I am using Lava Iris and it is working fine but one day it starts getting disconnected from my WiFi network again and again. I thought that there would be a problem in my WiFi router but other phones are showing the WiFi and internet is working fine on them. Now my phone sometimes don’t even show WiFi network, even when it is near the router. Suggest some solution for this.

I'm using a Windows phone. The problem is, I cannot hear anything when someone called me. I can call them but I cannot hear anything even the tones when dialing. I tried using another mobile phone and call my own number, but even that, I totally don't hear anything. What seems to be the issue here? Any ideas?

I'm having an issue somewhat similar on my Lumia 920. Unfortunately, I can't simply solve it by turning data "on." In fact, I already have data on, I click on "Get media content (1KB)" for group texts and "Get media content (32KB)" for pictures, and for some reason it goes into a state that says "Getting media content…" but never actually downloads. So, I can't refresh the message nor can I try to re-download. It is extremely annoying to have to ask people to re-send things many times over. 

I put a password on my BlackBerry device when I purchased it. And now, I want to turn the password off but I have tried all the possible ways to do it, but I am still unable to turn it off. I searched on the General Settings but I could not find any option to disable my password. The Enable option has a small red padlock icon beside it and it appears that it was locked or something. How can I unlock it? Or disable my password?

Recently, I bought a new HTC Desire 616 which runs an Octa-Core 1.4 GHz, Android Jellybean 4.2.2 and a 1GB RAM. I am excited to play some games on it so I quickly installed a racing game which is more than 200MB in size. However, when I start playing, my phone suddenly stops on responding and worst is, it restarted itself automatically. I want to know how I can play this game without getting any issues. My phone is new and I still have loads of space on it.

When playing games with my Sony Xperia phone, it usually hangs. This happens for several times now. I tried to restart or shutdown my device, but the problem is, the battery is packed. Can someone help me in resolving this issue? How can I restart or shutdown my device? Is there any method that I can manually restart or shutdown it?
