I bought mobile just two days ago.
I did OTA update so I can't see what was difference before.
Actual configuration is: Kernel 3.18.22 and fw 20161209.
When I am in the office I'm getting 3G!
Strange is, when mobile is connected to charger I can get 4G! Even if I do some network activity with charger connected 4G is still active. (Signal strange -117dBm 22 asu)
When I disconnect charger I still have 4G on the screen. But when I going to do some network activity it turns back to 3G! (Signal strange -68dBm 26 asu)
Do you have similar experience?
Is it any battery safe mode or just a bug?
Thanks for reply.
Only a theory:
The charging cable serve as extra antenna.
But yes, very curios, because it should not change anything!
Same here friend... this smarthphone have serious problems with 3G / 4G switching and connectivity... and i am loosing my mind about this.
probably i will buy another phone, but i am low on budget, first i will try probably MAD OS 7.1.2 build.
let's see

before but it seem the problem isn't about battery over heat after i got a brand new genuine battery, so i like to start a new thread.
I have pinpoint the problem to be more specific only limit to 3G usage. The phone will just shut off after using 3g outside (rogers) for sometime at least when phone heat up and it will go into shut off cycle. Whenever i turn it back on it would simply reboot itself once i did the initial unlock and keep doing so as soon 3g power on.
I would like to ask if anyone have similar issue with this and a fix? could the cause be baseband ?
I never experience shut off if i am using wi-fi in my house or on a hotspot outside. No matter what i do on the phone.
Hello guys..i bought a RAZR XT910 before about 3 weeks and i didnt notice any problems with it at all..its battery life the way i organised it with smart actions is very very good, better than my iphone 4...i have as well those black marks on the screen on low lighting and black pictures but i dont mind this either..as u can almost never see it...my problem is my weak wifi signal..i never noticed it those last 20 days as i have been working on my phone mostly on my computer desk so the phone was next to the router..the only place my phone gets 4/4 in wifi signal its when its next to the router..at 1 meter distance the signal gets 3/4 strength..at 5 meters 2/4 strength and at 10 meters the signal its lost..and this is only when im at the same room that has the router..if i go to another room the signal gets lost..especially when i close the door...i never had any wifi problem with my previous smartphones and i even had wifi outside of my house...please help me here..im quite desperate..what shall i do? return it and demand a replacement? ask for my money back? is there any way to fix this?
I don't have that problem but I'm wondering if you get it with other networks? Also have you tried resetting your router?

yea i get it with all wifi networks...for example my university, work, home..etc
Hmmm. I just ran the Speedtest app and got 12Mbps download over my wifi. It would be interesting to try that a few places and show it to VZ. Maybe they can test it on their network.

Get wifi analyzer and see if you have good signal. I notice that the Wi-Fi graphic is conservative.
my RAZR was having trouble operating on WPA2-Personal secured wifi network.. so i changed the wifi settings to WPA-Personal with TKIP and the problems are gone so you might wanna try this before you RMA.
Mine had problems with dropped and weak signal which turns out to be because I had Bluetooth on as well. If I turn bluetooth off wifi works perfectly
My WiFi reception is appalling. It only see's my home network where as my three year old HTC Hero is seeing seven!
With my package I have the ability to connect to BT Openzone hotspots around the UK.
Not much use if you can't go more than 15ft from a router without the connection dropping!
Bluetooth is off and I have tried several WiFi analysers from the market, all show a very weak signal.
Hi
On mine, yes the wifi signal (bars) are showing less then with htc desire, but I can connect without problems even the router is on the second floor and I am siting on the first, so reachable from the whole house.
I do experience, that it takes a little bit longer to find the wifi as with the desire, but once connected, works just fine.
I do not experience problems with hidden networks. Mine is not broadcasting the id, still connection is stable.

