Weird signal problems GSM HTC One m7 on Simple Mobile (T-Mobile) - General Questions and Answers

This http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemVersion&item=121805828785&view=all&tid=1659658376002 is the M7 I bought. My older phone is also an M7 but GP edition, has no problems with the same SIM and I get consistent H data signal. Now on that new phone, when i first got it, it would not hold signal at all. One moment I would have 4G with full bars, the next not only does the data drops but entire signal goes out and the phone becomes useless.
I went through android ROMs, Cyanogen mod, Viper, couple others. Always made sure I had the right version of ROM and firmware. This problem still persisted.
Now, after doing FULL wipe, system and everything. I once again installed Viper rom, latest version for m7 which is 5.0.2 I think. I also installed latest firmware that was released for 5.0.2 and now something else broke. No matter what settings or APN (tmobile OR simple mobile) I use I ONLY get Edge data signal. Not only that, but it shows that my signal is full, yet for some reason I can't make and probably cant receive calls either, 1-2 seconds go by I hear a beep and the call drops without ever reaching the normal consistent beeeeep beeeeeep when you wait for the person to pick up, but texting still works.
I contacted the seller and he assured me that the phone is brand new and asked me if I could take it to a repair shop and he would pay for the costs, I thought it was a bad idea for multiple obvious reasons. 2nd contact with the seller, he asked me if they could refund $20 and I could keep it, I said no. Last contact, he says that he could refund me $50 and I could keep it, but if I disagree he gave me return address, I guess he expects me to pay shipping.
I guess they would have to resell the phone as used if I return it, that's why they want to go as far as giving me $50 to keep it, that way I guess they still in profit. But that just makes me doubt even more, is the phone really not defective and I ****ed something up with flashing ROMs/Radios/Software? But how could I if I matched my roms and firmware with my phone's model (stuff like m7_ul and the 111111111 id). Seller listed this phone as GSM with bands that T-Mobile supports, so why do I have so many issues with it? Should I not waste anymore HOURS looking around forums and flashing **** and just send it back and get it over with?

Galaxy Nexus LTE Won't Hold LTE Signal

I'm posting here on behalf of a friend because I've tried everything I think I can do to help, but to no avail. I'll try to make this quick.
My friend bought a Galaxy Nexus LTE in December and it worked great for a few weeks, until the vibrator in the phone broke - he took it to a VZW store and they replaced it for him.
Upon receiving the replacement phone, he was having trouble with LTE staying connected. It would continuously drop and instead of falling back to 3G, it says he has no signal - signal indicator in settings displays a red bar (i.e. no coverage).
He took it back to VZW and they tried his SIM card in an employees phone - same issue happened to that phone. They then tried his SIM in a new phone off the shelf, same thing happened again.
Verizon is saying it's an issue with something at the account level, but I've encouraged him to go in and complain until they give him another replacement, just in case. However, it's very odd that his SIM card in three different GNex devices produces the same issue, even though his first one worked great. They have said that a future software update would fix this.
The other day I installed the leaked 4.0.4 update on his phone to see if the new radios would work, but the same issue kept happening. So I reverted him back to 4.0.2 so he could take his phone back to Verizon and beg for another replacement. Unfortunately I forgot to re-lock his phone so I still have to do that before he takes it in.
Has anyone ever heard of this before? It seems so odd that his SIM card would do this, but I still think that Verizon owes him another replacement device since he has a phone that isn't working like it should. He's getting a big discount on his family plan but he'd prefer to have LTE on his new phone.
I would love your thoughts - this just doesn't make sense to us. Any suggestions other than replacing the phone again? It sounds like VZW doesn't want to do that for him so it might be easier to fix it another way.
Can't speak for Verizon itself, but I have been through several SIM cards now on Telstra. Same issue, all of a sudden they are unable to pick up signal at all. Seems the pre-paid cards are more susceptible.
I'd ask for a replacement SIM, as opposed to a replacement phone as it's been proved the issue exists on multiple handsets already. If a new SIM doesn't alleviate the issue, the VZW rep may be right in that it is at the account level.
Good luck!

