On Thursday, my Xiaomi Mi A1 arrived. Upon activating the sim (MetroPCS), I was faced with mobile network issues. I had problems such as dropped connections, delay in calls and interruptions during calls. I factory reset my phone about 2-3 times in attempts to fix it but it remained the same. I also cleared default apps and tried to troubleshoot it but had no luck.
Every time I make a call, it takes about 10 seconds to go through and sometimes it just drops it. Most of the time, the calls are choppy and it is hard to communicate with others. I also noticed that some people are unable to call me and it goes straight to voicemail. I have an average of 1-2 network bars. Very rarely, such as last night, I had 3-4 bars and my calls worked correctly. But that didn't last long and now I'm back to the same problems.
If you have time, you can try to flash Nougat rom if the problem still persists. Try to take the phone to your operator's store, they can do something about it.

I'm thinking of returning it. What can the operators store do about a weak signal? Its a problem with the phone I guess. MetroPCS uses Band 4 for LTE and I have a really weak connection for some reason.

Dial *#*#4636#*#* and select lte/cdma/umts (auto prl) that should solve your problem. Most Xiaomi phones come with Chinese network settings as default.

I dont know, for example my SIM card was working but had no signal, so I went to their store and they changed SIM card to newer one and everything was working fine. Sometimes SIM card can get corrupted or damaged.

I got my G2 a couple days ago and I must say this phone is amazing..coming from a g1 I had for 2 years its quite an improvement. The only minor problem I'm experiencing is with the radio signal..most notably in my house..on my G1 I always had signal and internet connection. Now with the G2 I constantly loose connection all through out the house and the only way to get it back is to switch the airplane mode on and off and it picks it up right away, only to go away a few minutes later..I don't seem to have the problem anywhere else.
Was wondering if any of you guys can shed some light on if there is a way for me to figure out why the signal is so random in my house and it was ok with the G1. And why airplane mode seem to fix it for a short while.

did u activate the sim card that came with the phone or still using the old one?
I'm still using the "old" one still but considering I got it 2 months ago I wouldn't think its a big deal unless the sim that comes with the G2 is any different?

I asked because i was told to activate the new sim card to avoid issues likes the ones u seem to be having.
I was told to replace the sim card as well. After doing so there was no change in the reception of the unit. The downside is that the sim card does fine in my Vibrant but does not work at all in My Nexus One. Tried two different new sim cards and each time the Nexus One refuses tacknowledge it while the G2 and Vibrant do. I have found no difference in signal quality or strength with the new sim. The new sim card has a much smaller gold contact area and that area is a slightly different shape,
I went ahead and activated my new sim card to see if maybe it'll fix the problem..ill let you guys know how it goes
Sent from my T-Mobile G2 using XDA App
Changing the simcards will not work. If I put my simcard in my iPhone 3G or my G1, I'll have 2 or 3 bard with 3G, but with the G2, It switches up all the time, from Edge to 3G or no data at all, with 1 or 2 bars. I also have five other family members that also have T-Mobile phones and their getting about 4-5 bars on their phones. So it's not the sim or a tower issue.
There's cleary a problem with these phones.
This mourning I woke up and found the phone with no service, no bars. I reset it and came back, this afternoon I left the phone on my bed, came back to it, and again no service, it seems the service keeps going out for no reason.
Another is, I live in a big building, when walking in and out the building, my data connection will drop, or sometimes I won't even have any service, and again the only remedy is to restart the phone to get service back, airplane mode won't even fix it.
Yea the new sim hasn't really fixed anything at all..

damn i was about to try that... guess i'll keep waiting... maybe an OTA radio update will help this cause it's really getting annoying.
I don't have a problem with my G2 dropping signal completely, but I have noticed that my 3G is very spotty. It's probably because I was spoiled the the MyTouch Slide's 3G only option.
Yes, I've noticed that the signal isn't quite as good as my G1. It's seems to be about on par, if not slightly below my friend's Vibrant.
But remember, the G1's radio really sucked once upon a time. Radio updates. They will come. Every phone that has OTA updates always gets new radio, in my experience.
I'm on my 3rd G2, mostly for manipulating the purchase price, and have noticed on this 3rd one that the spring is looser than the first two, the phone resets itself and often, and I'll loose data even though it shows I'm connected. This will happen in edge or hspda. I'm taking the phone back tomorrow.
Crappy thing I just put the ZAGG complete invisi shield on it. WIll Zagg comp me another cover you think?
If only Tmobile would activate the UMA calling over wifi. This would be the perfect phone with perfect service.
I am going to call tmobile in the morning and see if I can get any word on the UMA release. If not, the phone may have to go back.
I'm having the same problem, not at my house but at a local ihop that happens to be walking distance from where I'm moving in a week. I tried a reboot, airplane mode, even pulled the sim card and nothing worked. I got signal back once I left, but since it's right by the new place I would like to not have to deal with this.

