mi band 4 constantly freeze and unresponsive screen - Xiaomi Mi Band 4 Questions & Answers

Hey. Got my first me band 4 some time ago. At the begging it was ok, it was working as expected and then it started to crash. Notifications wasnt appearing, it wasnt counting steps etc. Unpairing and pairing again solved issue till one day when band crashed again and bands screen got stuck at "Pair First" image. Does not response to pair anymore. I mean, phone are able to find band but when i have to confirm pairing nothing appears on bands screen. Any solutions? There is no warranty so there is no option to bring it back or refund.

Is your band the NFC version or the non-NFC version?
Which firmware version is your device running?
Did you ever delete the received notifications from the device?

[Q] Answer inconvenience phone use, No power display

Very good day
I have a query, I have a HTC Touch PRO 2 RHOD300
The phone is counting on the next problem happens when you try to turn the screen by pressing the button on top that will not start and if you take the pen side of the phone just turn on the lights in the lower keys where this call, Windows key, Back and Finish. The phone returns to regain normal when a call comes in after the returns to be shut down and locked and not back on the screen.
In other cases there is the disadvantage that remains off, open the phone to expand and to use the qwerty keyboard and this light comes on but no screen and if you call the phone number that shows no signs of life with this call More on the other side of where you are calling is heard that he was calling.
My question is whether they have a patch for the solution and if someone else had already reported this fault, this problem is being presented to several phone numbers of friends and wanted to see whether if they had a patch to fix what they could afford to apply it to the phones have this fault.
If in case anyone has a solution for this above I would appreciate very much.
Funny... I have been experiencing this same problem just recently. I have another identical phone and replace the sim card in it with the same results. It doesnt appear to happen to the phone when the sim card is not installed. I have tried hard reset, selectively installing programs, thinking it was a programing problem with one or another, but nothing I tried seems to change the problem. Any help is appreciated.
Thanks.

Note that for my part I've been trying to give solution to the problem and have identified the following place your sim but the connections do not let my ISP leaves your network connection as my job to your phone so you do not use the 3G data network, thus the problem will not happen.
To me this is what happens, the phone went dead, but if you remove the stylus from the side, the lower lights are lit but not the screen, but if you make a phone call to your cell this and respond, but entering Idle this again locked again.
HTC have written to me but these have not been resolved.
I am in Guatemala and I used 2 different companies and the problem persists.
You friend in that country is, and have only confirmed this problem also began to give you on Friday May 20? because that was the time when many telephones HTC Touch Pro2 here began to have these symptoms.
Yes. Friday would be correct.
So if the issue is global, it is the end of the world of mobile
This doesn't appear to be a new problem though. If you search on "Screen of Death", it is quite common. However, I have tried several of the solutions that I have come across, with no go. It is complicated by the fact that we started experiencing the problem at the same time.

Radio randomly goes off

Hi,
Wondering if anyone is experiencing this issue.
Got the uk version of galaxy nexus, GT-I9250 ordered from an online store from the us. Only within the first 24 hours I experienced a time where I suddenly lost my 3g.. the signal bar shows no service. Only way to get back is to reboot phone.
After it happened few times and doing some testing, it turns out the radio just shuts down. Going to settings, about then status shows radio off. Going to the secret menu that gets accessed by typing a nmber also says radio is off. There is a button to turn radio on.. but it does nothing.
Tried factory reset, .didn't install any apps. Still issue occurred. Also noticed at random time before the total radio sshutdown, I do lose 3g few a minute then comes back.
See my screen captures showing issue attached.
The preferred network type when the radio works is shown as GSM/CDMA auto. During issue its unknown as shown in capture. Changing from unknown to gsm/cdma auto after failure does nothing.
Of course ttried to turm 3g on/off.... airplane mode on/off.. nothing works except a reboot.
I am on Kk1 radio. I didn't try kk6 as i didn't want to touch the phone in anyway to void warranty. my buddy has same phone but doesn't experience iissue. Same phone, same carrier, same city.
Any thoughts?
Maybe exchange it for a new one? My only advice

