Press that button, then you will bring to answer Google accound username and password (Google Mail account).

  2. Hi Xperia M, at first I was very much delighted to own you as my android phone. But now you know what, I am 110% disappointed. After 3 months usage, my phone starts hanging. Ofcourse i downloaded some apps and scanned by AVG anti-virus. While texting, my screen got frozen. The screen lock button works but the touch screen did not respond. I even rebooted my phone by taking off the battery. still it did not work. Hopeless! I have to do master reset and lost all my downloaded apps. Now it seems fine though! Can you tell me, why my screen got frozen and what is the best remedy?

    • Hi, there are many applications at Google Play Store that may make our Sony Xperia M become problem because the applications is not always created with good code or maybe that applications itself are not compatible with some smartphone, then this problem could make problem like something you got. With 1GB RAM and dual-core processor should ok to run normal and compatible one with Sony Xperia M, please try to read the applications review for unpopular applications that you want to use before download to Sony Xperia M.

    • Hi, Sony Xperia M is the smartphone with Android operating system. We can add many applications from Google Play Store or also by using offline APK files. Some applications out there may make our smartphone become problem because the applications are not always compatible or maybe some popular applications can also get problem with specific versions update. That is we can not fully sure about what applications good or bad. The recommended way to prevent problem at Sony Xperia M or other Android smartphone are try do download only good review applications from Google Play Store, do not install with offline APK applications since it may more easy to bricks our phone with with not safe applications. You may also not install too many applications if you not use that, because many applications in the background also can make our smartphone become hang or stuck in some situations.

    Reply
    • Hi, we are not so sure about changing GSM Mode to WCDMA Proffered or WCDMA Only or GSM Only, some phone usually not act like that. We can change every time and usually the network going to be able connect automatically after wait less then 1 minutes because the Sony Xperia or Android phone need to disconnect first and then continue to reconnect again after it already changed the network mode. If still curious about it, you can try to do hard reset to make everything back from the beginning and try to change the network mode and see what happen. If the problem still happen after doing hard reset, maybe you need to consult to official Sony service center.

      Btw, instead off doing soft reset your Sony Xperia M when your phone not get network after changing the network mode, you can try to do Flight Mode enable, wait for awhile and then try to turn off the Flight Mode, hopefully the signal will be back again.

    Reply
    • Hi, if you already sure the sim card is fine, try to see your phone data network is active from Menu Setting > Wireless & Network > Mobile network > Data enabled. Also make sure you are not in the flight mode. Other alternative you need to check is APN setting. Consult with you network provider to make sure the APN is not wrong. If everything is correct in you Sony Xperia M but the phone still can not access Internet, then you may try to perform hard reset or master format to clean all setting to factory default and also clean other installed application which may make your internet can not work properly.

    • Hi, usually if the security password only work when you turn on the phone, then it should be Simcard Pin Lock. Try to remove the SIM card lock by go to Setting Menu > Security > Sim card lock at your Sony Xperia M. You will have to deactivate the SIM card lock protection at this locations. Sim card lock is different with screen security protection. The screen security protection will active anytime (depend on how long time the screen lock will active) when we wake up or open the screen.

So you will be get double actions using PC Companion update and hard reset.

If you never make your Sony Xperia M at flight mode, then you still can use or borrow any other GSM card which already active with Internet, then follow again the steps to recover forgotten password using Google account. If you still can not access the Internet, then the only way you can do is doing hard reset or master format using hardware button #Option 3 or using PC Companion at #Option 4.

    • Hi, as far as we know, Sony Xperia M phone does not have any default encryption options. Maybe you have been installing 3th party applications to encrypt the storage for security reasons. If your problem comes from that 3th party applications, then you should do hard reset or master format to reinstall and remove all applications and reinstall back to factory default setting and applications. You can choose 2 ways to hard reset, using hardware button key at #Option 3 or using PC Companion with computer with Microsoft Windows operaing system like #Option 4 above.