Advice needed re: which Xoom to get

I currently have a 4G Verizon xyboard that is going back to Motorola for the 2nd time in 2 weeks. Bought it the end of March. You guessed it - I'm not happy with the quality since this will be the second repair and it's not like I've thrown it around. On the other hand, I love the 8.2 size and when it works, it's a nice tablet. But that's the hitch "when it works", which is not a lot these days.
It started with charging and lockup issues which were repaired, and now it won't stay connected either to wifi or VZW on a consistent basis (as in, sit in one place, get connected with good signal, don't move, wait 2 minutes, lose signal). And since I bought it because of the VZW coverage, I'm paying for a data plan I can't even use.
So, I'm getting prepared here - if by some chance, mine fails a third time, I'm changing xooms. Given the love that the original Xoom still has on here and from Google, I'm going to try and get a model that will upgrade, which probably means ebay or craigslist even though mine should still be covered under warranty.
Which xoom do I want - I see version numbers all over the place and I'm confused. For example, I think there was a thread about the 'original' 3G xoom being upgraded to 4G through Motorola? So which model is/was that? If you have one of those models, does the 3G/4G service work well for you? Is there a different model I should look for?
Thanks in advance - any useful advice would be appreciated!

[Q] Unlocked Telus One S Constantly Disconnects on MTS network

I bought my One S from Telus through a friend who's a Telus customer this past June and used an unlock code bought online to use it with my carrier (MTS). After setting it up with the MTS APN settings it worked perfectly for several months. Then around 2 or so months ago, I got an OTA update to 4.0.3 and as soon as I got the update, the phone started regularly dropping the connection to the network. Signal strength wasn't an issue, it would just cut out completely, giving the message about emergency service only. Some days it wouldn't be too bad and would just cut out momentarily and sometimes it would drop for a good time or drop so repeatedly as to make the phone unable to even dial out. It would sometimes even vary in severity throughout the day. I haven't rooted or unlocked the phone in any way except for a carrier unlock code.
As I was very busy with school, I gritted my teeth and beared it but it seemed to get progressively worse to the point where I finally sat down to seriously look into, and got on the phone with MTS tech support, HTC tech support, as well as trying to talk to MTS sales reps at their store locations. MTS is clueless on what to do (or just refuses to help) because they don't sell the One S. I talked to HTC three times and their only solution was to see what happens with sim cards from different phones and they also noted that the stock software, as well as updates, are tied to the carrier and could be causing problems.
MTS also talked me into buying a new sim card and seeing if that fixes the issue, where it actually made things worse somehow and now the phone often cannot get a connection at all or drops it and doesnt pick it back up (on the settings screen, "mobile data" gets stuck at "turning on" but even voice doesn't work). I've tried getting other people's sims to try in my phone but they all seem to have ones of different sizes. All I've been able to try is a Rogers sim (which I only could test for a short time, but seemed to stay connected and stable for that time) and a Telus sim (which wouldn't work at all, strangely enough. Though one person I talked to at HTC said that by unlocking my phone its possible I received the OTA update from a different carrier such as Rogers).
I'm not sure what to do here as I've tried messing with many settings and searching for solutions without finding one that works. One of the HTC reps I talked to said that I could either send it in (and lose the phone for 2-3 weeks without a guarantee this wouldn't happen again) or while they can't recommend it, I could try rooting the phone and downgrading the software to what it was before. A guy I talked to at a local cell repair shop listened to my problem for about a minute and a half and then said rooting would fix it.
If anyone has any suggestions, I would greatly appreciate hearing them. I'd like to get some more input before I void the warranty by trying to root it and replace the software with some in case that doesn't fix it and I have to send it into HTC for a big fee.

No 4G - call drop outs - Poor battery

Hey all,
A mate of mine has a S6. Since new, he has had constant issues. He never has 4G, (on Telstra in Australia), and when he makes phone calls, as soon as the person answers, it cuts out. At the most, a phone call will last 1minute.
We have ruled out the SIM as being an issue and all the APN's are correct.
Telstra want to send the phone off to Samsung, which will result in nothing being done and they are saying there is a six week turn around!
What are the chances it is software related, rather than hardware?
If the general consensus is that it is software, I might flash a new ROM onto it for him.
If hardware, I suppose he has no option but to hand it in and play the Samsung game of, 'No fault found,' or, 'it is water damaged'.
We were on Glenferrie Rd today, (Malvern, Melbourne), and I had full 4G while he had no reception at all. Nothing. Not even 1bar.
Due to the poor reception, his battery life is pathetic. With barely any usage, he'll get 6 hours out of it. Android system seems to be the main culprit when you look at the battery usage.
He has already done a factory reset.
Is this a common issue and would it be worth flashing a new ROM?
It sounds like a hardware issue. You shouldn't need to mess about with it to use its fundamental features. Your phone carrier should have records of your complaints, use that as a case to get them to replace your mates s6. The bottom line is that if they sold you a defected device they need to replace rather than send it off for repairs. It's a bummer but I'll go down this route if I were your mate; consumer's rights etc..

