MMX Yu Yureka Review

Hi there Everyone!
This is my Yureka Review, I got this Phone on 24th, Without Wasting Time...
Let's hit it
Please Correct me If I'm Wrong
1. Camera- So, This Phone's got A 13 MP back camera and 5MP front Camera...
The 13MP camera is great for Low Light Photos and Daylight pics are Awesome...
The CM camera App makes photos even Good...
The Back Camera shoots great Photos and Focus Makes it More Good...
The Front Cam is Awesome for taking Selfies with Camera Angle 88°... Really Great... I tell You!
2. Talking about the OS, It's got Cyanogen OS 11... Those who've used CyanogenMod may find it less customizable but those who haven't, Surely You'll love to Modify it...
3.Hardware
It's hardware is pretty good in ₹9K, I was getting the AnTuTu Benchmark Score 31291
I tell you, It's Really Great!!
4. Build Quality- The Phone is Nicely Made, With an LED Notifier at Top...
Volume Buttons on Left and Power Button at nearly Mid-Right
Jack at Top and Power at Bottom
If you get to Hold it, You'll Say- Man! It's so Light!
Yes!The first time I took it up, I thought the battery was not there put up inside but I was wrong, Even though the battery was there, It was light as air...
Well, Not actually...
It's Slim As Well, Quite Slim
I'm sure he was on workout and Dieting...
The back feels like some Carpet is put up... So comfortable and Strong Grip...
5. Bugs-
Now the Cons.
1. Phone gets heated up quick even if you're Running Facebook... But What I mean with Heating is, it gets lil warm at the top back... Nothing Much...
2. MY QUIZ UP RESTARTS OFTEN WHILE PLAYING...
3.As reported by our Forum Member Ajith, the charging get stuck at 99% and some Frames get missed even on Temple Run
But these Bugs are mostly, All most, Software bugs; Which Cyanogen has Promised to Kick 'em Over in Software Updates Coming in Feb...
So if you're looking to buy a phone Under ₹15000 for Now,
Surely, No doubt, Go for Yu Yureka...
But It's not that easy To get it...
Thanks For reading...

Battery drain (as expected) issue
camera issue (Some facing)
WIFI SUCKING battery
HEATING ISSUE (WATER HEATER)
Proximity issue While making calls

There is an issue with the proximity sensor, its not working some times.
Heating issue is present but it depends up on the apps. playing games like NFS is causing more heat than any normal games.
Rear cam is damn good no issues about that. never faced WIFI and random reboot issues

Yes, You might be having them but you see, They are only Software Bugs... Don't worry Man! We have software Updates Support...

There are many software bugs.

I think Cyanogen will fix all the bugs in future updates. No software is perfect out of the box! Let's see how cyanogen deals with the promises along with YU.

Reboot issue
I own Yureka & my phone restarted once or twice when I play game, especially Clash of Clans.
I guess this is the CPU heat issue, still checking. I have underclocked CPU to check if phone reboots randomly or not.
Will post results. Meanwhile if anyone have solution, I would be happy.
GK.

Hi,
So with these kind of issues like heating/reboot, etc.... you mean to say that we have some kind of solutions, and not to bother though every phone faces the same issues, if am i correct.
And, we can go and grab this phone though we get it below 10k which has good features where we dont sunch phone.
I'm impressed with 2GB-RAM mostly.

Hi. Thank you for reply.
Finally I have found solution.
I underclocked CPU to min 400 max 800 MHZ and set IO scheduler to noop (that is FIFO with very less CPU cycles)
I have found considerable less heat issue now without any lagging with COC. Also now battery lasts much longer than earlier. I am very happy. Cheers !

You could use this as a reference
Hey! For those wondering how the camera on the Yureka really is, here's a screencast of the same so that you get a feel of what it really is! youtu.be/oSkgd8jwCKs
I'm not allowed to post links so please add http:/ in front of the above address to view.
Else search for screen cast recordings on youtube of each phone. You'll get a feel of how the camera really is

Burn-in: does anyone have it yet? How paranoid should we be?

Has anyone noticed any burn-in problems yet? I've seen reports of the problem for some other watches (LG), but so far nothing specific here for the Huawei.
It's so far so good for me, but I've been extremely nervous about this issue. I avoid faces with things like thick tic marks or logos in ambient mode. I know about Wear's built-in "protection," but I don't have a lot of confidence in it. Am I being unreasonable?

