Hi, I have a problem with this phone,it works few seconds or minutes and then turns off.I've changed the battery but it's still the same.When I turn it on that Samsung sign rotates and suddenly turns off.Sometimes it starts to vibrate and you have to take out the battery to stop it.Does anyone knows what may be the problem? Thanks
geek, 24 Sep 2014Thanx for ur quick reply..
I will try it & see if it helps but at the time of purchasing ... moreDoing factory reset doesn't change your firmware. So you'll still be on 4.4.2.
The battery may degrade in 1 year if you use it a LOT.
A factory reset after a android upgrade is recommended.

Any phone can only focus on subjects greater than 10 cm from them.

Does the battery gets damaged in 1 year?
And when I done the factory reset the OS version remain as it is i.e. 4.4.2

samsung -tech experts are NOT basaed in each city as you think .. samsung tech support is nationalcentres in each country - you can telephone or send email for tech info regarding your s4 .. you can actually email SAMSUNG HQ in korea ..
ps- battery drainages is fact of life in all smartphones 2014 ..power hungry apps ...you are polite and proper .. cheers .
Anonymous, 23 Sep 2014SO U CLAIM TO KNOW more than samsung tech experts !!! ha ha ha ..btw- s4 battery gives low bat... moreSure enough, S4 will give a low battery alert at 15%. But if the battery is not calibrated properly, this alert may be issued by the system when the battery holds, say, 25% charge.
There might sometimes be a discrepancy between how much charge a battery actually holds, and what the Android system thinks it holds. Any alerts that the system sends out depend on the latter.
The whole point of calibration is to correct this discrepancy.
Samsung guys know of Android as much as the average TV technician know of the electronics of semiconductors. If you have found an exception in your city, then consider yourself lucky.

Those people are just people who market the phones well and act like they know so much. All in all if you give them the phone for repair, they'll just backup the data, do a hard reset and flash the latest firmware and then restore data. They know nothing much except that.
i'm not claiming that i know a LOT but at least i know more than them as they know very little.

If it doesn't, get a new battery. A new battery costs around 1000 INR( 18$).

However, you should change the battery as the newer battery gives a much higher time. I never got 5 hour+ on my older battery but the new one easily gets upto 6.

Anonymous, 22 Sep 2014darkgamer- 1- lithium ion batteries have NO memory gauage set ot reset as you advise .. s4 bat... moreSorry to be butting in, but I thought I should say something here, for I myself have gained about 30% battery life by the procedure darkgamer has outlined. Li-ion batteries have no memory effect - absolutely right, which means 2 things basically :
1. We can charge the battery anytime we want, it matters little whether it has 40% or 80% charge.
2. Therefore the 500 charging cycles that you have rightly mentioned can each consist of several partial charging-discharging. This is in stark contrast to Ni-Cad batteries which should ideally be discharged to near 0 before charging again.
Calibration is a different thing with a different purpose. Although the battery doesn't have a memory effect, after several partial charge-discharge, the battery.bin file may reset itself with the result that it will send out a critical battery alert when maybe the battery has 40% charge in actual fact. It has nothing to do with the battery, but how the Android system interprets how much power is left. The same is true of laptop batteries - they also need to be calibrated once in a while.
And dear, don't think the Samsung guys know everything. I am rather tempted to say, based on my 3 encounters with them in 3 different cities, that they know next to nothing.
Anonymous, 22 Sep 2014darkgamer- 1- lithium ion batteries have NO memory gauage set ot reset as you advise .. s4 bat... morePure BS you got there.
The issue the guy is telling there is a clear indication that either the battery is faulty or it's not calibrated.
If the mediaserver was running in his background I'd doubt that he would get even 1 hour on-screen time but he's getting 3.
Don't comment on things you have no idea about. And spend your time in learning english rather than writing BS here.
Yes, I can be rude.
