This sucks to see. I'll be getting my phone delivered to me next week, until then, I hope that the issue is software-side rather than hardware-side, this is a huge issue! I hope something is done about this.
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
Hope you get an error-free unit from a later production batch. :good: I can't believe Samsung is not aware of it.
[Samsung Galaxy S20 FE Questions & Answers] MeNtAl_DaRkNeSs:
Hi everyone,

Very bad news... As advised from the Samsung's technician during the remote session, I went to send the device do repair and... the tech support on site said it's a normal behavior of the screen, because it's a multi-touch screen, so it's bond to act like this, obviously I called him crazy and that he's wrong, but they continued to argue that there's nothing they can do to fix it because there's nothing wrong with it, so... I immediately returned the device to Vodafone to get back my money.

Lesson learned... never gonna buy Samsung ever again.

Thank you all for the feedback
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
Come on, do not take it personally. Either this technician is paid to say this avoiding refund of Samsung, or not really well trained and has no idea what he was speaking about. If this would be normal, it would work fine. I have tested it on 5 different phones, plus the S20FE. The latter is wrong, period. And you are right, period. At the end of the day, you get your money back. So do I :)
[Samsung Galaxy S20 FE Questions & Answers] simsaraga:
Guys what do u advice for this issue. Should i send back phone
[Samsung Galaxy S20 FE Questions & Answers] el6006:
I just did the test app on mine. It failed also but not as bad as in the video. Only a few lines crossed over. Now, having said that, after disabling all those gaming related apps, my phone doesn't suffer as bad during normal use. In fact, it seems almost fine with a hiccup only every once in a while. I also went ahead and disabled that app that was showing up taking lots of battery in the background, CameraLightSensor, and my battery life has improved. I look forward to any software updates though.

Many owners over the net claiming they are calling Samsung who say they aren't aware of it yet its listed under the October patch View attachment 5120883
[Samsung Galaxy S20 FE Questions & Answers] propov:
I have latest October patch and the problem is not solved. I think that better is to return the device. I have one week more to do.
[Samsung Galaxy S20 FE Questions & Answers] xphyle1971:
Samsung has just issued a fix for the touchscreen issues of the FE in Korea. Hopefully it will come to the rest of the world soon.

[Samsung Galaxy S20 FE Questions & Answers] Deonix:
updated post from 25.10. Yeah I have the issues in ATJ1 update. Waiting for the newer update.
[Samsung Galaxy S20 FE Questions & Answers] Davey Dual Sim:
The October patch has improved it but not completely gone when I do the test using the app, however in real use I've yet to have any issues
[Samsung Galaxy S20 FE Questions & Answers] sireniankyle:
Ran the test, and I am not having these issues. Running a North American G781U1. Not sure that it matters, though.
[Samsung Galaxy S20 FE Questions & Answers] jtOttawa:
As mentioned in another thread, Samsung is rolling out a second update to address the issue: https://www.sammobile.com/news/samsung-improves-galaxy-s20-fe-touchscreen-two-firmware-updates/

Clearly (and, as usual, in my experience) Samsung Tech Support has no clue what they are talking about when they say they have never heard of this issue.

I should add that, as the OP suggested, the variability of the issue for users would seem to suggest a hardware defect rather than a software one - I certainly hope that Samsung is not trying to mask a hardware issue through software tweaks.
[Samsung Galaxy S20 FE Questions & Answers] malikson30:
Hi,

I've checked new update ATJ5. The same issue as in 1st post. I wonder how to achieve that situation on "production"? I was play on COD - nothing, play on Genshin Impact - nothing, zoom in zoom out - nothing.
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
Read that article earlier today. I will be curious if it solves the problem. ATJ1 definitely not, it was in the video. I have re-sent the unit, but if anyone had problem with earlier firmware, please also check on ATJ1, and especially on ATJ5 and give a feedback please.

If it is not _perfect_ (like the other 4 phones in the video), it is just another cosmetic issue for covering a probable hardware defect / weak point.

