What is Reddit's opinion of TempMonitor?

From 3.5 billion Reddit comments

This one does provide temperature, but I'm pretty sure that's the temperature of the battery (although I assume that also gets hot when your phone gets hot). Also, I don't know how accurate that is since the SoT doesn't seem accurate either..

I've had my phone also get quite hot every now and then (not lately now I think of it), but never so hot it bothered me. I certainly never experienced a drop of settings by the phone, as I've seen other people get...maybe mine doesn't get as hot?

I hope they can fix the issue in a software update, and if not bring it to a Samsung store and see if they can do a hardware fix under warranty... I'm not doing this anytime soon though since it's not bothering me.

Edit: quick Google gave me TempMonitor, which can measure the phone's temperature, if your phone has a device to measure the temperature, which most phones don't. Most phones only measure the battery temperature...idk about the S20 though.

To start, make sure your tablet's power management isn't set to power saving mode and throttling your performance.

Next, set your sound latency back to low or normal, setting very low is experimental, I believe, and may cause issues.

One thing you should do is set show FPS and make sure you're actually getting full FPS when the hangs occur, if not, it's probably your OpenGL settings.

Your device is powerful enough to play PS1 games easily at 720p or even 1080p native, but your native resolution is something like 50% larger than 1080p. One option may be to set opengl mode to reduced resolution at 800x600 and see if that changes anything, or use the 2x/4x HW renderer and see if it makes a difference (4x HW renderer should be identical to OpenGL, but not as hardware intensive at very high native resolutions. 2x is a compromise, but should perform without issues as well and still look very good).

Alternately, it's possible your tablet is throttling due to heat. Use something like TempMonitor to check your temps as you play and see how much it heats up. On paper and in benchmarks the Mali-T760 in the Tab S2 is extremely powerful, but I've been told anecdotally by a user here with hands on experience that the chipset is often downclocked due to heat, or throttles because of it, and doesn't get the same real world experience as it does in synthetic benchmarks.

I use this! 45 ° C good for sustain normal. As high as 65° C b beyond that wow! Set notification to preference.

It is normal for a phone to become hot. Your phone should be safe if if the battery is under 50°C (122°F).

I recommend TempMonitor for checking the temperature of your battery (and, optionally, CPU).

By the way, how did you phone not automatically lock whilst you were sleeping?
