Nexus 4 drops all service when entering HSPA+ area

Hey guys lurker here finally registering to get some help.
I have a nexus 4 with T-Mobile. I bought it unlocked through Google and have it on the same plan I had my G2 on.
My problem is every time I get into a HSPA area my service just drops. Like completely drops. I cannot even make a call. It will come on then off then on then off. It makes the phone useless. When I'm on edge it's perfectly fine.
I went to T Mobile and got a brand new sim car and that did not help my problem.
Much appreciated any help I can get.

Factory reset first and see what happens.

That happens when the radio on the N4 switches between 3G and HSPA doing a factory reset won't affect the radio. In other words its the carrier coverage in your area. Try Straight Talk with At&t

I've got a Nexus 4 on AT&T and i've got HSPA (no +, i've checked in settings). It seems when my phone switches between towers i lose service until i go in and select AT&T from a list of available networks. On other phones in this area i always have Tmobile and AT&T, but with this one i'm getting two AT&T's. I usually select AT&T, but the last few days i've tried selecting "automatically select network." It doesnt appear to have made any changes. Just wanted to see if anyone had any ideas before i factory reset this bad boy.

Factory reset, reflash of the stock ROM using the nexus toolkit, unroot and custom Roms cm10 and paranoid android. Nothing has helped my issue. I have the LTE plan and the WAP APN gives me hspa+. Still getting a signal drop every time I move more than a mile or so.

Doubt anyone is even watching this, but i called google and the rep says it sounds like a hardware issue. Getting a warranty replacement.

[Q] 4G issues

Hello, i am unable to get 4g on my g2. It is international version. Any ideas on how to solve this? I have alresdy called my telco and requested forb4g to be on. Unfortunately still no 4g after 2 days..

Same problem with my d802.
No clues how to fix it..

My friend recently had an issue with his 4g cutting out. Airplane mode being toggled on and off seem to bring it back, but only for a short amount of time. Finally found a thread on VZW forum of people having the same issue. I'll link to it when I find it again...
Come to find out it was the sim card. Got a replacement and had solid 4g with no cut outs. Unfortunately my friends G2 screen died the next day so he couldn't reap the benefits lol

Hey guys- I'm having this same issue, on my D801 with CM10.2 and DarkPA (tried both). Started yesterday evening - my phone automatically switches back to GSM/WCDMA preferred no matter what I pick. It's only picking up 3G/H+. I'm in the Chicago area.
I called TMobile and they gave me some BS about it being my tower, but also software issue, etc etc. The guy was just saying things. Still no luck. I am going to go to the TMo store today to see if a new SIM card will fix it.
EDIT: Turns out the cell tower near me is just being strange. I can walk down the street and get LTE, but when I walk towards my apartment the LTE dies and switches to 3G/H+. Weird.

Hi, thanks for replies. I got my 4G overtime. Happened to my brother as well. He waited 2 weeks before getting 4G. And btw, is H H+?

[Q] Dropping 4G LTE down to 3G

Hey, I don't know if this is a device issue or a problem with the carrier but, I've been dropping from 4G to 3G ever since I updated to the 4.4.4 NI2... this has never been an issue in my area before this update with any of the phones I've had. Anyone else having this issue or have any ideas as to why it's happening or how to fix it?
Thanks!

When I first did the update is set my access point name incorrectly, that's in more networks and mobile data.. Check that

I use it but not as my sms app... I've spoken with Verizon and they say it isn't their issue, Samsung said I could send the phone to them but it can't be a hardware issue because it only started after I updated to the NI2 firmware and modem.

So no one else is having this issue then? Cause Verizon is totally at a loss.

Like I said I had this issue when I first did the update but it was a setting in hangouts as my SMS to use a different APN

Verizon is a bunch of clueless idiots. I am seriously regretting my move from t-mobile. Verizon call quality, Bluetooth connections, and customer service are the absolute worse.
I wish I could help, but after doing some research it seems Verizon's poor signal quality and poorly designed networks are the cause of most of my issues. I have gone through two S5's and both are nearly unusable for phone calls. Network speed is the garbage. I am stuck with a pos phone and service for the next two years.

Seems like some kind of update in the area, after over a week I'm starting to hear complaints out of other phone users. Even a friend of mine who'd ranted about how if I had an iPhone 6 I'd still have 4G has now dropped to 3G while I'm starting to see 4G return little by little. It's been speculated that they are prepping for XLTE in my area and that could be the issue... little in the way of definitive explanation though.

Can someone post what there APN settings are, cause I looked around and the settings I see online do not match exactly my settings.

Settings, more networks, access point names. Unfortunately that won't give you any options. In google hangouts, settings, SMS, scroll down to advanced, access point names, that's where I had to change mine.

ditto
I'm having this issue here in LA. I chalked it up to the new NI2 modem at first, but I've flashed back and forth with NE9, NHA, and even NCG (original) and still seeing my 4-5 bars of 4G LTE drop mysteriously to 3-4 bars of 3G for no apparent reason. I'm even getting 1x at times. Also, to clarify, this is all while sitting still at my office in downtown LA.

