Bad picture quality on Samsung A50 - Samsung Galaxy A50 Questions & Answers

I have a problem on the lockscreen on my A50 the screen quality is bad it seems like the bitrate it lowered and everything where there is some gradient is choppy. This only happens on the lockscreen though there are no problems when the phone is unlocked.

no problems here on all previous SW versions , latest is December.

[Q] Speakers not working on DHD

Hello there,
Since a few weeks ago my speakers stopped working, and unless I plug in the earpiece I can't listen to videos, music, or even calls. I tried tons of different ROMS and the problem persists. In some ROMS the notification displaying that my earpiece is plugged in shows up, when they are not.
Any solution to this? Thanks!
Hey
Is there water damage to the phone? Any drops, knocks or such? Have to cleaned the grill?

Had the same problem last year, did some research on the net and found out that i onky had to give the back a hard push which fixed my problem

Ok, this is weird.
I've been really testing and paying attention to the problem, and the speakers actually kinda work. When I raise the volume, I can hear the beeps, also notification sound is working. WHat it doesn't work is the media volume (unless I use earpiece): videos, music, games etc
And also I cant hear the incoming calls and the people calling, unless I plug the earpiece or I put it on speaker mode.
I don't seem to find any solution, I hope somebody can help me
I have exactly the same frustrating problem. I can only speak with speaker on or with earbuds.

strange dotted line

i do have a strange dotted line at the bottom of my screen, which seems to get larger slowly.
The dotted line is shown when the device is turned on/off.
It's not in the glass, but below the glass.
I wonder if anyone has seen this before.
i tried to make an image of it.
Ralph
I have it too, not sure what caused it though!
No issue here.
The touchscreen is lifting from the tft, to which it's glued, causing air bubbles in the glue, IMO.
Me too although it doesn't bother me since it doesn't do anything to the viewing experience.

All, thank you for your replies.
I contacted Samsung support, and they informed me that it was no known issue on their devices.
If i want to have it repaired; i could sent it to Dynafix who does the repairs in my area, and they will check if it's a fabrication fault or an user fault.
I have sent the picuture to dynafix to see if they could say me something about it, though i am not sure if they will do this.
I will keep you updated.
Ralph
Ouch, dynafix..... You usually get your device back in a condition worse than when it was when sent in.

Me too
I also have those at various points along the bottom. They don't bother me enough to risk sending the tablet in for service.

Maybe answer is that; however,the seller said that these dots are originated from the people that scratch or something when i see these dots on the Screen of tablets at showroom of Samsung. But i think there is a problem. After a while i think all note 2014 will be like that. I examined all of them in different stores. Guess what. All of them has that issue.

I think you should bring your tablets to be fixed.
Also , i have a question for everyone who has that issue, are your galaxy notes 10.1 black or white ? I saw this issue only on black ones' screens. Are you using your tablets in fully brightness? Because i realized that it begins warming rapidly and more at bottom of the screen which is so close to the dotted place.

Brightness setting is in the middle. Yes I use it alot everyday for work. The screen is mostly always on and I charge it mid day in the office and still use it while charging. Sometimes the screen gets warm when being used and charged at the same time. Been using this tablet since November

Tnx for your replies,
I bought it in january. no dots observed yet. I also have black model. I dont use in charge. I use it portable way when it is not charging. I am so angry with samsung because of that issue. They had made really big mistake and they dont accept their faulty. They even dont try to fix this issue for next generations.
At first I was bothered by it.. but now not so much. Good thing the dots are on the bottom of the screen and you wont notice it when using the tablet. Yes still samsung should fix this issue

Mine is black.
I have used it while it was charging but not very often.
I purchased it new about 7 weeks ago.
I had the exact same issue with my first note I bought in November. Ended up returning it to the retailer about 6 weeks into use and buying a new one I've had for about 6 weeks so far as well. No issue on the 2nd one as far as I can tell right now but this seems like another common problem.
If these bubbles/dots are caused by the reasons i mentioned earlier, they align with the colored rim of the touchscreen, because the color layer increases thickness of the glass by some nanometers. Going towards the center of the screen, the gap narrows because of adhesive force bending the glass. This should prevent the bubbles/dots from wandering inwards. Otherwise there's a huge issue with the device, though mine is (still) fine.
I noticed these dots on my white note after I got it back from battery repair. Not sure if it was there but I have 3 clusters of bubbles now
Sent from my SCH-I545 using Tapatalk
since yesterday i've this strange line as well. It came out of nowhere. After reading this tread @yararli could be right about something. Normally I use my screen about 25% brightness. Yesterday I watched a episode at almost 100% brightness. So there could be a causality between the brightness en warming-up which result in this strange line. My tablet is black bought it around december.
Is there any news about returns? Will there repair this problem or give a new tablet?

