Galaxy A50 WiFi issue and downgrading - Samsung Galaxy A50 Questions & Answers

Hey so I've been having this issue with my Galaxy A50 where the wifi would keep hiccuping in a constant pattern, this is very noticeable when I try to stream games using either Steam Link or Moonlight, the wifi would cut for like a split second each 5 ish seconds. I did however find a workaround, and that it so enable and disable airplane mode, it would completely fix the hiccups.
So today, I regretted updating my phone so much (7th of July update), because now, the hiccups are back and they are more constant than ever. The trick I'd use to make the wifi stable no longer works, I need to keep airplane mode enabled at all times to avoid these hiccups.
I would like one of either solutions: can I fix this issue once and for all, because it's supper annoying, I tried removing my sim cards and all but the issue persists, if there is no fix for this, then I'd like to revert to the previous version I had, I have already downloaded the files from Sammobile, but I'm worried that it would brick my phone or even refuse to install period, here's the ROM that I'd like to install:
https://www.sammobile.com/samsung/galaxy-a50/firmware/SM-A505FN/SER/download/A505FNPUS5BTF1/347209/
I've explained this issue a bit better on the steam forums, so I'm gonna copy what I typed there;
Thank you very much in advance.
Okay so, recently I got a brand new Galaxy A50 phone, and whenever I'd try to stream games (over local network using WiFi) I'd get frequent and consistent hiccups that last about a split second each 3 seconds ~, I suspected that the issue could be from my phone being faulty or whatever, but I tried my brother's phone which is the same as mine, but the issue persisted.
On very rare occasions, the hiccups would not occur and the stream would be absolutely perfect, so I know for sure it might not be a hardware issue and that a stutter free experience is possible for sure, however I have no clue how to keep it consistent.
Mind you I have tried many other devices, my old Galaxy S5 and S6, even tried a Huawei phone and an Oppo phone and they all seem to work just fine, I even tried different streaming services like Parsec, TeamViewer, Moonlight etc... So the issue is certainly not my network as it is working just fine with other devices.
The A50 is a pretty popular mid-range phone so I'd expect at least someone to use Steam link (or similar apps) on it and experience this problem, yet I haven't found a single post about this issue online, the only thread that pops up is another one of mine related to this issue (on Reddit).
Can anybody help me come up with a solution? I tried quite literally everything I can, including updating my OS and all of my apps.
Thank you in advance

2 Issues with Galaxy Nexus: Wifi + Multitouch, temporary fixes inside!

Issue 1: Multitouch issue
- As far as I'm aware of, there is no fix yet and a lot of people are experiencing the issue. What happens is whilst in landscape mode, sometimes, if one finger is placed at the bottom left of the screen, and another is placed on the bottom right, it'll fail to recognize the second touch (bottom right). This doesn't always occur, but does happen at times.
Simple fix: Lock the screen, then unlock it
Issue 2: Wifi consistently dropping
While downloading files, or sometimes even watching youtube videos, the wifi icon will disappear for a split second, then come back and an error will appear along the lines of " File could not be downloaded due to an error" or in the case of the market, it'll just stop downloading and give an error.
Fix: Sadly, the only fix that I have found so far for this issue is to get a new router. See my post here I used a Linksys WRT300N
EDIT: Another potential fix is to change some settings with the router but I'm not sure exactly what settings are needed to be changed.
EDIT2: I've created an issue about the wifi issue over here and according to [email protected]:
Im assuming you are downloading huge files using WiFi... there is a notorious bug still unresolved on DHCP leasing time. If your route is settled to infinite (0 or ffffffff) a local timeout of few minutes is applied, thus the download broke and resume time by time because dhcp renewal. To fix this try to adjust your route settings indicating a discrete leasing time (i.e. 24 hours or 2 days) and thi should fix this specific issue (also noticeble when watching youtube videos, that may freeze after few minutes).
Hope this helps.

