do we need to format if we jump from one ui 2.0 to 2.1?

normally i would if it were an android major base like 9.0 to 10

Guys, I've been experiencing lag and stutter with WhatsApp since yesterday. Even lag when switching between chats, status and calls. I have updated to the latest.
Anyone knows what's going on?

so far i only experience lag on chrome browser. had to resort for samsung browser. but it only happened for lowyat website. funny. But urs is not good news. i wonder what happened too.

Yes, is SAMSUNG Internet browser.

Give it a try if you are not using SAMSUNG Internet.

I just share my experience only.

Software update is rdy to download. Chiong arrrr

Updated!
But it makes my phone so HOT!

my phone temp was ok tho. its abit warm thats all.
optimizing 470 apps
ahaha will need to remove some apps later.

will clear cache also

oh yes i dont know how to say but i feel its better than the previous one.
i choose skeyboard as they got numbers on top i think

honestly i off the vibration .

think to save battery but also not used to it.

im the vibrationless guy haha.

i think samsung keyboard got extra feature like undo and redo also go tips to learn

which one is better for touch sensitivity and finger print scanner?

Can you show me where you bought it ? Tq

i use the most unconventional one
Mobile outfitters (hyrdogel type)

touch sentivitiy good, scratch leh macamplastic la.
FP no issue.

get a good case if u scared of scattered glass

the one on the top and btm (spen) may be damaged if ur case is snap on not properly. the front and back ones are ok tho. i bought full package hehe

front one its like plastic to be honest. i have been using 5 months. i change once due to micro scratches. i use with casing so usually wont have much scratches.

oh if u using spen change to a softer tip. it might help. i realise the one comes with the spen are abit harder which makes plastic/hyrdogel surface to scratch faster.

PS: sometimes i abit OCD.  i will off my screen than shine light at it at certain angle to see those microscratches. to be honest it does not distrupt anything when the screen is on. only when the screen is off u can see. oh well. what is seen cant be unseen hahah

i have been using TP on other phones. one thing good is no micro scratches or hard to find microscratches.
but crack lines and chipping at edges tho.
cant avoid that.

no perfect SP i think.

Hi guys. A question here, I realized I could not download many apps that I used to have back in Huawei P20 Pro (E.g. AXA Flexi Drive, Prudential Pulse and etc.)

Do you guys know why would this happened? Any solution for this? Thanks!

That's the issue. I can't even find these apps in the first place 

Why is this happening? My model is SM-N975F

How did u guys put ur sync settings?
Always on or not?
if yes is there huge difference is battery life?
if no , do u guys put any widget to enable manual sync

my standby time is really bad. 1% per hour during sleep. no wifi, no sync, no location, and all apps closed. and i also notice that the battery will drop from 100% to 98% within 1st hour after unplugged from full charge, with the above settings.

Finally after one week my battery is fully optimised.
8 hour SOT the whole day.
Unplugged at 8 am today.
A few hours on data 4G+.

Now left with 14% battery.
The new update is just so good on battery consumption.
