Android - System crash and reboot when wifi connection is established

Hi there. I am trying to figure out a wifi issue on Android which causes the system to be crashed and rebooted. When I have a wifi connection or even search for available networks, suddenly the system is restarted due to some reason. Is there anyone who can shed some light on how I can debug or solve the issue? here is the logcat output below.

I got this log file by this command.

logcat2.txt

.\adb.exe logcat -d > logcat2.txt

It seems that your device does not have installed or does not support Google Play Services.

Hi,javagoza Thanks for your reply. I just tried to install the google play store and services through adb push *.apk over usb connection. Those errors were caused by this reason. But before those errors, I had this wifi issue. even I couldn't install google services through wifi connection. Do you have an idea about how I can debug and reach the reason for this wifi issue? is this logcat enough to understand? I have no experience in Android and very less in Linux.

You do not give information about what device you are using or what version of Android the device is running. So it is difficult to be able to help you.

The three JVM restarts recorded in the log have been for exceptions for security reasons. I don't see anything related to the wifi hardware, I could be wrong.

Yes, I thought the same thing, I couldn't see any errors related to wifi hardware in the log file I shared above. that's why I thought that I may have looked at the wrong log file.

javagoza has just spent considerable time examining your log file, and for what it's worth, I examined it too. We are trying to help you, so why don't you help us, and provide the power supply detail requested? All signs so far (from what you have specified so far) suggest a supply issue. This might not be the case, but let us rule out the most likely causes, since with respect, I don't know your experience, and I'm not just going to trust that the power supply is fine, without examining the detail that you ought to be providing.

Sir, I totally understand your concerns and read many articles and comments on the form about the power supply. It is literally out of my concern. I am sure my power supply is enough and can provide enough current. I set max current 5A in the power supply even though I didn't see any current consumption over 1A. Here are some videos uploaded for you. please refer to it. https://photos.app.goo.gl/3CziXjkMVT84qW1g6 .I hope these pieces of evidence are enough for you to rule out the power supply issue too.

You could be experiencing a brownout. How accurate is that power supply, and what's the voltage drop by the time the supply gets to the board? If you're experiencing a brownout due to voltage drop, it doesn't necessarily matter that you've set your supply limit to 5A; you could set it to 500A and the problem would still occur. The Maaxboard might expect the supply voltage to be closer to 5.0V than normal USB devices, i.e. (say) 4.9 V may be insufficient. You might need to measure the supply at the Maaxboard itself (not at the power supply end) with a multimeter, under load.

I am pretty sure about my power supply accuracy. And I also thought about the voltage drop possibility and measured 4.96V over the header pins. that's fair enough. Here have a look at usb 5v-in and header 5V pins are connected each other directly

Here you go a log file, I think I have really a good catch about wifi issue.

it seems because of memory issues, So according to this log, what are your ideas about the issue?
