Just purchased the Droid 4. Have had only 4 days. First thing out of box while on phone with Verizon Wireless to activate my account the back light on physical keyboard would go on /off in front of my eyes without me changing the lighting at all. Sitting on my knee with hands to side (not even toching the phone) went onoff wildly. Took 2 Tech people to direct me to the settings/dimmer/un-check auot dimmer. I DID THAT. Worked beautifully for 2 whole days. Even got 2 whole days (48hrs of a charge on it) so from what I was reading, I was happy. I loved the phone. THEN, went to bed the 3rd night, down to 20% battery so charged it over night (turned it off to charge). Got up next morning, 100% battery. About an hour into the morning rec'd a text, went to reply and noticed my keyboard was not lighting up? I remembered a thread from this forum (somewhere on the web) and it was recommended to go back into settings, quickly check and uncheck the auto dimmer again (kind of like to 'trick' it back)? Why we do this doesnt make much sense as it is not a button but a virutal setting. didnt work. Tried rebooting - 3 separate times, still didnt work. Tried uncheckint the auto dimmer, backing out to menu again, going back in and putting back to highest bright seeting with the auto box UNCHECKED..still no light. Pushed the keyboarde in /out over and over - that didnt work. Went in to every other setting I could find relative to keyboard..language and settings, dimmer, time out, power. Called tech service NUMEROUS times. Physically went to a Verizon Wireless Store - guy transferred all my contacts over from LG Envy, replaced cover and put a screen saver on..again, nothing worked. He held his finger over the sensor, the keyboard would light up but I didnt have the auto sensor checked at time so in my opinion it shouldnt matter. Verizon wireless clerk tried to tell me the backlight was only for when its dark. I explained to him then why is there a auto dimmer switch even there and it gives you the OPTION to select settings. I had mine turned off and on brightest setting. I informed him it worked round the clock for 48 hours until I booted it the night before. Couldnt answer. Called MOTOROLLA. That was even more painful. Scripted customer service that spent more time trying to tell e what I wanted to hear then fixing the issue. Told me I needed to do a factory reset after only having it for a couple days, despite the fact it worked fine the couple days before when I first unchecked the dimmer, he wanted me to remove everything? I told him no. Its gotta be some issue. Now I believe that the sensor is acting "as if" I have the auto on. It is not registering the FACT I have the setting turned off and that i have brightness turned all the way up. Now I have invested 2 whole days trying to resolve this. I have read others experiencing this but they say just change setting in auto dimmer, THAT IS NOT WORKING ANYMORE. Now what do I do and why is this problem KNOWN in the DROID 2, still an issue in Droid 4? why release a bug when it was known several modesl ago? I have read about this same exact issue in later models??? Why can't I find any info on this outside of changing the dimmer, well, what if I have done that?? I find it hard to believe I have the one phone that has a bug, so to return it for another Droid 4 seems like banging my head against the wall even more. I have called Tech Service both VW and Motorolla and checked these boards within REASON as I dont have time to be doing even this. For me, I can digest the crappy camera that is totally fuzzy and horrid resolution..EXACTLY like my LG Evo????? I can take the crapware we have to deal with on these phones, but the one thing I really and ONLY wanted was the decent keyboard and now it is not working. I was standing in my garage in total darkness and had the auto feature checked and it STILL would not turn on. So the concept of it working only when the light is there is not an argument at all. The keyboard light is not working correctly. The settings are not registering and I still have no light even in a DARK GARAGE where I could not see the keyboard at all. Before I return this and NEVER purchase another Motorolla phone again, is there ANYONE out there that can help me fix this without having to go to another phone? I l ike the phone even without the decent camera but I will not be able to tolerate a phone that still has a known bug in it without a resolution that I can control at this junctior. If the backlight is someething I am asked to "live with" then I will live without this phone.
