Continuous WiFi disconnections after update (A202F)

[Magnus O]

Hello all. We have two Samsung A202F's, which recently received an update to version A202FXXU3CUJ2.
The two phones received this update with a week in between.
For both phones: after the update was applied, we're having WiFi connection issues.

Wifi drops out randomly with an explamation mark for 'no internet' whilst this is surely present. Disabling/re-enabling WiFi clears it for a few minutes, until it happens again, and again, and again, etc. So far, it seems that if we disable mobile internet, the Wifi seems to remain stable.
Before this update, there was no issue.
We've reset network settings, cleared the wifi connections and re-established them, and even cleared the phone's android cache, all without succes. The problem remains.

Anyone else experiencing this?

For Samsung members, here's the replies to your standard questions:

1. It is up to date
2. We did. Its not the access point, but happens with every access point.
3. Wifi calling was on, we tried if disabling it helps, but no change.
5. We did, see my first text above.
6-7. there is no third-party app that caused this.
8. It was surely the phone update that caused this. Consequently for BOTH phones. We will surely not reset, as that takes a huge amount of time to re-install to normal. And it is a matter of time before we receive the update again, on which we are back to square one.

Because it's an issue with your internet connection despite that the other devices doesn't have this issue. Perhaps a Wi-Fi signal booster can resolve this for you. All your devices uses different antennas which can also result in a difference between the connection quality.

Kind regards,

It surely is NOT a router/access point issue: The finding from rbeltman that it happens less frequently / does not happen when on charger, and the finding that the problem only happens when WiFi is shortly idle, confirms that it has something to do with some kind of energy save mode of the phone's WiFi connection. This is also our exact experience.

For example: if you're watching a YouTube video there's no problem. If you use data intermittently (WhatsApp / browse the web), without anything else in the background using permanent data, then it keeps dropping out. I have to re-connect every 2-3 minutes sometimes.

Please also check my first note, where I explain we have two phones of this type that both give the same problem ever since they received the last update. One device received the update about a week later than the other, which matches with the moment where the problem was first experienced on the devices.

Again, I'm convinced it has to do with some kind of WiFi energy save mode that was changed during this update. At least, it is very annoying and has already caused my mobile internet subscription to run over its limit, with resulting costs.

And yes, the problem has been raised at Samsung through the members app.

Thank you for your reply! You've also mentioned that you've send in an error report through our Samsung Members-app, your phone will send a log combined with the error report. My colleagues of the R&D department can investigate this further with this information and hopefully you will receive an update to resolve this issue.

Can you perhaps share a screenshot of your Wifi connection settings? Go to: Settings > Wi-FI > push the 3 dots > Advanced. I will share this with our product specialist to get a closer look for a possible solution. 

Kind regards,

Martijn

Here's the settings in writing (because the screenshot is Dutch):
- switch to mobile data: OFF (and greyed out);
- enable wifi automatically: OFF (and greyed out);
- show network quality info: ON (I just enabled this to try and fault find the issue)
- Hotspot 2.0: OFF;

Perhaps is it worth noting that both myself and user 'rbeltman' are Dutch? Could there be something in the update that only affects certain locales perhaps? Seems strange, but just a note.

Om het dan misschien wat makkelijker te maken, je kan deze schermafdruk ook in het Nederlands delen 😉

Groeten,

Ik moet hem via de web browser sturen, want de Samsung Members App zegt standaard 'server error' bij elke schrijfactie die ik ermee probeer, ondanks dat hij vers geinstalleerd is (nieuwste versie) en er gewoon verbinding is. Bij deze:

[rbeltman]

Gezien we al over zijn gegaan naar het Nederlands, reageer ik voor de snelheid/gemak in het Nederlands.

Ik heb een foutrapport gestuurd, maar nog geen reactie ontvangen. Nadeel is wel dat de Samsung Members app niet wil opstarten als er geen internetverbinding is en je dan niets kan doen. Een beetje kip-ei verhaal. Als het probleem er is, kan je niets sturen en anders lijkt het net alsof er niets aan de hand is.

[MartijnK]

Dank jullie wel, ik ga het aan mijn kant ook doorzetten naar onze product specialist en zodra ik meer weet stuur ik jullie ook een berichtje.

Groeten,

Martijn

Mocht het nog handig zijn, nog een paar screenshots in de niet werkende variant. Alles is hetzelfde voor de werkende variant, alleen staat de optie router beheren erbij. Netwerknamen heb ik verwijderd uit de screenshots.

A friend of us reported today she didn't receive the messages I sent her due to WiFi connection issues on her own phone. Upon asking, what do you think...?
She as well has a Samsung A202F, and she as well just installed the update recently!

So thats +1 for another user experiencing this exact same problem. She is located in the Netherlands as well with the Dutch language for the user interface.

Samsung, this starts to get serious. And still very annoying. Can you please raise priority on solving this. Thank you!
