Xperia Tablet Z death grip? - Xperia Tablet Z Q&A, Help & Troubleshooting

Hello!
I really love my new tablet, it looks so slick and cool!
But the wifi on this bad boy is really disappointing.
I can almost kill the entire signal by holding the tablet in one hand (the death grip).
This is reception with no hands

Down to one bar and DC's, and this is just my fingers blocking!
Also happens if I lean it against myself on the couch (as a normal tablet user)
I would like to point out that my router is standing in the crack between the wall and cabin in the far end of the picture, no walls betwen
It also happens when I hold the tablet out in the air in one hand.
Is my unit at fault or is this a general thing?

If the signal drops when you are holding it that way, it does seem that there is something wrong. What make of router do your have?
My signal drops to one bar if I go upstairs or out back, but I can still connect to internet, and the play store fine.
I have compared my xperia and nexus 7, and there is not really any major difference in wifi signal, I would say you have a faulty tablet, or a dodgy router

Yep, sounds like you might have a faulty unit. I don't get a drop in connectivity no matter what way I hold it. I often sit on the couch with it leaning against me and have no issues.

Hi.
I got my Tablet Z a few days ago and have noticed my Wifi connection becoming incredibly weak (even when I'm in the same room as the router) sometimes. Although, I haven't been able to reproduce the issue. I'm more concerned about the Wifi/Bluetooth bug that renders the tablet unusable when I'm using my Bluetooth headphones.

interesting WIFI Bug

I noticed today that my WIFI was exceptionally slow on my device. Being 4 feet away from my wireless router, i was getting 1-5 mbps speed..
my router has a function that lists connected wifi devices and the assumed connection speed.. it said my Transformer was connected at 58mbps.. so something was fishy
Everything was exceptionally slow, even browsing. after a simple full shutdown and startup it was back to normal. maybe this is the wifi bug some people were having? anyways, a restart made it exceptionally better
anyone else come across this?
Haven't seen this yet but it does sound like your unit has a wifi defect. :banghead: I can say the following two things:
1. The operating channel/frequency does seem to make small differences. Probably noise in my environment.
2. Wireless range seems to be short. I'm getting no where as good of range as my iPhone can. I'd say its short by a good 25 feet or so.

well the weird thing, im normally fine. i play was playing spotify (high BW audio) in my driveway (through two walls and total about 50 feet) and was getting great reception.
just had this one issue. weird.
It's not a bug. The 58Mbs is the reported link rate, not the actual throughput. Many people mistake the link rate for bandwidth.
I think some of the lag mentioned (elsewhere) are due to poor wifi connectivity.

Prime Review

Never posted here and perhaps this post isn't necessary but felt compelled. I preordered from Amazon on 11/22 and was salivating for a month until the GPS issues started to be reported. The salivating turned to apprehension. On 1/3 I received the Prime and it is indeed gorgeous. Sadly I'm suffering the same problems as most. No need to beat a dead horse. The GPS issue I can stomach since I have a bluetooth Garmin that works fine with the Prime. However the poor GPS performance is extremely disappointing. Simply transferring files from my laptop to the Prime over wi-fi was much slower that transferring between other devices in my home. In fact so far I'd say it's unusable in that regard. I should add that I'm sitting less than 3 feet from my router when transferring.
Perhaps my expectations were too high but with the keyboard my plan was that this device would replace my laptop for all but the most rigorous tasks. That's not going to happen and now I'm not even sure I'm going to order the keyboard.
BTW BT is weak as well. If all of these issues are indeed due to the aluminum case it's just unbelievable to me that a company could screw up this bad. I'm hopeful that someone comes up with something even if it's just providing instruction on how/where to take a drill to the darn thing. But my expectations aren probably too high on this front too.
In short unless someone has disposable income I'd advise they steer clear and wait for a better offering. I'll likely keep mine until something better appears then I'll be putting it on Ebay.
That's not review, you are beating the dead horse....

Well I guess you're right. A mod can remove and my feelings won't get hurt.
I guess I just wanted to get my shots in on that horse.
ride the dead horse.
a drill won't fix it. you need to point the screen at the router.
the entire foundation of the tablet is built into the aluminum case. everything is screwed into it.
the antennas are on either side of the front-facing camera. want better reception, point the tablet screen in the direction of your router or BT tether
How to Bluetooth tether?
>How to Bluetooth tether?
Put phone in one can and tablet in the other (use bigger can for tablet)

I have solved MY weak GPS problem

This may not be the solution for you but I got a GlobalSat BT 368 that is about the size of 2 match books longways and thick ways. I use the free bluetooth gps in the market and I now have GPS better than my epic 4g or my wifes 4g touch. In fact I am now thinking about getting a full size navigation program like copilot or sygic any thoughts on a good program

