[Pixel C General] dkryder:
i'm wondering if it would be possible to identify problematic batches

of the pixel c to the serial. it has been done before with the nexus

9 that also had a lot of problems at launch.

5A2300 is first 6 digits of my device and i do not not have any issues

although my internet is cap @ 50down/5up. i am curious if there are any

batch differences at this point, or even if there are different batches.

Please report first 5/6 digits of serial, 32GB/64GB, and a concise description

of any issues. thanks.

Edit: i will try to tabulate the results in this post, updating every few days.

-serial----------model-------# report------------- issues reported -------------------- thru post 142

5A190---------[n/a]---------[2]-------[1]had chipped bezel and bad wifi,

--------------[32GB]------------------[2]Distance 12 ft

--------------------------------------Pixel C - 58/64

--------------------------------------iPhone 6s - 58/54

--------------------------------------Nexus 5 - 55/66

--------------------------------------Distance 30 ft + wall

--------------------------------------Pixel C - 58/64

--------------------------------------iPhone 6s - 58/64

--------------------------------------Nexus 5 - 55/66

--------------------------------------Distance 45 ft + 2 walls

--------------------------------------Pixel C - 58/65-68 (3 tests)

--------------------------------------iPhone 6s - 58/15-38 (3 tests)

--------------------------------------Nexus 5 - 55/40-54 (3 tests)

--------------------------------------Welp, seems like my iPhone wifi chip can't push out enough signal

--------------------------------------at the longest distance. My connection is supposed to be 50/50,

-------------------------------------but 55/65 is my typical speed on my PC connected to wifi dongle

------------------------------------at 20 ft. Nexus 5 has a TPU case. iPhone has a plastic polymer + TPU

-------------------------------------case. Pixel C has a standard Smartshell type case for tablets. Router

--------------------------------------is relatively high end (Netgear X4 AC2350) so if this tablet has wifi

-------------------------------------issues, it is being masked by the massive coverage of the router

5A2000-------[32GB]--------------[1]n/a

--------------------------------------[2]No WiFi issues. Massive slowdowns when battery dips below

--------------------------------------20%.

--------------------------------------Only fix I found is to reboot. At first reboot touch screen will

------------------------------------- unresponsive, but a second reboot fixes it.

--------------------------------------I ran an iperf3 test earlier this week. Results are here

-------------------------------------- http://xdaforums.com/showpost.php?p=66276497&postcount=35

--------------------------------------[3] display issue. has a band/shadow that runs the length of the screen. It is especially

---------------------------------------visible when the brightness is low.

--------------------------------------[4] Had the random reboots starting after the May security update. As of today, the

-----------------------------------------screen started acting up where half the screen would be digital "snow" and not

---------------------------------------- refresh even after a full factory reset. Currently in RMA process and new one

---------------------------------------- ordered set to arrive this week.

5A210----------------------------------No issues so far. Wifi about the same as my Nexus 7 and a little

--------------------------------------weaker than my S7.

5A2200-------[64GB]---------[2]-------[1]occasional system lag that clears after a reboot and had a

-------------------------------------------slow

------------------------------------------ WiFi connection until I assigned my Pixel C a static IP address.

------------------------------------------[2]no issues

5A2300-------[64GB]---------[4]-------[1]had occasional touchscreen and keyboard issues

--------------------------------------[2]Slow Wifi on 2.4ghz band. (4x to 10x slower download speeds

--------------------------------------compared to Nexus 6p testing at the same time on the same

--------------------------------------network)

-------------------------------------[3]critical data corruption after a month - device requested

------------------------------------password on boot, confirmed that thepassword correct but it was

------------------------------------unable to decrypt and required factory reset. Following factory

-----------------------------------reset, evice was stuck in a bootloop and could not boot into

-----------------------------------Android Recovery. RMA'd.

