My Xperia M4 Aqua keeps turning on and off

[Ptolemy]

Only 6 months old and I have not done anything I know of to cause this issue
Basically it gets to the sony screen after turning on and turns off automatically before doing it again regardless of whether I have touched it or not, It seems like some sort of loop but will Ocassionally turn on. I have tried a factory reset one of the times it has turned on and that did not change anything and i dont seem to be able to access the recovery mode.

Anyway if i could get some help on how to fix this ASAP it would be nice

Thanks

You should contact Sony Xperia support.

Do you experience the same reboot if you remove the SIM card?

[Ptolemy]

Yeah i was going too but they are not open for the weekend so i was just seeing if anyone here could help!

[Ptolemy]

And yes, same problem when sim card is out as well as memory card

If the phone doesn't work without the SIM and SD cards nor after repairing the phone with PCC, then it might be a hardware issue

[Ptolemy]

The Pc will not connect to it properly when it is off either so i can not do that

@Ptolemy

Contact your Local support to get it inspected.
