I have been using galaxy s5 user for more than 2 years and switched to vivo Y55s last 6 monts ago. I LOVE THIS DEVICE!
1. The screenshot option is AWESOME amd userfriendly!
2. You can even record your screenshot! With or without sound/audio.
3. Touch is AMAZIngly and surprisingly GOOD.
4. NO HEATING EVEN AFTER 6 MONTHS.
6. CAMERA IS GOOD.
7. BUILT IS strong. Drop my phone without cover from some height by mistake, surprisingly Survives 4/5 times.
8. Customer service have polite agents. My charger pin has issue after 6 months, i went to vivo service centre, although passed 4 days of validity, the agent help me out with new wire saving me 120 bugs.
Y55 has a size that is neither too big nor too small, which makes it comfortable to hold even those with small hands. It has a chrome lining on the edges that adds extra grip while the back has a metallic matte finish that repels smudges and fingerprints well.