The bars on mine seem less than what the signal actually is. I connect to my home wifi just fine, from all over the house. I also connect to work's wifi from what seems like the same distance as my previous phone (Dinc)
i'm using d-link dws-125 (usb router)
when i connect and start using internet, the network disconnects in a few seconds. then it connect again and the same... etc.
please, help!!!
same problem here, hope a solution can be found as the phone is unusable in its present state
The "single ball" is enough to achieve 10mbit at my place, however, I upgraded my firmware to OpenWRT and now I get two full lines and the "ball" in the bedroom.
Stock netgear firmware is.. Incomplete. :S
Wi-fi back
Hi everybody,
I have the same problem mine is a razr from france even if i use it in italy, i found that when haveing the phone in the hand the signal gets very worst, if i hold the phone from the edges not in the hand the signal is much better i gain two signal bars, the same happens if i left the phone on the desk, the signal gest very good, as soon as i take it in the hand the signal gets bad, a kind of antenna gete from iphone....
hope this helps somebody
used to have this issue with weak wifi signals, but after installing the 85P radio update, it's gotten a bit better.
Hi There!
I have my Galaxy S3 and I have two locations (Home and Office) both with Zyxel WAP-3205's running the latest firmware.
I can't stay connected to either.
Essentially if I switch off WiFi on the phone and then on again, it connects, gets an ip, will work for a few minutes or maybe less and then seems to drop the connection. Only switching WiFi off and on again fixes it for another minute.
I am running Stock VFNZ firmware.
Home is running Channel 1, can't recall what work is.
Anything I can do to troubleshoot?
I am also having a similar issue. My wifi disconnects every hour or so and when i am in call while using bluetooth my wireless disconnects like crazy.
Mine turned out to be a faulty GS3 which was replaced and now everything is fine.
My dealer refuses to replace mine even tho I can replicate the problem easy and consistently. My only option now is send this off to Optus which is pathetic.
My i9205 have generally poor signal compared to my note1. It doesn't seem to make any difference to turn of LTD. I have not experienced any call dropping, only referring to the displayed signal. My note shows full signal while i9205 shows minimum signal. And in battery usage the "Cell Standby" is quite high and normally with 10-20% "Time without signal" even if I have not noticed any time without signal.
Anyone have similar issue ?
I have the Mega GT-I9200 and experience spotty signal as I drive around. I am on T-mobile in New York. Within a 15 mile radius in New York City my signal will fluctuate between HSPA+, Edge, G (1st generstion GPRS), and sometimes complete loss of both data and cellphone signal. I think the issue is I might need a modem to be ported from a t-mobile device to give me a consistent signal. Not sure if anyone could do that or if there's even a t-mobile device whose modem would be compatible at this point.

Yep! I'm definitely getting this too. The phone very rarely shows the full 4 bars of reception, and in low signal areas (1 bar or less) the phone starts flipping between GSM/WCDMA (UMTS) constantly, giving very poor reception. Also, signal strength in general isn't as good as my nexus 4 was. I sometimes am unable to reliably maintain a signal at all in areas that I know my N4 could reliably hold 1 bar of strength, with the phone disconnecting from the network completely and then reconnecting all the time.
As I'm in the UK and without LTE anyway, I've switched the phone to WCDMA mode only, which has helped though the phone now just flips between HSPA and HSPA+ when in poor signal. Its certainly much more usable this way at least.
On the upside, yesterday night with 3 bars reception I was consistently able to get over 15Mbps download, with my best result of nearly 19Mbps! So it doesn't look to be a hardware issue.
I'm speculating wildly here but to me this looks like a SW issue in one of two areas: signal strength isn't being reported correctly (too low), causing the phone to take action to try and obtain a better signal (by flipping to a lower bandwidth protocol or disconnecting and trying to detect a better macro, for instance) when it isn't really necessary OR maybe the phone is just too aggressive in switching from HSPA+ down to GSM to save battery.
Is there some way to take control of the mechanism, and try to force the phone to stay in hspa+, or to spoof a higher signal strength?
EDIT: This phone is packaged with very thin plastic wrapping over the metal band that runs around the circumference of the device. I accidentally left a lot of this wrapping on for the first few days. It may be complete crap, but I think my signal might have improved since I removed it all! I certainly seem to be able to maintain a connection in places that I wasn't able to last week, and maintain a constant (4-5Mbps) HSPA+ link in areas that I couldn't before...
Time will tell...
I have the same encounter, I have two sim cards belong to the same number one for phone and one for tablet. The one in Mega 6.3 give me three bar signal but the one in Galaxy tab plus 7" give me four bar signal :crying:
I am also having reception issues with my mega 6.3 I get worst reception than any of my other phones sitting in the exact same spot. I am on ATT in the US. I removed all the plastic around the phone. I am wondering if it is my APN settings. Hopefully someone can shed some light on this or there is something eles going on.
The Mega has an issue with the radio. I bought two of these an i9200 and i9250. Both Mega's would lose signal completely. I don't have the greatest signal here at my home, but it has never been an issue with any other phone such as Note 1 and Note 2 and many others. If you are in a weak signal area more than not, you may wamt to hold off until the radio issue is resolved with software or whatever. They were unusable for me and I re-sold them.