Hey everyone,
I have had my Galaxy Nexus from Bell for a few days now, and it is a beast Everything runs smoothly, no lag (even with live wallpaper) and helps me accomplish everything I need from a mobile device ( a hell of a lot better than the milestone - international version of the Droid)
However, there are some prominent issues throughout the device.
1.) The wifi constantly times out, it will stop working at random times even if im 1-2 ft away from the router. Also, when I was downloading SD files for a game (asphalt 6 - 524mb file i think), i had to restart the download at least 10-15 times to finally get it to download. Is this a hardware issue? Can this be fixed through a software update
2.) The multitouch doesn't work at random times. For me, whether its plugged into the charger or not, at random times, when you touch the left side of the device in landscape mode, the device will not recognize touch inputs on the right side. HOWEVER, if you lock the screen, then unlock it, it works flawlessly. I am determined this is a software bug (may not be though) and if it isn't could someone please tell me? Thanks. And a lot of people also have this issue : http://forum.xda-developers.com/showthread.php?t=1385587

I have two question for you awesome people at XDA.
1.) Could someone please either post an issue to Google regarding these two issues or direct me to a website where I can post them?
2.) Could any of these be a hardware issue? Do you think I should return it and get another one?
Thanks so much guys,
Mosh
Would also like to know if the second problem is software related or not :/
EDIT: noticed now that my screen gets really hot at the top. Really hot! Does your get warm aswell?
Don't know. The easy fix is to swap it.

Both my touchscreen and WiFi have been working flawlessly.
I did have some initial hiccups with the WiFi until I power cycled my router.

I've been having WiFi trouble with the Nexus too - the phone generally seems to get poorer signal in comparison to my other devices. I've unticked this box, but it still keeps avoiding connecting (and when I go to WiFi settings, actually says it's avoiding connecting to my network because the connection is poor). It's frustrating, to say the least.
Rather than immediately assume that you should swap the phone, or thinking it's hardware, or (?).
What build do you have? There are at least 3 builds available for the SGN.

Seriously people need to stop making such a big deal of these separate builds.
WiFi could be an issue with the router. I had a problem where connecting Nexus to the router would cause both mine and other users internet in the network fail. Once I disconnected, internet returned. It worked on first few loads, then not anymore. Strange thing is that it fixed itself few weeks later.
(Same happened once with another router and when I was using HTC Desire, Android seems to be a wacky WiFi partner)

Not this. If its software you end up with another phone with the same problem.
You may find other radios help with wifi, check the dev section for details if you have a rooted device. Otherwise youll probably need to wait for one of them to drop via an official ota.
As others have said, uncheck the weak wifi option
In terms of the multitouch issue, just tested my device and can't see any issues at all. Could be software related as the screen itself can support 10inputs - be interesting for users on non standard roms to check and see if they do have a problem as this may lend some weight towards the software related argument.

I get #2 in shadow gun if it goes into sleep mode while i'm playing. Its clearly a software issue as restarting the game it goes away.
Point 1 happens to me too. I've tried multiple ROM's. I'm getting a bit worried that it's hardware. It's dropping every few mins when I need it... then it comes back rather quick.
You have any news or has anyone else experienced it?
I'm not seeing a ton of people talk about this wifi problem, so I'm guessing it's not a widespread issue. I'm assuming it's not hardware either, but I'm curious about it. Whenever I turn on wifi on the Nexus and it tries to connect to my router, it disables all other connections, and the Nexus reports that it's not in range of the router. I'm interested in what routers people are using that are experiencing this issue.
I have a D-Link DI-624, a free router provided by Verizon with FIOS signup. I'm using a custom password, not the one that came with the device. I have a 13 digit alphanumeric password (sorry, I can't remember the exact security setting for it).
Edit: Actually been doing some research on this, and it's appearing it may be a frequency / channel issue, that the phone is broadcasting at a frequency similar to your router. Looking into exact fixes at the moment.
I have no problem with wifi and multi touch.
But I noticed that two fingers cannot be very closely touched it will mingle together. For example if you hold shift button on keyboard it could act like normal shift (turn lowercase to upper or vice versa) but its very difficult to use shift + a
Also lots of games exiting on me, first I thought was multi touch acting up so I could accidentally hit home or back button. But then I think its just matter or compatibility of those games with ICS.

