Weak Radio? - Verizon HTC One (M8)

am I the only one experiencing a weaker radio in this phone? I've had a bunch and with this phone in my basement I only get 3G (4G with every other phone) I'm also getting alot of dropped calls in my area. I know it's not just the phone as I've tried 3 and they all do the same thing. Is there a new Radio to flash for better service?
Also is there a way to remove the cover? The camera seems to have a haze behind the cover, it's never been dropped/spilled/etc.

I wouldn't say the radio is the worst reception wise but IT SUCKS with the 3g/1x/4g sometimes when I'm traveling I'll enter a 3g or even 1x area and when I get to a 4g area it's still stuck in 3g or 1x until I cycle airplane mode off then on again, drives me nuts sometimes. As far as signal strength it's on par with my galaxy s4 but not good as my old Droid or note 2 I'd say the radio is average but the 3g handoff thing is very annoying

We're working on that all over the nation. Cdma or 1x will be totally phased out over the next year but how many of us are going to have m8's in a year? Every Ericsson and Verizon approved contractor is out there killing it right now trying to fine tune the network.

When I first got the M8 on stock..I thought the radio was quite good. Once I rooted/S-Off and went to Viper ROM...still was quite good. THe last few eeks to a month..I've noticed the radio acting very oddly. In normaly strong 4G areas...it will just drop data and wont reconnect until I switch the mode (I use the old T Bolt LTE On/Off app) from CDMA + LTE/EvDO Auto to LTE, CDMA or just LTE ONLY to force a reconnect...but even then it will get stuck on 1xx in a strong 4g signal area. At that point only a radio off/on gets the 4G back.
Radio seems to be very "sticky" and stubborn once it gets off the 4G LTE these days. (I am in NJ....so the whole state is bathed in LTE)
Not sure what to do...it isn't per se terrible...but it is getting annoying.

Not as good as my iPhone 5 but much much better then my galaxy nexus.

Before the M8, I had the thunderbolt, rezound and M7. The M8 is on par with all of those phones. I haven't noticed any signal difference. I'm in a pretty good 4g coverage area though. So I'm sure that helps.

I am having very similar issues but I am in California and very slow 4g speeds at times in areas that have always been pretty good (10-30mbps+). Now I'm lucky if I get 5 and sometimes it's so slow, speedtest fails with communication issues. Xlte areas don't seem to be having issues though as I consistently pull well over 70 down sometimes passing 100+. Seems like only the band 13 lte is the problem in my area. It is quite annoying and if they don't fix it soon, they better plan on crediting some of my bill because I can't even use my phone at work anymore.

Yup..exactly what I'm experiencing. Maybe with the XLTE implementation they're having handoff/communication issues with the older 3G/4G network.

Help ! G2X - Poor Reception ? Anyone Else ?

Just got the G2X today.
I'm having extremely poor to no reception at work.
All TMO phones I've used (G1, G2, N1, NS, Mytouch, Mytouch 4G, Galaxy S 4G)
in the past have random reception problems, mostly what I'd say is passable reception at work (in and out of steel buildings).
This G2X is the worst yet.
TMO service walked me thru putting a new sim in and and all.
But it didnt help.
It jumps back and forth from 2G with 2 bars to no service at all.
I didnt like the Galaxy S 4G but it got better reception.
I like this phone, vanilla and all.
Anyone else having this issue ?
If not its going back to TMO.
I got mine this morning at 10 and I have been having great reception! 4 bars with the 4G! And I came from the Samsung 4g also!

How do you know if you got 4G, I got the 4G symbol but network connection says utms and I mainly get around 3mb download on speedtest, but sometimes it goes to 7 or 8 mb down...but still says utms, I thought that was 3G. thanks!

I have had great reception with the G2X. Better than both the G2 and MT4G.

I love the phone, but the reception isn't very good in my house. The nexus s had better reception.

