My screen on my Motorola Droid Razr slowly started cracking last week, and it neither displays anything nor allows touch events. I can connect it to HDMI, but I can't do anything beyond that. I have recovered all files available via the USB connection, however most of the stuff I need apparently requires root access or a backup program. I bought: A mini USB OTG adapter A mini USB to Micro USB adapter after figuring out that the specs for the phone that I read were wrong. A powered USB hub A USB mouse However, although the mouse receives power and appears to be physically connected to the phone, the phone does not seem to recognize the mouse. I cannot find any way to feed input into my phone. I do have a replacement phone because I had insurance on it, but I really, REALLY would like to get the full data backed up before I have to return the old phone in the next couple days. The android version is 4.x, but I don't know the exact number. I've been googling for the past few days, and now that I finally got my hands on an OTG adapter, it doesn't seem to work. The few solutions I've seen require an earlier version of android, access to the screen, and some electrical engineering to make OTG work.. that doesn't seem quite right. Is there some other way to deliver input to the screen? The device is NOT rooted.
