will a screen protector for a different phone model work on my phone?

Q. My phone (the lg optimus logic) does not have screen protectors anywhere. I've searched multiple websites so I was considering getting one for a phone that's larger than mine, such as the galaxy s3 (http://www.zagg.com/invisibleshield/samsung-galaxy-s-iii-cases-screen-protectors-covers-skins-shields.php). will this work if I cut it down to the size of my phone?

A. These types of phone accessories normally come with a listing on the box of what model phones they are compatible with. While most smartphones these days look very similar to each other, there are subtle differences that make one type of protector incompatible with many phones.

Based on your question, you are trying to use a protector that is made for a larger phone on a smaller device. There is a very high degree of probability that the protector will not be compatible with your smartphone.

Q. so now i am using a samsung galaxy S3...... and i feel that this phone is just isn't right for me... i don't feel comfortable using this phone...... so.... probably i will change my phone as soon as my phone break...... so what should i change y phone to ?

i would love to have a corning gorilla glass cover and a phone that really pops the color from the sreen

i have my eyes on
Sony Xperia V
Nokia Lumia 920

Q. I just received the phone. Im reading the manual page after page about the battery with magnifying glass. Is this a spare battery or is this the one that goes in the phone now? I never work on these phones because I have had my work phone for years and someone else takes care of this.

How does the battery get in the phone? Ok I see no seam to get in. I dont want to break this phone and I have my magnifying glass out reading the manual. My other old piece of crap phone is easy.
I did go on Samsung website about this question and I dont have the answer.
Ok I want to charge the phone NOW and I am so EXCITED about the new phone I'm being impatient!!! LOL
If this were my work phone I would be prying the hell out of it and figure this out myself. But this is my new baby...
Thanks Steven...I am just afraid of breaking it....I am looking. Ok It is not giving way it wont budge...Thats why i thought i was in the wrong place.... I will call samsung.
Samsung feels my phone is defective. So I wasn't crazy after all. Lol
My electrician was here today doing work and I asked him to help me- he handed the phone back to me and said he's not sure why the back wont open. so this is resolved. Thanks and I will send for another phone.
