Can my mobile be used as Wi-Fi hotspot? I always heard that latest smartphones can be used to share internet connection. What kind of mobile connection is required? Can anyone who tried it, tell me how it is in terms of connection quality? How many devices can be hooked up without losing speed?

I just bought an HTC one m8 and I was wondering what protective case should I get? Through quick browsing, I found a number of cases, but the one which interested me the most is the dot matrix case by HTC itself. Can anyone provide me with a good comparison for available cases? Also how does the dot matrix work to be able to show live notifications when the cover is shut?

Recently I have thought of taking photography as a career. I was wondering what the best mobile shooter is as at late 2014 and beginning 2015. I am mostly on the move and having a mobile phone with a quality shooter will greatly help me in terms of spontaneous shots. 

Why is my blackberry Z3 smartphone selecting a charger before it charging? My blackberry phone started selecting charger. Sometimes it will display charging, but after some time it will display charger not supported. Although, after some time if the charger is removed it may start charging. Is it a virus that is causing this behavior or it is something more serious?

I am planning to buy the LG G3 . I have read a lot about the laser autofocus in the phone and I have a question regarding the battery life and video recording. Does the laser affect the battery life significantly ? Because I use the camera a lot, I would like to have a phone with a decent battery life. Also, can it help in recording video? Changing focus and such? What other purposes can it fulfil? 

I recently bought a new Samsung Galaxy S5. From its start it had an charging issue . sometimes it doesn't gets charged up properly, it may be refusing to charge at all or it might charge extremely slowly. So i would like to know that is there a issue with my hand set or there is some other issue ?

My Samsung galaxy S4, 6 months old is running slow and getting stuck. Sometimes the mobile is switched off by itself and my many important calls are missed. Due to this my life has been messed up and I have to keep checking if my mobile is switched off or on.

I am not receiving calls from one of my Friends. Though I can view missed calls from him in my screen but I am not hearing any call. It seems he is in my Block list. Please let me know how to view rejected list?

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. 

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.