The wall I have hit is simply:
Samsung offered to have me send the phone to them for possible repairs, which means going without my phone for at least 3 to 4 weeks...
Verizon, a corporate employee has confirmed that this is an issue that has been getting brought up more and more and they're working to correct the issue with the next OTA update. The problem is how random this issue is... why are some devices seeing the signal loss and others not?
It's a waiting game at this point.

No Service

So ive had the phone since launch and in the past 3-4 months i'd lose signal quite often during normal usage. But in the past month it happens pretty much every time I use it. Im on T-Mobile and I know they had some problem with the Nexus phones on their service back in August but I thought that would have been fixed by now. And then an hour ago I lost service and I cannot get it back at all no matter what I do. Im on stock 7.0 Nougat, non rooted. Ive tried all the resetting methods and what not but no go.
Any help would be appreciated, hopefully its not hardware related

I don't think it's hardware. I have the same issue on my device. Rebooting usually brings it back for me for a while

Same issue here... I RMA'd my device last week and same exact issue on this new device. I'm also on T-Mobile and I even got a new sim...

If you keep up with T-mobile news. They've been getting outages intermittently in certain locations.

It's gotten so annoying I can't even use the phone unless I'm on wifi. It cuts off service like every 10 seconds no matter how strong the signal is

I've attached a pic of the service menu.. Everytime the service goes out it always switched to the CDMA network even tho T-Mobile is LTE and what not

mines been doing this too, even wifi calling will go to no service sometimes.
I've only noticed it since I've been on benzo rom tho, not sure if its related.

OK so my theory was true, tested it many times.. looks like something in software or hardware of the 6p is making it switch from LTE to CDMA causing it to drop service and then I have to manually switch it back to LTE

I feel as though it's related to the cell towers. I spent the weekend in DC and I didn't have any issues whatsoever. I came home to Pittsburgh and within 30 minutes if being home I had my first loss of service

I'm in Atlanta where they should have good service but it's everywhere around here it happens

I just opened a ticket with T-Mobile so I'll follow up with whatever feedback they provide me withing the next 72 hours!

S10+ loses LTE and drops signal constantly

I've been having my S10+ on Verizon which I got in March, constantly drop from 4G to 3G, to noG. I didn't have this problem with my S8+. It appears many other people that having the same problem with not only the S10+ but other S10s on other carriers as well. Supposedly Samsung is supposed to release a software fix, but Sprint is also having people return their S10+s and get replacements because supposedly many of the first ones made have a hardware issue causing this. Anyone on Verizon or other carriers having similar issues and any update on the fix software or return and get new phone or otherwise?

What manufactur dates do you think were effected ?

Sounds like the same problem I had on TELUS in Canada. Took it to Samsung and they told me they had to replace motherboard. Fought with them like cats and dogs and they refused to give me a new phone. After waiting over a month for them to fix it, I immediately sold it and bought a Huawei P30 Pro. Will never have another Samsung Phone after that fiasco...

Not sure. Supposedly the first few batches but I'm not sure of date ranges. All I know is this has been the worst reception of any phone I've had and it happens alll over. Drop LTE and if i hit Airplane mode on and then turn it off it comes back. In fact I just had to do that right now to reply.

I had drop LTE signal issue, sometimes lte won't come back until reboot the phone but after do a reset network settings my phone works significantly better:good:

Am having the same or similar issues my internet is working all fine and out of nowhere i loose internet while still having full signal bar. I tried airplane mode and nothing seems to bring back the internet only thing that works for me is a reset am on AT&T

This seems to effect all s10 models regardless of the carrier.
I have a Verizon s10 plus that I pre ordered.
My LTE will have poor speed and randomly not work even though the status bar shows a signal in spots with good Verizon coverage. I also noticed that my bluetooth will randomly disconnect from devices and is very glitchy. Also the battery life has been not great. Only about 5 hours SOT with lot of apps disabled and all settings adjusted for maximum battery life.
Also I noticed that if you go into settings/connections/mobile networks and observe the signal strength it is always either -120dbm 99asu or "not available" which is not good.
I Noticed the LTE issues after an update(not sure which one it was)
I tried Updating to the latest ASD9 and there is no improvement.
I did all the basic troubleshooting through verizon(new sim, provisioned the device again). No improvement
I reset the phone with no improvement, I flashed the factory firmware ASD7 with odin.... no improvement.
Finally I brought the phone to a local Samsung experience store.
They tried to run some tests but it would not complete them. They were well aware of the problems with sprint phones but were surprised to see these issues on a Verizon phone. Eventually they agreed to replace the motherboard but had an issue flashing the serial number to the new firmware so now finally im going to get a new phone. Fingers crossed, this has been such a headach
