Hi, I have D801,
I recently started to have this wierd problem, where I would lose all my signals completely, and comes back on, just without an LTE (regular 4G).
after this, if i go in to network settings, it is defaulted to WCDMA only or WCDMA preferred, instead of the ones with LTE in it.
no matter how many times I change this, it keeps going back.
I literally live right next to the tower.
I did not have this problem a day ago, I don't know what is causing this problem
i have flashed

this on my D801, and this is the only thing I did before having any issues.
or maybe it's something else.
APN setting looks normal etc.
can anyone tell me what to do ?
I tried going back to completely stock, and the problem is still there.
I used this method.

is there anything in this procedure that doesn't get restored to stock?
HELP!
I was at a location where the network reception was bad and I lost signal. My phone has not been having network signal since then. Signal strength 0.
I am having a problem on my phone where I am frequently losing LTE - my phone goes to 4G and I have trouble with data.
If I turn Mobile Data off and back on it connects to LTE again.
This seems like it started happening after I updated to the GoldenEye ROM - before that I feel like my LTE coverage was a lot better and more consistent.
Can anyone advise me on how to diagnose and hopefully fix this issue?
Hi All,
First time poster with an unusual problem. I live in Australia and have a Samsung Galaxy S5 SM-G900F which is the European model. Up and till recently I was getting Telstra 4G reception. Now all of a sudden I'm only getting constant 3G reception. I have confirmed that there are no 4G network repair/maintenance/upgrade issues in my area. It was only in the last week that I noticed the constant 3G reception so I can't really pinpoint a specific incident or exact date as to when it actually started happening. Here is what I have tried thus far:
Phone restarts, changing network settings and switching to flight mode.
I've confirmed that the phone network is set to LTE/WCDMA/GSM (auto connect).
I have done numerous hard resets, cache wipes, Dalvik cache wipes, drive wipes, etc.
I have rooted and unrooted the phone numerous times.
I have tried several different stock and custom ROMS.
I have tried 4G SIM cards from other phones.
Tried numerous network switching apps.
NOTHING WORKS!
I always love to tinker with my phone so I'm always looking for ways to improve the phone's performance. It may be that an app (battery improvement/tweaking type apps) I installed somehow changed the network settings but I would have thought a million hard resets would have sorted that all out but apparently not. At the moment I'm running a rooted stock Android 5.1 ROM. I've tried stock Android 4 and 6 as well with no joy.
Here is the unusual thing. When I put in another 4G SIM card into my phone the network still remains on 3G but as soon as I put my SIM card back in 4G magically reappears. It's bizarre. At least I know my phone can still get 4G. You would think that would solve the problem but it doesn't. When I am in an area where the 4G signal is weak the stronger 3G signal kicks in as it is supposed to. When I get back into an area with strong 4G reception the phone remains stuck on 3G and no matter what I do it won't go back to 4G unless I go through the convoluted process described above.
I am all out of ideas. I think I have tried everything possible. I've trawled the web and I appear to be the only person in the world with this problem. I don't know if it is a software or hardware problem with my phone. My SIM card works in other 4G phones so I don't think it is part of the problem. At the end of the day it's not a big deal as 3G is fine but I'm just one of these people that has to fix a problem. Worst case scenario I'll probably upgrade the phone in the next 6 months.
Any suggestions or tips other than what I have listed above would be greatly appreciated. Thanks in advance.

Okay, so I really like my Moto X Pure. I used it in Florida with no problem with network or data or text or anything. The instant I left Florida my data dropped (couldn't load anything anywhere), I would get 1 text every 5 minutes, and phone calls couldn't be completed.
If I run speed test it'll take about a minute to find a server, my ping will be 500+, and my speed might get up to 0.9MBps for a split second, then drop to zero for a few seconds, then a spike of 0.9 again, etc.
I can watch the network bars go from full, to nothing, to full, to nothing, to 1 bar, switching from LTE, to H+, to 3G, to 2G, and all back over again. On every ROM, with every carrier, rooted, unrooted, stock, modified, updated radio, OTA radio, everything.
I've tried EVERYTHING
Revert back to completely stock (was running CM13.1)
Tried other ROMs
updated radio/modem
downgraded to 5.1
SWITCHED CARRIERS from Verizon to AT&T, tried T-Mobile sims....
EVERYTHING gives me the same issue! If I plop the sim cars into my nexus 6 or my G3 then I get connectivity and speeds no problem.
Unfortunately since I have unlocked the bootloader, I don't believe I can get warranty on this phone.....
But why would it work PERFECT in Florida, but nowhere else in the entire United States? I mean, NOWHERE. I did an across the country road trip.
Yep same here

Huhuhu I guess it's time to sell.
I got the G5 and didn't care for it. I think I'm actually just going to get a G4.
I'm in the same boat. It seems my LTE speeds are fairly good here in Canada on Rogers. Sometimes I get decent 3G speeds but mostly it just fails entirely. Completely stock. No problems with SIM on other devices. Phone is 2 months old but it's been doing this since the beginning.
After the recent update, my signal has gone straight to hell on Sprint. Other places I used to be fine can't even connect to 3G. Ideas?
