my iphone 3gs goes haywire and reboot itself every minute when i let it ran out of battery or simply turn it off and on it back..
it goes back to normal when i reset all settings and as long as i dont let the phone ran out of juice or off it
any idea what is wrong?

Hi,
my iphonex losing connection once in a while even with my 4g at 2 bars
i have no clue what triggers it until i tried to whatsapp and it shows no connection.
Noticed the bottom right dictation symbol on the keyboard when i try to type will be blinking and when i open siri, the message of siri not available sign will be blinking up and down
here is the screenshot, cant get another phone for video