Have you tried running logcat to see if there are any logs to suggest whats crashing your radio?
Mine done exactly the same as yours and I am with Orange UK who stated I have a faulty sim card and are sending one out in the post to me so hopefully if that resolves mine you can also ask for a replacement sim card as well.
P.S I found that speediest.net knocks wireless/radio off sometimes and also wireless on mine can totally freeze as well so hoping this will be fixed asap by google.
I have same issue - loosing signal completely just with no reason very often. Turn phone off/on - works fine. I have brand new sim card and phone from Handtec, Vodafone UK.
Ditto for me as well. Purchased from Expansys, second round. It will move between 3G and H then shut off. Happened once so far. I'm using a MicroSIM with an adapter, both worked fine and are new.
I'll be watching this very closely. Someone with a Google account can post this to bring it to their attention?
Happened a second time but came back on. Attached a screen shot.
It does happen where the signal is lost, then comes back. That could happen few times before it goes down and then never comes back up at all. I used a program called signal alert to tell me when. It happens. I found that during the day signal is fully lost a number of times but it comes backafter less than a minute. at some point its lost and doesn't come back and only reboot fixes.
Bmstrong, the capture u showed me shows you lost data, but it seems you still have voice. Look at the screen I posted, u can see no bars what so ever in my signal meter.
When the issue occurs, its random, so by the time I find out and i ran alogcat, I would have missed it. Alogcat only shows me few minutrs before. However, I kept looking at alogcat after the fact and there was nothing that i could see that explains this.
I did try another sim while the trouble is occurring and no use.
I have requested rma from where I bought it and just waiting for authorization. Will share my experience with it and the store after.
Thanks,
Bmstrong, go to settings and about, then status to see if it says radio off. If it doesn't then it either your really lost 3g..maybe coverage or a different issue. In my case radio says its off and never comes back.
sorry to post a little off topic. but how do you see the first screen in the OP's post?
I'm getting this issue too, does anyone have any more information or has resolved this?
When going into the phone info screen does pressing "turn on radio" work for anyone? I have to do a reboot before I get signal back.

[Q] Cellular radio "freezing" after 1.28 update

I have owned this phone only for three days now, coming from a DHD.
Today I installed the 1.28 update and since then my cellular signal has been all over the place. I normally get a solid 5bar HSDPA signal where I live and since the update I have had nothing but issues.
My Sim card seems to be rejected (I am baseing this around the fact that when the radio seems to cycle I get a message saying "preparing sim") but aso it seems to just lock up entirely. Earlier I thought I had a signal only to make a call and have it fail, I tried to cycle the power to the radio by putting the phone into airplane mode but this didnt work so had to do a hard reset which then allowed me to make a call, but the call froze after 5 minutes, again with a seemingly locked up radio.
Any one else got these issues, as my phone is effectively a small but expensive tablet at the moment!
I have that issue BEFORE the 1.28 update. The other day my wife rang me at work and whilst we were talking we were cut off but my phone still showed as connected with signal. I figured she maybe lost signal herself. I tried to ring her back both on her mobile and the land line and my phone would not ring out (as far as I was concerned) I tried to put Airplane mode on but it didn't work so I had to reset the phone.
I haven't had it since but the strange thing is even though the phone didn't give me any indication that it was ringing out my wife said that both her mobile and the land line rang.
It seems strange that I couldn't toggle the radio/airplane mode or hear anything but the phone did actually ring out. Maybe the issue effected the radio and speaker? That's something to test if yours does it again. Ring a phone nearby to see if that does actually ring?
Update from yesterday, I currently have a signal as I am typing this, if however I make a call it will connect and I can listen for a second then it drops with the signal dieing. Followed right away by coming back up.
A reboot seemed to fix it for the moment, but not sure how long for. Next step is a factory reset for me and see how I get on from then.
AFAIK, the radio isn't updated?
I have taken it back and swapped it for another one now. Just waiting for it to charge then I am going to do the FOTA update and then install everything. So far though so good and the three calls I have made/recieved worked perfectly.
Seems to have beena faulty handset *fingers crossed"

[Q] Shutdown issue (but not the overnight one!)

Hi,
I've been reading the other shutdown issue with interest from the start but I think that my particular issue is different and I'd like to know whether anyone else has my exact problem.
I'm using the o2 UK 16GB version 10A/234 and this is the problem:
When I reboot the phone and it gets to the lockscreen, if the network status is "disabled" on the lockscreen and I swipe to open, the phone shutsdown and can't be started again until I remove the battery.
If I wait for a couple of seconds when the lockscreen comes up, there is a little lag but the phone works as normal.
I can replicate this issue over and over again, so it is not a random occurrence AND this is the second handset that I have had where this exact problem is present.
Does anyone else have this issue?