-----------------------------------[4]no issues for me either. So far I'm loving it, can't wait to try out N

-----------------------------------[5]5A2300 - fine for first the three months but now the dreaded half

----------------------------------screen freeze fault had started. Definitely a screen hardware issue as

----------------------------------it happens during boot too. Going to RMA

5A2600------------------------------[1]-No issues so far

---------------------------------------[2]- perfect no crashes on MM.

5A2700-------[64GB]---------[1]-------RMA- wifi is not so bad and no problem until now with screen.

------------------------------------------Just one point: it is more yellow than the first one, that was

-------------------------------------------more blue.

5A2800-------[64GB]---------[2]-------[1]Compared to my nexus 6p, wifi range/speed is not as good,

--------------------------------------------not a real problem for me as I can go around my whole

-------------------------------------------apartment without it the dropping connection.

-------------------------------------------I have had it for 24 hours, and have not seen any keyboard

-------------------------------------------problems.

------------------------------------------Will update if I see any problems.

------------------------------------------[2] no wifi or screentouch issues. Perfect quality.

5A290--------[64GB]---------[2]-------[1]No issues at all. At initial start Touch not responsive as

-------------------------------------------expected....but after update gone and no issues with wifi or lag.

------------------------------------- -----[2]Touchscreen issues after reboot/crash (fixed by booting to

-------------------------------------------safemode and leaving the table on/standby all the time) slow

------------------------------------------ wifi depending on the distance from the router

------------------------------------------auto-brightness appears to cause random crashes

5A300--------[32GB]---------[2]-------Both had wifi download issues and this second one has now

------------------------------------------developed a nice case of the touchscreen jitters. (fixed by

------------------------------------------booting into and back out of safe mode)

5B020--------[xxxx]---------[2]-------Wifi dropping [fix].http://xdaforums.com/pixel-c/help/slow-wifi-speeds-t3269506/post64398251#post64398251

--------------------------------------physically perfect but same bad wifi

5B0300-------[32GB]---------[1]-------ordered from Canada (shipped from Mississauga, ON) RMA'd

-------------------------------------------last Friday because had to reboot tablet (froze) and upon

------------------------------------------ reboot, persistent screen issues as reported by

-------------------------------------------many (swipes registered as tap, impossible to use multi fingers

------------------------------------------as 2nd finger is registered on and off, screen bounces back in

------------------------------------------opposite direction of swipe,etc.). No issues connecting to WiFi,

------------------------------------------5Ghz speeds are decent, 2.4Ghz speeds are ridiculous

-----------------------------------------1-2 Mbps downloads in the same room as router, few feet away).

-----------------------------------------Range of WiFi also seems to be much less than any other I tried

-----------------------------------------(Macbook Pro, iPad 3, One m8, Xperia Z3) receiving

---------------------------------------- RMA unit tomorrow (Dec 22nd) will update post.

5B0400-------[32GB]---------[4]-------[1]good WiFi and good screen, no problems.

-------------------------------------------[2]no issues so far, will report.

-------------------------------------------[3]Last update on my 5B0400:

------------------------------------------DEAD, hard drive corrupted after 6 days of use.(see post on

------------------------------------------troubleshoot subforum) Returned it to Google Store within

------------------------------------------Buyer Remorse Period..

-----------------------------------------The pixel c is so far the most unreliable device i've had. I never

-----------------------------------------had these problems with my previous nexus 10.

-----------------------------------------[4] poor bluetooth range. clear line of sight is 10 feet.

-----------------------------------------[5] Wifi bug ==> rma !

5B0500-------[32GB]------------------[1]aside from the fact that the Pixel C seems to have the worst

-------------------------------------------WiFi antenna in the known universe, this one has been flawless

------------------------------------------so far. Not one single unexpected reboot

------------------------------------------[2] display issue. complete right side of display is defective.