well ive been searching around and i think ive found something that could help..
if you dial *#*#4636#*#* you will get a little screen of information about your phone, go to phone information, under phone information scroll down until you see select network type, the network should be automatically set to "WCDMA preferred" ive been playing around and i set mine to GSM/CDMA auto (PRL) and since then (about an hour roughly now) i havent lost my signal or connection in the same spot i was loosing it in my house every 10 minutes or so. not sure if this fixed anything but so far so good. definately will let you guys know if it continues to be good or if it doesnt stay consistent.
heres some information also in case you dont know which one would be best for you.
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (Maybe the Samsung Galaxy S will take advantage of this???)
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this

Having same issue with the signal. Swapped for a new sim but still the same. Sometimes service drops completely and I have to go through the settings menu to search for a signal in order to get some reception
Sent from my T-Mobile G2 using XDA App
phone came in wcdma preferred stock... I came by that option too but I would much rather suffer with spotty signal [HSPA] over Slow edge speeds...
that said I may turn on GSM only when I'm indoors with little coverage, should save a lot of battery.
is there a setting that forces the G2 to go for the G3 or H setting instead of the edge? I live in an area where my phone can get both and it always goes for the edge signal instead of a weak H signal and the edge is soooo slowww.

*#*#4636#*#* then phone information, then scroll down and change the drop down from auto to wcdma only. Only problem with that is if u go to an area with no 3g, u get no service and have to change it back or go under the settings and wireless to enable 2g connections

Hi All,
I have been facing major call dropping issues on my new Samsung Galaxy S4 which i previously thought to be a problem with my new postpaid connection. but later on searching realized this to be a bug which many others are facing world wide. I couldn't find any proper solution to it other than this.
What is did is change in settings>connections>more networks>mobile network>network mode> then select gsm only. Have been using it for 2 days now and seems the issue is resolved.
Might help others.
This isn't a fix, why would I run my phone only in 2G / Edge mode... for a 3G/4G device???
There is something strange going on here, I've replicated this issue on 3 different carriers in 3 different countries (AT&T = USA, Chunghwa = Taiwan, China Unicom = China), so it's NOT a network issue. I strongly suspect that the first batch of Samsung GT-i9500's have faulty network chips, there is no other explanation as to why this is a continued issue even after all these software updates.
I had a reception problem with the I9505 too, so it's seems the hardware isn't the problem. With the newest firmware, the problem is gone.
My reception is great, only in shelters it goes down to zero bars and still didn't had any call drops.
I use an I9500 which I bought it on 13/05.

This isn't a RECEPTION issue. Randomly, throughout the day:
1) Signal will go from full bars to NIL... I'm talking airplane mode with the circle with a line through it.
2) Some time later (a few seconds to longer sometimes), the signal will come back along with 3G / H+.
It has improved with software updates, but it still happens and is completely random both time and location wise. The worse part is, this will happen sometimes in the middle of a phone call, which means you suddenly get disconnected. And yes, this happens when I'm sitting in one spot with a strong signal, so something is seriously wrong with some of these early i9500's.

Happened to me with a self cutted microsim. Replaced it with a microsim factory made solved my problem.
I was experiencing the same issues with my i9500. It all solved when I flashed MG9 modem. Since then, I´ve never lost signal or service.

It was all good with MDM.. Then I flashed the German rom and updated to MGA and then MH2. Both of them(MGA and MH2) find it hard to stick to the 3G signal and it just drains the battery. I put it to GSM only (2G) and the signal is full but the battery in my opinion is still not AS good as MDM. I sooo soooooo hope they fix it in the next update and soon!

