Try to reflash firmware with odin

There is no more Flash Player for Android and there won't be another. Android is no longer compatible with Flash Player. Playing Flash content is very processor consumptive and it drains your battery, also shortening the life of it. Android (Google) recommends using either "Dolphin" or "Puffin" as your browser if you need to view Flash content with a mobile device running Android. They're both available in the GooglePlay store. These browsers use "server side" rendering to reduce the load on your device.

Check the connection from the DVR to the router. You may need to reset the router.

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!