5B1200-------[64GB]---------[3]-------[1]good WiFi, good screen, no KB to test

-------------------------------------------[2]Mine has the dropping wifi issue. It also has some problems

------------------------------------------to recognize touches and gestures. The gravity of this issue

------------------------------------------varies alot. The third day using the Pixel C was the worst. Later

------------------------------------------it became better, but it still isn't perfect. Aditionally sometimes

------------------------------------------I'm not able to wake the tablet after it was idle

-----------------------------------------for some time. In this case I have to force reboot it.

-----------------------------------------Happend about four times now (using the Pixel C for two

----------------------------------------- weeks). Gonna return it after the holidays.

----------------------------------------[3]did not even want to turn on past the bootanimation. RMA is

---------------------------------------under way

5B1400-------[xxxx]---------[1]-------Keyboard is a big lagging yes, but for example, more on Firefox

-----------------------------------------than on Gmail.

-----------------------------------------My router is a Sagem Livebox Play (french people will see...)

-----------------------------------------I have, at best, 17/18m for the internet.

-----------------------------------------I did few tests, with Wifi Analyzer, Speedtest and speedof.me :

-----------------------------------------on 2,4Ghz, Pixel C is bad in my bedroom, 8m from router. It has

--------------------------------------- -70db signal, same as my old

-----------------------------------------Nexus 4. The N4 keeps a 12/13m speed, the Pixel barely hits 2m.

----------------------------------------Oh, and it doesn't finish the speedof.me test. Next to the router

---------------------------------------reaches 15m speed (speedtest) but... goes down

--------------------------------------after 5s around 3m. The speedof.me test

--------------------------------------gives me between 2 and 3m.

--------------------------------------on 5Ghz... Pixel C reaches 17m speed on speedtest, on speedof.me,

--------------------------------------ANYWHERE in the flat, even with -70db

5B1600---------[32GB]-------[1]------My replacement Píxel 32GB has the serial number 5B1600.arrived

-----------------------------------------today, no issues yet.

-----------------------------------------Does not have the screen clicking noise my previous píxel had.

-----------------------------------------It seems i have the first 5B1600 here, I hope it does not have

----------------------------------------issues

5B1700-------[32GB]---------[3]------[1]They both have same problem couldn't connect to 5ghz

-----------------------------------------network unless i change router to channel 44, which I've never

-----------------------------------------had to do with any of my 5 nexus devices. The range on it is also

----------------------------------------shocking. I did a comparison to my nexus 6 and nexus 10 and the

----------------------------------------pixel couldn't get the 5ghz in my room but the other two

----------------------------------------devices could and on 2.4. the pixel would only get half

----------------------------------------strength where the other two would be full. My room is not 4

---------------------------------------meters from-the router. Asus rt-68u.

---------------------------------------[2]random reboots. Many many reboots on M, and a few on N2

---------------------------------------Wiped the device and set up as a fresh device, but still get

---------------------------------------random reboots.

---------------------------------------[3] display issue, color banding on all backgrounds.

5B190----------[64GB]---------------LEDs on the cover are different brightness and occasionally get

----------------------------------------terrible screeching feedback when making calls via VOIP.

5B2000-------[64GB]---------[1]-------wifi is not bad but touchscreen problems come after +/- 2 days

----------------------------------------of normal use. After a reboot in safe mode, problems disappear

---------------------------------------for 2 days..

5B2300-------[64GB]---------[2]-------both touchscreen and wifi issues present Slow Wifi on 2.4ghz

-------------------------------------------band. (4x to 10x slower download speeds compared to Nexus

--------------------------------------------6p testing at the same time on the same network)

5B2400-------[32GB]---------[1]-------1) Slow Wifi Problem: Through Walls (193ms, 2.59mbps down,

-------------------------------------------7.88mbps up) compared to a Nexus 6

-------------------------------------------(3ms, 29.5mbps down, 51.79mbps up)-Of course, the Pixel C

-------------------------------------------software related performance issues are here. Regarding

------------------------------------------touchscreen responsiveness, I haven't felt any missed touches

-----------------------------------------however the touch gestures don't seem to be optimized for

----------------------------------------the Pixel C at all.