I had the GWR and didn't have any issues with that at all. That said I turn the screen off at night during charging so maybe that helps. I'll keep an eye on the Huawei, but I'm hopeful that it will be fine.

I had the GWR for almost a year too. Always used watchfaces that are 'always on' (so no dimmed mode without background) and always had the charging animation on by night. Never experienced any burn-in.

I just powered mine on for the first time last night. I played with it for a few hours, then put it in the charger for the night and this morning it has burn-in!! How could it happen so fast??

The outline of the watch face. If I change the watchface and swipe left, you can see the outline of the other face as the background instead of white.

hell no, wtf!!
it is very bad, sorry for that, were you using this watchface long time ago? what is the watch face look like in ambient mode? maybe the watch got really hot, and screen on while charging. i started to worry about the screen quality of this watch.
Edit:
i have seen this is your first day, i think maybe a faulty screen

Yeah, I'm wondering if your watch just froze in full display mode overnight.

That deserves an RMA and you deserve a new replacement watch.
I sometimes get lag on mine, im not sure if it's actual lag or whether im doing something wrong but as someone mentioned if the watch went full brightness and is charging then the heat might have done it?

I returned it yesterday to best buy. Lucky me though. . they had cyber Monday deals and it was on sale for $50 less! !

I noticed that when the minute hands on mine move (ie every minute) that the whole screen kind of does a refresh. I'm using a custom watch face called InstaWeather, and in the settings there's an option to help with screen burn. I wonder if this is it? So every minute, every pixel would have been off/on or on/off?

yes, this is an android wear burn in protection buy moving a few pixels in all directions, works very good if you don't have large objects in the ambient mode, and won't help much if you have.

In my opinion, yes, you are being overly worried. First the technologies itself has improved and we see less burn-in even when we set screens on to test such a thing. Second, the ability to move(write) a watch face or screen is not some huge leap, in fact it's really super easy to add to an OS to simply move the screen pin outs when in any long display mode. Beyond all that, app makers, watch face builders, now have the old data and make sure they write to avoid any long same display visual mode.
Easy to add to an app, when write same display, write 2 pixels, change.
Then after all that we have face on mode and ambient mode, which in my daily use changes my watch face enough that I would never get burn in. Agree that I am a heavy user of the watch, I tend to have to change twice a day. Perhaps someone that used the watch much less would have more of a concern?

I have the same problem

Wrong. You must not understand what screen burn in is. No new technology has come out that will stop screen burn in. The software that moves the pixels over only works if the object is 1 pixel wide other wise it doesn't work screen burn in will still happen. And they do not have it where the same pixels won't be used otherwise in ambient mode it would jump around not wiggle.

Reset the watch. It may not be burn in. I saw a bug like this from using too high Def of an image on a watch face. It got stuck in the cache even after I changed watch faces. I reset the watch and haven't had any issues since

Fare enough, just my opinion, & you have yours. Too bad you had to start by saying wrong.
Samsung has made changes to light output and color to reduce burn in, and we all know there is some type of display movement now to also reduce burn in, so it's odd you claim there has been nothing.
Anywho, I don't get burn in so yea, maybe with your attitude if you do, you deserve it?

I'm not going to start it by saying you're right, am I? Samsung didn't make changes to anything in light output the only thing that's changed is adaptive screen color which is meant to adapt the screen contrast to show what's on screen in the best possible colors. There is no new technology that will stop burn in. You must not have understood me. The image wiggle is a software attempt to stop screen burn in from happening but it won't stop it just slow it down. Screen burn in will continue to be a thing until the panels we use change technology. I didn't say that nothing has been made to prevent it.
And if you sense attitude in a straightforward response that's on you. I'll let karma deal with that comment. I personally don't get screen burn in and I've had a SAMOLED device since the Samsung Epic. I just understand how to prevent it. But just because I've never had it I won't tell people that they're overly concerned about screen burn in.