Pixel c or galaxy tab s2

Hi,
I'm about to send back to amazon my brand new lenovo yoga tab 3 pro : it's cute, with premium feelings, has a great pico projector, but it is so laggy!
So I want the best android tablet.
For 500€, I can have the galaxy tab s2, 32gb with sdcard and LTE.
And i can have the beautiful Pixel C 32gb without the keyboard.
What do you think?

Yesterday I bought the Galaxy Tab S2. There was a great offer in Germany: the price was 459€ and you got a 100€ voucher and the Samsung book cover with keyboard for free (official price for this is 160€). So it's 359€ for Tablet and cover.
But if I had had the choice to get the Pixel C for the same price I would choose the Pixel C I think.

Pixel C of course, Tegra X1 vs Exynos 5433.
No contest, Tegra X1 is much much faster!
Comparison threads are against the rules.

The lack of hard buttons on the Pixel C alone is enough to justify going with the Pixel C, in my opinion. Samsung is so far behind with their hard buttons (back, home, recents) being embedded in the bezel. Android has a lovely interface and soft buttons just work better. Especially on a tablet where you will be using it in both portrait and landscape modes. Having an insanely fast SoC and the best build quality, bar none, is just icing on the cake.
I had the Tab S2 for just under a month and returned it. Same ole' same ole' Samsung. Lighter, faster etc... but really its just another Samsung.
So, I've read many things
PIXEL C has a really best processor, a beautiful premium aluminium body, a new Usb C 3.1, it will have every update as soon as possible, it will have a great stock experience, the bootloader will be unlockable without loosing the warranty.
The galaxy tab s2 is thinner, has sdcard, has 4g LTE, it has multi windows already available.
really, I don't know...

I have both.
Pro's Pixel C:
-Better screen
-Smoother UI experience
-Can be unlocked, still warranty
-Faster charging due to usb C
Biggest Con:
-Horrible wifi (because of this I have to return it)
Pro's Tab S2:
-Thin and light
-SD card (and LTE for you)
-Best wifi ever. Better than expensive Wifi usb dongles.
-Doesn't get hot when reading stuff, browsing (unlike Pixel C)
Cons:
-Pixel C's pro's

Pixel C gets hot when reading? No it doesn't, I've also got a PIxel C.
My Wifi performance is okay so far., about the same as my Galaxy S6.

Mine gets a bit warm where the volume buttons are located. Just browsing and watching youtube.
When playing games, even the screen gets warm. But I do understand it is because of all the metal. My HTC one gets also warm when doing casual stuff. This shouldn't be a point for buying the tablet or not, just worth mentioning when comparing to tab s2
It performs well when you're close to the router, even better than other devices. But with a little distance or a wall between the speed drops down significantly.
Hello guys
I read all the tread but its not easy because I'm from Belgium, I speak French, its little hard for me..
My old asus is broken, I need new tab right now.
I use always in landscape mode in my house for : surfing, YouTube, gaming , modding ..
I'm afraid with 4/3 s2 ...
Pixel c is fine but no possibly hand on ( Google store )
So, guys , s2 or pixel c ?
Have a nice day en thanks you budy
BTW, sorry for my English.
Good morning fellow in my point of view there is no comparison between pixel c tab samsung s2, the pixel c is eaten with potatoes. Sorry for my bad English and a greeting.
Eaten with potatoes? What do you mean?
Envoyé de mon LG-H815 en utilisant Tapatalk
Upon further use, I am finding the speaker placement really annoying. I find that when playing games in landscape mode, my hands cover the speakers and it makes the sound awful. Having the speakers in the corner would have made a lot more sense. Also, the front facing camera being on the long side of the screen is annoying to me, but it's not really that big of a deal. I still think the hard buttons on the Galaxy S2 are a deal breaker to me. That and I absolutely hate Samsung's Android skin. It just bogs down devices and makes for a poor experience.

