippfehler:
I have four black Yotaphones and two of them have grey lines.
[YotaPhone] Estrada88:
Well, when I was ready to send it back, the line just dissppeared. I contacted to yota official service and they told me that I could try to discharged fully the phone and let it 24h. It could be an agressive ghosting. I did it and nothing happened, but 48h later I took the phone and was gone. I attach a picture of the line.

[YotaPhone] zuoyejing:
I have bought EPD assembly through TAOBAO agent, and succeeded to replace by myself.

And dead lines gone completely.

So, this issue is definitely caused by hardware failure.

Sorry, above my website is written in Japanese.
[YotaPhone] kbal:
I also got a dead line :(
[YotaPhone] glasseffects:
This dreaded condition developed on my screen as well, so it seems like construction issue. It's a shame that a device that sold for gold once is inherently flawed. Time to bid farewell to Yotaphone.
[YotaPhone] kbal:
NOw I have 2 dead lines :,(
[YotaPhone] fcrvincent:
Here too a third of an horizontal line stuck to white at the top of the Y206 EPD screen.

It developed today when the phone was not overheating.

This happened after just 2 weeks of use.

This is a warranty replacement phone from Gearbest after the first had a dead battery after just four months of light use.

Obviously the phone has some design issue.

A pity as the dual screen concept was really great.
[YotaPhone] Sukalya:
I noticed first 1 white line when I accidentaly dropped it, the tomorrow 2 new ones showed up...now I got 6 of them xD

4 of them not really that noticable only when you look at them really close, rest 2 lines really catching eyes...****

I also noticed when phone overheats it triggers new white line to show up wtf
[YotaPhone] Justin_Deane:
Blank row

Hello. I've got the same issue. A horizontal dead grey line dividing my e ink screen in half.??. Is it a loose cable? What's the actual cause? Can I fix this myself. No service centre here.

---------- Post added at 12:26 PM ---------- Previous post was at 12:21 PM ----------

You may need to open up and ensure the screen cable is in properly. But I need someone to confirm that this is worthwhile.
[YotaPhone] darkraver9578:

I sent mine to coolicool.com service to China. They wrote me that this is "user damage" (of course, coolicool and efox shop are crappy stores).
[YotaPhone] songzi:
My Yotaphone 2 e-ink display has the same issue - there is a white horizontal line across the middle of the screen. I am not sure whether it is worth to purchase new parts to replace the display. I have three yotaphone 2 sets purchased in China. The other two are still boxed. If the phones will all have similar issue in future, I may consider to sell the other two phones.
[YotaPhone] NF404:
Hey, 2 weeks from now, a white row appeared on my e-ink screen. However I noticed that when my phone is off, this same row is not white but black! Does this mean it is not a dead row (since it can be black)? So maybe I can repair it?
[YotaPhone] George white:
Greetings

If you post some photos with the phone off and on, then we can judge what happend with it
[YotaPhone] NF404:

[YotaPhone] George white:
Sorry, but I am going to make you sad - your stripe is a standart yotaphone's dead row.

It can't be removed, but it can get worse. The only way of healing is to change the screen.

I have such a one at my YP2 since summer 2020, it doesn't disturb me much.
[YotaPhone] NF404:
Thank you for your confirmation... I was expecting this answer anyway. It does not disturb me neither, so I'll it like that and hope it does not get worse.

[Tilt, TyTN II, MDA Vario III General] apple_power:
Hello there everyone,

I have had my v1615 since the 15th of october, I rang up my business team to unlock my handset. They said no problem 2-3 days, so a week passes and I ring them up this afternoon. I go through the spiel and the lady says well sir, we have the spreadsheet and your IMEI is not on it. Which either means you have given us the wrong IMEI or your phone is unlocked already, or you have an import.

She asked polity have you tried a different sim card sir? I said off course not, so we go through repeating IMEI's and I said ok, I will try with a different sim card and lo behold. IT really is UNLOCKED.

I am using it with my t mobile business tariff. I can not believe it am I just lucky or has anyone else tried it?
[Tilt, TyTN II, MDA Vario III General] mb:
Mine came unlocked as well - it was one of the first things I tried! Happy days indeed
[Tilt, TyTN II, MDA Vario III General] Deleted member 470721:
What the hell?? Mine too!

I called Vodafone a few days ago to get this thing unlocked because i plan on using it abroad and gave the lady my IMEI and everything and after the:

"What model phone is it?"

-"It's the vodafone 1615."

"Yes but what brand is it?"

-"err vodafone"

"no sir what BRAND is it?"

-"its brand is vodafone. It's the 1615. By vodafone."

"yes but what BRAAAND is it?? Is it a Palm? A Motorola? A nokia? What does it say on the box???"

"it says VODAFONE 1615! It's a vodafone! V-O-D-A-F-O-N-E!"

...discussion i told her HTC made it but its doesnt say that on the box i just know that. Then she muttered something about 12 days(?) hours(?) Something anyway, that they'll email me with the code. They havent.

Anyway just now i came across by accident on this thread and thought, what the hell cant hurt to try. So i put my Cypriot sim and it worked fine! Calls and everything. How cool is that? I like vodafone a bit better right now...
[OnePlus 3 Questions & Answers] njhardc0re:
I noticed that when charging the phone the only color that it uses is blue. I have it set to yellow when charging but it never works. Anyone else have that issue?
[OnePlus 3 Questions & Answers] Azbulldog:
I have noticed this as well, and it may be linked to dash charging. Nowhere in the settings is a blue LED set.
[OnePlus 3 Questions & Answers] Rauttis:
It means the phone is dash charging. There's no way to change the color in the settings, seems like an oversight.
[OnePlus 3 Questions & Answers] njhardc0re:
Yes, I noticed on a regular charger it will use the correct color. Dash seems to be only blue.
