    • Hi, basically by doing hard reset, your Lenovo S820 will be reinstall with the clean and factory default operating system or firmware, the phone will run normal again without any problem, unless your Lenovo S820 have hardware problem. Other possibility is maybe you every change the firmware into non standard or non official version, then it may happen like that or not working properly. So, first make sure you use the official firmware, if the problem still happen, bring your Lenovo smartphone to Lenovo service center to test the hardware conditions.

Please try to see at camera setting and try to saved on external card. You can also use some 3th party applications which can download from Google Play Store, that camera applications also have save to external card setting.

They should try for a day or more to make sure the problem not happen again.

    Reply
    • Hi, basically there are no different between Lenovo S820 with 8GB vs 16GB internal memory for the software. But you can try to check for the version of yours compare with your friend’s Lenovo. If everything at the same versions, you should try to do hard reset to reset all setting to default and refresh all installed applications with factory default only. After than you can try to test you phone again for speed and everything. Please note, this suggestion only available if your friend’s Lenovo also at standard conditions without root and use same operating system versions.

    Reply
    • Hi, if your phone running slow after run in some period of time, then we suspect your trouble come from the applications. Some user have problem to find which applications that make this problems. But you can try to find out first from Menu Setting > Apps > Downloaded. If you can not find that applications either, then you should consider to do hard reset or master format to make your applications back to default again. Try to run test for ensure that the speed already back to faster again using default applications. Hard reset also recommended to do after we do update for firmware at our Lenovo S820, especially when we feel the phone not working properly after doing update.

    • Hi, moving picture from Lenovo S820 is the same steps as you move other files to another folder. You can use default File Manager at your phone, or you can try 3th party file manager from Google Play Store like ES File Manager or something similar that. Open the file manager, browse / choose DCIM folder, because all default camera images or pictures saved at DCIM folder. Then you can Copy and Paste to other Folder / Album that you create.

    • Hi, please make sure your Lenovo S820 language at keyboard setting already setup to English, do not activate any Chinese options. The other alternative you can do, try to download 3th party keyboard from Google Play Store, some of them that you can try have name: Go Keyboard or Smart Keyboard, most of them free although some free keyboard have disable some more options, but using free keyboard to replace default keyboard still have some benefit, including your automatic Chinese character when you write phone book.

    Reply
    • Hi, this problem seems because the LENOVO S820 video recording bitrate is not too high. Therefore you can not move to fast while recording video using this camera. This situations not only happen at Lenovo S820 camera, but will happen to some brands when the minimum specification can not fit to video recording. As we know phone camera only suitable for support our daily activity while we are not bring real camera or video recording, but if you really need good camera or video recording result, then you need to consider buy or use real dedicated camera or video gadgets.

    • Hi, try to do carefully. Turn off your Lenovo S820, try to go to recovery mode by press button:

If I try to take photos, it freezes and shows a message ” lenovo camera and gallery is not responding. Do you want to close it now?” Sometimes it seemed that the picture had been taken .but nothing was added to the gallery.

    • Hi, there are some tutorial at other community to make the Lenovo S820 camera become better then upgrade to latest Super Camera firmware. As far as we know, using this facility should root your phone and flash it with recovery tools. Some problems happen because doing root itself will make your phone become trouble for some situations. The super camera tools also can make crash and make the camera not work properly at some versions. Therefore please make sure you are use the factory default version to make your Lenovo S820 functions work properly. You can also try to download any other 3th party camera from Google Play Store to test weather your camera work or not. If still not work, try to do hard reset and test again the camera.

      • Hi, can you tell us how you flash your Lenovo S820. Basically the factory default upgrade from Lenovo comes from OTA (Over The Air) update for fix some bug at the operating system. Maybe you are talking to flash use 3th prarty custom ROM from other community. Unfortunately the custom ROM upgrade can not fix with standard operation that usually we know. So, you need to try or ask some help from that community if some trouble happen within the steps.

    • Hi, please make sure your power charger work properly. Try to use different Android charger to charge your Lenovo S820. If still not work, then please make sure the battery also still alive or work by test with avo meter or use different battery if available. If the phone still not turning on although you already test it with hardware button key for reset, then maybe your Lenovo S820 get hard bricks. Therefore, you have to bring it to nearest Lenovo service center for further test.

    • Hi, sometime doing upgrade also will make our important data wiped or removed from our phone. Therefore we suggest to do backup before doing upgrade or hard reset, also at Lenovo S820. Unfortunately data at internal memory will not easily recover once they has gone. Although you can try to use some recovery applications from Google Play Store, but sometime they can not help to recover it.

      Reply
    • Hi, you should download important applications at your Lenovo S820, but please remember, Lenovo S820 only have 4GB internal memory, some memory will use to save the source file of operating system and also same space to save cache. You will get warning or trouble to download if your free memory left is around 150-200MB. The update process from Google Play Store will be trouble and sometime the icon at status bar above display will show always download and not finish. Please try to remove or uninstall not important applications, then make sure the internal memory free space is more that 400MB, it will make your phone work normally.