G2x's reception is on average about 5 to 10 dB weaker than the MT4G that its replacing but I have full coverage everywhere I go and at home I just use wifi calling so its a non-issue.
I live right by an air force base and I'm sure their signals interfere with cell reception. at&t has tons of towers out here and I had to switch because of the signal interference being so bad.

I still have the MyTouch 4G and Galaxy S 4G and they both have much better
reception than the G2X does.
I'm pretty disappointed.
I'll probably end up returning it and going back to the MyTouch 4G
(I didnt care for the Galaxy S 4G....200mb internal memory what ?).
Especially since its being reported the Sensation is hitting beginning of June.
There are like 6 or 7 "poor reception" threads in here.
Does that mean this is now definitely a known issue ?
All I got was them walking me thru putting in a new sim.
Nothing improved and the tech said oh well it must be just the area you are in.
And this was after me telling her the MyTouch 4G and the Galaxy S 4G didnt
behave in this manner !
I'm leaning towards returning the phone at this point, but I'm going to wait
a week or so and see if any software updates addressing this are forthcoming.
I had a great reception with my G2x. Had 4G throughout the day both at home and office. And on the way from between home and office too.
Unfortunately had to return it for reboot issues.
I am getting only umts. The device shows 4G but still only umts. I have installed new sim card and had it reset on the network and nothing changes. Even my Vibrant will show hspda when in 3g areas but not this phone so far. I have called CS 3 times and finally they have agreed to send out a replacement phone. I also have had random reboots ( it reboots but reboots right back up to the app you were running before the reboot.) and after speaking for only apporx. a minute the phone feels like it will burn your ear., I really want to keep this phone but if the replacement is the same than I will just send it back and wait for the SGS II or the Sensation. Really is a shame as there is so much I really like about it.
Got the phone, what gives. Connectivity sux, shows like 3 bars and 4g but the internet is slow and spotty. What gives? My HD2 runs just fine in the same spot.

I'm not getting any signal issues. My signal has been working great. I'd say return it man and get another one.
No 3G At All ! Whats Up With That ?
Definitely has an issue.
I've never seen it get 3G on this phone.
Only 2G or 4G.
I guess I will be returning the phone.
I really hate to, I like the phone.
But there is definitely something wrong with it.
My G2X has the best signal I have ever had with a T-Mobile phone. I keep a data signal in more places than I did with my Vibrant.

My signal is great, but I'm only seeing 2G or 4G. This does not surprise me, I'm in a HSPA+ area. Why would I ever see 3G?
I can't take the reception jumping from full 4G down to 2G constantly. I ordered the Nexus S and I'm not looking back. Even without support for 14.4, SAMOLED and better service will make up for it.

FWIW, I came from a Nexus S and think the reception is quite a bit better with the G2X.
If you have reception problems you can try 2 things:
1) Go into your mobile network settings and change your network mode to GSM/WCDMA if it isn't already selected. Then click on network operators and do a search. You should see T-Mobile UMTS, T-Mobile GSM and ATT GSM. Once you see the networks it finds, click on select automatically. Before leaving this menu, make sure you click on data roaming. Don't worry, you won't be charged unless your internationally roaming.
2) Swap out your SIM card.

Did all that the 1st day (4-20-11).
Finally returned the phone today after testing the data connectivity
at work today with the MyTouch 4G versus the G2X.
No problem with the MT4G but the G2X had horrible or zero internet.
I will post the results with a new phone tomorrow.
The rep said they just got in a new batch of phones.
I hope the exchange has fixed the issue.
Its mostly wifi hotspotting that its really evident.
I want the phone to work because its the snappiest phone I've ever used.
Maybe it could be the area you are in. Both of my G2x and G2 have solid 4g signal.

