[Q] UK TMobile signal weirdness

Recently my signal is constantly switching from G, 3G and H (sometimes full bars with no signal icon). I'm at work so not in a new poor reception area. It'll switch even if I move the phone a couple of inches in one direction. Generally getting poor reception tho.
What I'm wondering if whether to speak directly with TMob or whether it's a) atmospheric issues or b) something to do with my Darky ROM flashed modem (BUJP5)
I have a sneaky suspicion TMob won't help if they discover the phones seriously modded.
It's causing me a lot of grief
Thanks in advance for any advice

Well, I guess I'll sort it out myself.
It appears that it might have been a couple of things; Juice Defender seemed to screw up reconnecting to 3G leaving me with full bars but no signal plus the Preferred Network Type was set to Unknown. I've now changed this to GSM/CDMA auto (PRL) and my signal seems to have stabilised (still a lousy strength tho)

Clue to problem board is littered with problems from one rom and thats it
.
Its the rom remove that before trying anything clean wipe and stock install .

Signal strength bars fluctuating

Hi guys, I just got my Incredible S yesterday, and I absolutely love this phone!! The only problem so far is the fluctuating signal bars. I'm not sure if this topic has been discussed here, but it seems to me that when I hold the phone...my signal gets weaker. When I put the phone on down..the signal gets stronger. Does a rubber or silicone case help as far as limiting signal interference?

Are you talking wifi signal or 3g signal?

I'm talking about 3G/H. It's such a shame. I really liked this phone, but designing the antenna on the battery cover is a huge flaw. What were they thinking?!!??

I also have the signal strength fluctuations. I have tried everything: changing the SIM card, changing operators (Swisscom and Sunrise), changing settings GSM alone, WCDMA alone, and GSM/WCDMA auto, and soft reset. The only thing I have not yet tried is a hard reset.
I wonder if somebody else has the same problem? The consequence of this problem is that often times the quality of the calls is lousy and/or the calls are dropped.
Please help me..

Have to say, my signal level is dreadful compared to my bog standard Nokia mobile phone in low signal areas, I get no signal on my Inc S while 2 or sometimes 3 bars on my Nokia. It's really spoiling an otherwise brilliant device. One thing I was wondering is if changing radio from the 22_M to the 27_M might help, anybody know what the difference between them is ?
and, data does not work over 50% of the time on gprs, but fine on hsdpa/3g/edge, don't know if that's also down to poor signal reception ?

I had the same problem with my IS. when the internet connaction GSM/WCDMA auto i had many unexeptable call ends. I put the internet connection to GSM only and every thing is ok. Acording to info i have the problem is in some operaters new software when the network type changes the telefone cannot change it normaly.

After visiting other fora, I have a crucial question to ask: is the reception problem (fluctuating bars, dropped calls, WiFi disconnecting) a generalised problem, or, rather, is my phone faulty, and therefore should I have it repaired?

HTC update the radio module immediately....

I also believe that the desire s has this same problem they are similarly designed devices now running with very similar software.
even though at times signal can be great without moving it can drop to nothing and I'll lose all signal, which I believe has caused me miss several calls as they've gone to voicemail rather than ring on the phone.
I'm hoping that an upgrade to the phones radio will fix/improve this over time (the optimistic outlook)

signal
its the antenna design =Fail , put it flat on a desk and dont hold it and watch your signal go up pick it up and its like an hour glass going down

I am now arriving at the conclusion that sound quality and dropped calls (and bars fluctuating) can be explained by a connection problem when using GSM/WCDMA Auto. The problem disappears when using GSM Auto. Any views?

Same here, but it is better on "wcdma only" either. I'm suspectinig it has issues only when switching between wcdma and gsm

[Q] Cell reception indicator constantly flips between "no reception" display and bars

[Q] Cell reception indicator constantly flips between "no reception" display and bars
I'm using the Xperia Z3 Compact on TMobile's network in the US.
About 1/4 of the time when I turn on the display the phone indicates that it has no cell reception:
1) The phone shows no bars of reception, and a red X over the bars
2) The lock screen reads "Emergency calls only"
However, within a second or two the phone appears to acquire an excellent signal and I get a full 3-4 bar display. All of the areas in which I use the phone are marked as "Excellent" on TMobile's coverage maps.
This also happens intermittently while I'm using the phone. I'm not sure if it's actually losing the signal or if it's just a software issue. I've never had it drop a call or cut out while I'm talking.
I'm getting only acceptable battery life from the phone (about 25% at the end of the day) despite light usage and conservative app installation, even though this phone has a reputation for excellent battery life. My theory is that this might have to do with the phone constantly disconnecting from the network and then having to re-aquire a signal.
Anyone else had this experience with the Z3C?