Basically this is fine for running several applications for multitasking, but if you have many applications run together which some of them as background process then, the RAM will be limited as well, and will run more slowly because your Lenovo S820 need to make sure which applications can automatically stop to serve new other application for run as foreground.

Unfortunately the microSD external card only can use to save some other files like camera (after change the options), downloaded files and other external data like movie or music or pictures copy from other sources.

I need to do a hard reboot and restart just to unlock the screen, and the touch screen works properly in general. Is this a firmware problem? I don’t think there is a problem in its hardware.
    Could you please help me on this matter? Thanks.

    • Hi, if you have trouble at your Lenovo S820 after upgrade to Kitkat, then some problems can be solve after doing hard reset or master format. Sometime some old applications or some setting from previous operating system may crash or conflict at new firmware, therefore you have to try doing reformat or hard reset after finish upgrade to new updated firmware.

    • Hi, usually you can not remove or uninstall Google Play Store at standard non rooted Lenovo S820. However, if you have rooted and there are some bad possibility that can be happen with your system apps. You may also try to download other 3th party Android Play Store like SlideME or something similar like that.

    • Hi, if you can not unlock the screen lock pattern, then you have to do hard reset using hardware button combination key. But please try to unlock or bypass forgotten security protection using Google account that you have signed in before. Please try to give wrong answer continuously until phone locked / freeze 30 seconds, find Forgot Pattern button and give the Google account at shown field.

    • Hi, there are two possibility that you can try. First, try to download 3th party camera applications from Google Play Store like Google camera or something similar like that, then you can try to use it for take pictures from your Lenovo S820 camera hardware. If the 3th party camera applications also not work, then you have to try doing hard reset, because some previous firmware applications may conflict with new firmware.

    • Hi, basically you can not downgrade your Lenovo S820 using OTA like you have done for upgrade. if your phone already have Android Kitkat but some problems happen, then please try to do hard reset, because maybe some installed applications are not compatible with new operating system version. If you do hard reset, all data and installed applications will be removed and you can download new version of that applications which may compatible with Kitkat from Google Play Store.

    • Hi, have you ever to install any 3th party home launcher? If yes, please uninstall it first. Sometime wrong setting with additional home launcher will can make navigation button not work properly. You also uninstall some other 3th party tweak applications. If you home button still can not work, then you have to do hard reset or reformat, but this steps will make your important data and installed applications wipe or remove. After hard reset your Lenovo S820, you have to re-setup again from beginning including install important applications that you need to use.

        • Hi, perhaps you have cloud backups for previous setting. Please try to do hard reset again until your Lenovo S820 phone back to factory default setting with default applications. After start again from beginning, please do not login to any Google account, because at some case, this steps will restore back all cloud back setting include installed applications back to your Lenovo S820 and old previous apps will not compatible with latest updated firmware or operating system. Please wait, if after several time your phone work normal, then maybe you already get the solutions. Just try to login again, but please choose do not restore or backup anything from Google account.

          You also can try to download any 3th party launcher like ADW Launcher or something similar like that, these apps are free download from Google Play Store, hopefully this is also can solved your problems.

  32. Hi. I have a lenovi 820 s but from some days i cannot install apps cause it gives an error. Not enough space. It has a lot of space on both internal and sd card. Please help me with a reply

    • Hi, it seems that your internal memory system files maybe already full, because as we know the internal memory for Lenovo S820 is very limited. Please try to reset data for Facebook or Tweeter or uninstall some applications, then try to install other applications. If everything work, then you need to uninstall not use applications to give more free space at your internal memory system files.

  33. I had my lenovo S820. The problem is that my front camera had stopped working from long time. Tried all updates on the phone but of no use. Can anybody resolve the said issue of mine.

    Reply
    • Hi, first you can try to download 3th party camera applications from Google Play Store for test weather this problems come from hardware or software. If your front camera still not work properly then the other alternative if doing hard reset or master format using steps above. Please backup all important data before doing hard reset, because all data will be wipe or remove after doing hard reset. If this problems come from software or firmware, doing hard reset will reinstall clean factory default Android operating system at your Lenovo S820, and hopefully your front camera can work again. If you still can not use front camera after doing hard reset, then you front camera must be broken and have to fix at Lenovo authorize service center.

    • Hi, there are some possibilities that can make your phone get this problems. We suggest to do hard reset using hardware button combination key because your Lenovo S820 operating system seems damaged or corrupted. This process will reinstall or recover or reformat Lenovo S820 factory default operating system, but all data or photo or video will remove or wipe or deleted from your phone.

    • Hi, as far as we know that Lenovo S820 can work at GSM network with frequency 900 Mhz or 1800 Mhz or 1900 Mhz, therefore for your Celcom GSM card which use 900 Mhz and 1800 Mhz should work normally. We suggest you to go to Celcom provider, and ask weather your phone can use other Celcom simcard at customer service. You can also try to hard reset or reformat your Lenovo S820 to reset all setting at factory default.
