Some days ago my Yota started to restart on its own. It happens once a day usually.
The biggest problem i noticed is that on the e ink screen now a white row is present and does not refresh anytime.

Firmware is 1.87a eu, original, not rooted. Anyone has experienced it? I hope there is a fix cause I do not have time to go to a support center and leave phone there to get fixed.

Cheers

I bought my Yota about 2 weeks ago and firstly epd was completely fine then I noticed horizontal blank stripe few pixels wide that does not refresh. Then another one appeared, this time vertical and only 1px wide. Today I got third (next to the 2nd, also vertical).

I don't know the origin of those, as had 2 ebook readers before and never experienced such a thing. Wonder if it's a software issue or some failure with the device. Tried to Google it but it looks like it's not a common problem. Thinking of flashing the 1.99 rom - maybe it will help.

I am sure that this is a hardware problem. I have my third Yotaphone now (because I love the concept). One I got replaced because of the EPD showed some lines. Another one has a fine vertical line, another one a fine horizontal. They are on different software releases. one on Middle East, one on European SW. No difference. The places are very different. So, a hardware issue.

Hi! Yesterday I have got the same thing - dead horizontal stripe appeared on the e-ink screen. Please, give an answer, based on your experience - what will happen with the screen soon? Can the screen work for a long time in this condition, or is this a sigh of a soon total failure? Thanx 4 answer.

Based on my experience it should go on working as usual, but the stripe won't disappear. Speaking about it with a friend of mine, he told me that this is a common problem with all e-ink displays. So if it is still on warranty my suggestion is to send it to be fixed. If it is not, do not panic, should be fine, at least I hope. Mine goes on without any problem , exception made for the stripe.

Won't be fine, sorry to say that. There will be more and more lines until the screen will start to behave weird in total (inversion of colors, no refresh, not working yota mirror..). I'm 99% sure that's overheating problem and plan to open my Y2 to find out soon.

Had 3 other devices with eink screen before (2 nooks, 1 Motorola phone) and haven't seen this issue yet.

Better use your warranty before it is too late.

I purchased my Yotaphone 2 in June 2015, in August 2016 a horizontal line appeared about 1cm down from the top of the screen, then about a week ago a short vertical line appeared, just off centre going from the top of the screen down about 2cm. I asked yotaphone and they said to take it to their service centre but this isn't very convenient for me. I am hopeful it won't get worse! Interesting to see other's experiences, it is clearly a common problem!

<<edit>> The two dead lines are 1 pixel wide, the horizontal one is light grey in colour, the vertical one is white.

Three days passed, second line is dead.
It's about 1 mm from first one.
No warranty, unfortunately... Screen replacement costs abous 120 USD. I'm sad

Ok, so I opened my Yotaphone to find out what's causing the dead rows:

Problem
OPENED
EPD
DIGITIZER
EPD INTERFACE
CAPACITORS

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.

it's simply glued, all you need is to get some pincers and pull carefully. You can follow this guide:
