    • Hi, as far as we know, go Keyboard only replace the theme. layout or display of default keyboard. The working procedure still the same. If you use standard qwerty keyboard then it will work the same for all 3th party keyboard. Pressing A will result A and etc. Unless you use Go Keyboard for special character like Chinese or Korean. You can try to uninstall Go Keyboard to see weather the standard keyboard can work with your password pin. You can try to unlock or bypass your security protection using Google account. For input Google account, we are sure it will work with standard keyboard.

  7. Hey? My phone keeps on telling me memory full and when I delete some applications still have the same problem and My photos misbehave when I open them. What might be the problem? Please help.

    Reply
    • Hi, all applications that we install from Google Play Store by default will use internal memory to keep applications and data files. If your Sony Xperia Z1 does not have microSD card, then all photos and movies that recorded or capture with Honami camera will also saved inside internal memory. Although we already uninstall some applications, but some applications like Facebook and Twitter will always keep data and cache inside internal memory and sometime this size will increase when we active in this social media. Please try to check it from Setting > Apps > choose All tab and wait several seconds until all applications refresh and show how many MB use at your Sony Xperia Z1. Try to find FACEBOOK application and you will see the file size, choose FACEBOOK and try to press Clear data and Clear cache button. Then your internal memory will increase some free size. This is only example that some apps will use internal memory space to keep their data, please try to find other applications. About your photo misbehave, please try again after remove some not use applications and remove data files, after that restart or reboot or soft reset to see if your phone will work normally.

  11. I’m having two (probably related) problems with my touchscreen. First, it is intermittently unresponsive. And second, when I touch an icon (e.g., facebook) a different app appears (e.g., google maps). Using messenger is sometimes impossible because it enters different letters than I touch (e.g., I touch the letter “n” and it enters the letter “q”), or it simply starts entering a series of random letters. Has anyone else had this problem, and if so, is there a way to correct it without sending it in for costly repairs? Thanks.
