Mobile network signal - Xiaomi Redmi Note 3 Questions & Answers

I'm not sure it's a problem, but is anyone also facing a similar situation. I'm on Orion OS(also happens on krexus-caf) if I go to battery settings and click on the graph, my Mobile Network signal is almost fully orange. However my signal bars in status bar are almost always full, and an app(Mobile Signal) shows a good dBm, around -70. So I checked by typing *#*#4636#*#* in phone dialer then -> phone info and it shows around -70dBm but after a few seconds it drops to -113dBm(which is lowest possible), then back up to -70 then down to -113 again. Is anyone facing a similar issue?
Thankks

[Q] Frequent random no service on ATT

I recently got Samsung GS2 to use on ATT in the US. Overall the phone works very well, however I keep getting "no service" at seemingly random times in known good cell reception sites (like my house). The phone appears to be working fine with 3-4 bars and then all of sudden the signal drops and I loose all connectivity for anywhere from 10 seconds to 3 minutes (wifi appears unaffected).
Here's what I've tried so far:
-Running stock KE7
-Downgrading my baseband to NEKD5
-Selecting "GSM only" in my network settings
-Disabling fast dormancy
-Running Lite'ning ROM just for kicks
None of these make the problem go away.
Please lmk if there's anything else I should try. Thanks in advance!
I am having the same issue on Vodaphone in the uk. Seems the only way i can avoid it is to hold the phone with finger tips top and bottom and not grip around the back! This also seems to improve wifi signal.

My problem doesn't seem to be related to how I hold the phone. I've tried holding it several different way, plus just keeping it laying flat on a table and it doesn't seem to make a difference...
I have a similar issue:
whenever I loose my 3G connection and there is no roaming GSM available the display show a "stop icon" in the upper display. That's ok... The problem is that when I put it where I know for sure there's the signal it won't reconnect but seems to stay disconnected (no service) forever! I have to force a Airplain Mode ON/OFF to make it search and catch again the signal in a few seconds. Never rooted the phone, official KG5.
My settings: WCDMA + GSM, packet data on (when in 3G, no roaming data allowed). H3G Italy.
I know at least 3 people who reported the same problem in Italy with different carriers.
Whenever it looses WCDMA + GSM, it hardly reconnects to the newtork leaving the phone in "No service", totally offline from calls too....
Finally fixed starting from fw KI4+!!

Pulid F13 loss of the GPS signal with active screen

Hello to all.
I write from Italy for a problem with my gps smartphone, asking for help to the most experienced of the web site.
I purchased from a dealer of Chinese aliexpress a Pulid F13, 2gb ram, 32gb rom, mtk6589T 1.5 ghz, display (1920x1080) I'm in difficulty in solving a problem with the GPS PULID F13 just received, the problem is in the process of engagement signal that does not start immediately, but the strangeness of the situation is that the navigator started looking for the signal and can not find it, it goes into standby mode, the display goes dark, and that after a few seconds I hear the voice of the guide that tells me the locked signal, then display active, I go to the browser and after a few moments I lose the signal, then I found that every time the display turns off the GPS signal is resumed. Does anyone have any idea how to solve the dilemma of this strange smartphone? I tried all the fixes also possible by replacing the file gps.conf in direrctory System / etc, but I also disabled gradually the whole wifi, data, and put into airplane mode, but nothing nothing usually result display on screen and active after a little lost gps ... Possible that there is an interference between the display and the GPS signal?
Thank you for your help.Pulid F13 loss of the GPS signal with active screen

[Q] Dead GPS when out of the country

Bizarre issue on SCH-I545 CM11 jflte nightly from April'15 and then on several CM12.1 jfltevzw nightlies from April thru mid-June'15: The GPS receiver works fine here in Phoenix, and in Portland, NorCal, etc. When I travel to Korea or Germany, or Costa Rica (GSM, not CDMA locations coincidentally), then the GPS seems like is it completely disabled / non-functional. GPS Status flashes up the active/searching icon in the notification bar for about 1 second, then it goes away. The GPS Status display shows zero satellites forever (tried for 10min). Not even one satellite showing on the signal strength bar or radar map. Zippo.
Tried deleting, resetting and downloading A-GPS data (via a wifi connection, not mobile data) does help. Note that I have mobile data roaming off, but cell service on and I can make/get calls and texts. Arrive back in the States and the GPS works again. Can't debug something that ain't broke! Damn it!
I'm not finding this issue in any forums. Is this a known issue? I'm on the MDK Baseband version. Will changing the modem package potentially fix this? (is it possible to change the modem SW without changing the bootloader from MDK?)
I read somewhere that the GPS radio may be on the same chip as the CDMA radio, and as soon as the phone figures out that CDMA is not available it disables this (portion of) the radio chip thus the GPS is disabled. To test this theory, here's my plan… Traveling from Phoenix to Munich tomorrow. When I land before taking the phone out of airplane mode I'll fire up GPSStatus and see if it is seeing satellites (and see how long it takes to lock). If so, then take it out of airplane mode and see if the GPS reception gets killed.
Other thoughts?

Clues
So here's the deal... I flew to Munich and sat in the airport courtyard for an hour dinking with my phone. First, before turning off airplane mode I tried to get a GPS lock. I let is sit for several minutes with no satellites found. I turned airplane mode off and the phone got on the local GSM network and I got the usual welcome message with usage rates. Data roaming was kept off. After a while of poking at various menus with no luck, I switch airplane mode back on and wallah! GPS reception. As soon as I turned on the voice/text cellular radio then no GPS reception. Very repeatable.
However, some menu that I had poked at made the phone not get back on Verizon when I came back home... "No service" in the notification bar. LTE data with strong signal worked find, but no voice/text service. Popped the SIM out and back in with reboots, and no luck. The only fix was to go back to recent CM 12.1 nandroid backup and everything is now fine.
I recall that previous to the nandroid reload that the Mobile network settings > Preferred network type > did not have the Global option once returning to the states. Global now shows in the menu on the 6/23 nightly.
Thoughts?

Mobile network signal stays on when phone off????

Not sure if this is a bug or not, I switch my phone off at night, but when I switch it on the next day and go to battery use, it shows mobile network signal has been active during the switched off period, is this normal behaviour
Bug, or is there malicious hardware installed by Xiaomi to spy on us?

Annoying Loss of Signal notification

My phone bleeps whenever I lose signal and then bleeps again when the signal returns. This happens even when on Wi-Fi. Its so annoying. I think I'm on 5.1.1 .