Looks good. How long battery last?
Can't tell you from experience I only got it thurs. Its rated at 11 hours continuous use but cuts off after 10 mins. if not connected. If it's anything like a speaker phone with the same ratings and features it will probably need charging every three weeks. 2 hour charge.
I have been thinking about just leaving it plugged up in my glove compartment and on continuously. Once locked it doesn't lose signals for anything that I have been able to try in the house.
HI,
Glad you got your GPS working. I don't know type of phones you have available, but if they are Win6-7 phones, there is a program out there called WiFiRouter (costs, but it works great....use it all the time), then you can use a free program called WAZE that uses online data. I find the routes selected, but the the nice thing is that it is "user-interactive"....that is, users identify construction/police/slow-stopped traffic. It should work great in DC. Other than that, I'd go with CoPilot for now because it's cheap. Magellan and Garmin have operation apps for the iphone, but not the Android Market yet, and those are the 2 companies that I would recommend.
Personally, my current setup is a Garmin 4390 standalone, with WAZE running to let me know where the traffic and cops are. Haven't had the Prime long enough to see if there's any others available....The other company to look at is Tom-Tom.
If you're going to connect the Prime to the internet via the phone, then you probably need to apply this fix, so ad-hoc networks are available. ICS stock has them locked out.
If you have an Android phone, there are apps similar to the WiFiRouter, I'm sure.
Good luck,
Bob

Wifi antenna

Hey guys, long time reader, first time poster here (and it's a long one too).
My OnePlus X is my daily driver and I was planning on using it for some more years if this is fixable
Recently the USB port started to fail, so I decided to replace the part. A little setback was that i also had to replace the GSM antenna cable, which I had damaged during disassembly. So far so good, the phone is now charging again and reception and mobile data are working fine.
However, ever since the repair my Wifi reception has gone to ****, it is now so bad that it's pretty much unusable even when right next to the router. I've come to the conclusion that this is not a problem with the antenna cable replacement, as removing this cable only kills cell reception, wifi is unchanged. You can see the cable i'm talking about running into the long side of the frame in the bottom of this

, with the golden connector on the lower edge of the motherboard (the other side connects to the USB flex cable, under the metal housing on the right). I believe the Wifi chipset itself is contained within the small housing in the upper middle of the board, with the + sign.
So now on to my question:
Does anyone know where exactly the wifi antenna on this phone is located? I'm assuming that it is being routed into the plastic/metal housing cover that's over the mainboard. I've made sure that none of the pins on the motherboard that connect to the housing cover are missing/bent or corroded. I've angled them up a little bit and cleaned them with alcohol to ensure a good contact.
But still, no wifi. Is it possible that the wifi chip itself got damaged in the repair and is there any way to find out?
Hopefully someone here knows something useful, I would be eternally grateful
Did you ever find a fix? I am having similar problems for one plus 3t
No, zero news on that front. I did some superficial research but was unable to pin-point the fault. I had to replace the phone, sadly.

A potentially unpopular opinion...

This phone can completely work as a laptop replacement.​
For everyone? No, there will always be things that don't work for some people, missing features, sacrifices etc.
But for me? Well... yeah. I had a bluetooth keyboard and trackpad from like, 3 tablets ago. Seriously, that keyboard is going on 4 years old now (the majority of that time spent gathering dust in a draw, if I'm honest). Upon stumbling upon it, however, I thought I'd give it a go. My Note 10+ has a kickstand case so now was the perfect time to test it out. I connected everything up, sat down at my coffee table, and poked around.
My first test was copying a whole bunch of stuff from a PDF into my Fifth Edition Fight Club app. That is to say, reading text from one screen and typing it into another. CTL+C and CTL+V worked when copying other text from discord or Word. The side by side windows were brilliant (the one annoyance was when I started typing, not realising I had the wrong window in focus).
Normally I have YouTube playing random videos in the background when I'm doing stuff like this, so I had some Doctor Who playing in my video player in a floating window for a little while as well. Ended up switching to Play Music after a little while, however, because I found I kept moving the window around. The addition of the pen for navigating the tiny screen was actually perfect though. The trackpad was... ordinary (but again, 4 year old keyboard, I'm honestly surprised it worked at all)
Sure, the screen is small, but I had an EEE PC 701SD back in the day. I live for tiny computing.
Final thoughts? I wouldn't use this in the house while my Razer laptop and its second monitor are two rooms away, but to catch up on stuff while I'm away from the house, it actually works AMAZINGLY well, even without on-device Dex.
Kudos, Samsung.
After a while, I prefer to use it when it is in portrait mode. Especially when switching between browser, WhatsApp and telegram. Portrait feels better
