Question for people who switched from Evo 4G to Evo 3D.
Is anyone else noticing markedly weaker phone/3G signal strength as compared to their old 4G?
Mine is showing next to no signal in placed that my 4G showed full bars, and it pops in and out of roaming in places where I previously had decent Sprint signal.

I am having horrible reception problems. I have to sit on a window sill to get reception at my apartment where my Evo 4g got atleast one bar. Driving on a major highway here in Rochester NY, l watched my phone have one or no bars all the way into downtown. Roaming has been turning on and off.
Went to Sprint Store and the Rf tested my phone and said everything was fine, but my phone still seems to bounce around signal strength wise and usually ends up with one bar or less in areas where I have never had reception problems before.
As for 3G, it was running really, really slow until I called sprint and did a factory reset which has seemed to fix the problem. I'll know later if it fixed the signal strenth problem as well.
Sprint store and RF test just dont sound like they go togehter.
Definately sounds like your device is having some issues with CDMA.
is the signal in wifi stable or is fluctuation like in arc?
what is the speed in S or is it bounded like arc to 65mbps?
one check?
WIFI connectivity is perfect with this device, no drops.
Haven't run a speed test yet.
Thanks you
Had mine for a day now and using wps setting with wifi the connection never dropped.
Is there any effect on the wifi signal strength when u hold it in landscape mode?i.e . when u have partially covered the the transparent strip in this position?
I haven't experienced any drops regardless of the position of the phone.
Don't notice any signal strength drop offs either unless I physically move away from the access point.
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 to everyone.
I would like to know, if you also have bad network coverage / signal with your phone.
After I cracked the display on mine I also had to change the small coax cable running from the middle rigth to the bottom antenna of the phone.
The signal strength is better than with the broken cable but also quite bad.
Did I receive the only "bad apple"?
I tried to check if the signal can be boosted with MTK engineer mode, but I am stuck.
Is it just me, my provider (o2/e-plus which is the worst in Germany, i can not have another one because of the policy of my business firm), bad settings, bad baseband, or just bad hardware.
It feels like the 1990th, but still without Nirvana
Thanks, Jens
I just got this phone a few days ago and performance wise I am very impressed. However, the signal reception isn't really satisfactory.
I live in the Philippines and my carrier is SMART. When I'm outside the signal is fine, 4-5 bars. But when I go inside buildings it becomes 1 bar and sometimes becomes no service (especially when I put it in my pocket) Also even though my sim is LTE capable, I never seen it connect to LTE networks. Only 3G and H+.
Have you guys experienced this problem? Is it a hardware/software bug? Or is it a defect?
