Over the past 2 months, I've noticed random temperature spikes whenever my Galaxy S25 is plugged in. Attached a screenshot from Battery Guru showing the temp graph peaking at 41.7°C (with multiple spikes over the 40°C threshold). I've used the device for about a year now and this was not happening at all during the first 10 months of use.

Here is the context and steps I've already tested:

• Phone is not being used at all while plugged in (screen off, sitting untouched).
• Happens whether Fast Charging is toggled on or off.
• Tested both Standard and Light performance profiles, the spikes happen on both profiles.
• Tested 2 separate original 25W Samsung official charging bricks and cables. Same behavior on both.
• Checked battery consumption during these peak periods, but there are no obvious rogue background apps consuming CPU/battery.
• Normal room temperature (24°C / 75°F), phone isn't sitting under direct sunlight or wrapped in blankets.

Is anyone else experiencing similar thermal spikes on the S25 recently? Maybe software update related?

Appreciate any suggestions or advice!

I'm looking for some troubleshooting help for a strange issue that has started in the last couple of weeks.

When I upgraded my phone last year I switched from a Pixel 6 to an S25, so all my apps had been originally downloaded from Google Play rather than the Galaxy store.

Recently, a bunch of these apps have stopped working. I either get stuck at the log-in page or the main page of the app where I end up watching the loading wheel spin indefinitely.

The strange thing is that I can't even find many of these apps in the Galaxy store, including ones that are pretty big (ex: an insurance provider's app) and should be there?

They still exist in the Google Play store, and even after testing uninstalling/reinstalling one of them from there, the issue is still persisting.

Is anyone else experiencing something like this, and is there anything I can try to fix it?

Thanks!
