Hello

 

I have owned this Samsung Galaxy A40 phone now for a year and this last week it has one time completely frozen and now it keeps on turning itself completely off, even if it is charging. Does someone know what to do?

 

Regards Sam

First try putting the phone in Safe Mode which disables any downloaded apps and leaves the stock ones working and then see what happens.

 

Check there are no software updates in your phones settings.

 

If it continues then if this was my situation I'd back up and factory reset.

 

If it continues still then seek support from a Samsung Experience Store  / Samsung Service Centre 

 

 

My advice comes from being a UK Samsung Phone Owner.
I have no affiliation with Samsung.

I have never heard of this problem before... As mentioned by BandOfBrothers, I suggest looking for some badly behaving apps. Try some free antivirus off the Play Store like Avast, and if that can't find anything, consider factory resetting. If the problem still comes up, go to Samsung support and see if they can offer you a replacement.

I have the same issue, the freezing, everything, even the period of time that I have had the phone is accurate.

Same with my wife's phone. Have you guys tried factory reset? It's suspicious that all the phones are +/- 1 year old.

Same here since about 2weeks back. Drives me nuts.

 

Factory reset did not work.

I also have the same problem: it started 12th of July 2020.

I might have an hardware issue, as it does not turn on unless I connect a charger to it for 1 minute, then disconnect the charger, waith another minute and then the phone starts.
