Strength of network signal unstable - Zuk Z1 Q&A, Help & Troubleshooting

Hi all,
I recently bought this phone, and I'm very satisfied.
However I found a "problem".
The strength of my network signal is very unstable.
Without moving the smarthpone too much, It varies a lot.
Here there is an example, i didn't move the phone and I didn't change the way I handle it (or at least not too much): Unfurtnately I can't post outside links...
I started monitoring the signal, and it was very high. Then it started to go down.
When it was near the zero, where is the green arrow, I made a phone call: the signal went up again.
So, seems, that while the antenna is in idle the signal is very unstable. But when I make a phone call, the signal strenght goes up.
What scares me is that the signal strength varies too much while not on call. Just see the spike before the arrow...
Someone has experienced this too?
Is this normal?
Thank you very much

In the US I was using a Note 2 for a couple of years on the Verizon CDMA network. I must say the Note 2 on that network has been pretty reliable and I live in a rural mountainous area. I got my Zuk and I could not use Verizon plan with it, so I got a pay as you go plan with At&T GSM to demo it, because I really wanted a dual sim phone. The service is not as good, I work at many locations where I have to go in basements, and even in the city areas where I have full 4 bar service, I cant keep signal with the Zuk, but with the Note 2 it is no problem. In my home basement I can keep service somewhat, but sometimes I even will miss calls. I wish I had a spare AT&T phone that is sold in the states to compare it with for service.
So sadly I think my trial with my beloved Zuk is coming to an end and it is going to end up on Swappa before long.

I got your point: maybe the ZUk Z1 doesn't have the best reception ever.
However, apart this, I'm experiencing a very strange behavior.
Almost motionless, the strength of the signal varies too much.
But, maybe even more strange are these snapshot: the green arrows indicates when i started a phone call. (here too, the phone almost motionless)

Possible that i'm the only one experiencing this problem?
Of course, where the signal is stronger I don't have these problems.
So, I think there is a bug in the managing of the antenna
Sorry for the broken links, otherwise I didn't can post them.

Let me look and see? I can see the bars in the notification area are not for real.
How did you bring up the advance strength meter, I would like to give that a try?

It's an application that I downloaded from the store.
In italian It is called "Info Segnale Rete"

Me too Bro.. Recently bought this phone and now I am having very poor network reception for Airtel telecom operator in India. Places where i used to have good network coverage with my previous phone aren't any longer a good reception area when using Zuk Z1.. When checked in GSMArena, i saw that zuk doesn't have that much bands supported for 4g/LTE. However, that shouldn't mess up with the 3G/2G signal receptions, right.? Any idea that updating to /CM 13 will help.?? Or any other option to upgrade the radio firmware so that network reception will be better.? Pls lemme know if anyone has some clue on this.. Thanks in advance..

Problems losing signal while driving with 8125

So I have been able to repeat this problem. I noticed it just started happening in the last 2 months or so.
Scenerio:
I turn my phone off (or screen off), start driving say 3+ miles. When I get out of my car, I turn my phone back on. Then I notice the EDGE icon has a X and the signal bar has a X. It then proceeds for about 5-10 seconds finding a signal pretty quickly.
Now I know for a fact that during this time when the phone is off, I am unable to get calls because it doesn't look for a signal until I turn the phone on. This is a pretty big problem as this obviously shouldn't be normal. Anyone else experience this?
I currently have the standard 64K sim, didn't get the 3G yet.
anyone experience this?
i guess it depends on where u live, and where towers are located.
I haven't noticed this behavior.
What's the deal with the 3G SIM? Can we swing by any Cingular store and pick one up? What's the benefit over the 64k chip?
It sounds as though the 3G card doesn't benefit the Wizard at all, too bad this brand new device doesn't support the newer technology
3g isnt even available anywhere yet. i think its only good on 4 city blocks of NY or somewhere completely remote. 2008 i think
im in nashville, 3g works nearly all over nashville on my blackjack. It would be awesome if it worked on my 8125 aswell, sadly, only edge is working!

Dropped calls from my X1

Hello guys,
I just got my X1 (Generic_UK) few days ago, and i was shocked by the poor reception or i might say the dropped calls by the phone.
In fact each conversation the phone was managed to dropp the call by itself after 2 -3 minutes maximum, so i had to call the other party all over again.
I updated the firmware to R2AA010 yesterday and switch the network to GSM only, and that didn't fix this problem, and i also used my friend's card (different carrier and end up with same result)
Any one can help me with this issue ? if I'd never fix this problem , I'd definetly sell it out.
Thanks.
probably won't help, but my phone shows exactly the same behaviour.
i am on a 1800 GSM network.
an update of the radio rom to the newest version that is available here on the forum did not help.
TBH this sounds like a phone fault... mine works flawlessly and now that I have 010 ROM its even better... are you in a very remote area? if not perhaps its a fault and you might need to take it back?
The HTC Touch HD seems to be affected by exactly the same problem. (link)
Strange
Well, I'm running the Voda X1i but flashed to Generic UK R2A_10. I have had nothing but perfect calls, only 1 call dropped but I don't think it was my fault because my signal was max.
It's true the signal is often low, I keep it next to my iPhone which is also on voda and comparatively the iPhone has better signal, but the sound quality in my iphone is appauling and in comparison, when I make a call on my Xperia it's like the person is standing next to me.
I have put up with the BS from my iPhone for too long, as well as the horrendous echo that anyone that calls me suffers from and invariably complains about and refuses to call me.
If you're in a good signal area and you're still getting problems on R2A_10 i'd recommend returning it for a replacement.
X1 definitely has serious reception problem.
I am not taking about the number of bars but off and on signal are comepltely gone and it will start searching for a network.
I have tested this by putting the phone on the table and by observing the signals bars over a long period of time. Often I have noticed full signal bars and many time there are not signals at all.
Service is weak in my area but none of my pervious mobiles have shown such a poor reception.

same here, ive had major reception issues compared to other handsets on same network
I have never had any problems with reception or dropped calls.

