My sister bought a Galaxy Trend GT-S7560 a while ago, and she has always complained about lag, and her phone does have some ROM troubles, she sent the phone back to the shop, and it came to her hands with the same problems, they say it has a ROM problem and they can't fix it, since I've used Cyanogenmod ROMs on my phone, I thought about installing cyanogenmod on her phone, it's still in warranty, so I came here to ask for some advice on what to do.
Do you think I should try to install a ROM or not? If so, can you advise me on a good ROM?