I really hope it was a software problem. Different finger handling would suggest that, but maybe this cannot be fixed on software, rather than touch panel firmware level. Fingers crossed.
[Samsung Galaxy S20 FE Questions & Answers] Davey Dual Sim:
AJT1 definitely better for me , but not completely gone
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
Thanks pal! If still the same crossing lines as in the video, it can still have wrong movements, zoom issues, etc, because in that case different fingers are sensed as the same. Even if it happens only rarely, it happens. 2-3 times a day means 1000 times a year. Annoying.

You know, if your car can fail if you turn the wheels to the left, you can still go straight with that car. But if you have to turn left... My (our) problem is that we paid for a car that should turn left and right properly. Every single time.
[Samsung Galaxy S20 FE Questions & Answers] miquelbe:
ATJ5 fixed all the issues with my device. I was having erratic response and ghost touches and now they are completely gone.
[Samsung Galaxy S20 FE Questions & Answers] xphyle1971:
Damn. I'm unlocked in the USA. I haven't got a single update since I got the phone. Still on September security patch. How can I get the fix?!
[Samsung Galaxy S20 FE Questions & Answers] jackher0r:
I can confirm I also have this issue. Ran the same test in the video. I have the US Tmobile version.

edit: I have noticed issues while gaming that i did not have on my oneplus 6 or other phones. Not a happy customer =\
[Samsung Galaxy S20 FE Questions & Answers] coolmaster121:
never noticed the issue until i ran the test. I def have it
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
Unfortunately, many people has it. As it is seen, for some, the latest J5 firmware fixes the issue, but for other, it doesn't.

I really hope Samsung is not "covering" the hardware issue with software "emulation".
[Samsung Galaxy S20 FE Questions & Answers] fncd:
Samsung seems to think this is fixable via a software update - in fact they have supposedly released 2 of them. . . if you live in the right country that is. I've decided to return mine. It is simply unusable if it's plugged in.
[Samsung Galaxy S20 FE Questions & Answers] :
I got two updates the last few days and don't have any touch screen issues
[Samsung Galaxy S20 FE Questions & Answers] Jikx:
Definitely have this problem, on ATIG.

I've found that very light and quick flicks on both sides of the screen really accentuates the issue - like it makes it go berserk! https://streamable.com/tz5hnv

Would appreciate if someone on the latest firmware could confirm this doesn't happen anymore, thanks.
[Samsung Galaxy S20 FE Questions & Answers] :
Hi to everyone,

I also bought the S20 FE 5G from the official Samsung Webshop in Germany.

I already installed and tested the newest firmware "ATJ5" and still have the issues like in carlosmeldano´s video on youtube.

With the App "Phone Info *SAM*" I was possible to check the production date. My phone was produced on the 15th Sep. 2020. The colour is mint green.

I would be very happy if those who have no problems with the tochscreen could check the production date of there device. Maybe this will help to identify unaffected devices.

Thanks
[Samsung Galaxy S20 FE Questions & Answers] maderos:
I have no problem with touch. Mine is 16.09.2020

Sent from my S20 FE 5G
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
I had a blue one, same DBT region, same S20FE 5G, Blue color, manufacturing date 11st September. But I know people who also have units from the first batch and have no issues. But it is definitely worse at those from the first batch. Some reported that they exchanged, and they got a newer version which had factory-installed ATJ1 firmware, and had no issues fresh out of the box.

It is still not known if all the units are affected, only early units are affected, or only some of the early units are affected. Because neither ATJ1 nor ATJ5 fixes the issue for all the people, there might be those units having real hardware issue that will never be 100% fixed, but to an "usable" level.
[Samsung Galaxy S20 FE Questions & Answers] Huberttus:
I didn't notice the problem before doing the test. G781B, manufactured 18/9. Device is up to date.
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
And you are not alone in this. This "problem" what you see in the video is not really noticeable in the everyday use in the first few days for a new phone. If you notice it, you might think that you have mistouched the screen, so you blame yourself in the learning period. But after you start to notice strange scrolling, ghost touches, not precisely working pinch zoom, etc, you start feeling that something is wrong with the device, but

you cannot reproduce it clearly

.