MTCB Joying Display flickering and "burned in" picture

Hey there,
I have some issues with the MTCB. Someone had these before?
First problem which is already quite annoying is that pictures are kind of burned in and still show shadows on the other screen
Second problem which is even more bad is that the display flickers. This is more or less obvious in different scenes.
When looking closely it seems like there is a grid (coming and going in the same frequence like the music is playing?). The attached video shows it.
Especially with white background the flickering gets very bad.
Don't know if this could be related to the Malaysk Firmware I use. Or is is it a hardware issue?
Also contacted the support. Let's see what they say...

Sounds like a screen issue to me, have you checked the ribbon connector hasnt come slightly undone ?

This is commom in these units.
It's worst when it's hot.
I kinda fixed mine opening it and adjusting some kind of screw near the screen. You turn it and screen gets darker, you need to find a point between too dark and flickering. But when I park my car at the sun, and it gets hot inside, screen get bright again, so flickering and persistent images.

And here is a video about it.

It's commom. That's why Joying even put a video online to show how to fix it.
I believe that when they produce the unit, it's now well tuned up, or it's cold in the factory and they don't realize, so when someone who lives in a hot weather area install it, the problem appears.
It's a bad hardware design, they use analog potentiometer, they should use some digital and automatic one to regulate screen frequency.

Well, Like I said, I ve not heard much about it in the 3 years I ve been following the threads on here, but I do remember Joyous having problems with their screens and 5.1.1 - they couldnt get 5.1.1 to work on their 4.4.4 RK3188 units unless the screen was changed !! Sounds like its more a problem with Joyous units.

I agree there's not many complaints about this problem here, that's why I believe that may be some "quality check" sloppiness. It's very simple to solve anyway.
But all units seems to use analog potentiometer, so, bad design. There's nothing to do with Joying only and the fact they changed screen to update to 5.1.1.
And most users in this forum don't live in hot weather areas. In my case, Brazil, is hot must time of the year, above 34 C degrees (93 F), in the shade.

Youre envious of 4 deg C ?! I get 34 deg C is a bit hot, but 4 is a bit cold !
Half way between 4 and 34 @ 19 deg C would be perfect

I looked at the map and St. Helena is a little to the south, a direct flight seems a better option.
But feel welcome if you want to come to Brazil someday.
It's a bit messy but it's a good country. I'm not going to take you to meet any favela, by the way. Don't know why tourists are so eager to go in one, it's very dangerous, and I don't think they represent Brazil that much, so many different beatiful places to go.

Hey there, thanks but the video is not working.
I did not open the unit yet to check if the screw will improve. But I will test soon when I find some time.
By the way it's around 0°C here. So not very warm
Attached is another video. The flickering of the right white picture is actually visible. It's not a flickering of the camera.

Just open the unit and fix it, very easy.

Took some time until I tried the fix. But the screw fixed it.
Carjoy recommended a power filter, but since the screw fixed it i prefer this...
The screen is now slightly darker. But I like the crisp image and better saturation of the colors (and of course no flicker).
Thanks!

(survey) different shade on screen upper part than lower

hello friends,
I am having weird issue from yesterday.
my phone was too hot while charging and i was gaming.
I felt that colors are shifted too much on upper part where device heat.
then i tested with screen tester app, all colors were looking fine, but when dark gray comes, there was warm shade on upper part and cool shade on lower part.
I thought this will recover after device cool down, but now 1 day passed, 90% screen recovered but 10% still remain different.
I am going to RMA this and did not expected this from oneplus, oneplus 7 still far better in display department..
.
you guys, please test this as I mentioned above and reply here.

tested 2 hours fortnite - epic settings with charger.
nothing happens
maybe cool down the 10% with some ice? but be carefull - maybe a "frostshock" recover the damaged displaypart.
if not, rma.

Yeah I have a little bit of that as well. It comes and goes on mine. It was much worse when I first got the phone. I was checking off the bat because I had the same (but much much worse) on the pixel 4.

Many MANY people have the same issue, enable DC Dimming in the OnePlus Laboratory to fix this

I decided to return my handset to retailer.
Great device, the smoothest i've ever used with huge potential for future development, but this panel is bit disappointing. I mean in normal light conditions it's so pretty you don't miss qhd at all. Once you step into dark room you can forget about dark theming.

It does fix the issue but then the contrast sucks. I just decided to deal with it. Hopefully it's fixed in a future update because overall I love this phone.