I have an i9205 and it's fine with the signal. I'm in the UK though
The big problem about this is that the phone uses much more battery when signal is low and using 3G. I can get 6-7 hours screen on time on one charge while wifi is on. But when using 3G with low signal I get 3-4 hours.
I hope this is a radio firmware thing, and not a hardware thing, so that it could be improved with updates.
so any updates?
Same problem here with my new Mega 6.3! My phone have only 1 or 2 bars signals while my brother's Samsung Grand has full antenna easily. It's very annoying. What should we do?!
Same ****ty reception going on with mine. I returned it.
I changed it too. New one is working fine.
hi. ah really? changnig phone u noticed a consistent improvement in reception?
but... i can say that i and my girlfriend, using a DIFFERENT SELLER...... we have the same problem of cell standby
I found that all phone models are inconsistent in radio reception, not sure why...
Sometimes the updates can do a little better, but I believe the hardware is the most limiting factor.
Maybe Mega isn't for you where you live, just return it then get another phone
i have poor signal Too
Any news or solution ?
Hi Guys,
I've had the Sony Z5 Compact for many years now and well I'm still not willing to depart from it just yet as it was a gift from my Granddad who sadly passed awhile back.
I've had awful signal problems for the past 24 months or so, at first, I thought it was the network THREE but since then I've tried O2, and Vodafone. It didn't so much bother me at the time as THREE had WIFI-CALLING app which they recently retired, so I went Vodafone thinking that would resolve my issue, it didn't. Now I know the Sony Z5C generally use lower bars than Samsung but this issue is not to be confused with this. I've had weak signals on 3 different networks, in good strength areas as I've tested the Sims on a Samsung A50 with no problems. I can live with a weak signal but the constant drop outs, unable to make calls on the 'first attempt and missed calls is frustrating me to say the least.
I've followed Sony's advice: Factory Reset and a Software Repair using the Sony Companion software with no success. I'm starting to think I have a hardware fault, I've heard some people saying it could be the antenna wire, but do these even go faulty? I know the Sony Z5C runs hot, but to break the cable? and I know the iPhone 6 had IC issues that caused signal problems, so thinking could it be that?
Here is the signal strengths of each of the modes:
GSM_ONLY [ -75 dBm 19 asu | 200 Kbps]
WCDMA_ONLY [ - 79 dBm 17 asu | 9Mbps]
LTE_ONLY [-97 46 asu | 20Mbps - but can't make a call...]
Now I've been told the default mode, and the mode I should be using is LTE_GSM_WCDMA but when I select this, this happens:
Mobile reports 4G 3/4 signal bars, I go to make a call and then the 4G bars drop to 0/4, then I get 4/4 Bars with a H (not sure what mode this is), If I'm lucky, it connects, but most often it just fails, sometimes it will even go to 4/4 bars without the H (again not sure what this means).
The worst thing is receiving calls, my phone will ring, and when I answer, I have to wait, like 5-10 seconds for the call to connect, but most of the time, it fails!! I'm not sure why I can download at 20Mbps over LTE over the calls just don't work! its bad outside too, other phones do not have an issue in this area, we have good LTE here.
What else can I do behinds factory reset, and use the Sony Companion software? is the phone faulty? would that be the IC, or Antenna?
