I have random restarts on my Galaxy A32 5G (T Mobile). Running it stock. No mods at all.

Sometimes they get bad and basically boot loop the phone for a while before it stabilizes.

I am sure it's software because a factory reset fixed it for 8 days. Ran flawlessly. Then the problem came back. I have to think if it was hardware that this wouldn't have helped.

I think it's something corrupted in the stock ROM because the problem occurred when I booted to safe mode with only system files running.

Can I reflash the stock ROM in ODIN without the bootloader being unlocked? I know you can't do that if you are changing the partition. But I'm not sure if overwriting it with the same partition info counts as changing it. What about downgrading to the previous build? It's been a few years since I modded a phone. I am starting to forget the rules.

I'm open to other suggestions as well. Specifically what happens is the data connection doesn't work suddenly. Websites load to "Sorry, you are offline" errors. Then apps won't open at all. Or they force close immediately (All apps. CAn't even load settings) Then the phone shuts off (doesn't power down, just goes to black as if a thermal protection was triggered) And it reboots. Then it will repeat this process for an hour or two just boot looping and force shutting down until eventually it will boot properly and be somewhat stable for a day or two.

Any thoughts?

I tried the basic stuff. I freed up internal memory. I factory reset it. I cleared the cache is the bootloader and did the repair apps function. I uninstalled everything I could live without for a few days. The problem seems random. It's not when using a certain app. ONce in a while it'll do it just being in my pocket.

I did notice that the Opera Browser comments on Google Play have a bunch of people complaining that the apps doesn't work with their A32 phones and causes shut downs. I don't think it's the Operar Browser because I had the shut down in Safe Mode. But other people seem to be having the issue.

Start in safe mode, if runs ok it was something you installed. You are what you load...
Did that. Still got a random restart in safe mode.

I still think it's software. I just think it's a corrupted system file. Hence wanting to redo the system ROM.

I have no idea how to identify and isolate a system file in a non rooted phone.

It's possible. That's a serious problem. Is there a memory leak showing? Any resent updates?
Try a factory reset but don't load anything.

How can I check on a memory leak? I used to know how to do that on a rooted rom. But on a stock one....none of the fun apps I used to use work

Nothing looks weird right now in memory.

I will jump right to that the next time it starts a ring funky and see if something looks wrong then.

The real question is if I can reflash the stock rom using Odin when my bootloader is NOT unlocked.

If there is a corrupted system file that should fix it. But with the bootloader locked I don't know if trying that will brick it.

If only there was a new update coming soon that with OTA fix it...

Stock version is ok to flash... unless it powers off during the flash.
A Samsung Experience center at best buy can do reflashes and allegedly have advanced diagnostic tools.

One way corruption can occur. If it flips a critical bit of data it can cause real mischief. There is no damage however to the hardware. I keep my phone far away from any ionizing radiation sources ie X-rays, CATs etc. because of this. The energy potential is probably too low but it may occasionally be enough to cause a SEU.

I'm getting a Serious software issue detected on start up.

I reflashed the stock rom....same one I had. And the issue persists. The reboots persist.

When it gets bad no apps open. Every app will force close on launch. Then it reboots. Ussually stuck in a boot/force reboot loop for 10-15 minutes until it finally loads stable. Then it might be good for a minute. Then it'll restart the loop.

Reflashing the stock rom didn't fix it. Next I'm going to try to downgrade it to the previous build. I don't know if I can even do that with a locked bootloaded but we'll see.