G2X Reception

I Live and work in areas that should be 4G according to T-Mobiles coverage map. At work, I'm lucking to even receive a 2g signal and never get a 4g signal at all. At home, I can only get 4g if I select WCDMA Only and don't touch my phone.
I've noticed that my 4g (WCDMA) signal seems to range from -70dBm to -109dBm. As far as GSM I don't know what a good signal is, but I know I loose my signal at about -98 dBm. Interestingly enough, it will go from -85 dBm to -101 dBm in GSM just from me picking it up.
I'm wondering if my phone is getting good reception and if exchanging it might help the problem, but I have no numbers to compare this to. Does anyone get a better WCDMA signal than -69 dBm or have a good signal strength over -109 dBm. Does anyone know what a good signal should be?
I have seen some threads on reception but there are never any numbers to quantify this. To see your signal strength go to phone settings; about phone; status; signal strength.
Any input is appreciated.
There is an app to test for towers and reception . I found I'm not close to one.
Figures.

Thanks,
I have Open Signal Maps installed. Lots of good info. According to the app, I'm a 217 meters from a tower. It actually shows 3 towers within a quarter of a mile. Maybe it's signal overload....

I would have to agree. This thing can get great to little signal. It seems to have trouble with the in between.

I also have horrible reception with this phone.... my sga4g had a solid full bar 4g signal all the time.. I thought maybe having my g2x rooted and running a custom rom might have something to do with it so I unrooted and went back to stock... but still no good... my phone can sit in one spot and I watch the signal go up and down 4g 2g .... so I locked it to wcdma only .... It stayed on 4g bars still go up and down but now it will just lose network connection... I called Tmo support today and supposedly I'm in an area that has great 4g coverage .... so they say they put in a service order and to stay on 2g for 72 hours and then pull my battery, put it back in and see what happens... love the g2x but starting to regret giving the wife my sgs4g...

Mine does pretty much the exact same thing inside the house and I'm also in an area that should have good 4G coverage. I think the radio is just bugged and hopefully the update(s) will fix that. Good thing the phone has wifi calling.
Interesting. I was looking for a phone number today to call T-Mobile, but their site wasn't working (kept getting no connection). I wonder what staying on 2g is supposed to do. Let me know how it turns out.
I have the same issue! Constant switch between 4G, E and x!
I talked to T-Mobile and they worked on the towers or so they say! It's gotten a lil bit better signal, but not much and not sure if it's because a custom rom!
Thinking about doing an exchange!
Would an UPDATE FIX THE RADIO? Or is it faculty hardware?

It could be faulty hardware, but it could just be a software glitch in the radio baseband/drivers. If a radio update doesn't come with the initial software fix, I'm pretty sure the Gingerbread update should include one.
I too have TERRIBLE reception with the G2x. I'm coming from the HTC G1 and in spots that I used to get great reception with that phone, my G2x bounces all over the place from 4G to NO signal. It's driving me insane that it doesn't stay constant. I thought maybe it was just the towers in my area so I put my SIM back in the G1 and it never lost signal. I put the SIM back in my G2x and set it in the same spot as the G1 and it lost signal twice and toggled back and forth from 2G to 4G within 5 minutes. Hopefully there will be a radio update to fix this issue and that it won't be faulty hardware.
I absolutely LOVE this phone even with the flaws.. i just hope they fix the flaws soon.
I get pretty good reception, though at work I tend to bounce back from 4g and E, but I'm in a building that kills reception. Personally, I think it's the modem. I bet once we start getting newer modems, it's will stop this, but probably at the cost of battery life. My old vibrant got about the same reception, so I don't think it's hardware.
The Tmo tech told me to stay on 2g because my phone seems to be keeping a good consistent 2g signal... its just in the 4g that it doesn't hold a good signal.... I also kept bringing up if she thought that maybe a software upgrade might fix the problem but she didn't even acknowledge that I said anything about it .... I also told her that I read somewhere that for some reason T-Mobile should have given me the sim card that came with the g2x and she said that wouldnt make a difference because i just switched sims when i bought the sgs4g a few months ago and she then gave me free wifi calling...

Replacement Phone
Just an update. I went ahead and got a replacement phone to see if it fixed the problem. The new phone behaves identically. Also, a Samsung 4G user just moved into my office building and he gets 3 bars, which is what i get till I pick the phone up. The thing that bothers me the most is that it will loose so many dBm (bars) when I pick it up.
Does anyone know if a phone cover will fix this issue.

