My Samsung phone will switch itself off randomly, there is no relation to time nor battery level.
I have had the software upgraded and also the battery replaced and the same problem still exists.
The mobile shop phone came from wont help as i cant "replicate" the fault on demand.
HAs anyone else come up with this problem or a soloution?
I have been to the vodophone shop and they tell me that the phone is off when closed i agree you cant see anything when its closed but i think its a novel idea means you dont miss an inportant call.
All is revealed once the phone is opened the battery lasts for ages so i dont see this as a problem.
Yeah i had same proble on e250 but it was when screen light went off it switched off but after visiting 1st carphone warehouse 2 days after purchase told no manager in to do exchange, went to secound shop told none in stock went to 3 rd store told no stock left sent back to 2nd store told they was showing 3 went back they found them but told they wont exchange because i could not show them fault went to 4th store where purchased from where i was told by customer care had 90 in stock told me they was out of stock ask them to ring customer care they said no need as they need to see fault so i said i would sit in there store until they saw the fault so i asked for a seat which they could not give due to insurance purpuses !!! so i stood in front of guys desk for about 9 min then he said he would exchange the handset joy!!!!!
thought that would be end of that but no now the replacement handset switches off when it wants mid call whilst on standby whe it feel guess i have to stand in carephone warehouse all day this time

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
Try updating the software. Start by backing up anything you wish to keep like media or special messages and then update to next version of software. Where the software is up to date, cgeck online for reports of similare cases with thos happening for any other people with the same model or software version. Failing that it could be the connecters in the phone that are faulty that rattling the phone round a random way would cause the battery separate from the connecters and cause this to happen. Your service provider should be able to tell you straight away if there is a warranty that can cover the phone for a service to correct this issue.
The phone has hung up because there are errors in the software. So to reset remove the battery and the memory card from the phone. Using your PC , scan the memory card for any corrupt files or media files with virus- it is possible when they are downloaded from unsafe sites. If so remove or format the card. Now replace the card and battery and switch on the phone. If the phone hangs up then it is confirmed that the software is corrupt and will need a reinstallation. Seeking help from the authorized service /support centre is most ideal. Take estimate and decide.
OK, the fact that the phone keeps restarting or switching off, is either an overheating issue, or, most probably a firmware related error. You will be able to get the firmware updated at your nearest brand service centre.
If the firmware update does not work, it is an overheating error.
Feel free to let me know if you need any further assistance.