Dropping Signal

Hey there people.
Hoping I've not missed an existing thread.
I'm having problems with X10 dropping its signal seemingly through its own free will. Had phone since mid april and not had any problems with. But the other week me and the missus noticed occasionally i wasn't receiving texts she had sent me. This happened every now and again for a few days. I then noticed when i picked up phone it'd show signal on 3G as maybe 2 or 3 bars then suddenly drop too nothing, showing the little x indicating no signal. After a few seconds up to a min it'd pick signal back up and work again. I no for a fact its not me been in an area without 3G coverage because it happens at work and until this started happening i got a strong 3G signal there. It doesn't seem too switch too edge either any more. Its set too GSM/WCDMA prefered. I'm on 02.
Anyone else have similar problems or any clues on what the problem it.
Cheers

Data dissappears during phone calls? Realization time

Has it always been like this? Flashed a few roms and radios. But I think I never really thought about it or noticed it until now and it's really bugging me. I've read a few topics about 3g and 4g being "parallel" to our voice calls so we can't have both? I don't quite understand any of it.
Can someone tell me it's just my phone so I can try to solve the problem, or reassure me that we can't have both at the same time so I can sleep better tonight? lol
Thanks for any and all help!
Edit: Sorry meant to post this in the question thread.

ALL GSM phones that are connected to HSPA or greater should be able to talk and surf at the same time. I do it frequently personally. Do you know if you drop to EDGE/GRPS when you get on a phone call?
I am also having this issue but its strange that the guy posting above me does not face this issue - may be it is a hardware issue like screen and emmc since I already tried different roms and radios?. As soon as I am in a call I am disconnected from network data. I noticed only recently when I was in a hotel room working on my laptop (tethered phone to provide internet) and just when I joined a conference call, I lost internet. It was so embarrassing I couldnt curse tmobile and htc enough. The iphone ad about talking and surfing at the same time never made sense to me before this incidence.
my phone does this too, but its on and off. Sometimes it does, others it doesnt. I really have no idea what could cause it.
Let me shed some light on this....if you are on H will less then 2 bars and theres an E with 3 bars or more and u get a call the phone will switch to E but once you hang up then its back on H. But if H has 3 bars or more when a call is received then I will stay on the H network and allow talk and data at the same time. Theres no hard ware issues trust me. Hspa is preferred but if there is a stronger signal then the phone switches. I hope that makes sense. You can not do data and talk together on E but you can on H.

Or, to put it in other words: when the phone is in a call, it'll hop to the "best sounding" base station, and if it would happen to be the old GSM/GPRS/EDGE base station - the data will drop. The missing bit is: once it drops - it isn't re-negotiated during the call, only after it. Thus, if the phone hops to EDGE base station even for a second during the call - you won't have data from this point and till the end of the call.
Perfectly normal behavior.

This is definitely not the case. I have tried multiple times with different signal strengths but it drops completely every time. I just did another test, I was on H at 3.47mbps with all full bars and as soon as i placed a call to my friend, the data dropped completely.

It's not about the bars you see, but the signal strength (and not only) your phone sees - which is way more complicated than just bars. Read my post above.
And it's not an opinion either, it's a fact. This is how cellular handoff/handover works. http://en.wikipedia.org/wiki/Vertical_handover
Thanks for the replies and insight everyone. Now I know a little bit more about how that handover works heh.
In my case, most calls were made from my office building. Yesterday, when I posted, I had the newest radio and data would drop immediately as soon as the person answers my call (not a steady drop from 4g-3g-Edge, icon just disappears completely). At best, I was able to download a few apps during a call (which was downloading before the call was made) but as soon my screen locked and turned off - the data was gone on wake and wouldn't turn back on until after the call was finished.
Went through 4 different ROMS yesterday with about the same results but I have recently reflashed RoyalGinger again along with the stock radio thereafter and it seems to be holding during calls, even on my ride to work this morning. I know this is against what most people have said in this thread but maybe I just messed something up on my phone with the new radio? Guess I'll stick to this radio for now. Thanks again everybody.
Radio is the one responsible for determining the best possible connection, and flashing new radio might change things.
I'm in a good 3G/H coverage zone, with new radio, and just tested - the data remained on during the call in any conditions, screen off, screen on, wifi toggling - still worked.

When I'm on 4g and turn the screen off the data turns off, normally after an extended period, which its good for battery.

This has happened to me since I had my blackberry 9700. My experience has been that it loses all data (H/3G/E), even in good H/3G signal area and won't reconnect until I end the call. However the data loss only occurs while on a call. While not on a call, just surfing the net or using data any other way does not cause lost data connection nor a drop from H/3G to Edge. I saw somewhere on these forums that switching to H/3G only will prevent this from happening. I've tried this and it seemed to help, but I haven't been checking on every call.

[Q] phone working in very weak signal strength areas

Just asking. What would happen to a phone working under very weak (most of the time, one bar to none) mobile signal strength. Where I stay has exceptionally weak signal strength. I noticed that one of my i9505 shuts itself down intermittently at home. Doesnt happen elseswhere. My other i9505 has a dying wifi. I have just moved to this new home. Never had such problems before this.
What are your thoughts?
You'd probably see higher than 'normal' (that's relative tho, obviously) battery drain. I certainly notice this when I use my phone at home (weak signal mostly) Vs when I'm out & about (much better signal). Never known of this sort of thing to cause shutdowns though, unless there's some kind of firmware or hardware issue which gets triggered by weak mobile signal (again, never heard of such a thing) ?