I am afraid it's hw issue.

Great device, the smoothest i've ever used with huge potential for future development, but this panel is bit disappointing. I mean in normal light conditions it's so pretty you don't miss qhd at all. Once you step into dark room you can forget about dark theming.

It does fix the issue but then the contrast sucks. I just decided to deal with it. Hopefully it's fixed in a future update because overall I love this phone.

Does anyone of you try RMA ?
Maybe they have updated panels from oem if this issue is too widespread.
Had same experience with poco with touchpanel. 1st novatek touch panels were worse in touch response, then they replaced it with focaltek touch panels for newer batches.

Yeah maybe they should but mine is barely noticeable. If yours bugs you then return it for sure but mine is barely noticeable.

Question Possible screen dimming / heat issue ?

Hello everyone,
I have seen tech youtubers test the F3 and some mention that it will dimm the display quite a lot when gaming. (also another one did 4k video shooting for extended time and seen the same thing)
Do you think this is because the SD870 really "could" have an heat issue in the F3 and the software is protecting the AMOLED from damage due to overheating?
However I am still looking forward to receive mine, I just want to utilize the bright display at least during normal usage

Not sure what happens, I'm seeing the same stuff on diferent video reviews of Poco F3, the thing is, Poco X3 or Redmi K40 Pro usually go even beyond 10+ºC higher and do not suffer of such dimming issue. I'm guessing it's something software related.

Yes agreed, the SD888 devices get hotter and do not show this behavior.
Let's pray it's a software issue.
Could also be that the E4 Samsung panels really do need to derate because of their really high brightness. Even a 50% reduction would be as bright as my F1's screen at max. brightness

I am reading in local Malaysian forums they talk about comments in Xiaomi forum for k40 having such issue. I don't understand mandarin I am based on what they said its an issue with K40. Let's hope software upgrade could fix this issue.

Saw the same problems in some reviews yet a member of this forum who already has it had some issues with haptic feedback others have battery problems. I think I will buy another phone

Well quality problems exist everywhere. Check out the S21 Ultra forum, there big discussions about poor camera quality are ongoing.

Yeah don't get me wrong, only having a slightly noisy haptic feedback motor is not a bad result. When I bought my Oneplus 3 back in the day, the USB-C port was slightly offset, so the cable wouldn't fit snugly and dash charging wouldn't work. I've reported my problem with the haptic feedback motor on another forum and people seem to agree it is slightly noisy, but other than that the phone works like a charm for me (so far).

@Kom_zo That is reassuring to hear, glad you enjoy it
Maybe this was Xiaomi's design intent all along to have a more "audible" motor.
I will check it out once I have it here.
Did you experience any high heat and unintended dimming so far?

I have not had the chance to use my phone intensively yet, just some light browsing and Youtube/Netflix. I have however just made a video of the haptic feedback sound and I can tell you that this is not by design (the popping noise is coming from the phone, not the recording)

@Kom_zo Thanks for sharing!
Agreed, it definitely sounds not normal - somehow like a hollow "clicking".
Is it bearable or will you return it?

I have haptic feedback turned off by default, but my phone will vibrate for alarms/notifications and calls. As of right now it might just sound broken, but it is a moving part that could cause more damage to the internals of the device. I will try to swap it for a white model in a few days, but I think I will return it either way.

I agree with the statement from the Malaysian guys, it makes sense.
However there is a video from the same youtuber which shows Black Shark 4 vs F3 and the BS4 doesn't dimm the display.
Though I don't know which brand/type of amoled the BS4 uses.
Edit: Found it, watch from minute 2 onwards:

Is there any green tint with low brightness?

Shouldn't happen, since the F3 uses PWM for the amoled screen which eliminates color shift at low brightnesses.

This problem happen too when you off auto brightness ?

I think the tech youtube has set it to manual max. brightness.
I can only assume it will limit brightness at high temps regardless if you are on auto or manual.

I might get bashed for this but you can underclock and undervolt the GPU with KonaBess: https://github.com/xzr467706992/KonaBess
It's worth a shot if you don't game a lot, it'll likely not overheat causing the screen to dim as much.
I still feel the screen dimming will be reduced with the upcoming MIUI 12.5 update for the F3.

POCO said on a live stream that they are working on the dimming problem.
