Got my Sero 7 finally! Running stock oem ROM after reboot and so far everything I tested, Cameras, LED LIGHT, GPS, SPEAKERS, WIFI, SCREEN touch is all working like it should with no issues. I did have the tablet reboot on me for some reason when I was running andftp downloading a 500 meg file using 54g wifi and that was in background while I was using google movies to try and play videos and downloading in background with the play store, once it rebooted it was telling me the battery was 4% charged and almost dead then went to 1 percent and died but I continued downloading files from lan over wifi.... so I think it killed the battery. this was after already playing with it for 3 hours and it was 50% charged out of box....
One thing I did is disabled using wifi access for location access and only enabled THE HARDWARE GPS and google access to it.. For some Reason where I live on west coast in WASHINGTON, the GPS does take anywhere from 15 seconds to a minute to lock on to 8-12 satellites. It is not instant as some other users have reported and like I said i disabled wifi network location setting... and only GPS enabled..
My screen so far as touch goes, is working like it should no skipping, dead spots, or weird crazy issues thank goodness!!! Cameras take decent pics even the front one they are installed correctly and are the correct direction. Flash works not far distances. Built in Microphone works pretty good using Tape-a-Talk Voice Recorder. No background static and it picks up far away noises and up and close audio good!
All my apps I have on phones and other tablets installed without a hitch and work correctly, so far screen quality isnt perfect, there is some very minor light bleed around edges on dark and white screen and the screen isnt installed perfectly into frame, its more over to the right side and top side than the left and bottom in frame. for the most part when using lcd test or dead pixel test you get solid colors with even brightness...
Speakers for the most part are on par, they are super loud compared to other tablets, they have no bass what so over, only mid and high range comes out. I covered each speaker while leaving opposite uncovered and I think the audio/volume quality is different between the two speakers installed, there is a hair in difference between the two of quality or volume so they are not dead on or 100% perfectly synced...
I am charging it now while its completely off and then will test bluetooth with HID headphones and built in mic. I will try GrooveIP using bluetooth headset and without to see how that works and sounds calling people using VOIP... Also still have to test the SDCARD slot and the HDMI OUT and plug it into my VIZIO 42" 1080p 60hz lcd tv...
GOOD NEWS PREVIOUS NEXUS OWNERS.. so far NO DAM SCREEN FLICKERING AT ALL in ANY APP!!!! that was the number one thing that made me return 3 nexus 7's and give up on them! Google maps and gmail and the browser showed no screen flickering as of yet using the stock brightness setting from out of the box without the auto brightness box checked!
There is two weird settings I havent played with yet, one is the power management for I guess the whole tablet and there is a power management enabled by default in the wifi settings which i left enabled and wifi is working great so far on 2.4ghz. I have yet to try my 5ghz wifi...
I did get two sero 7's shipped to me from CALIFORNIA and only have played with this first one and so far everything is working as others have reported except the GPS taking a while locking satellites. I got two to pick the best one out of and return or sell the other one!
I have a sticker that I assume is the date my tablet was made and it says 4/20 on a small white sticker on back of tablet.
I got no outside external issues around the frame, edges, back side or screen... The cameras are not perfectly centered in the lenses on outer shell and are both a little offset. but they still work great, and take photo and video fine... will share some of that later...
Just wanted to update everyone...
Got an extra one!