This is what this video is for.

If you see ghost lines in the test, or crossing line, than your unit is definitely affected and working wrong. If you are a one-hand user, you might never experience it, but if you are a heavy user, or game on the phone, you will definitely experience the problem in normal everyday usage.
[Samsung Galaxy S20 FE Questions & Answers] MarkMar1234:
I am happy to share my experiences today with you.

I contacted the German Samsung support by phone and the problem was well known there.

However the service employee could not tell me which devices were affected in detail.

He only mentioned that they are currently receiving a lot of inquiries about touch problems with the S20FE.

I agreed to his suggestion that I should contact the official Samsung on site Support "Samsung Service Plaza". Luckily one of there shop is around the corner.

There the colleagues were able to reproduce the issues. As a solution they offered me a whole display change.

I refused this because the device is still under the withdrawal period of two weeks.

A replacement device will now be delivered directly to my hands. I will report whether the errors still occur with the new device.

To my use case:

I regularly work with CAD programs/viewers on the smartphone. Multitouch input is absolutely necessary in order to be able to select or rotate individual parts/assambly groups correctly.

The touch issues resulted in spontaneous rotations of the entire model or even worse unwanted marking/deleting of assembly parts.

For such programs the issue is simply not acceptable. I also tested the App with a sperate Bluetooth mouse and with this setup everything just work fine.
[Samsung Galaxy S20 FE Questions & Answers] Deonix:
Mine is made 23.09 (as per the app mentioned above -Phone Info *SAM) It has the issue. Apparently i was testing it wrong.

EU 5G version. First thing monday morning I am contacting Samsung for a replacement unit. My device is not up to date. Still on the AJ1. Probably will get it in 1-2 days.
[Samsung Galaxy S20 FE Questions & Answers] :
I bought in the EU in Poland without the XEO operator and I have the ATJ5 version (The phone was produced on September 16.). I have no major problems except for one.

Unfortunately, I did the test and I have a problem with lines crossing. Tested in-app according to YouTube instructions by CarolsMeldano.

I have 2 more days to return (14 days) and I don't know what to do. Will this issue be fixed after the upgrade or is it a hardware glitch?

Is there anyone in the forum that has no problem with the line crossing on the S20 FE? Can anyone document this by video? Somehow I don't believe there is at least 1 device that is working properly. Most likely, people just didn't discover it.
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
Honestly, I tend to think that this is a hardware issue which is corrected again and again with firmware update, but it will never be guaranteed that it will be fixed 100%. Check comments and you will see that the ATJ5 firmware fixes the problem mostly, but there are still crossing lines, but very rarely. So, these are masked, but not solved.

I have returned mine, I don't wanna experiment with a 700€ phone. Instead, I will wait until it is surely confirmed that the problem is 100% solved.
[Samsung Galaxy S20 FE Questions & Answers] :
So I have to understand that the ATJ5 version still does not solve the problems with line intersection not only for me, but also for all?

This phone is also so great that I feel sorry to send it back.

But if I do, I will wait until the situation clears up and for Christmas it buy be version 256GB / 8GB Ram
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
This is true. Problem is not solved for everyone with the ATJ5 firmware. More reports not resolved or partially resolved than fixed. So far, it still seems to be uncertain, whether you will or will not have problems when you but a new device today. I will definitely wait with re-buying it. Maybe Samsung changes the manufacturing technique or replacing some "weak" parts on new production units. 5G 8G/256GB is also my target, but that will only appear widely later.

In fact, I know about at least one Czech 5G 8G/256GB official unit from the first batch, which had this problem, so that is also affected, hence it is a very rare version, and up today, only sold in Czech Republic officially.
[Samsung Galaxy S20 FE Questions & Answers] capt_f0r3st:
Hi, that was my intention. I am from the Czech Republic and I was thinking that buying this (not so common verison) would give me some chance that I will be spared of this issue. So not a good news for me :( So thanks for kind of confirmation. So I am gonna wait a little bit longer or just look for another phone.
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
Actually, a guy from Slovakia reported he bought the 8/256 version about 2 weeks ago, but he has already sent it back because he also had the problem. It seems that the first production batch was mostly affected. Now it is better to wait for some newer version (like EU-wide 8/256) because that would surely be a new production batch.

