Hi sir/mam I have a samsung galaxy duos running android version 4.2 im having trouble of the slowness of my phone , so I search on the internet of some tips to make my phone better so I found out that galaxy duos had a issue or problem on android version 4.2 so I had to downgrade my phone to make my phone better based on what ive seen on the net. So after I successfully downgrade my phone using firmware from Taiwan ny phone is faster now . App runs smoothly but I noticed that my battery life is now draining faster than before . Now I wanna know if this is due to firmware from taiwan? Second is there any method to improve my battery life? Or do I need to install other countries firmware? Btw im from Philippines, ai did not install firmware from ph bec of the carriers lock.

[Q] Galaxy Tab 3 LIte SM-T110 Update?

Just been bought a Galaxy Tab3 8Gb Lite SM-T110 fro my Daughter so she can use a Jawbone up Fitness tracker. We didnt realise at the time that the tracker only works on Androind 4.3 and above but the TAB 3 comes with 4.2.2. When i try a software update is says there isnt any. Is there anyway to get at least Andoid 4.3 onto this device and if so has can some one point me in the correct direction? I keep looking but seems most i can find always say updating to 4.2.2. I dont mind if i have to Root the device.
The lastet Version is V4.2.2 for the Tab 3 lite,also we havent got a Customrom with higher Version.

[Q] bell galaxy note 2 problem

Hi guys , I have a bell galaxy note 2 (i317m) which I upgraded to cm12 (5.1.1) nightlies cyannogenmod using latest TWRP recovery .
This is the story after I upgraded to cm12 5.1.1 my model number now says gt-n7105 . I ve lost functionality of the s pen and want to go back to kitkat, everything else works
I played around with lollipop for a few weeks but there are a few things about it that irk me , so I want to downgrade back to kikkat .
My main question is can I downgrade using a stock bell kitkat rom , using odin or will that brick my phone ?
My build number is 51.1 LMVF7V if that is important .
I don t know if my bootloader is locked but , I guess not because i did put cm12 on it , and if it was locked it would have bricked.
If you need more information , i will find it.....thanks for any help in advance.....

Stock marshamallow or Nougat

Hello
Earlier I have posted about my problem with changing the locals to USA .. and the phone Sim slot one was not working .. sent the phone back to service .. and they have replaced it for me .. lucky me
Anyway .. I have seen the nougats .. worked with it several days .. do you experts advise sticking with marshmallow till my oem is unlocked and I take nandroid backup via twrp .. or update anyway ?
From your experience guys .. Im. Proud owner of Vibe P1 .. and got used to MM
Nougat all the time. The phone is performing even better after the Nougat update. Battery life is way better too.
I much prefer Nougat to Marshmallow.
Very stable and great battery life.
