UMI Iron, microphone and camera problem.

rafkas

\n\nHello. I have UMI Iron for about 4 months so I could test is quite deep and I found two main issues that bother me.

1. Microphone.
    The basic function of telephone is calling. With Iron it's not so easy... During a call, many people say that they don't hear me clearly, hear me really quietly even though I was saying words loud or they hear noises. This issue appears during calls with variety of different smartphones (so the problem is with phone of mine). The coverage is always good - mostly 4G, sometimes 3G. Sound from voice recording seems to be fine -  loud and clear.

    I have read this topic MIC problem solved but it's quite old so I would like to ask if there's any new solutions and also I would like to know will I lose my warranty if I'll dismantle the device by myself?

2. Camera.
    Buying this phone I was expecting much, much, much... better quality of pictures and video. My previous phone which was budget device for about 150$ had 8mpix camera (I don't know what lenses) and was making way better pictures - sharp and with good colors. But getting back to Iron. The main issue of the camera is hardly taking focus, also when I zoom the photos they are blurred and with weird grain which I have never seen before in any other made-by-smartphone photos. When zoomed, photos look like they were painted, not shooted using camera.

    What is the reason? Is it normal for this phone or I got defective device? Is it just low quality camera or something went wrong?

Thank you in advance for honest answers.