Sounds like the network to me which would also explain why the battery is working harder
I would go into a telstra shop (big one in city seems to be good) and ask them to replace it...

Verizon LG G5 (VS987) dropping data connection

Hey guys,
I recently got an LG G5 last month. The phone was running pretty darn well until about a week and a half ago. Before I go into detail about my problem, I would like to point out that this is the 3rd 4G phone I've ever had through Verizon, but this is the FIRST time I've encountered this issue.
Anyway, on to the issue. My data signal is dropping TREMENDOUSLY. In areas where I used to have a moderately weak 4G signal I'm now dropping all the way to 1X or no signal whatsoever. The troubleshooting I've performed consists of the following:
1) Rebooting the phone
2) Toggling mobile data off and back on
3) Toggling airplane mode on and back off
4) Experimenting with different network types (Global and CDMA/LTE)
5) Booting into safe mode to see if any 3rd party apps are causing the problem
6) Taking the SIM card out and putting it back in
7) Replacing the SIM card altogether
The only one of these techniques that showed promise was replacing the SIM card. The phone seemed to work well for a few hours, but later in the evening it went back to it's old problems.
I've searched online for this issue, and I've seen several other cases of this with no real solution. Here is a list of links to other people's complaints:
(The first 2 links are for the Verizon variant, the last 2 links are regarding G5's from other carriers)

https://support.t-mobile.com/thread/131390?start=0&tstart=0
Anyway, Verizon tech support is pretty much useless. When standard troubleshooting doesn't work, they typically have two final "troubleshooting" techniques: 1) Factory data reset 2) Warranty replacement
I refuse to do a factory data reset because out of all the phones I've ever owned, a factory data reset has never served as a permanent solution, EVER. Occasionally, it might fix the problem for a short period of time, but it inevitably goes back to it's old problems. Not to mention, it's such a pain to get my phone set back up the way I like it after the reset.
The warranty replacement seems like a waste of time too because of other people having the same issue. It sounds more like a problem with phone design rather than my specific device.
Anyway, do you guys have any troubleshooting suggestions? Have any of you experienced the same thing? If you have experienced it, PLEASE call Verizon tech support at least once a day and report the issue. It's currently not categorized as a "known issue" because it's not received enough "hits". However, once enough people report the same issue enough times, Verizon deems it as a "known issue", and they get off their butts to find a solution to the problem. We need a ton of people to complain about this.
I have what sounds like a connected issue.
Mine started off by going into global mode then would loose data connectivity. So figuring there was something wrong with the phone but also figuring there was an easy walk around (even though it was a pain in the butt that shouldn't happen) I made a shortcut to take me straight into System Select so I could change it back to CDMA/LTE. This worked for a while. Then the phone started doing the same thing; no network connectivity at all, even while being on CDMA/LTE. So what I ended up having to do there was go to into System Select change to Global wait for a couple of seconds then change it back to CDMA/LTE. This would fix it for a couple of days. I think at that point the phone decided it was being too easy on me because next, it started doing this to me every day. Frustration level went way up! But, the phone wasn't quite finished with me yet. Now that it was doing it once a day it started loosing signal bad enough that it started to miss SMS and Phone calls as well. This was pretty much the last straw. I waded through Verizon's level 1 tech support and was then forwarded to level 2. Surprisingly enough, level 1 did more than level 2. At the end of level 2, I was referred to LG's tech support. LG's guys were a joke. They had me do a Factory Restore, that was it. He had me do that and said if it didn't work go back to Verizon. So back to Verizon I went. They sent me a new (read factory refurbished phone) to replace my phone that I had purchased brand new. The "new" phone worked great for a few days then it started doing the switching to global thing again. So far it's stayed there for about a month now.
Long story short on my experience: Everywhere I went they said, "I've searched all over the net and I can't see anybody else having this issue." You need to contact Verizon and wade through their inept tech support. If you don't they'll never know the phone has an issue. I tried a bunch of stuff myself, including switching the SIM card. The only thing I haven't done is drop a new battery into the phone, which I'm still considering doing. But if they think it's just me they aren't going to care. They need to know there are more than one of their customers with this issue!