do you know if the latest update solved the touch problem?
Same issues here. On the samung version (dont remember the codename) i had this issue so i rooted and changed it so that google updates my phone. But this didn't help either. Still losing wifi when i am downloading. Like now i was going to download 9mm and after 2 seconds the wifi disconnect until i quit 9mm and then it pops up straight away. Can it be a hardware issue?
PS: before i change my phone brand to google, i could see the "avoid poor wifi connection" but now when i go to advanced tab it's gone :S
Ok everytime i try to test wifi in speedtest it says network communication issues after 2 sec of testing. Any info please? Do i have a faulty unit? going crazy over here
For what it's worth, I haven't had either of these problems on my Galaxy Nexus, and it's been on a lot of WiFi networks.
I've gotten speeds in excess of 20mbit/20mbit via the speedtest.net app multiple times on the campus wifi, as well as my parents', and my dorm connections. I've downloaded the Asphalt files twice without any interruptions either time, and I've never experienced any problems.
As for multitouch - no problems with that either. To type in all caps you can hold down the caps button on the keyboard and type - it's never given me any issues. I don't think I've been in a situation where I've felt multitouch hasn't performed right.

Multiple ROMs doesn't mean much, they all share official driver binaries and radios that are available.

[Q] Note 2 Won't Receive Data Packets on WiFi!!??

Hi all,
I recently sent my phone in and got it back probably little less than a week ago. Samsung had to replace the motherboard on my phone as it had the infamous SDS syndrome. I just realized the other day that when I connect it to WiFi at home, I can't upload my apps on the Play Store. I can still surf the web and everything, but most of the apps just don't connect to the web.
Is there a solution to this or do I have to send it again? As you probably know I don't want to do that because it's extremely frustrating. Should I try doing a reset to see if this helps the solution or ?
I know that it worked on another WiFi hot spot (my work) on Friday, so this issue just happened recently. I'm pretty tempted to do a hard reset since I don't have everything downloaded and reloading my contacts won't be that big of an issue. Any recommendations will help. It also states that my WiFi download speed at home is 72MBPS when I check the network I'm connected too.
Many thanks in advance for the help!
EDIT: I have not rooted my phone and don't plan too anytime soon. I'm considering on selling this so I can get the Note 3, but after the couple of issues lately, not sure if I wanna stick with the Note at all.
EDIT 2: Weird, it seems like it works in my room but not in my living room...I just realized that now which is extremely annoying, any solutions or suggestions as to what might be causing this?
EDIT 3: And it's not working again...I cancelled the download and tried downloading it again and it works again! This is frustrating....any help would be appreciated!

[Q] Problem with WIFI auto connect in Android 4.3

Ok, So this has been happening for a while. I kept looking up for a fix, and i finally foudn this issue ticket open that looks like others having the same issue, and it appears to be this specific phone.
Is anyone else having this problem and is there an easier way to solve it than resetting the device?
Goggle issue 58230
I will copy the first post, as it pretty much mirrors my experience.
My wifi is always on (turned on the option for keeping it on even when the phone is idle). With older versions (4.2.2 and older), when I arrived at home, the phone automatically was connected to my home wifi.
But when 4.3, sometimes it doesn´t connect until I enter the wifi menu.

Lyian, I have the same issue as well, on google stock rom as well as all the modded roms, whether 4.3, or 4.4. I may have to junk my (otherwise perfect) phone just for this. I don't see any solutions anywhere.

CM11, random data blackout

Hoping this might ring a bell with anyone who has fiddled around with the GN and CM11.
The CM11 update notification won me over and I pushed CM11 (11-20140308 snap - toro) a few weeks ago.
Interestingly enough I saw a HUGE battery drain improvement. Possibly an oddity unless others have noticed this too.
Anyway, the big issue when using CM11 is random data blackouts. The phone can be on 3G, 4G, or Wifi and it will act like there is no data access. eBay app and Chrome give the 'no connection' type error with other things like email just not updating.
The fix so far is to reboot the phone. As soon as it comes back up the data portion works perfectly. Not the most time effective solution especially if trying to get important data on the go.
I know Google has marked this phone as past it's prime in terms of support, but with CM still supporting builds for this device I'm hoping something may sound familiar and somebody could give some words of wisdom for this problem. With the Nexus 6 device slotted to be released in the summer/fall timeframe I'm holding out on replacing the GN.
Ideas anyone?
change other kernel/boot.img
Sent from my Galaxy Nexus using XDA Premium 4 mobile app
well yes but I was also interested if anyone else may have been experiencing this.
if this is the same issue I've seen in some ROM threads then yes you aren't alone.
instead of doing a reboot, have you tried toggling airplane mode on then off? if that works, you'll spend way less time vs waiting for boot up
glad to know I wasn't alone on this one!
The 'no network found' issue just came up a minute ago. Probably had tried the airplane mode before but in a hurry I defaulted to restart.
The quick switch between AP mode and back did bring the connection back, although with the phone starting up fairly quickly the different between doing AP mode or restarting seems to be differently by only a second or two.
If this has been seen with some ROMs, what have people turned to as an alternative?

