Signal strength very unstable - Zuk Z1 Q&A, Help & Troubleshooting

My ZUK's signal started being very patchy. It goes up and down most of the time. So far i tried a factory reset and a new sim card, but no improvement.
I'm attaching a screenshot below.
Anyone has any suggestions?

3G connected but no data on Xoom

Anyone else had issues in which the Verizon 3G is connected and shows good signal (2-3 bars), but the signal bars are grey (instead of blue) and data doesn't work? I have to reboot it to resolve this problem.
I am also having this problem with WiFi in which it shows great signal strength, but the bars are grey instead of blue and no data flows. This one normally resolves itself after about 1-3 minutes.
I've seen people report issues with a WiFi memory leak issue, but nothing about the 3G doing the same.
Guess I am the only one having this issue. But I am tired of it now and it's going back to Verizon.
I have attached images of what it looks like when it loses the data flow, and one right after rebooting showing it working after reboot.

Radio Issue Needs To Be addressed

On the latest radio 4.12 I noticed that the signal drops every minute for about 10-20 seconds. I have good reception in my area, normally 4-5 bars. The only work around I have is dialing *#*#4636#*#* changing to GSM only. BUT, when I reboot it goes back to default WCDMA only, I'm on bulletproof miui, latest pershoot, latest radio and yes, I've tried data EFS wipe and v6 and v3 of automatcher. Please help!!!
soooo.... go back to your previous radio that worked for you?
Been running this radio since it was posted. I have lost complete signal twice, only need a hot reboot to regain signal. Aside from that, I have noticed better reception in areas where I had poor signal before.

[Q] signal proble? :S

my defy sometimes lost the signal and GPRS,
especially after gamming :S
and every time while signal is gone,
the signal icon shown on status bar is freezed:S
i mean.. it shows full signal but no signal in fact
its so annoying that it make me miss many calls.....
i rely need somebody's help orz
what should i do?
im using cm7 by quarx and i tried to reflash cm7 before, but not works :S
I have experienced the problem when I first flashed CM7. After lot of frustration, I found that the sim card dose not fit snugly in the sim card slot. And after a drop, the sim card had moved from the contact. Removing the battery and setting the sim card properly solved the problem for me. Hope this helps. Another thing you might look at is the setting the right base band. And also select the proper network type in the test menu [dial *#*#4636#*#* and go into phone information and scroll down.] Sometimes this gets reset to WCDMA

[Q] No Signal, Factory Reset

Guys
any of you had any bother with your mobile signal?
I'm on Vodafone and from this morning my signal bars are empty and I have no mobile signal.
I tried selecting Vodafone and Automatically select from the mobile signal menu, never made any difference.
I did a factory reset of the phone and it worked great, logged into google, restored my apps etc and it was all good
Then 5 minutes ago the same happened again, no signal and nothing I do makes it come back on bar another factory reset???
I've tested my sim in another phone and it is fine, no drop outs, no issues, I hope it's not a faulty phone (
Any one else had similar or can think what would be causing this?
Thanks
UPDATE -
Happened again, no signal bars, no connection
so this time rather than a full factory reset I removed the apps I had reinstalled, which were Spotify, Facebook, Twitter, Tapatalk and Whatsapp, rebooted the phone and my signal is back to full strength again???
Could one of the above apps be the problem?, is that even possible?
Its got to be some software problem.. These apps cannot cause such a problem
thats what I thought.
I've left the apps off for now, and if the signal seems ok after a couple of hours I will start putting the apps back on one by one and see if anything obvious happens.
The only App I thought maybe could cause it would be whatsapp as it ties in with your mobile number.....I'll see what happens throughout the day
happened to me once, all I did was put it into airplane mode and then back out of it again, and all was well
Same thingg happened to me. I'm on tmo though. Its defective. Waiting for replacement
I take it you've all changed your SIM cards to be on the safe side?
My experience is that the signal does have a tendency to drop out in weak reception areas and is slow to pick it back up again. I'm on vodafone in the UK.
I'm on orange and today I had nothing but problems. Dropping signal and everything I am not sure if orange is having problems. Had a HTC one s before never lost the little H above the signal bars.
Should I look at getting a replacement sorted.

I'm having the same problem with T-mobile in the US. It seems to mostly be an issue for me in areas of weak coverage. A reboot or any other way of resetting the phone connection fixes it, but still...
Been happening all day. Even now I have no mobile signal and yet I am on here using mobile data.
Usually a full reset would bring the signal back for a while then it would go again. On one occasion putting it into aeroplane mode then back again worked, but only the once. It looks like I'm taking it back this weekend unfortunately.
i had this issue when i first got the handset on o2, but after a while and me putting the o2 sim in, it picked up signal, swapped out for my orange sim and hey presto started working fine. It's been like that for a week now, but last night the battery died when i was asleep and after a charge this morning, no signal again on my orange sim. I'm in work now so cant swap out for my o2 sim as its at home, but will try and borrow somebody elses sim to test when they get in the office later this morning, Very annoying!
same issue discussed here: CLICK
Just tried another sim, o2 this time. Same issue, so back to shop on Saturday. Question is do I get another one or plump for the sIII or an htc

Erratic modem behavior

At home, we have a Cel-Fi signal booster since T-Mobile reception isn't very good indoors. With the signal booster, there is full reception pretty much everywhere in the house. However, for some reason, my Nexus 4 running stock 4.4.2 keeps cutting out to no signal as shown in the picture (the phone is in the same spot in the house for the entire duration shown). This behavior happens with the 97, 98, and 33/98 radios. Does anyone have any idea what may be causing this? Everyone else in the home has no problems with the booster and I've even swapped out my SIM card but that hasn't fixed the issue. Thanks