    • Hi, please make sure your battery is fully charger, you can try to charge with different Android charger. If you battery has already charged, then you need to try doing hard reset with hardware button. Otherwise, maybe the hardware of your Sony Xperia M is hard brick, then you need to bring to Sony service center for further test,

    • Hi, if your Sony Xperia M Dual get problems with sim locked, the you can try to use different simcard to access your phone. Or remote the simcard and try to turn ON and access your phone. If the phone still locked then maybe the problems came from security screen lock protection. If this is the problem, then you should have to try doing hard reset using hardware button. If you still get trouble with your Sony Xperia M but you can not find the solutions, we suggest you for ask help at Sony authorize service center.

    • Hi, sorry we do not have the information about OS that installed or the latest update for Sony Xperia M. However, you does not need to always update to latest firmware, as long as you are already fine and fit with your current operating system or firmware. Usually some minor update will give security or bug fix for several trouble, but some users does not get trouble or they does not feel about the bugs. The Major update will change the operating system or firmware version.

    I am using sony Xperia M c1904. This updatedo 4.3 build number 15.4.a.1.9 but again asking same build number 15.4.a.1.9. Why asking same update after updated

    Reply
    • Hi, usually after update with OTA (over the air), it will only ask to update again if there are newer version of firmware. However, maybe there is something that we don’t understand about the version number or not finish update maybe (just in case). You could just try to do the OTA update again to make sure you will finish with that 15.4.a.1.9 version at your Sony Xperia M.

    • Hi, it seems that your Sony Xperia M has already installed with some applications like anti-steal applications or something like that. We suggest you to totally reformat or hard reset your Sony Xperia M to clean up all applications. If you still get problem when doing hard reset using software menu, then you can try to do hard reset using hardware button combination key or with PC Companion. Please follow either #Option 3 or #Option 4 above. Both steps will not ask any password protection while doing hard reset, but please remember, all data and installed applications will be removed or wiped from your phone.

  38. Hi
    It’s possible to take all data (e.g. SMS, Whats app, etc.) backup and restore for Xperia M Dual ( C 2004)
    If possible, how can do it?

    Reply
    • Hi, at standard Sony Xperia M without root, for some applications, we can do backup for data and move to other phone. In your case, you can move SMS using applications SMS Backup Restore which need to download from Google Play Store, after that we can copy backup data to external drive. At new phone you need to install the same applications SMS Backup Restore from Google Play Store and use the same data from old phone to restore using this applications, then all your old SMS will be available or restored at new phone. This is also happen at Whatsapp backup, because automatically every 4 AM Whatsapp will do backup. This is the steps, follow it steps by steps, please move all Whatsapp folders from old Phone to new Android Phone using MicroSD card or using USB cable via your computer, after all Whatsapp folder moved, then you can activate your same Whatsapp account but like usual, it will need to use the same phone number (or wait sms notification if you are use different number), once your Whatsapp account activated, then Whatsapp will automatically find the backup files and give options for restore all chatting history to new phone.

    • Hi, we never do encrypted for Sony Xperia M, but some users have trouble with the encryption when their phone hang or turn off because battery empty capacity that make it off. If the encryption stop in the middle of process, then all of your data at Sony Xperia M will be unreadable or corrupt, in this case you have to reformat your phone to make it work again.

    • Hi, please try to download any other 3th party camera applications from Google Play Store like Google Camera or Camera 360. There are all free camera and can test your camera hardware. If your problem comes from build in camera applications, then it can be finish to force it work again with that new 3th applications camera. If all applications camera still can not work, then you should try to do hard reset to reinstall the operating system to factory default. If you camera still get the same problems, then you hardware problems may get trouble and need to get repair.

    • Hi, sorry reply in English, it seems that you have forgot the password for encryption Sony Xperia M. Basic idea to encrypt internal storage is because you would like to secure all data inside this phone to prevent unauthorized people get your confidential data. But because this encryption is too strong, then we can not recover if we forgot the answer for encrypt answer. You just have to hard reset your Sony Xperia M using hardware button combination key, or please use PC Companion which need to downlaod from Sony official website and do hard reset with steps at #Option 4 above.
