Wi-Fi issues on the Galaxy A57
In our Samsung Galaxy A57 review, we were very positive about the Korean brand’s smartphone. However, not every user shares this view. This is down to a persistent Wi-Fi problem. Reports of this issue have been circulating for months, but Samsung has still not resolved it. The problem seems to occur mainly in homes with a mesh network, where the device can switch between Wi-Fi access points. When this happens, the connection becomes unstable.
Han raised the alarm on DroidApp, and following research by DroidApp, it appears that Han is not the only one experiencing this problem. Han had this to say about it:
“As soon as you walk through the house and the phone tries to switch to a different Wi-Fi access point, the internet speed drops completely (sometimes to as low as 8 or 36 Mbps). I then have to switch Wi-Fi on and off or activate aeroplane mode; only then do I get full speed back (around 600 Mbps). So I have to do this whenever I step outside for a moment or have been up in the loft. The Wi-Fi does work all the time, but the speed varies enormously. Even when I’m just sitting in the room, the speed drops out from time to time. It’s all rather unpredictable and unstable.”
Users have already tried various solutions. These include resetting the network settings, switching ‘Smart Wi-Fi’ in One UI on and off, and even setting the phone to connect only to the 5GHz network. Even multiple restarts and resetting the Wi-Fi connection do not provide a lasting solution.
Another user describes the problem as occurring on a Wi-Fi 6 network at 5 GHz with an 80 MHz channel width. According to him, the switch to a different access point goes through technically, but the connection speed remains inexplicably low until the Wi-Fi connection is manually re-established.
It is striking that other Samsung devices on the same network do not appear to be affected by this behaviour. Users have cited the Galaxy S24, S23 FE, S22 Ultra, A73, A36 and A26, amongst others, as devices that switch seamlessly between the same mesh access points. As several users are reporting the same issue and other devices on the same network are not experiencing any problems, many suspect that the cause lies in the Galaxy A57’s software or One UI 8.5. Samsung has not yet issued an official response. The recently released June security update also does not appear to resolve the problem.
Response from Samsung
We have brought the issue to the attention of Samsung Netherlands. We have also provided examples, such as Han’s case. Unfortunately, despite repeated attempts to contact them, Samsung has not responded to DroidApp. Should Samsung provide a response following this publication, we will of course add it to this article.
For now, we are mainly waiting for an update that addresses this issue. Hopefully, that will be the solution to this problem.