Wifi connection keeps dropping in Chrome - ERROR -->dns_probe_finished_no_internet

Hopefully someone here can advise me on this issue I have been getting with my Nexus 5x and using chrome but issue also happens in youtube. Note I have not setup my phone with a SIM yet, just been testing out the phone features and Android 6.0
When connected to my home networtk chrome and youtube work fine but every now and then the web page loading seems to stall in chrome, and then i watch the wifi signal disconnect and then reconnect and then the web page will load, but before it does i get the error message
dns_probe_finished_no_internet and sometimes its ERR name not resolved or ERR_NETWORK_CHANGED or similar inside chrome.
it seems to recover after about 30secs and then i have full wifi again. it just keeps happening This seems to be random at the moment but is consistent. My home network is pretty solid and all my other devices work fine and do not exhibit this issue, my wifi is solid.
I have done all the usual forget network, wipe system cache and static IP etc. nothing makes a difference. can anyone shed some light what might be causing this?
thanks
Did you manage to solve the problem? I got my phone last week and I am having the exact same problem.
I should mention that I am on stock unrooted and using At&t network. I checked the wifi connection from my older phone lg optimus g and it seems to be fine. It keeps on disconnecting and reconnecting on my 5x though and I think that is draining the battery faster than anything else. My top two battery uses are android system and android os rather than sceeen.
Do you think it is a hardware problem?

Have the same problem with mine after one week's use. Was fine until this morning.
On hold with warranty service now and will be getting a replacement.
Don't wait, use the warranty.

Any luck getting rid of the problem? I even factory reset my phone but the problem is still there. My problem is also global, not just in chrome. I think that there is a problem with the wifi of the phone. I do not want to root and install a new kernel as of yet. Just want to stay on the stock rom.
What did the warranty service say? Is this a common problem with the 5x? I would rather not RMA if the problem can be solved by some other means. I put on the screen protector so well. Don't want to do it all over again lol.
Also, is Android OS on the top of the list in battery drain? It is for me and I think the wifi connecting and disconnecting prevents the phone from sleeping.

Tried everything, reset network connections and then tried a complete reset and attempted new setup but the wifi was too flaky to complete the setup. Since the problem happened while I was using the phone I was not able to observe the effect on battery life. I would imagine it would take a big hit trying to connect and failing continuously.
Did this before calling Google so I wouldn't have to do this while on the phone. Warranty Service did not mention any ongoing problem with the wifi.
Am setting up the replacement currently. I'll save rooting, etc. until I've used the phone for a good while.
Bite the bullet and send it back. It's not going to heal itself.

oops sorry I should have said im in the UK, dont worry il find it. Can I ask is your replacement phone working correctly now, no wifi drop outs as before? if so what version of marshmallow are you on?
I've only been using it about 8 hours but no problems so far. The phone updated to 6.0.1 during the initial setup.
You can find the phone # for the UK by using a 'Contact Us' link in the Devices Store on Google Play.
ok so I seem to have fixed this issue been having and it turns out the phone itself is fine. The issue was with 2.4Ghz wifi networks. There are quite a few in my local area and there is probably a lot of cross talk on channels. So i setup a 5GHz network and my n5x seems rock solid since ive connected to that. no one single drop out all day! speeds are also much faster im getting 150MB download speed on wifi lol...
i changed nothing else on my phone just for the record. hope this maybe also helps someone else

I think I have an issue with the college wifi as well. I asked my friends who are using the same wifi network and their phones also do not seem to remain connected. I thought that it was an issue with my phone but I guess it is not.
To test that, I connected my phone to my college wifi all night and when I woke up in the morning, more than 20% battery had been used probably because of disconnecting and reconnecting continuously. The next night, I connected to some other wifi and there was less than 3 or 4% drop in battery overnight.
I hope they upgrade the college wifi as the battery drain is very annoying.
