Hi guys, I am in great trouble. I have a Sony Erickson Xperia ray and recently all the contacts have disappeared from it and I really need help. Is it possible to the contacts? I had a lot of important contacts in there…  Please help me! 

I have a smartphone powered by Android 4.4 Kitkat and my boy deleted all the contacts on the phone and I'm having a hard time talking to my friends. Is there a way I can regain my contacts back on Android 4.4. If yes, how? If no, is this feature added in the latest Android OS?

I really need an application which can produce a very sharp sound. I have many things to do with the sound but for now, I want only the source of sound. I'm looking for such an application which can produce very shrill sound as a ringtone. Is there any solution for me?

I have installed Airport City on my Android and it is not working properly. When I click on the icon of the game, I get a low memory message on the lower left corner of my screen. I'm on Android 4.1.2 with 512MB RAM. I meet the requirements of the game but it is not working fine. I get the low memory message while using other application too and sometimes, my tablet even restarts. How can I fix this error?

I have Windows 8 tablet and I have Netflix app installed on it. The app worked fine few days ago but it is not working these days. When I touch the app icon, the app starts and a white dot circle appears. It loads as usual. But it loads forever. I have left it to load for about 3 hours now but it is not working. How can I fix this error?

P.S I have the latest version.

I'm getting a lot of notifications on Android these days because I have installed a lot of applications on my device. My smartphone runs on Android 4.4 Kitkat. How can I turn off the notifications in Android 4.4 Kitkat? Will the RAM get freed if notifications don't come time and again?

I no longer see my photographs in my Samsung Galaxy S5. I do not know if my kid deleted them while playing games or not. Right now, I just want to recover them since they are of very special moments in my life. Can you help me please?

Yesterday I forgot to bring my car key and it made me think of an idea. I have a fairly recent car and most of the locking and on-board mechanics is based on an integrated computer. I was wondering if it is possible to use my mobile phone to unlock my car. What would be necessary?

I am a fan of the viber free messaging service on mobile and recently while using the app, I noticed that there is a desktop version. I was wondering how it works because in the phone the viber software uses the sim phone number as the base for transmission but on desktop how will it work?

I just got to upgrade my camera app on my phone and noticed a new shooting mode. To be precise, I am speaking of my mobile phone which operates on android. The feature I am talking about is the 360 sphere that google has put forward lately. When I try to take pictures with it, it comes out all blurry. Is my phone broke or is it the app?