I've had the same issue on 4 carriers: ATT, China Unicom, China Mobile (2G only), Hong Kong (forgot the carrier). This only happens on my I9500 because I cannot replicate it on my HTC One. In all instances where my I9500 craps out on me my HTC produces a strong reliable signal that never drops.
Same thing here... it happens on China Unicom, Chunghua (Taiwan), and AT&T. There is something seriously wrong with a HUGE lot of i9500's.
I have the i9505 and I only have 3 options in the network mode setting menu not 4 like I was told by other users there should be.
My network data connection drops out more often than its connected reguardless of the signal strenghth bars or also despite the about phone signal information.
I have tried a few roms all with the same problem. Im on the 3 network uk I had galaxy note before the s4 and never experienced any problems at all
It is also not area related as I have checked the coverage for the area and im in a fantastic area for cover but if I am indoors outdoors at home my dads or the shops still the same constant no internet connection error the h or h+ or 3g icon just vanishes from the too for no reason.
Can anybody at all offer any help or advice in any way in reguards to it or is it most likely I have a bad handset?
If I have the network set to auto or wcdma it is the same problem .... if I select gsm only I dont get any data internet connection at all is this right?
There is no wifi on either to cause any interferance I keep it turned off on the handset and bluetooth is off too
Thanks for any help or advice

Hmm, really bizarre that both 9500 and 9505 handsets are seeing the same phenomena. Could it be something software related then?
Question: For those that see this cutting out and returning of network signal, do you have a bunch of stuff disabled / uninstalled / removed?
Hi,
did anyone using Umi Super have any problems with using 4G at 800MHz? Im on giffgaff and even though Umi Super is supposed to work at 4G under 800MHz (thats what the specification states) i cant manage to make it work. I have perfect 4G coverage, 4G sim, 4G tariff, even gave my sim to a friend with S7 edge and it worked on his phone. Maybe new update will fix that? I tried with different sim from different operator (LYCA) and it works but 4G in LYCA is at 2100MHz so I didnt really check the 800. I tried everything and still nothing. Did anyone have similar problem?
I actually bought 2 phones of the same model so I decided to check if 4G worked on the other one and as I put the sim card in I just remembered something and realized same thing happened with my phone. When I put the SIM card in for the first time it DID automatically go to 4G, ok, when I looked for available networks it found O2 4G, granted BUT!!! when i got to "preferred network type" there is only 3G to pick, and THE MOMENT I PICK IT there is not possible to go back. Every network I find from that moment is only 2G or 3G. Now i reckon that a software problem right? See attachments
It is a software bug and I think I sort it out after flashing the phone. For now I sorted out the problem using Networks app by Philipp Mangalov and switching network to LTE/GSM auto
Well it seems the data part of the UMI SUPER is not so super, is it? I face a similar problem but worse. The 4G band of 800 doesn't work(despite being advertized by UMI as supported) but luckily the band of 2100 works without any issues. The problem comes when I'm out of 2100 band coverage and phone must switch to 3G - then I lose all data connectivity completely. So basically whenever I'm out of 4G 2100 coverage(which is often) I am without any connectivity! Anyone facing the same? Solution?

I don't have this issue at all. My UMi Super connects perfectly to my 4g network under 800MHz without an issue here in Uganda. You can install the MTK Engineering app from the play store and check the band compatibility on ur device and you can also set the mode using the same app under android settings.
You could also try updating to the latest OTA which is 20160810 or the one before it by downloading the files from forum post here and saving them to ur phone and updating manually if you don't have the current OTA

You need Giff Gaff settings in access point name. If you try and use O2 4g it doesn't work even though Giff Gaff uses O2 network. Settings are really easy to input but MUST be Giff Gaff not O2.

All that's needed is GiffGaff settings inputing manually. Very easy to do. O2 settings that the phone recognises when a GiffGaff sim is used WILL NOT WORK. The Network is O2 but the APN settings for GiffGaff are totally different.
All you guys that think you know what you're doing obviously don't.
No need to Root or use GravityBox or any other App.

Well said. I just shake my head in despair when I see how totally clueless people try to be teachers and Internet gurus with very limited knowledge about the task at hand. These comments should come with warning stickers.
For those who want to be able to switch between 3G/4G and LTE only, use this nifty little APK that I've attached below. It will allow you to enter engineer mode without using the dial code.
Hi
This is a bug implemented in Android 7.0.
I had the same.
1 Just force in your parameters 2G/3G networks
2 wait for network authentification (no more excalamtion mark)
3 go back to 4G
Every thing will be OK to next switch off or plane mode.