5B2500-------[32GB]---------[1]-------OK with 2 walls between tablet and wifi access point i have

------------------------------------------problems

-------------------------------------------Speedtest:

-----------------------------------------------------Ping-------------Download--------------Upload

--------------------------------------Htc one m8-------5-------------------41,7-------------------11,1

--------------------------------------Nexus 10 --------5-------------------50,1-------------------11,1

--------------------------------------Pixel C----------6-------------------20,8-------------------10,8

--------------------------------------Edit: The Pixel C also needs a lot more time to connect with wifi

5B300--------[32GB]---------[2]-------[1]have touch screen issues like swipes responding as touches

------------------------------------------and when they do swipe it's chittery, but Wi-fi speed is fine.Wi

-----------------------------------------Fi Speed test: http://i.imgur.com/ODqXJoH.png I'm 2

-----------------------------------------floors away from my router btw on 5Ghzs Touch screen is my

-----------------------------------------main issues

-----------------------------------------[2]no random reboots on MM.Many Many reboots on N2

610700--------------------------------no problems. Android 6.0.1 - March Patch.

612300--------------------------------No touchscreen issue (after I updated from stock). WiFi was

---------------------------------------never an issue, even in the upstairs room on the other side of the

---------------------------------------house away from the router where my nexus 10 struggled. As for

--------------------------------------the corrupt hd issues, I have a feeling it has something to do

--------------------------------------with magnets, but I don't have the keyboard and I don't

---------------------------------------plan on testing that theory. Fwiw I'm running the n preview and

---------------------------------------everything has been great aside from the expected bugs on the os

---------------------------------------side of things.

61250--------------------------------yellow tint bottom of screen.

612600 -------(64GB) -------------Perfect device, Wifi is OK, screen is OK.

6127----------------------------------Received mine 2 hours ago. It's a 64GB I still need tot try it out

--------------------------------------and test.Speedtest was promising

--------------------------------------with 25Mbps higher then my Nexus 10

--------------------------------------I have very mixed results going from 173Mbps to 6Mbps.

--------------------------------------1st try 10m with 2 doors in between @ 37Mbps.

--------------------------------------2nd try @ 84Mbps.

--------------------------------------1st try upstairs around 10m @ 34Mbps

--------------------------------------2nd try @ 69Mbps

--------------------------------------Upload speed is capped with my ISP at 12Mbps so I always get this

--------------------------------------speed

61300 --------------------------------Perfect. No gaps or creaking and wifi is fine. Success at last.

620100--------------------------------gap between glass and metal case under the power button,

----------------------------------------except this one is longer along that top edge before it meets like

----------------------------------------it does around the rest of the tablet. Google escalated...

--------------------------------------Will see what happens. Otherwise, fine with wifi and no screen

---------------------------------------issues or clicking!

6202000xx------[32GB]--------[3]------[1]Perfect. No WiFi issues, no touchscreen issues. I have

--------------------------------------------noticed chrome fails to scroll a pasge sometimes, -but that's a

--------------------------------------------browser bug, not a touchscreen bug.

--------------------------------------------[2] No issues

--------------------------------------------[3] 64GB. wifi issue. also clicking sounds from pressing on display.

-------------------------------------------[4] - random reboots, RMA

62030---------------------------------I've just got a 32gb in UK with dev discount C1502W 62030 no

----------------------------------------issues so far with 2 days of use as tablet only no keyboard. It's a

----------------------------------------monster eats media and web pages all day long like nothing

----------------------------------------happened!

Miscellaneous Comments----------------Router in the basement, so through one floor and its in a

-----------------------------------------------separate closed room. Pixel C 22 ms, 5.1 MBS dwn, .73 mbs

-----------------------------------------------up. Nexus 6p, 19 ms, 5.9 MBS down, .68 mbs up.

-----------------------------------------------Yes my DSL sucks as I'm in the country. But my Pixel that

-----------------------------------------------arrive today does not seem to have the WiFi issue.
