New Samsung sch-430 won't shut off

I have 2 sgh-m919 galaxy s4 s from TMobile. Both phones were randomly showing the message "sim card not detected restart" and phone would reboot.. sometime would have to reboot 2 or 3 times before i was normal. I tried many of the net poste solutions including paper on sim card, clear cache, new battery etc. Nothing worked

This week i was ready to buy a new phone.. but was sure the phone wasnt the problem. I started deleteing apps one at a time and found the problem. It is GOOGLE MAPS !!! G0 into settings / more / application manager / slide over to all/ down to Maps /clear cache/ uninstall updates / force stop. Then turn off phone and restart. When you go to use maps or waze again when it asks for permission "decline" it will still work and you wont see the sim not detected restart message again.. Google the words google maps crash or reboots and see how many phones crash. Galaxy s4 happen to have the dialog box that makes it appear to be a hardware problem! Googles motto use to be "First do no harm" please reply if this works for you

Good luck!

With the battery installed, press and hold the power button down for at least 20 seconds to reset it.
check to see if the power button is stuck, pushed in...
Hope this helps!

if you let it dry but turned it back on and it still doesnt work chances are its fried and cant be saved.
most phone are held down by screws but the plastic actually snaps together. using a sharp probe or very small ended tool you can pry it open and snap it apary

bad battery, go and get replacement
