Sony Xperia M5 armed with a Mediatek MT6795 Helio X10 cpu with 3GB RAM,
16 GB of internal storage, micro-SD card expansion support,
is one of the best mid-range smartphone you can find in the the market today.
It's 21.2 MP front camera can rival that of many flagship smartphones.
But Sony Xperia M5 is not without flaw.

Users have been reporting that Sony Xperia M5 is experiencing sudden automatic shutdown.
And the phone cannot be turn on until it is connected to the usb port.
My personal experience with Sony Xperia M5 is as follows
8 Oct - bought Sony Xperia M5 from Singtel.
16,17,18 Oct - experience 3 shutdowns and phone need to be connected to usb power to switch on
22 Oct - sent in Sony for repair
5 Nov - Sony replace the faulty set with a brand new set
18 Nov - experience 1st automatic shutdown with the 2nd Sony Xperia M5
10 Dec - 2nd automatic shutdown with the 2nd Sony Xperia M5
I believe one possible way to prevent Sony Xperia M5 automatic shutdown is
settings => power management => uncheck "queue background data"
The above setting is what I set on the Xperia M5 which may prevent the automatic shutdown from happening too frequently.
29 Jan: Latest update. This is one of the best way to prevent automatic shutdown on Xperia M5.
Apparently, the shutdown happen when the phone was trying to connect to the network in area where the network signal is no good. e.g. in areas like lift, underground, tunnels, MRT, etc.
So one simple solution is to turn off the mobile data. Without mobile data, you cannot surf internet, use whatapp, wechat, line, etc. But you can still receive and made phone calls, receive and send SMS.
So the trick is to turn off mobile before u turn off the screen. then u can go mrt, lift or any other danger zone of poor signal. When you reach safely zone with strong signal or when u need to use your phone, u can turn the mobile data back on.
