    My note4 also has a weaker signal after the lillipop upgrade. I usually have 3 bars of signal strength in my room, but I only have 1 after I upgraded. App crashing and battery drain is my worst prob.

    SPEAK TO YOUR CARRIER. This isn't a Lollipop issue but a carrier one. It's unfortunate it happened after you updated the phones OS but again the two aren't related otherwise all the Note 4 users would be complaining of the same thing.

    I think with Samsung Galaxy phones you to different variants of signal one for data the other actual phone calls. in places where you have very low signal try to place a call to someone and see if it goes through look to see if the quality of signal increases if you had no signal at all you would see a circle with a line across it and a notification unable to make a call would appear on your screen with some updates there some things that they take away some people have said that after doing the lollipop update there signal has decreased another thing to consider is to try and replace the sim card and see if that helps or avoid standing under overhangs

    I went back to kitkat a couple days ago. Battery is amazing once again. Signal is much higher better and constant. With lollipop I was struggling with signal strength therefore killing my battery especially in sketchy service area.

    If you've accepted the major update that Verizon and AT&T have sent out in the past few weeks, you won't be going back to KitKat. I tried the XDA thing 2 days after the Verizon update and it would not work, because of the update!

    Just thought I'd share a potential solution.

    I have a Note 4 on Verizon running Lollipop. I changed the preferred network mode and it increased my signal.

    Settings > More networks > Mobile networks > Network mode.

    I had to change it from "GLOBAL" to "LTE / CDMA".

    I'm facing a similar issue here in India since the lollipop update. I am using Sony Xperia Z2. I signal keeps randomly dropping off. Even when there is signal, the voice clarity is pretty bad.

    I believe you are absolutely correct. My Verizon Note4 signal strength has dropped noticeably for cel reception AND for GPS reception after lollipop. Used to make calls from basement. No more. Used to receive at least 5 sats for GPS sitting on couch. Receive zero now while two Samsung tablets on 4.4.2 receive over 7 sats. I also tried factory reset. Can't go back to kitkat due to locked bootloader.

    So glad I found this thread -
    In Sept 2015 I bought a New NOTE 4. I've experienced same problems as comments above, and sooooo much more! I've invested hours and hours during the past 3 months troubleshooting with Vz & they have escalated my case and filed numerous problem tickets. Vz has sent me TWO replacement Note 4's and a THIRD is on it's way. Had me do at least 10 factory resets, and replaced the battery, and the simcard. They even had me take out the memory card for several days to make sure the card is not the problem. Calls drop often, bars dance from 1 to 5 bars (and I'm not moving), phones reboots often, and the 1st replacement even did a factory reset all by it self. The CLOUD has been a nightmare on all three Note 4's I've tried. It does not download my messages, call history, contacts, etc and freezes the phone and causes it to reboot. The crazy thing is My old Note 2 uses Android 4.4.2 and I am carrying it with me right now because IT IS RELIABLE. (The Note 2 shows full bars & the Note 4 shows 1-2 bars and both are side by side. An this happens at both my two homes that are 100 miles apart, including my office that is on the coast). Vz tells me its the antena and I need to buy some stronger antenna services for $100+/-, but again why does the Note 2 not drop the calls? So the i will get the FOURTH Note 4 in a couple of days. Not sure what VZ thinks will be different with it. Sooo Disappointed!

    Definitely disappointed, I've been a Verizon customer since 09 and in the process of switching to cricket and getting another unlocked note 4. Never thought about changing providers until this update. It has completely killed my service in areas where I always had service before. Now dropping calls, missing calls that never rang. They lost me as a customer over it.

    My wife and I both have note 4 and on lollipop and both have exact same issue that started at the same time. However my S5 on lollipop is much better.
