Absolutely you can.
Well I started with a Samsung Fascinate which was Top of the Line when I bought it.
It was an awesome phone for some months. Then I started noticing it freezing. Then it would decide one day after dialing a number to do nothing more, just sit and pause. Id have to pull the battery. Then it would make a call.
It would freeze in the gallery at times, had to pull battery.
Id notice it would get incredibly slow between backing out of one App to open another.....had to pull battery.
Battery pulls were always a quick fix, for a couple days.
And yes, all Apps were closed....and I always kept an eye on the Running Services menu too to ensure even when task manager showed closed they were not still running....which several apps were at times, had to Stop those.
Which was another nagging issue....the need to constantly close apps to keep battery up and performance up.
So after getting tired of that, I went and they sold me the latest and greatest Charge.....the Verizon replacement to the Fascinate. Touted and the fastest 4G phone sold at the time. I tried it out and on day 8, started getting same BS as I did on Fasc. Screen getting jittery, wasn't smooth, slow and of course the need for dreaded battery pulls.
I went back and they swapped it for the HTC Thunderbolt......the other salesman said it was actually the best Droid available and how Samsung was garbage. I was assured Id be happy.
To start, battery life was insanely low. I had everything turned off and barely made it home from work with little use. Tag this thing for an hour and it ate 50% of the battery, slide through some 4G and its history.
Then, the force closes started. Apps hanging up, jumpy screen.
I had enough. I was convinced this is just Droid, so if I'm gonna be stuck with droid, I'm gonna keep same phone and not be out anything.
Ive dealt with 2.1, 2.2, 2.3 and all was same....why should 4.0 be any different.
I returned for a refund and had my Fascinate back running.
I wiped it, Factory restored it and put in a class 8 Micro card to help speed things up.
That worked for a week......WITH NO APPS INSTALLED AT ALL!!!!!
And I'm not a heavy app user/installer. I even abolished Facebook App because it always ran in background, even when closed out of task manager.
Then in middle of night, Verizon decided to give us Gingerbread......OH BOY.
And that's where the beginning of the end was for me and Android.
The battery life went to crap. Then I started getting this deal where it showed it was connected to a USB cable....even when it wasn't connected to anything.
Then in middle of night on 98% charge, it turned itself off. I was late for work......cause the alarm wont go off if the phone is off
This phone would not boot unless you first connected to charger, then it would boot, remove charger and it showed good charge.
Verizon updated the Kernel, and yes, another factory reset. it did not help.
I did one more and that fixed it.......for a week. Now its doing everything again.
At that point, I filed for divorce.
I went that night, added a line and bought myself an iPhone 4s.
Its been bliss since I said
I do
My new iPhone 4s runs so smooth. Smoother than any phone Ive ever used. Its very fast, the wifi speeds are faster than on any of the three other phones.
Call quality is phenomenal. battery life is very good. When I download an App, it works.
And now I don't need to close an App every time I'm done. It runs the same speed with all open or all closed, battery life too.
Sorry for the long response, but you asked for it