Anyone having issues with signal constantly dropping to 2G?

My wife just upgraded from the MyTouch Slide 3G to the Slide 4G. The 4G is constantly dropping to 2G so obviously the data speeds are terrible. Her Slide 3G usually always stayed in 3G in the same areas the 4G is now dropping. Anyone else experiencing this?
Did experience something like this at a friend's house.
Sounds like the problem that the one of the reviewers of the Sidekick 4G was having (ping-ponging between 4G and 2G). Not everyone was having that problem in the wild, though. Could be a coincidence that two recent physical keyboard-based 4G phones are having trouble holding their T-Mobile HSPA+ connections and skipping the 3G alternative, though it could be a bug with T-Mobile's HSPA+ at the tower or phone level. I don't know know the protocol rules on the handoff between 3G and HSPA+. Some reviewers have reported lower data rates than expected with the Slide. The Sensation supposedly has a death grip issue, so maybe there's a variation of that with the Slide (due to a different landscape hand position using the physical keyboard) resulting in 2G connections. Could be temporary capacity issues with your wife's local 3G/4G towers. Is this a constant problem or worse at different times of the day? I remember a few years back reading a report on 3G mobile streaming usage experiments in Europe that it only took like 8 people streaming on the same tower to saturate the tower's 3G capacity. Of course, the number should be higher with HSPA+, but just wanted to point out it is possible for a tower to get overloaded. Keep us posted. This is the kind of stuff that will determine whether I get the Slide and stay with T-Mobile.
I'm in MD and I'm constantly having this issue in my apartment. One minute I have 4g and the next I have 2g and it wont switch back until I restart the phone. I wont even be holding it and i see the issue. Dunno, at least I have 14 days to bring it back.
Had same issue with my sensation. Try going into settings and switching to just wcdma as opposed to it picking between gsm/wcdma. It is under wireless and mobile settings. That is assuming you are in a good 4g area. It will not show 3g
Sent from my HTC Sensation 4G using XDA Premium App
Well i saw this happening on the 1st floor of my house. But it was in a hallway away from the windows. but when i moved it came back to 4g and stays there. I think it has do more with the tower and whats available in your area.
Should I ever see 3G on the phone? Currently it is only ever in 4G or 2G. I notice the manual mentions 3G also though. I was assuming it always said 4G even if it was really 3G, but now I'm not sure. Has anyone seen 3G at all for their signal? I'm wondering if there is a setting wrong on the phone.
For those of you that don't have the network settings, go to the market and download an app called Network, it's free. Scroll down to set preferred network type and chose WCDMA only.

This issue is the phone itself. This is a verry buggy phone. Coming from a family g1 plan and were very excited but these phones have issues. Cant wait for root. Neways i know the 2g issue is that it gets stuck and u have to reboot. For ex. I tested in cordelane ID in near costco. Full 4g bars. Had 2 mt4gs's. One phone was in 4g and the other was stuck. I tried the old g1 trick they had in the beginning switching in and out of airplane mode. Did not work. Rebooted and it worked fine. Many other issues like all the time on both phones the widgets get stuck. U must slide to next screen than go back and widget works. Like i said i have 2 phones so i can troubleshoot and feel confident its not a glitch with a particular phone, etc. These phones suck.

Sprint's "network vision" and their excuse for terrible 3g

I have called Sprint on their BS and their horrible 3G.
Evo Shift = EVDO Rev A
Photon Q/iPhone5/newer phones = EVDO Rev B
Ping time on Photon Q = 800ms+ latency
Download speed = 0.02Mbps
Evo Shift = ~300ms latency
Download speed = .5Mbps
http://community.sprint.com/baw/thread/99267?start=360&tstart=0 <-- iPhone5 users having the same problem.
I switched back to my Evo Shift 4G. Apparently every tower is "down" in my area while they perform the upgrades. OVER IT.
Link above spells it out