But until it is not 100% confirmed by all users that a firmware update solved the issue, we cannot be sure.
[Samsung Galaxy S20 FE Questions & Answers] mmuntean2:
Bought the 5G White variant, with 6GB/128GB on the 30th of September. Quite fast I've noticed problems with the touchscreen in different apps: swipes were registered as taps, virtual joystick in COD was moving on its own despite me having the thumb on the same position on the screen, keyboard typing a mess with wrong letters pressed. Then, the first October update came and I installed it with Odin. The swipe/tap issue was 99% gone, but the ghost touches in games like COD and the typing issues were still there. There are some rumors that Samsung used a lower quality touch sensor, which if true, cannot be fixed by any sort of software updates.

I decided to return the device, not waiting for another update that won't fix a thing. I also did the Touchscreen test with that application and had the same problems there as well, like documented by others, lines appearing randomly when swiping.

Too bad, I was quite happy about finally having a Samsung phone with Snapdragon, in Europe, and Samsung managed to screw things up..
[Samsung Galaxy S20 FE Questions & Answers] Beuzer:
Also just returned mine (just in time to get my money back). I'm not confident they will fix it with a patch. A previous patch already stated it should fix the problem and it didn't. Too bad, finally a SD samsung in Europe and then this..
[Samsung Galaxy S20 FE Questions & Answers] olegaku:
S20 FE (SM-G781B) In Australia on Optus here, had ATIG from day one - definitely had issues with ghost touching, etc

I've since updated to ATJ5 (Manually, Australian carriers are notorious for slow updates) - things have definitely improved, the response is better but not 100% and I am still getting the criss-cross pattern on the Touch Screen Test app.

Basically, on ATJ5 it's at the point where if I didn't know about this issue from Forums and testing using the app, I probably wouldn't have noticed it. But I can't un-know the issue in the product that I paid decent $ for - especially moving from Mate 20 Pro where screen response was impeccable.

On a side note, browsing the Samsung update server I've come across ATJ6 for the Chinese version,

SM-G7810/TGY

Maybe it's another fix that is to be released soon for SM-G781B
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
This is the point what annoys me, too. If you have a problem, it can be fixed. But if you can't fix it the cheap way, you mask it out. There were 2 firmware updates in 2 weeks (ATJ1, ATJ5) that were targeted to fix an issue which is still there. We can say okay, they tried to quick-fix it and then they investigate in the background, but we are speaking about an essential part of a smartphone, namely the touch panel, and this model has no special features or anything new, just an ordinary, modern, 240 Hz sampling rate touch panel, which type is in many other phones. And they needed to release 2 firmware updates very quickly, but still couldn't? Without an announcement stating that "yes, sorry, we had a problem but we will fix it, please wait a few weeks"? Why is the rush? Why is it not fixed yet?

If they let it go and just mask it out 95% for a 700$ FAN EDITION phone, I would feel it as spitting in face of fans. Then why did they released this phone? They ordered too many SD865s which they couldn't sell and it is cheaper to put them into these half-designed, medium-quality, high-priced units not to cannibalize the normal S20 line sales and even not the S21 line?

I know what I say, and I really hope that I am wrong.
[Samsung Galaxy S20 FE Questions & Answers] xphyle1971:
I got my S20 FE from Amazon and am also having the screen problem. BUT...Amazon is now allowing holiday returns until January 31, 2021. So I can hope for a fix until then and play with the phone for almost 4 months before I decide if I want to return it for a full refund. :D Gotta love Amazon!
[Samsung Galaxy S20 FE Questions & Answers] olegaku:
Looks like Following ATJ5 Samsung will be pulling the "This is normal" line....

Quote from Korean Samsung Support Forum-

"Hello. I am the person in charge of Touch HW.

The multi-touch malfunction of the Galaxy S20 FE product has been improved in the latest S/W (TJ5 version).

