I have a Huawei phone with Android installed. The LCD display cracked recently, and as the cracks have spread over whole display over few days, it's now totally uncontrollable.

The phone has a 4 way sort-of-joystick thingy, so when it's unlocked I can still use it. However, once the display turns off completely I cannot unlock it to use it.

Is there some key combination or a trick to unlock the phone without using the display? The phone is not password or key locked, it just requires to slide from left to right.

I have USB debugging enabled, but I have no idea how to use it. The phone is not rooted.

Also, I'm wondering how I'm going to save my phonebook and other stuff.

The device name is Huawei U8500.

You can use a USB cable and buy a USB mouse so that you can use that [a mouse] instead of touch screen. Check out a USB adapter for Android that fits your budget [and make sure it's compatible with your device] and purchase it.

  • I have a simple female-female adapter. Won't using this short-circuit the device or something?

  • No, I don't see why it should. I do the same with my Galaxy S3. You shouldn't have a problem, unless the cable itself already has its problems, but if the wire works well you should be fine.

    I'll try it then. If the phone breaks... well, I don't know who you are, but I'll find you and I'll eat you.

  • Lol. I didn't know cannibalism was legal. But I don't see why it should be bad. Test it out for five to ten minutes. If you sense something, don't. And unless you have a weak device, it should work perfectly. Assuming all devices, ports and cables aren't ruined and are in great condition.

  • Do you really think I'd reward bad advice by something legal? However, so far, the mouse does not work. Maybe it doesn't have that two-way port at all. I'll try some more mouses, but well, it's Huawei - I don't expect much.

  • That's hardly a useful answer for me, don't you think?

    @TomášZato That's not an easy thing to get around it easily, don't you think?

    Oh, well actually I expected the Android developers to think when they are making the systems. To think means to ask questions (and find the answers). One of the first questions should be: "What can our user do when the screen is broken?" I don't implicitly expect people to be dumb, therefore I thought they asked themselves the question. Because they obviously didn't, I guess my expectation about them was wrong.

You can use an USB OTG (on the go) adapter and a USB hub, plug the OTG in your phone put the hub in the adapter and plug in an USB keyboard and USB mouse

You can use a mouse using a USB Female Cable. I can use this cable to control my Huawei Assend. Then you can remove the lock to avoid interruption.

Try MyPhoneExplorer. Works like a charm for me. I have Android Gingerbread 2.3.5.