One, EVDO Rev B, last I checked, is not on the Photon Q or any LTE phone other than the iPhone 5. Two, EVDO Rev B IS NOT AND WILL NOT BE DEPLOYED BY SPRINT OR VERIZON. All phones connect to EVDO Rev A.
Those speeds and pings are highly varying, make SURE both phones are connected to 3G (EVDO). It seems the Photon Q is connected to 1xRTT rather than EVDO, while the Evo Shift is connected to EVDO.
Yea I've been contemplating returning my Photon Q as well (still have a few more days in the 14-day return period for Costco) or selling it outright. I wish I had made the decision before last Friday when I could have picked up a GS3 for $50...
I have my Evo Shift on craigslist for sale, and thus returned it to stock, but am thinking I may unlock it again, try out CM10 on it, and if it runs well, switch back too. LTE would be nice, and even though I'm in the Atlanta metro, and get LTE speeds driving around, it seems to have dead zones at my house, my buddy's house, my wife's school, and anywhere else I might have the opportunity to use it. I was hoping some of the development would help fix these issues, but I guess I'm too impatient to wait lol. One of the last straws was going to watch a video on collegehumor that wouldn't run on the Q, even with Flash 11.1 sideloaded, but runs fine on my original HTC EVO (which also runs CM10).
Dunno, its a hard choice... the keyboard is really nice, and I'm excited for the free vehicle dock, and the dual core 1.5 is pretty sweet, but there are just too many issues with the thing...
To me the downside of Sprint's network is that the connection seems to drop out often, resulting in the inability to load data at that instant, and probably battery drain... i would think anyway. Does anyone else notice the connection dropping and reconnecting a lot? I felt like i maintained a much more steady connection on T-Mobile's network. And yea, i find Sprint 3G to be pretty slow.
But in the few times i've had strong LTE, i've had the fastest speeds i have ever recorded anywhere!

Yes, the Photon is NOT getting Evdo (whatever rev) even though it says it does. Both stock and post OTA.

I've noticed the exact same thing. When I'm on 3G, the data is fairly regularly just dropping for a second or two at a time, so anything that requires a constant connection (like IRC) will crap out. The few times I've been in 4G, mostly in silicon valley, I've gotten ridiculously fast speeds. Last time I ran a speed test it was like 36MBps down and 20MBps up. I never saw those speeds with Verizon (but that's likely because so many more people were actually using Verizon, too)

yeah the dropping connection is terrible, and happens even in a real strong 3G area. could it have anything to do with looking for LTE, or being on the edge of an LTE zone, or just the fact that the whole network is in flux? hopefully it's only temporary 'cuz it's pretty bad... seems real slow too, especially on downloads.
yeah, my record speedtest was 37 MBps down in LTE! i never got 20 up tho. yea, there can't be too many people using Sprint LTE yet, but i've been reading some forums on the site s4gru.com, and supposedly Verizon just raced to cover the nation with LTE, but didn't rebuild their entire network like Sprint is doing. who knows, but at least Sprint LTE seems promising.

That is a bug in 77.8 (drop data when changing network mode)
workaround: turn on airplane mode, turn off, or reboot phone.

i think these are actually 2 different things, i've been seeing the signal drop/reconnect ever since the original software version. after the update, the 3G icon will disappear(like after a phone call) and won't come back until you toggle airplane mode or it drops and reconnects on it's own(which seems to be often!). but if your 3G icon disappears and you have bars, try and you should see that you can still load data, so i believe that bug since the update is more of a cosmetic thing. at least that's how it is for me, and others have said the same on other forums.
Here's a screenshot where i have no 3G icon but have a perfect data connection!

yeah the dropping connection is terrible, and happens even in a real strong 3G area. could it have anything to do with looking for LTE, or being on the edge of an LTE zone, or just the fact that the whole network is in flux? hopefully it's only temporary 'cuz it's pretty bad... seems real slow too, especially on downloads.