Yes. The speakers are in the center on the top and bottom if you are holding it in portrait mode. In portrait, there is no problem. It's only when holding it with 2 hands in landscape that you may notice the problem. I have very large hands and that may contribute to the issue, though. I would like to reiterate my suggestion, though. The Pixel C is superior to the Galaxy Tab S2 in my opinion. For the most part, Samsung makes amazing hardware. I can't stand their hard buttons that force you use to use the tablet in one specific orientation. Having the buttons be controlled by Android on the screen is a much more elegant solution. Other than that, the only reason I would not buy the S2 is because Samsung Touchwiz is bloated, resource intensive garbage.
Thanks you Airwolf
I thing pixel is the good choice.
I'm little afraid with Google sav in my country Belgium..
I think I will buy the Pixel c too, but I wait for its availability on Amazon (perfect sav)

Buying a Pixel C over the Tab S2 is one of the worst decisions you can make at the moment. Please read this: http://forum.xda-developers.com/pixel-c/general/mapping-problems-to-serial-t3274660/page3 , the pixel c has broken wifi, a buggy touchscreen and is overall a bud ridden beta device. If you want to pay Google for beta testing their shoddily designed tablet, then by all means go ahead. The Tab S2 is cheaper and less flashier but it is a full baked product and offers a fingerprint sensor, split screen multitasking, a screen equal to if not better than pixel c with impossibly deep AMOLED blacks. I was a believer in pure google devices (and still am with devices like the Nexus 6P that get it right) but Google hasn't made a good tablet since the 2013 Nexus 7. I had to return 5 Nexus 9s due to screen bleeding before getting a good one and am returning my second Pixel C due to bad Wifi.
Until, a second version of the Pixel C is released which addresses these serious issues, the c in Pixel C stands for CRAP.Period.

Pixel C touchscreen issue (video)

Just received the Pixel C and I immediately checked for the touchscreen issue some reviews were talking about.
There's definitely a touchscreen issue. In the video Pixel C is on the left and Galaxy Tab S2 on the right.
(this is not an issue of lag or something, Pixel C is much smoother than the Tab S2. It's the touchscreen.)
watch in 60fps https://youtu.be/Q9illQ7kp_w
I will test this when i get home but I have not noticed any real world use issues with the touchscreen. I used a Note 10.1 2014 edition daily for over 2 years and didn't notice any issue when I switched over to the Pixel C yesterday.
You should try to pinch to zoom on a picture or just in chrome. It's stuttery.
Could you also check if The left side (where the volume buttons are) gets warm... I'm just browsing and it's getting quiet warm.
No stutter here. Pinch to zoom works perfect.
Check your hardware revision, I'm curious to see what others have. Mine is 5
As far as the heat, it's to be expected with such a powerful processor/gpu along with the metal body.

Also 5. I've rebooted the tablet and it's gone for now. I'll let you when it comes back.
I honestly can't see any problems with the video. Is it that the circles don't follow your fingertips as closely?

I believe thats the issue they are trying to show. There is a lag in the touch input in his video compared to the S2
Looking at the video the problem you're probably talking about is a delay between the digitizer and the screen.
That can be fixed by over clocking the display. I also noticed today that when the device is cold 40°F I get that same "laggy" effect. Not worth worrying over though.
Sent from my Pixel C using Tapatalk
I'm finding the touchscreen really problematic. I find I have to make very firm and deliberate touches unlike my Tab S. Even though I can hear my finger tapping the screen, it doesn't register. I can't play "word find" type games because you have to trace the letters so slowly in order for them to register.
No issues here https://youtu.be/Q7gZ6VzrBV4
If it's that bad then warranty it.
If it persists then get your money back.

phone overheating in my pocket

Hi,
Often when I pick the phone from my pocket at work it's like rly hot hotter than when I'm using it in my hands. This is rly worrying for the battery life short and long term. I thought first it was the fingerprint scanner activating itself in my pocket but I disabled it using XTouchWiz and still same issue, except it's unpractical to use.
Any idea?
Thanks

Try uninstalling app installed just before first occurence of overheating, could be a bad app.

I just got the phone a few days ago didn't installed that many apps but there doesn't look like any app that looks bad I only install classics like fb (already tried removing it) messenger Spotify ... what
If you have your phone just a few days, try factory restore, if that doesnt fix your problem, back to the store..
Verstuurd vanaf mijn SM-T810 met Tapatalk
Which one exactly?
I have a a5 2017... Can't return I flashed TWRP couldn't stand stock TouchWiz.. maybe I can get a refund at Amazon ... But I would get stuck without a phone for several days and maybe I would get same issue
BTW when it's idle out of my pocket it's really cold onyl in my pocket it overheats
When I say overheats it is still usable maybe like 30° never got over that
Battery life is pretty decent I cant last two days with my normal usage but I can use it a lot during one day without needing recharge
30 degrees is not overheating. I have an a3, battery temp is 29.4 idle if it heats up above 40- 45 degrees i would get worried...

A phone in a pocket will get near body temperature (30-35 ⁰C) which feels quite hot in your hands since the hands are used to the much lower room temperature.
If something is overheating, it would also overheat when the phone is just lying on the table.

Disable AOD, mobile data and wifi when you are not using them.