LTE band 7 (2600) not working
I recently received my new Umi Super and updated to the last firmware V7.01_20170413, everything works fine except for the 4G. I live in an area where band 7 (2600) is available but the phone can't connect to it. Of course, my preferred network type is set to 4G/3G/2G (auto).
I read a lot about the issue on the internet but I can't find a solution.
I checked the BandMode on the phone by dialing *#*#3646633#*#*, band 7 is included and checked. However, when I tried to remove the other LTE bands and keep only band 7, I got a message explaining that the list can't be empty ("Failed. The band is changed from not null to null, it is illegal"), though the list was not completely empty because band 7 was still selected.
Also, I tried to change the radio band by dialing *#*#4636#*#*, but process com.android.phone stopped working when I pressed "select radio band", even after I cleared cache in phone and sim apps.
Can anyone tell me how to fix the problem and get connected to 4G.
BTW, Network by Philipp Mangelow is not available anymore. Switching between 3G/2G and 4G/3G/2G settings doesn't fix the issue. I tried the giffgaff settings, but the APN gets deleted as soon as I try to save it.
Thanks

I recently received my new Umi Super and updated to the last firmware V7.01_20170413, everything works fine except for the 4G. I live in an area where band 7 (2600) is available but the phone can't connect to it. Of course, my preferred network type is set to 4G/3G/2G (auto).
I read a lot about the issue on the internet but I can't find a solution.
I checked the BandMode on the phone by dialing *#*#3646633#*#*, band 7 is included and checked. However, when I tried to remove the other LTE bands and keep only band 7, I got a message explaining that the list can't be empty ("Failed. The band is changed from not null to null, it is illegal"), though the list was not completely empty because band 7 was still selected.
Also, I tried to change the radio band by dialing *#*#4636#*#*, but process com.android.phone stopped working when I pressed "select radio band", even after I cleared cache in phone and sim apps.
Can anyone tell me how to fix the problem and get connected to 4G.
BTW, Network by Philipp Mangelow is not available anymore. Switching between 3G/2G and 4G/3G/2G settings doesn't fix the issue. I tried the giffgaff settings, but the APN gets deleted as soon as I try to save it.
Thanks

You may try to force 3G and then try to force 4G
You may try to user another IMEI number from a UMI device with 2600 support (of course backup/write down the original one before just in case)

After the update to Nougat 7.x how long does it take to do a full recharge?
Do you still have fast charge feature (< 1 hour) or do you lost it like all users reported so far?
What about your GPS? Do you have a fast fix after cleaning history and is it reliable (not losing signal often?).

Is it safe to change the IMEI number? and where can I find another number for a UMI device?
GPS is working fine, it fixes pretty fast, but I'm not sure about interruption in the signal because I haven't used it enough yet
On Sprint's Network, unlocked bootloader & critical partitions. Anytime I even receive a notification for a phone call coming in, my LTE is dropped instantly. Deny or hang up the call, it comes back. I've read that Sprint's 3G can't handle voice and data at the same time, but this is 4G. Wifi is also completely useless on this phone as it stays connected for about 60 seconds tops.
Tried doing a complete wipe and reset to both Pie stable and Q beta 6, same exact thing. Tried all the network options in settings and nothing.
Does anyone with Sprint have working LTE during a phone call? I'm trying to figure out if it's a **** copy I got from Amazon, or the network. Thanks.

I have the issue. I also can't get LTE+ to work either. I'm on Boost, but they use Sprint. All stock roms and I can't get 4G at all on custom roms. I bought mine directly from Essential.

I can't say anything about Sprint, but VoLte on Verizon behaves the same way for me on Q beta 6. If the radio cycles for any reason I lose VoLte even if it shows selected. I have to toggle it in network settings for it to work.
Just curious, if you go into the phone info with *#*#4636#*#*, does it show that VoLte is provisioned?

It's grayed out for me. I can't enable it. Maybe calling Boost customer service might result in fixing it.

Problem background: I was having problems when phone was getting stuck at WCDMA (found out using network cell info app), losing sms and calls function, and not switching to other network types, requiring a restart or a toggle of the 2nd sim to off and on (I had my sim 2 off most of the time).
Solution: enter *#*#4636#*#* in the phone dialer, phone information, set preferred network type, NR/LTE/TDSCDMA/GSM.
Phone will not connect to WCDMA but for me, this is the better option since LTE signals are stronger in my area.
One benefit was also an improvement to my battery life, I guess because phone will not search for the weaker WCDMA signal anymore.
I hope you find this useful and you also resolve your problem.

Sounds to be connectivity. They should have gave you a new sim, unplug modem, repulug modem. Clear cache, reset phone, this looks for best tower signal. Make sure your on the latest update. These are basic troubleshooting. If nothing call one plus technical support number. They will ask if you've done these steps. They talk you through More steps. Get it fixed!! Do not Hard reset unless instructed to. Get back.

Pretty sure this is not a sim or network problem. used the same sim on an iphone and samsung and never had this issue.
I had signal issues a found turning off smart 5g in settings yielded better LTE and 5g connection there is a reddit post about it even maybe try it if you haven't already worked for me and my device is 8t global on T-Mobile by the way.
