i have a dilemma.. i just recently got the N-9005 model of the Note3 from one of our local carrier in the philippines (globe telecom) on a contracted account.. its been 6 days now since i have the Note3 but during the first 2 days i was enjoying the LTE speeds ranging from 10-20 Mbps constantly in our house which is pretty much as fast as how much my GalaxyS4 gets while on LTE.. which basically shows that they were both getting the same download speeds every single time before the note3 update disaster..
then i noticed after 2 days of enjoying the phone that the MJ7 update is available..
so i did a master reset on my device first before doing the update (without reading any downsides from XDA ) which basically restored the phone to stock settings without any accounts or apps installed besides the ones that were already pre-installed..
i tested the speed after the master reset before doing the MJ7 update and i was still getting the 10-20 Mbps speeds..
so basically its ready for a clean official firmware upgrade to MJ7..
after downloading and installing the MJ7 firmware without a hitch.. the first thing i downloaded was the Speedtest.net app to test the improvement on the connection speed..
guess what.. it f*cked up my phone's LTE speed!.. now its mostly getting around 2-8 Mbps download and upload!.. and the signal became much more weaker compare to when i still have the release firmware!.. and it looks like the H/H+ speeds also deteriorated by about 1-2 Mbps difference from the previous release firmware..
so i thought it probably just needs to go through a master reset after the software upgrade.. so i did a master reset again thinking it just needs to be cleaned after the firmware update.. SAME THING happened again.. slow 2-8 Mbps LTE speeds..
then i thought my carrier throttled my LTE speeds.. then i tested my wife's LTE speeds using the Speedtest.net app.. first testing it on my old GalaxyS4..
she was getting around 9-18 Mbps.. so i tried to insert her microSIM in the Note3 to test the speeds and again i was only getting 2-8 Mbps on the Note3!..
so i inserted my microSIM in my old GalaxyS4 to test the LTE speeds.. guess what.. my trusty old GalaxyS4 was hitting 10-20 Mbps EASY on multiple tests with just 1 bar of 4G LTE signal!..
take note that both of our carrier services are postpaid accounts and have the unlimited LTE data services (no throttle limit)..
i also made sure that both devices were tested using the same location (side-by-side simultaneous test) and using the same local server to ping..
it looks like the MJ7 update screwed the signal and data performance of my Note3..
now i was trying to do a firmware restore using Kies3.. and another issue happens..
its stating that ['GALAXY Note3 (SM-N9005)' does not support]
im like WHAT THE F***?!.. SAMSUNG does NOT support their own products?!..
please be reminded that the phone is a VIRGIN.. i have NEVER EVER rooted the phone yet.. nor have i done any flashing of any ROMS or kernels or anything on the unit since the god d*mn thing is just 6 days old..
info of both phones and the way i tested the issue:
Note3 is a virgin (no root ; no custom firmware ; no custom ROMs).. no apps (except preloaded) or emails (except the primary) or samsung accounts or SDcard..
GalaxyS4 is also a virgin (no root ; no custom firmware ; no custom ROMs).. loaded with apps and games.. about 5 emails with autosync.. samsung account with autosync.. with an 8GB microSD card..
tested using the same version of Speedtest.net app from the Play Store..
using identical local server for each of the test to avoid latency discrepancy..
tests on both phone were done simultaneously side-by-side..
both were set manually on "LTE only" settings via *#2263# code..
tests were done on atleast 3 separate servers with 2 speedtest runs each..
Note3 does not have a case while the GalaxyS4 has a custom flip cover during the simultaneous side-by-side test..
each test shows that the GalaxyS4 is around 5-10 Mbps faster than the Note3..
*i attached side-by-side pics of my Note3 and my old GalaxyS4 (with my wife's SIM) with the speedtest.net app results..
---- i hope someone could help me out or enlighten me with this issue..