I'm facing the same issue. Is your device rooted?
At first every (re)boot without being connected via usb to a charger or a computer would result in a shutdown shortly after I enter my pin. After a day of usage I cannot reproduce it anymore, although it still happens from time to time, for example yesterday when I tried to send a text while having very bad to no reception. When it happens I also have to remove the battery or hook it up to a charger, otherwise the buttons/screen would not respond..
I'm thinking there is a (firmware) problem with the chipset since it always happens when my phone is trying/strugling to connect to the mobile network. I installed an app which constantly writes logs to my sd, hopefully that will give me more information about what's causing the problem..
Are you also having bad reception when the device shuts down? My previous device (iPhone 5s) had normal reception in my house, incl. a stable 3G connection, always 2-3 bars of 5. The LG G3 is constantly strugling with the connection to the network and often switches to "emergency calls only"..

This happens rooted non-rooted, stock (no added apps) and always whilst connecting to phone network. Are you on same variant as me and if you leave it for a moment before putting in your pin does it then work ok?. I'm trying to get o2 to change my handset for another model (m8) but they just want to fix my one.

Yes I'm on the same variant. Still running the 10A firmware.
Sometimes it works, but I will do some more test this evening after work and see if I can reproduce it every time and hopefully get some usable logging too.
I think this is fixed in the 10f firmware update that I installed yesterday. I haven't had a shutdown since :victory:

[Q] Watch continues to disconnect?

Has anyone else experienced frequent disconnects between the watch and the phone?
It was happening with my modded Note 3, which had a custom kernel so I was thinking it may be that. But now (for 2 weeks) I've been on a stock Note 4, and it keeps happening. Every once in a while, once a day or maybe once every two days, the phone and watch disconnect.
Android Wear says "connecting" but never does unless I click on Disconnect and then click on Connect, at which point it connects immediately.
I had "Find My Phone" installed, which would notify me when I got disconnected, so I thought it may be that. Uninstalled it a few days ago. Still happens. It's not a huge deal, but it's annoying and I don't see why it should happen.
Any idea?
Noticed the same with my 360 and Nexus 5. Both on stock latest versions.
Issue with mine is that the Moto360 constantly says Disconnected when trying to connect to my Note4. I click connect, it says connected and then quickly changes to Disconnected.
Been trying to figure it out for 3 days now.
I think I realized that the issue is in reconnecting.
I still don't know why sometimes it disconnects, but disconnecting itself wouldn't be an issue if then it proceeds to reconnect on its own.
But I realized that when I'm at home, I leave my phone by the computer and walk around. If I walk outside of the bluetooth range, then it disconnects. That's fine. But then it should reconnect when I come back into range, and it never does. It says "Connecting" and never reconnects unless I do it manually as I said in the OP.
So I guess the question becomes: why does it get stuck on "connecting" when it's in range and should be connected? Is this a Samsung issue or a Moto360 issue?
I have seen the same issue with my Moto 360 and an original Moto X. It normally reconnects but then once in a while it just won't. The easiest solution I have found is to turn bluetooth off and then on again on my Moto X. That always brings it back, a reboot of the 360 does not.
Well as I said in the OP, if I go into Android Wear, click Disconnect and then click Connect, it works. But there is absolutely no reason why it shouldn't auto-connect. If it disconnects, and I don't notice, the rest of the day I go without notifications until I realize the watch has disconnected. That's not how this should work.

Hi, i have the same problem, my watch always disconect to my phone (moto x), and then the bluetooth system never start again. When I enter in setup ---- bluetooth---- the bluetooth switch doesn t turn on again until phone reboot.
this is so annoying. and it seems like there's a few people experiencing the same thing but nobody seems to have hit a solution. I have yet to come up with one. if I do, i'll post on here.
Same happens with mine. It just prompts me with a "connect" screen on my phone once in a while. After connecting 2-3 times, it won't appear until next time I turn off Bluetooth.
I get this problem about 2 times per day...running with a Note 2 running 4.4.2 stock but rooted....
