   • Hi, Android have simple step if you have forgotten security password protection. Please find Forget Password button. If you can not find that button, you need to unhide it by answering wrong security answer continuously until the phone frozen and the Forget Password button will be appear. Press that button, then you will bring to answer Google accound username and password (Google Mail account).

       • Hi, if you forgot the security pin for Sony Xperia M, then you can try to bypass using Google account, please give several time wrong pin answer continuously until your phone locked or freeze about 30 seconds, at this time you will find Forgot Password button, press this button, then you can give your Gmail username and password that you have signed in before. If you still can not bypass your pin using Google account, then you have to force hard reset using hardware button combination key or using PC Companion like steps to hard reset above.

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.

   • 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.

7. My internet is not working on my sony xperia m dual. I think there is some problem with the handset as,it works on the other mobiles.what can i do? I have tried rebooting it as well

   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.

There are some option to Root your phone, but since we are never recommended to root, then we can not give advice how to unroot your phone.

   • Hi, you have to make sure about the LCD hardware at Sony Xperia M. Please try to reboot or soft reset your phone, then if you can see the Sony logo at startup boot, then your LCD hardware should be fine. The problem maybe comes from your applications that block the display screen. In this case you should try to do hard reset or master format. The other probability if you can not see Sony logo at startup boot, then the problem should be come from your hardware, and need to bring to authorize Sony service center.

The instructions are available above. But if your phone still can work and you can access Setting menu, then using Option #1 to Hard Reset with Software menu are very recommended.

        Reply

        • Hi, the security protection can be bypass or unlock using Google account or Gmail account. Please remember the Gmail that you have already Sign-in when the first time using Sony Xperia M. That Gmail account use to synchronize our Android data to Google server. That Gmail account can be use to bypass forgotten security protection password or pattern. Please try to give several time wrong answer for your security lock, after about 5 times wrong answer continuously, your Sony Xperia M will be temporary locked or freeze about 30 seconds. At this time, you will find Forgot Password / Pattern button. Press this button, then you will be ask for Gmail username and password (the same account with the first time sign-in at this Android). That Gmail account will unlock or bypass your forgot answer.

          How about if you can not access Gmail account for bypass or unlock forgotten security protection? Please make sure your Internet connection active when we need to bypass the forgotten security protection. If still can not access, the you should do hard reset with step at Option #3 or #4.

Then I updated my phone using pc companion as told by cc guys , still the result is same.There is no problem with the 2g but how can fix my 3g without getting hanged up…..please help me..I need ur suggestions ASAP

    Reply

    • Hi, by default your phone will work normally with 2G or 3G. Although we setup the Sony Xperia M setting for 2G only or 3G only, the phone should not hang. Try to change the simcard with other working one. You also should consider to do hard reset if the problem still happen.

    • 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.

    • Hi, there are several options that you can do to perform hard reset at your Sony Xperia M C1904. If because of any reasons you can not access recovery menu with hardware button, then follow the options #4 above to hard reset Sony Xperia M using PC Companion. The conditions that you need to prepare while doing hard reset or factory format using PC Companion is a computer with Internet connection and also USB cable. Why hard reset Sony Xperia M using PC Companion is recommended? As we know some user maybe have problems to do hard reset using hardware button while Sony Xperia M get soft bricks or not work properly, as the PC Companion using Internet connection at our computer also try to update the latest Android OS or firmware which will be automatically update to our Sony Xperia M. So you will be get double actions using PC Companion update and hard reset.

    • Hi, unfortunately you only can recover forgotten security password using Gmail account should use Internet data connection, so the phone can received and get response from Google server. 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, this is serious problem when doing flashing or writing the firmware but interrupted because of power computer trouble. We just worry your phone stuck and can not use anymore without help of Sony authorize service center. Therefore we always write to always charge our phone before flashing, but also we never predict or get in this situations that computer restart by itself because of upgrade firmware. Usually just because power failure when flashing with PC computer without UPS, but the solutions when the phone bricks then we should ask help for Sony service center.

    • Hi, maybe some applications can make your soft button become trouble. Do not worry, at first steps you can try to restore all to factory default setting using hard reset or master format. We think that your Sony Xperia M still can access to Setting menu, then please follow the steps at #Option 1 above. Otherwise you also can do hard reset using hardware button like the steps at #Option 3. But please remember, doing hard reset or master format (with any options) will remove or wipe all important data and installed applications at your Sony Xperia M, therefore better you do backup first before performing hard reset.

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.

    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.

We can not make sure what kind of software that previously installed before you change the simcard. However, you may try to do hard reset using hardware button combination key like steps at #Option 3 above or use PC Companion for reformat the Android operating system using computer with Microsoft Windows operating system (Win XP/Win 7/Win 8+).

    • Hi, do not worry to do hard reset to factory default after doing upgrade to Jelly Bean 4.3, because your Sony Xperia M file source of operating system has already upgraded as well to Jelly Bean 4.3 which has safely saved inside your phone ROM, therefore if you do hard reset or reformat, then your Sony Xperia M will still get latest upgraded Jelly Bean 4.3.

42. Hi…I have a XperiaM C1904 model. IOS is 4.3. I changed the sim card and after that every time when I am trying to unlock the screen it is asking security password. And also it is sending one sms saying ‘ Sim card has been changed on 99xxxyyyyz’ when the phone is restarting. It is also not identifying the number I.e. Phone number. Actually I ported my sim and it should show same as previous but it is showing unknown. I have given 10 times wrong password to find forgot password button. But got nithing. Luckily this is same as my Gmail password. But I want to stop this nuisance. Please help..

    • 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.

    • Hi, the easy steps to hard reset or reinstall the clean factory default Android latest operating system using PC Companion is recommended. If your computer can not detect the USB connection, we suggest you to download the Sony Xperia driver from http://developer.sonymobile.com/downloads/drivers/. Please choose the correct driver, some similar Sony Xperia type have the same driver to use. Please make sure your Internet connection active while performing reinstall using PC Companion.

    • Hi, updating firmware basically have to run 2 steps, first is downloading the formware which is need some time and good Internet connections, after that the process will continue to installing the firmware, usually all process need some times, therefore we always suggest to connect the charger while updating. However, you still can try to update using PC Companion and connect it after press volume button if the PC Companion ask that. Please follow the steps at #Option 4 above.

47. 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.

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.

    y me aparece apenas lo prendo “type password to decrypt storage” y no lo puedo desbloquiar, la computadora con el usb no lo reconoce y tampoco me entra al menu presionando (apagar y subir el volumen) que hago?

    • 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.