Hey mate.. I posted the exact same issue a couple of months back. I was experiencing this exact same issue.
I've had my LTE disabled for about a month now and haven't had a single drop.
Not sure if LTE is a dealbreaker but since my device is a business line, I can "suffer" with better battery life and slower internet if I'm not dropping calls. I've considered trying a ROM with updated radio firmware but figured I'd wait to see what the current Lollipop update does ('ll re-enable LTE once I install it and see if it repeats the same behavior) for my phone before trying a 3rd party system.
Hope this helps

Thanks! Really gratifying to know that it's not just my device. Seems like there's a strong possibility this is the issue since I'm on a MVNO that's only been on this LTE network a few months. I've flipped the device into GSM only mode and we'll see if it helps.

Dumb question how do i flip it into gsm?

Thanks!!!

I'm having the same issue as you have described. For now I've set the phone to 3G prefered. Looks instantly better. Signal strength is also better.
Provider: Simyo (KPN network) - The Netherlands
Edit - Issue solved:
I switched from the Lollipop Baltic ROM to the Lollipop KPN carrier ROM for The Netherlands. The switching is gone for me. Battery life drastically went up.

Any update on this? I just started experiencing this issue out of no where about 2 weeks ago. I'm not rooted or anything, can't afford to due to job security requirements and such.

Reduce 3G to LTE switch delay?

I've looked everywhere and tried too many solutions so I'm hoping someone has an answer here!
As most may know, phones will switch to 3G when LTE has little to no signal strength, but here's my problem with that:
My house has amazing LTE signal, yet several dead spots where I randomly lose LTE entirely.
These spots hit me, push me to 3G, then my phone has an extremely long delay before switching back to LTE, while my mobile Hotspot slows tremendously, lagging games to hell. It's torture!
The only method I've found is switching to LTE only, but then I receive no calls or texts, thus a raging girlfriend appears.
Hopefully someone knows of a way to remove the service switch delay?
Save me from the lag!

Major Call Drops on S10

I would like to share a peculiar trouble with my S10 that I purchased 8 days ago.
At my workplace, wherein I have been working for about ten months, I am now experiencing major trouble in calling with this phone - the person at the other end is never able to hear my voice properly - in every call!
But, outside of my workplace, this problem does not occur at all! Voice quality is amazing.
I went to the service center. One of the representatives immediately advised a factory reset and fresh installation of software from their system. I got that done, but the problem was still there. Very poor connection!
I went back and another representative gave me an advice which has solved my trouble magically! Now, the call quality is back to normal just like i get outide my workplace.
The advice given to me was to change the Network Mode from LTE/3G/2G to 3G/2G. He had said that this new phone has more bands than ever and that it is possible that my workplace environment does not support the new bands (sounds illogical). By the way, the signal bars still show 4G icon but not Volte/LTE like in the other network mode. (And my last phone, Mi 5, never gave me such a trouble)
Although the problem was solved, but i wondered that changing the mode from LTE to 3G will have a bearing on the data speed. I used Ookla speed test to determine that and yes, there is a major difference in download speed - it is less than half in 3G/2G network mode.
Can you please tell me if there is a trouble with my device harware or was the representative right?

LTE does require a much stronger signal than 3g and when you default to LTE the phone is probably just getting enough LTE to stay locked in to the signal. The LTE signal is getting knocked down in your building. Also HSPA+ will propogate better than LTE, even on the same bands.

Thanks for responding. In all this while I've done a lot of research. I managed to ask someone to come with their S10 to my office. The calls went through with this S10 without any hiccups whatsoever.
Also, I've been using the same network in this workplace on Mi 5 without any trouble. Also, there are many S9 and S8 users in my office. They have never had such complaints and they call on VoLTE.
Also, I tried two other networks and the problem persists.
Clearly, there is trouble with my phone. It is with the service centre now for diagnosis but they have been claiming that the problem lies with network in my area.
At the service centre there was another customer with Note 9 who complained of similar call drops but in random locations. The service centre simply did a fresh softwareinstall and sent him back.
My problem is that I will never be able to prove to them about call drops since the drops do not happen at the service centre.

I've had many occasions where I'm on the phone and the call drops. I try to pay attention to the screen as the 6T was pretty bad for that (I would face hang-up all the time) and it seems better with the S10 but I still get a fair amount of call drops. If I even attempt to hold the phone with my shoulder, it's almost guaranteed it will hang up as the proximity detector will enable the buttons.

Keep LTE enabled for data, but turn VoLTE off so calls switch to 3G/2G

Did you try to use a different sim card?
