iphone weather app gives incorrect temperature

After the IOS update it could happen to get some errors on the weather app and receive other data than what's in reality ...the solution might be to remove and install again the weather app.

My samsung phone wont turn on

Try this:

1. remove the existing battery.

2. install a new battery.

3. Turn on your phone.

It might happened because you've used the phone too much and the battery got drained!
After your phone turned on again, you can recharged the old battery again and can use it on your phone. Seems like the Samsung phone does not recognized a drain out battery.
