As dubazar mentioned, you can buy a new glass/lcd/digitizer package but they are $135.

Another issue is that it only comes in black.

I recently replaced the screen on my girlfriends Voto X2 (Same as Umi X2) with very bad results.

The screen that you purchase is one whole assembly that is 90% of the entire phone. All that you use from your original phone is the outer case, the two small circuit boards and what I assume is the antenna. What I believe to be the antenna is the black tape surface that runs underneath the battery and has the sticker with the model information on it. This attaches to one of the circuit boards and has to be carefully peeled off and put back onto the metal frame of the new screen.

I have a lot of experience working with and building electronics and the task is not too difficult but after completing the screen swap I found that the power button no longer worked. The power and volume buttons are on one ribbon cable with integrated compression buttons. This cable is soldered to the main circuit board then immediately does a 90 degree bend to lay the buttons onto the side of the phone where they mount. The end of the cable with the buttons is glued to a small metal plate which is then glued to the side of the screens metal frame. You have to peel the metal plate away from the screens frame in order to swap the main circuit board over to the new frame. My assumption is that while doing this one of the traces in the printed circuuit cable broke. I was able to trace the circuit and found that one line was not making contact back at the soldered connections even though under high magnification I could not see a break in the cable. The break is likely in the connection between the layers of the printed circuit cable right at the power button switch.

I carefully peeled open the layers of the printed circuit cable and soldered a very very thin piece of magnet wire to the outside edge of the metal pad for the switch and soldered the other end to the proper pin on the circuit board and got the power button working again. I congratulated myself on my accomplishment and put the phone back together only to find that the proximity sensor no longer works. If you try to make or accept a call the OS turns the LCD display off and you cannot turn it back on. The screen will remain off until the call is ended at which time it comes back on automatically but you no longer have the ability to hang up the call or use the screen while the call is connected.

Looking at the new screen you cannot see the light and proximity sensors behind the glass as it is painted dark and this is the screen for the black phone rather than the white. In the hopes that the proximity sensor could not read through the darker coating on the inside of the glass I carefully scraped it clean from the inside but the sensor still does not work.

The sensors are soldered directly to the main circuit board and there are no loose connections to check so I am at a loss for what else to do unless I can find out how to disable the software call that turns the screen off or some way of making the power button responsive when it is in a call mode.

The other issue due to this being a dark screen is that the LEDs that illuminate the home, menu and return pads on the bottom of the screen are not bright enough to make those pads visible in normal light. It works in the dark but in the light you cannot see the icons indication the pad functions so you have to remember what is where.

The screen swap can be done but as careful as I was the phone was still damaged. At $135. for a replacement screen, it only being available in black and the ease in which the phone can be damaged I would recommend caution before making the purchase.

I have pictures of the inside parts of the phone if anyone needs them.

Speaking of the audo settings, what settings would max the volume on the phone?

I set the values to max on all of the modes but it has made no difference in the volume.

What are each "Type" settings for?. Sip, Mic, Sph, Sph2, Sid and Media as well as others under different modes.
