Opening the back cover of Xperia go would be a bit tricky. Whether you would be easily open the cover or got some problem on opening the casing depend on your "hand with its finger". On the bottom-left of the back cover, there is a strap hole in there. This strap hole also has another function for opening the back cover case. This strap hole is the first start as a opening key of the cover. Here the tips for you to open the cover.

Eject Card holder, Insert SIM Card on Sony Xperia Go ST27i / ST27a

After you removed the back cover case, now you can insert your SIM card. The Sony Xperia go uses standard SIM card type, but you can't directly insert the SIM card to its card slot. It's because the card need  to be placed first on its SIM card holder (card tray). Therefore to be able to insert the SIM card, you had to eject the card holder from its slot. With your fingernail (forefinger) pull out the SIM card holder from its slot. The card holder slot provide on the left side of the phone (from front panel view, see the image to make sure where the location of this card holder slot).

To insert the microSD memory card, you need to open the back cover casing (just like on SIM card), but at this time, even though you had removed / opened the cover, there is an additional protection on the external memory card slot. It has a special cover. This microSD card slot cover is applied to attain the IP67 certificate on dust and water proof. With the Xperia go rear panel facing up, you can find the location of this microSD slot with its cover on the top-right side of the phone (picture).

Then you are ready to insert your memory card (up to 32GB capacity).

Doing Hard Reset aka Factory Reset on Sony Xperia go ST27i / ST27a and Charge the battery.


If you owned this 3.5 inches phone for the first time and you wanna turn the phone on (by pressing the power button until it vibrates) for the first time after you had been assembled all the part (SIM, microSD memory, and else), you need to charge for at least 30 minutes the battery of this Xperia go. FYI, the battery is unremovable and replaceable type. This must be one of the reason to acquire the IP67 certificate. That is why there is no tutorial on removing and assembling the battery for this device. It uses Li-ion type with 1305 mAh capacity.

To charge the phone all you need to do is connecting the microUSB port with your phone. The USB port for charge had a cover that you need to open first. Use your finger nail to open it. On the other end of USB plug the USB port into Power Adapter then finally plug the Adapter into Power Electricity Source in your Home. Done. Otherwise, you can directly connect the USB cable into Personal Computer. Though, we not recommend this charging option if it purposely for the first time of battery charging. It may take a little longer than via Power Adapter.

To do Factory Reset aka Hard Reset all you had to do just Go to Settings > Tab Privacy > Tap Factory data reset > Reset phone > Erase everything. But, in case you just wanna reboot / restart the phone, you can follow this key hardware combination: Press and Hold the Volume button and Power button at the same time, then release it whenever the phone vibrate. This action sometime also called as Soft Reset.

In case you phone stop responding or touchscreen is frozen, you can turn off the phone by Holding and pressing the Power button for about 11 seconds, then wait until the phone vibrates 3 (three) times, and release the key. That would shut down the phone automatically: forced shutdown. If the freezing problem frequently occurred, you can do Factory Reset, but make sure all you data got saved first (back up needed).