However, in the specific touch test app as above, when multi-touch by making the distance between two fingers close

The phenomenon that the lines merge into one or the oblique lines are drawn irregularly is due to the characteristics of the capacitive touch sensor.

It may appear as a result of changes in electrical properties that occur as the fingers get closer.

Also, the phenomenon may differ by model.

This is due to the difference in the implementation method of touch operation by model and is not a product problem.

It is not a part that affects the performance when using it, not a test app, but we will

continue to review the phenomenon, so

please always update the S/W to the latest version.

Thank you."
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
So, this is a hardware weakness and they don't want to change it by replacing the touch panel to a higher quality one, but masking out with firmware updates until it is 90%+ solved.

Good, thanks, at least we know their intentions...
[Samsung Galaxy S20 FE Questions & Answers] malikson30:
Exactly. It means that touchscteen with this capacitive technology for this Phone model is not well grounded. So this is HW issue. For other phones like old S7 and probably others as well, they use

capacitive, and there was no such issue....
[Samsung Galaxy S20 FE Questions & Answers] :
Not necessarily. Watching this video of a person who seems to know a bit about the panels in phones, it shows that the problem with lines close to each other occurs even on the iPhone 11 Pro, i.e. flagship products.

Unfortunately, I cannot post links yet because I am a new user. So put this on YouTube and then search for a movie:

아니 이건 좀 ... 갤럭시 S20 FE 디스플레이 이슈 테스트 해 봤습니다.

We don't really know and maybe we won't know what is the cause. I'm curious what will come out with these screens. As a last resort, the iPhone 11 Pro or iPhone 12 remains. But I prefer android. And I was so happy that Samsung will give Snapdragon in Europe, but as always, there must be something wrong. I don't like the fact that it doesn't have a proximity sensor and those screen issues that I personally had too. The only advantage of this situation is that if you manage to solve the problem, I will order a better 5G 256GB / 8GB Ram unit
[Samsung Galaxy S20 FE Questions & Answers] carlosmeldano:
I have seen this video days ago, but they are talking about an other issue, when two fingers are two close and sensed as one. That can be like that "by design", but the crossing lines show incorrect finger recognition, and there are also the ghost touches. So, this argument seems dumb to me, and if a dumb person is responsible for a HW development, I question the quality.

As malikson30 stated, it might not properly grounded, so more sensitive to electrical interference. I have also speculated on this days ago, that this might be caused because of Gorilla Glass 3, which has a different structure than GG4+, and that might also cause this.

We are speaking about a 700€ phone with:

- touch screen issues

- color banding / tinting on panel

- weak, fragile glass front panel

- no proximity sensor causing in-pocket accidentally turn-on, and enabled screen while making calls

- huge draining in 5G mode

But at least I start to understand what FAN EDITION refers to. You gotta be a real fan if you pay that much for a phone that is normally a catastrophic failure. Even if according to the hardware components, it would be a good buy in this price range, because of those weaknesses, it's real "value" is not even half of it.
[Samsung Galaxy S20 FE Questions & Answers] kuailan:
I have non carrier Australia version straight from Samsung. How do you get update? I have been waiting for update to fix this touch screen issue but so far until today still nothing available. Can't believe Samsung still has not release here in Australia.
[Samsung Galaxy S20 FE Questions & Answers] Deonix:
It's not really the same. If the Cheapest Samsung on the market- A01 Core $100 worth- doesn't have this issue, which it doesn't... then this is more than a simple flaw.

I tested with 5 phones. LCD/Oled, new and old -2017 S7 Edge being one of them. None have this issue. So HOW is this normal for this phone and not normal for basically any other known-brand smartphone on the market? How they passed this in QC on a 700$ phone and thought users wouldn't mind it on a "Fan Edition". But we got the S20 GT edition. (Ghost touch) This is the ugly part of this issue. At least with the Note 7 they tried to put a bigger battery and didn't test it enough.
[Samsung Galaxy S20 FE Questions & Answers] xphyle1971:
It's not out in the USA either.