You're right, that issue actually does have a lot to do with the phone wanting to search for LTE, or trying to prefer LTE when the connection is very weak. The solution? Turn off LTE when you're not in LTE coverage. Not the most elegant or pleasing solution, but that fixes it.

Yeah, that could be it for me. I switched to CDMA-only a few hours ago and haven't seen the signal drop out once. I'll keep an eye on it tho to make sure. It seems like LTE is creeping in around where i live, so my phone may have been wanting to connect but was just out of range of it.

3G Issues

First of all, my LTE works fine, this is only an issue with the 3G radios. Basically, I often have issues with 3G actually sending and receiving data. When it does, it is slower than 1X for me. It drains the battery at crazy rates such as 20%/hr with little to no use. This has happened regardless of rom, although now I am on the stock f1 update and unrooted. I bought this phone used so there's no hope of a CLNR. I've had it "fixed" by samsung twice and nothing has changed. Any ideas? I have an upgrade but I'm waiting for the One or the 5S and REALLY don't want to use it on a phone I wouldn't be happy with.
Same exact problem here. 4G works fine. 3G is essentially useless. Often when it changes to 3G, I wish it would just go to 1X so that at least it would be functional. I've never really found a solution. The other day my phone was in 3G and I tried to send a text msg with a picture. It took almost ten minutes. Completely useless.
Friends with 3G Verizon phones never have any problems. They always get a solid 3G connection. I used to be with Sprint (useless) and set my Evo to roam on Verizon because the 3G was so much more responsive and quick than Sprint. Not seeing that with my S3.

Yeah none of my friends have issues either. My friend with her iPhone 5 was using it next to me and it loaded pages in just a few seconds, still slower than 3G, but mine took almost a minute.

Forgot to mention... My wife's also got an S3. Mine's rooted with CleanROM and LK1 modem. Her's has the latest update. She has the same issues with 3G. She also had them on MB1.
Fortunately my phone doesn't flip over to 3G often. But when it does, I just stick it back in my pocket, because it won't do anything useful until it switches back to 4G.
I've never found the answer to this problem, but I'd really like to. I understand that this is a 4G phone, but it should be able to fall back to 3G with no problems.

FYI, I just tried AOSP for the hell of it and data speeds are much better. Too bad it seems a bit buggy. :/
nvm, speeds still absolutely blow
i have a network extender and most of the time I can't send pic messages..piece of ****...ive tried multiple basebands...im convinced its the phone

Theoretically AOSP ROMs should have absolutely no effect on data or voice since they don;t touch the radio firmware.
I was in a 3G zone this evening and did a speedtest.
23 kbps down. It died when trying to run the upload portion of the test. Friends with regular 3G phones routinely get 800 kbps - 1200 kbbs down.
I agree. It has to be the phone. And given that it seems to happen across multiple radios and only to some people, it's probably hardware related. Doesn't matter when I get 4G. Sucks when I can't.
I'm going to be at camp for a week soon and I only get 3G there so I'm strongly considering buying a used 4S until a new phone comes.
I have 3g signal in the house.. wide open all bars with a network extender..I go outside to get 4g, then it will send pic messages. dumbphone

I don;t think its a Samsung problem, more like a Verizon wide issue. If you look in the verizon user forums, all the Iphone and HTC and Moto folks complain about the same things.

I don't think so. Not only are they not complaining about just 3G, my friends' phones work fine.
Not only that, but my GNex I had before this somehow consistently had 2 mbps dl speeds on 3g.
Friends on Verizon with 3g only phones get excellent speeds where I am at. Verizon 3g is not the problem around here. On 3g phones, it is fast and responsive. When switching from Sprint, I went with Verizon based on the quality of its 3g.

I thought it was just me been having the same problem. Suddenly no 4g at home and 3g is no good. Good thing I have the WiFi.

Too bad you have to rely on something else that you pay for independently for your phone to be able to do its job. These phones should work on 3G. I have to imagine that there are some who don't have 4G that have to rely on 3G. Maybe they just don't get this phone, or get it and return it?
